Abstract:
A method for screening individuals at risk for prostate cancer progression is disclosed. The method is useful for evaluating cells from patients at risk for recurrence of prostate cancer following surgery for prostate cancer. Specifically, the method uses specific Markovian nuclear texture factors, alone or in combination with other biomarkers, to determine whether the cancer will progress or lose organ confinement. In addition, methods of predicting the development of fatal metastatic disease by statistical analysis of selected biomarkers is also disclosed. The invention also contemplates a method that uses a neural network to analyze and interpret cell morphology data. Utilizing Markovian factors and other biomarkers as parameters, the network is first trained with a sets of cell data from known progressors and known non-progressors. The trained network is then used to predict prostate cancer progression in patient samples.

     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to fields of computer-assisted quantitative image analysis and methods to classify cells related to cancer progression. More specifically, it concerns methods to detect patients at risk for progression following radical surgery that have been diagnosed with localized prostate cancer by current state of the art clinical pathology and clinical laboratory methodology. Additionally, it concerns using the same approach to predict organ confined disease status using pre-treatment information extracted from the core biopsy materials. 
     2. Description of the Related Art 
     Prostate cancer is diagnosed in 100/100,000 white males and in 70.1/100,000 black males in the United States. It is the second leading cause of male cancer deaths and the most commonly diagnosed cancer in men in the United States representing 21% of all newly diagnosed cancers. In 1993 an estimated 165,000 men in the United States were diagnosed with clinically apparent prostate cancer and 35,000 will succumb to the disease. The age-specific increase in incidence achieves a maximum of 1000/100,000 in men &gt;75 years of age. The lifetime risk of developing clinical prostate cancer in the U.S. is 8.7% for white and 9.4% for black Americans with a lifetime risk of dying being 2.6% and 4.3% respectively. The risk of developing prostate cancer has risen 42.6% since 1975 as compared to an increase of only 26% in risk of developing lung cancer for that same time period. Approximately 65% of prostate cancers are clinically localized at the time of diagnosis and potentially curable with standard surgical techniques, yet only 50% of men are found to have disease confined to the prostate at the time of surgery. Pack and Spitz (Pack R. and Spitz M. A. The Cancer Bulletin, 45:384-388, 1993), reviewing the epidemiology of prostate cancer, indicated several definable risk factors such as age, race, dietary fat consumption, vasectomy, and familial aggregation with at least a two-fold increased risk for first generation relatives of men with prostate cancer (rare autosomal dominant inheritance). These causal correlations, though impressive, can not yet explain the complex etiology, biologic heterogeneity, and rapidly increasing incidence of this disease, and await further investigations of genetic, epigenetic and environmental factors. 
     The mortality rate for prostate cancer has been steadily increasing over the past 40 years and will continue to do so as our population ages. This clinically evident disease represents only the tip of the iceberg in that nearly 30 percent of all men over age 50 harbor a silent microscopic form of latent prostate cancer. Current early detection methods are increasing the numbers of this latent form of cancer identified, which now represent more than 11 million cases within the male population in the United States, and growth rate studies indicate that these tumors appear to grow very slowly and the great majority should remain clinically silent. 
     Recent advancements in transrectal ultrasonography and the development of a serum based assay (prostate specific antigen, PSA) for early detection has caused the diagnosis of premalignant neoplasias as well as prostate cancer to increase at an alarming rate. Many of these newly diagnosed neoplasias could represent the non-aggressive, potentially latent form of the disease that may never have become clinically evident if followed without therapy. Unfortunately, no accurate and specific methods presently exist to distinguish the more potentially aggressive form of prostate cancer from the latent form of the disease; thus most patients diagnosed are presently treated as though they had the aggressive form of the disease. At present, the factors to be considered in assessing cancer progression are estimates and significance of tumor volume, pre- and post-operative histological grading of cancer and high grade intraepithelial neoplasia, clinical and pathological stage, and serum prostate specific antigen (PSA) to predict biological aggressiveness of prostate cancer. These techniques generally have only marginal predictive value. 
     It is well accepted that the epigenetic and genetic transformation of a normal prostatic epithelial cell to a cancer cell with progression to a metastatic phenotype requires multiple steps. The development of methods to quantify accurately these changes in order to better predict tumor aggressiveness has been the subject of much experimental work in prostate cancer. 
     Diamond and associates (Diamond et al., Prostate, 3:321, 1982; Diamond et al., J. Urol., 128:729, 1982) were the first to employ a simple nuclear shape factor (nuclear roundness) to describe the shape of cancerous nuclei for patients with stage B1 and B2 (Whitmore-Jewett staging) prostate cancer and accurately predicted outcome for these patients. Since then several investigators have used this method to predict prognosis for patients with various stages of prostate cancer. More recently, Partin et al. (Partin et al., Cancer 70:161-168, 1992.19) used a multivariate analysis of the variance of nuclear roundness, clinical stage, Gleason score, and the patients age to predict disease free survival among a group of 100 post-operative patients with localized prostate cancer. The use of chromatin texture feature data extracted from either H&amp;E or Feulgen stained sections correlate well to classification of malignant cells. However, the sensitivity of Markovian texture measurements is complicated by the level of pixel gray level resolution (grain). Dawson et al. (Dawson et al., Analytical and Quantitative Cytology and Histology, 15:227-35, 1993.47) used a CAS-100 Image Analysis System and software to measure 22 Markovian texture features at 20 levels of pixel resolution (grain) and found ten features that discriminated chromatin patterns in breast cancer images captured by the CAS-100. Markovian analysis is a method based on determining gray-level transition probabilities and it allows discrimination among different nuclear texture features; the value for each feature depending on the level of grain resolution for each measurement. 
     Christen et al. (Christen et al., Analytical Quant. Cytol. Histol., 15: 383-388, 1991) have applied a linear discriminant statistical model analysis of shape, size and texture features of H&amp;E stained prostate nuclei to a high efficiency, 93% correct classification of normal and abnormal cells. More recently, Irinopoulou et al. (Irinopoulou et al., Analytical and Quantitative Cytology and Histology, 15: 341-44, 1993) employed Feulgen stained nuclei and a computer-assisted image analysis system to characterize digitized images (512×512 pixels, with 256 possible gray tone levels) from twenty-three patients with Stage B carcinoma of the prostate followed for at least three years. Using five chromatin texture features and discriminant analysis methodology, these patients could be divided into those with a good and poor prognosis. 
     In spite of the progress made in evaluating the progression of prostate cancer, it is evident that improvements are needed in the accuracy of such determinations. A particular advantage would be realized by the development of methods that provide for accurate and reproducible statistical analysis of prognostic variables to maximize the aggregate positive predictive value while simultaneously reducing false negatives and false positives. 
     SUMMARY OF INVENTION 
     The present invention provides new and improved methods for determining the biological potential for progression of treatable, localized prostate cancers using core biopsies, fine needle aspirates, or radical prostatectomy specimens in order to: (1) better evaluate which patients have tumors that need any treatment, (2) determine the prognosis of patients with prostate cancer pathologically localized to the gland, after surgery, so that adjuvant treatment of those patients with a high probability of disease progression might begin earlier in the natural course of the disease, and finally, (3) provide more objective means to select patients for chemoprevention trials using dietary modifications, retinoids, and hormonal manipulation (i.e. 5-alpha reductase inhibitors). 
     For the purposes of this invention, progression is defined as recurrence of disease post-treatment (surgery or irradiation), for example in the case of prostate cancer, as determined by PSA elevation, clinical evidence of local or regional tumor recurrence, distant metastasis, or death. Organ confined disease status is defined as prostate cancer that is still contained within the prostate gland and has not invaded the prostatic capsule. 
     In certain embodiments of the invention, a statistically analyzed combination that includes quantitative nuclear image features selected from pathologically important tissue sections and appropriately selected biomarkers provides an aggregate positive predictive value with negligible false negatives and false positives that exceeds current conventional pathological methods. In addition, this approach affords the probability of identifying additional potential utilities for biomarkers to identify progressors with pathologically defined low to moderate Gleason score (≦6) as being of higher risk due to the presence of such biomarkers. Also, select biomarkers served to identify tumors that have extended beyond the prostate gland (non-organ confined disease). The aggregate positive predictive power of the model, all parameters (i.e. quantitative nuclear image features and biomarkers), was achieved using clinically and pathologically well defined, long term (&gt;7 years follow-up) retrospective patient samples. The ultimate goal of this invention is to apply these predictive capabilities to prostate biopsies (both progression and organ confined disease status) and/or post-surgery prostatectomy samples (progression risk only). 
     This invention provides a method to collect nuclear images and extract all relevant nuclear morphometric descriptors (NMD&#39;s), including size, shape, texture (Markovian analysis), and DNA content features. Additionally, other phenotypic cancer cell properties were assessed through the use of antibody probes for cellular biomarkers (e.g. Her-2/neu, Feulgen DNA stain, PD-41 (prostate mucin antigen), etc.). The NMD&#39;s combined with the biomarkers can then be analyzed to construct a non-parametric, non-linear mathematical model (e.g. Applying statistical methods such as logistic regression; discriminate analysis (Bayesian classifier or Fischer analysis); recursive partitioning methods (Classification and Regression Trees, or CART); or neural networks (both standard and proprietary)), that can yield a single predictive probability for prostate cancer progression or organ confinement, with or without conventional pathological grading. The pathologically significant areas are identified by an expert trained in the identification of abnormal cells and tissue architecture associated with malignancies of the prostate. Such abnormalities may be present in core biopsies, fine needle aspirates, or radical prostatectomy specimens that have been fixed using methods that preserve the antigenicity of the biomolecules of diagnostic significance, cellular architecture, and integrity of the deoxyribonucleic acid (DNA) or chromatin. 
     According to the present invention, a method of predicting prostate cancer progression or organ confined disease status is provided, comprising the steps of first obtaining a clinical sample from a subject, then analyzing cell nuclei from areas selected by pathology experts and collecting the NMD&#39;s as well as phenotypic cellular biomarker information, and thirdly, predicting prostate cancer progression or organ confined disease status using non-parametric statistical analysis of the data. Cell sampling for image analysis involves the selection of intact cell nuclei representative of the worst state of differentiation as well as, when present, well to moderately differentiated cancer cells. This provides a measure of tumor heterogeneity often present in prostate cancer. It is suggested that at least 50% of the cells analyzed be of the worst state of cellular differentiation present in the clinical sample, and that the remainder of the cancer cells analyzed represent the well to moderately differentiated cell population, if present, in the clinical sample. 
     In certain embodiments, the resulting data includes biomarker results (e.g. including but not limited to Her-2/neu antigenicity, PD-41 positivity, and DNA ploidy) and NMD&#39;s, calculated based on nuclear size and shape, as well as texture features derived by nearest neighbor relational analysis of individual pixel gray levels to mathematically determine several features (e.g. object sum, picograms of DNA, contrast, correlation, sum average, sum variance, difference variance, difference entropy, information measure B, product moment, and standard deviation). For the purposes of this invention, these parameters are collectively referred to as prognostic parameters. 
     Clinical samples obtained from patients at risk for recurrence of prostate cancer following prostatectomy are analyzed and values generated for various prognostic parameters, including the nuclear morphometric descriptors (NMD&#39;s), Her-2/neu antigenicity, PD-41 (prostate mucin antigen) positivity above a 5% cutoff, and nuclear roundness variance (NRV-DynaCell™). Summary statistics from the NMD&#39;s (e.g. standard deviation and variance) and raw data from the biomarkers are analyzed using logistic regression. The logistic regression may be applied in a univariate or multivariate mode. As used herein, multivariate analysis means that several univariately significant independent variables are jointly regressed on the same dependent variable. A dependent variable refers to a clinical outcome (e.g. Progression as determined by PSA elevation, local or regional tumor recurrence, distant metastasis, or death), or a pathological disease state (e.g. organ confinement status). Based upon significance levels, the statistical program selects only those univariately significant independent variables that contribute to the correct prediction of the dependent variable (e.g. progression or organ confined disease status). Notable is the fact that future changes in the model, such as measurement of NMD&#39;s (e.g. different magnifications for collection, improved camera resolution, etc.) and or additional biomarkers, may change the parameters needed and only improve upon the predictive power of the models by small percentages so it may approach 100%. 
     As used herein, a receiver operating characteristic (ROC) curve plots an independent variable&#39;s sensitivity (true positive fraction) on the y-axis against 1-specificity (the false positive fraction) on the x-axis as the cutoff value for a predicted positive observation is varied. A positive observation means that the predicted probability is greater than or equal to an investigator selected cutoff value. The ROC curve or plot is useful for determining the sensitivity, specificity, and negative and positive predictive values of a single test or a multiparameter test. In addition, the ROC curve can be used to establish the optimum threshold cutoff for a continuous variable. When quantitating the area under a ROC curve, an area of 1.0 means a perfect predictive value, while an area of 0.5 means no predictive value and is due to random chance alone. 
     For the purposes of the invention, sensitivity is the fraction of observed positive cases that are correctly classified and equals: true positives÷{true positives+false negatives}. The positive predictive value equals: true positives÷{true positives+false positives}. 
     Specificity is the fraction of observed negative cases that are correctly classified and equals: true negatives÷{true negatives+false positives}. The negative predictive value equals: true negatives+{true negatives+false negatives}. 
     As used herein, Markovian analysis means a process by which an image (pattern space) is transformed into a transitional-probability space. The Markovian approach to texture measurement treats images as stochastic processes in the form of discrete Markovian fields, yielding matrices of gray-level transition probabilities. These probabilities are arrays of numbers that describe digital images in terms of the probability of occurrence of different gray levels and sequences of gray levels. The current invention uses 22 texture parameters calculated from such matrices. 
     Texture is an important visual feature for many pattern recognition tasks. As used herein, texture describes the interdependent characteristics of pixels within a neighboring area. Regular texture has more or less periodic patterns, while random texture is best described by its &#34;coarseness&#34;. A texture parameter is a local statistic, meaning that the statistic is computable from a set of neighboring picture points in a neighborhood that is small compared to the number of picture points in the entire region. 
     A Markovian matrix of the present invention is constructed using a cell nucleus image captured in the QDA Morphology mode of the CMP v3.0 software on a CAS-200 Image Analysis System. Using the QDA Morphology mode of CMP v3.0 software allows the measurement and calculation of the features listed in Table I. CMP v3.0 calculates 22 different Markovian nuclear descriptors based upon the gray-level transition probabilities of Feulgen stained nuclei. The step size selected may range from 1 pixel to 256 pixels. The step size defines the size of the &#34;grain&#34; or picture point in number of pixels that is to be compared to the neighboring picture points. Each cell nucleus image is normalized by partitioning the image into eight equally frequent gray level ranges, each range consisting of an equal number of pixels. This normalization process is done by first plotting each individual pixel optical density (gray level) that is above an operator set threshold against the number of pixels. This plot is divided into eight equally frequent gray-level ranges (optical density ranges); each range containing an equal number of pixels (FIG. 1A and FIG. 1B). This yields a normalized cell nucleus image consisting of pixels with gray-level values ranging from 0-7.

     As a further step, an 8×8 gray-level transition matrix is constructed from the normalized cell nucleus image by comparing the gray-levels of neighboring picture points (e.g. if a given picture point has a normalized value of 4, and its neighboring picture point has a normalized value of 3, an entry is made in the matrix at location Row-4 and Column-3, and all of the entries at this location are summed). This matrix is then transformed into an 8×8 conditional gray-level transition probability matrix by dividing every matrix entry by the total number of pixels in the cell nucleus image. This &#34;Markovian&#34; probability matrix (Equation 1) is then used to compute the 22 Markovian texture features (Table I). ##EQU1## where each matrix element P L  (i/j) is defined as the conditional probability of gray-level i occurring L picture points after gray-level j occurs, where L is defined as the step size (or size in pixels of the picture point). 
     More recently, JVB Imaging (Elmhurst, Ill.) has written a software application called ILM Morphometry v1.0 that can be applied to listmode files (*.ILM) generated using a CAS-200 Image Analysis System. This program therefore allows the measurement and calculation of the same features as the CMP v3.0 software (Markovian and DNA Content features) as well as eight additional features (listed in Table II). The inventors have already tested this new software on the patient sample reported in this invention and obtained similar statistical model performance as with the CMP v3.0 software.

     In exemplary embodiments of the invention, consideration must be given to several parameters, such as cell selection, magnification, pixel shape and size, camera resolution (number of pixels in the x and y dimension, e.g. number of pixels per μm 2 ), and Markovian step size, which can significantly alter nuclear morphometric descriptor outputs (FIG. 2). The NMD&#39;s have been demonstrated in this invention to be significant independent variables in the prediction of tumor progression and organ confined disease status. As previously indicated, the method for cell selection is critical because of the need to sample biologic tumor heterogeneity. Additionally, the total number of NMD&#39;s required to predict an outcome is decreased as the magnification increases (Table III; also see FIGS. 3-6), as well as significant changes in the individual NMD&#39;s required. The latter is due to an increase in the number of pixels per μm 2  that would enhance the resolution of calculations for the NMD&#39;s. Also notable, the predictive power for all outcomes using the NMD component of the model increases as the magnification increases.

     In other embodiments, either non-parametric statistical methods, or standard or proprietary neural networks were used to validate the utility of NMD&#39;s and biomarkers for the prediction of two possible outcomes, progression and organ confined disease status. Using a clinically and pathologically well-defined retrospective patient sample diagnosed with localized prostate cancer, logistic regression methods were applied on a well defined patient sample (n=124) (Table IV) to determine which NMD&#39;s and biomarkers were capable (e.g. statistically significant) of predicting either progression or organ confined disease status. 
     LOGISTIC REGRESSION PROGRESSION MODEL 
     The invention applies logistic regression to select the univariately significant variables for progression (Table V) using the STATA™ statistical software package (STATA™ command: logistic). Next, these univariately significant variables are multivariately assessed using backwards stepwise logistic regression (STATA™ command: swlogis) to determine which independent variables (e.g. NMD&#39;s (CMP or JVB), Gleason Score, Nuclear Roundness Variance, and biomarkers) are retained to predict progression (Tables VI, Via, VII, and VIIa).

     In another embodiment, the ability of Her-2/neu antigenic expression to identify high risk sub-populations of well to moderately differentiated Gleason grades (2-6) as well as high Gleason grades (≧7) is clearly demonstrated in FIG. 19. Additionally, it was demonstrated that non-diploid DNA ploidy status selected out a subset of well to moderately differentiated Gleason grades (2-6) that were at risk for progression (FIG. 20). 
     LOGISTIC REGRESSION ORGAN CONFINEMENT MODEL 
     This invention also applies logistic regression to select the univariately significant variables for organ confinement (Table VIII) using the STATA™ statistical software package (STATA™ command: loogistic). Next, these univariately significant variables are multivariately assessed using backwards stepwise logistic regression (STATA™ command: swlogis) to determine which independent variables (e.g. NMD&#39;s (CMP or JVB), Gleason Score, Nuclear Roundness Variance, and biomarkers) are retained to predict organ confinement (Tables IX, Ixa, X, and Xa).

     In another embodiment, the ability of PD-41 antigenic expression to identify non-organ confined disease status was evaluated. Positive PD-41 antigenic expression was found in 67 of 95 (71%) patients with non-organ confined disease. Additionally, Her-2/neu antigenic expression was also shown to strongly correlate to non-organ confined disease status. Positive Her-2/neu antigenic expression was found in 80 of 95 (84%) patients with non-organ confined disease. 
     Finally, a select subgroup of patients that developed fatal metastatic disease (n=13) were a evaluated for DNA ploidy, PD-41 and Her-2/neu antigenic expression (Table Xb). DNA aneuploidy was observed in 9 of 13 (69%) and positive PD-41 antigenic expression was found in 9 of 13 (69%) patients that recurred with fatal metastatic disease. Additionally, Her-2/neu antigenic expression was shown to strongly correlate to fatal metastatic disease. Positive Her-2/neu antigenic expression was found in 12 of 13 (92%) patients that recurred with fatal metastatic disease. These data clearly support the potential value of these biomarkers for early identification of patients at high risk for fatal metastatic disease. 
     METHODS TO OBTAIN PATIENT-SPECIFIC RESULTS 
     Logistic Regression Method--STATA™ provides a command (logit, an estimated maximum-likelihood logit model) that provides the weighted coefficients for the statistically significant independent variables used in the multivariate model and the model constant. The general formulas for calculating the predictive index and predictive probability are as follows: 
     Predictive Index (xb)=(β 0  +β 1  var(1)+β 2  var(2)+ - - - +β n  var(n)) 
     Predictive Probability (p)=e xb  /(1+e xb ) 
     Where: 
     β 0  =Formula Constant 
     β 1  through β n  =Weight factors for variables 1 through n 
     var(1) through var(n)=Independent variables being used in logistic regression model. 
     The final calculation of the predictive probability provides a patient-specific value, between 0 and 1, for the probability of a specific outcome (e.g. progression or organ confined disease status). The threshold value (cutoff) for the predicted probability is selected based upon the results of the ROC curves. Table XI illustrates patient specific NMD and multi-parameter (combined) predictive probabilities calculated using this method.

     Neural Networks--The first network configuration to be considered was a standard multilayer sigmoidal network with a single hidden layer. The neural network input layer consisted of either 15, 28, or 30 input nodes to accommodate the input data set of either 15, 28, or 30 measurements (NMD&#39;s and Gleason Score). The activation function in each hidden layer and output layer neuron is sigmoid. Different network configurations (number of hidden layer neurons) with various training termination conditions were tested. FIG. 29 illustrates the neural network configuration used in this study. It was found, for the given training set, that the neural network classifier works best with 20 hidden layer neurons and when the training is terminated at approximately 1000 iterations. 
     The second network configuration tested consisted of a single hidden layer as well. However, the non-linearity function used was the sinusoidal function (proprietary Hybrid network). The output layer neurons still used the sigmoidal transfer function. It had the same structure as the first network (see FIG. 29). A number of different frequencies were tested to find the best combination. The best frequency was found to be F=0.2. 
     All networks (standard and hybrid with 15, 28, or 30 inputs) were tested using the ten different combinations of randomly selected test (18) and training (106) cases. The threshold value (cutoff) used in all cases was 0.5. Table XII summarizes the results using the standard sigmoidal neural networks applied to the n=124 patient sample described in this invention (Tables XIIa, b, &amp; c). Notable is the fact that this network degrades as the number of input features is increased from 15 to 28 to 30. Please note that the 28 and 30 feature networks did not undergo pre-selection using logistic regression methods. The best performing network was the one labeled &#34;15 Input Features&#34;, where the features were pre-selected based upon statistical significance using logistic regression methods. Therefore, the use of statistical methods to pre-select statically significant features improves network performance. Also it is evident from the variation in the predictive rates among the ten trained networks that if the number of patients is increased, the performance of the network should be significantly improved.

     Table XIII illustrates the results for the Hybrid neural network using the n=124 patient sample described in this invention (Tables XIIIa, b, &amp; c). The same observations as made for the standard sigmoidal network above apply to the Hybrid neural network. In conclusion, the use of appropriately trained standard or Hybrid neural networks can be used to predict patient specific outcomes (e.g. progression or organ confined disease status). 
     Classification and Regression Trees (CART)--Application of recursive partitioning methods using the SYSTAT CART™ for DOS v1.02 (Evanston, Ill.) software program was performed. This method is another example of a non-parametric statistical classifier. The use of this method yields similar classification results using the well defined patient sample (n=124), and can generate a patient specific outcome using a trained CART. Those experienced in the art of non-parametric statistical classifiers realize that several other such methods exist and can be applied to achieve this same end.

     DETAILED DESCRIPTION 
     The invention, in its broadest sense, is a method for predicting organ confined disease status or the potential for progression of prostate cancer following radical surgery using either non-parametric statistical analysis methods or neural networks. The parameters assessed by these methods include, but are not limited to, cellular biomarkers and nuclear morphometric descriptors. The invention provides a method to collect nuclear images and extract all relevant shape, size, Markovian texture, and DNA content features important to construction of a mathematical method that gives a single predictive probability for prostate cancer progression or organ localization, with or without pathological grading. The texture features utilized in the present invention are set forth in Table I (CMP v3.0) and Table II (JVB v1.0). It is recognized that in predicting the probability of prostate cancer progression and organ localization, prognostic variable factors other than those listed may be used within the scope and spirit of the present invention. 
     Also embodied in the present invention is the use of a trained neural network to provide a single predictive probability for prostate cancer progression or organ localization given any number of inputs. The multi-layer perceptron network of the present invention is a feed-forward network with one or more hidden layers of neurons between the input and output layers. Using this architecture, many shortcomings of the single layer perceptron are avoided. However, because of the added complexity, the convergence theorem and weight adjustment procedure suggested by Rosenblatt is not applicable. An alternate procedure called &#34;back propagation&#34; has been independently developed by Werbos (Werbos, Ph.D. Thesis, Harvard University, 1974), Parker (Parker, Innovation Report, 581-664, File 1, Office of Technology Licensing, Stanford University, October, 1982), and Rumelhart (see Rumelhart et al., Parallel Distributed Processing Explorations in the Microstructures of Cognition Vol. 1, Foundations, MIT Press, Cambridge, Mass., 1988). This procedure is effective and allows for efficient use of multi-layer perceptrons. But the procedure does not guarantee convergence to the global minima at all times. Also, it requires a large number of training iterations in order to learn a given set of transformations. 
     Because of the problems associated with back propagation, it is of interest to modify the weight adjustment procedure and/or the model developed by Rosenblatt to enable single-layer perceptrons to solve problems such as XOR problems. In this work, a modified perceptron is utilized. The modified perceptron used is a multiple threshold perceptron that is capable of solving XOR problems. This modified perceptron is obtained by changing the non-linearity function. Unlike previous efforts in developing multiple threshold perceptrons, the perceptron of the present invention is capable of handling both binary and analog inputs. The procedure requires fewer number of iterations to develop appropriate input to output transformations when compared to back propagation. 
     For the purposes of this invention, the following clinical and pathological staging criteria is used. The use of other criteria does not depart from the scope and spirit of the invention.

     EXAMPLE I 
     DNA Staining Procedure Using CAS Quantitative DNA Staining Kit (Elmhurst, Ill.; Catalog #102300-01) 
     Preparation of Feulgen Stain Solution: 
     Place 90 ml of Type I H 2  O in a volumetric flask and add 10 ml of 1N HCL. Place a stir bar in a 125 ml Erlenmeyer flask and add the above solution. Add 1 vial of DNA stain reagent to the flask while stirring the solution. Place a rubber stopper in the flask, and stir the contents for at least 1 hour. This Feulgen stain solution should be filtered through a Whatman No. 1 filter immediately before staining of the specimen. 
     Preparation of Feulgen Rinse Solution: 
     Place 285 ml of Type I H 2  O in a 500 ml graduated cylinder and add 15 ml of 1N HCL. Pour this solution into a 500 ml bottle. Immediately before rinsing, place 1 vial of DNA rinse reagent into the bottle and mix the contents by swirling. This solution is stable for 2-3 hours. 
     Preparation of Calibration Slides: 
     To prepare the control cells, place two (2) CAS calibration slides (Elmhurst, Ill.; Catalog #102202-00) in 10% neutral buffered formalin for 30 minutes at room temperature. The calibration slides are touch-prep rat hepatocytes that have a known shape, size, and DNA amount. Next, rinse the CAS calibration slides in running deionized H 2  O for 5 minutes. 
     Preparation of Tissue Samples: 
     The 5 μm formalin fixed, paraffin embedded, tissue sections are first placed on Probe-On™ Plus microscope slides. Place the slides in Hemo-De for 1 minute at 45° C., and then drain the Hemo-De from the slides with the aid of absorbent paper. This step is repeated three (3) more times. 
     Next, place the specimen slides in absolute ethanol for 1 minute at room temperature, and then drain the alcohol from the slides with the aid of absorbent paper. Repeat this step one (1) more time. 
     Finally, place the specimen slides in PBS (pH 7.6) with 0.1% Triton X-100 for 10 seconds at room temperature, and then drain the PBS from the slides with the aid of absorbent paper. Repeat this step one (1) more time. 
     Feulgen Staining Procedure: 
     Place the slides (CAS calibration slides and specimen slides) in 5N HCL for 1 hour at room temperature. Next, place all of the slides in the Feulgen stain solution for 1 hour at room temperature (stir while staining). Drain the Feulgen stain solution and rinse the slides in the Feulgen rinse solution for 30 seconds at room temperature, followed by rinsing the slides in Feulgen rinse solution for 5 minutes at room temperature, followed by rinsing the slides in Feulgen rinse solution for 10 minutes at room temperature. The slides are then rinsed in running deionized H 2  O for 5 minutes. Destaining is done in 1 acid alcohol for 5 minutes at room temperature. This is followed by dipping the slides in 95% ethanol 10 times, followed by dipping the slides in absolute ethanol 10 times, followed by finally dipping the slides in xylene 10 times. Place a cover slip on the slides using a toluene or xylene based mounting media. 
     EXAMPLE II 
     Collection and Processing of CAS-200 CMP v3.0 Nuclear Morphometric Descriptors (40× Objective) 
     The morphometry data from the radical prostatectomy specimens is captured using the Cell Measurement Program v3.0 (CMP v3.0) software from a CAS-200 Image Analysis System. First, a study is set up in CMP v3.0 using the QDA Morphology Mode. The QDA Morphology Mode of CMP v3.0 allows the measurement of the Sum O.D., size, shape, cell class, and the 22 Markovian texture features (a step size of 1 was used in this invention) for each cell (see Table I), as well as the generation of a DNA histogram through the use of the QDA v3.0 software program on the CAS-200 Image Analysis System. Once the study is set up, the CMP v3.0 program (under the QDA Morphology Mode) activates the QDA v3.0 program, and the optical system is calibrated using the CAS calibration slides that were stained with the specimen slides. At least 20 calibration cells are measured, with a calibration peak percent coefficient of variation (% C.v.) of less than 2.0%. (NOTE: If the % C.V. is greater than 2.0%, a problem has occurred in the staining process.) Next, at least 125 cancer cells are analyzed using the method described in Example IV, and the cell nuclear images captured from each 5 μm Feulgen stained tissue section, with all of the sum O.D., size, shape, and Markovian texture measurements being saved to a CMP v3.0 vector (*.VEC) file. The nuclear cell images and DNA content information are saved to a QDA v3.0 listmode (*.ILM) file. The CMP vector file (*.VEC) is then converted to a Lotus 1-2-3 file (*.WK1) using the CMP Exporting Utility (a feature of the CMP v3.0 software). The DNA content information contained in the listmode file is extracted with specially written software and saved to a comma delimited text file. The Lotus 1-2-3 file (*.WK1) is then transferred to a 486 PC equipped with Windows v3.1 and Excel v5.0 for Windows, and an Excel v5.0 macro file is used to convert the Lotus 1-2-3 file (*.WK1) into separate Excel v5.0 files (*.XLS) for each case, each file containing the following information for every cell captured from that particular specimen: the sum O.D, size, shape, cell class, 22 Markovian texture features, and DNA content; (referred to collectively as CMP Nuclear Morphometric Descriptors, or CMP NMD&#39;s). Each Excel v5.0 file (*.XLS) also contains the means, standard deviations, variances, minima, and maxima for each CMP NMD. In addition, the macro creates a summary file containing the above statistics for each sMP NMD from every case. 
     EXAMPLE III 
     Collection and Processing of JVB ILM Morphometry v1.0 Nuclear Morphometric Descriptors 
     The morphometry data from radical prostatectomy specimens is captured from the saved listmode files (*.ILM) using the JVB ILM Morphometry v1.0 software program, which allows the measurement and calculation of up to 36 different features. The listmode files (*.ILM) are created using the QDA v3.0 software from a CAS-200 Image Analysis System. The optical system is calibrated using the CAS calibration slides that were stained with the specimen slides by measuring at least 20 calibration cells, with a calibration peak percent coefficient of variation (% C.V.) of less than 2.0%. (NOTE: If the % C.V. is greater than 2.0%, a problem has occurred in the staining process.) Next, at least 125 cancer cells are analyzed using the method described in Example IV, and the cell nuclear images captured from each 5 μm Feulgen stained tissue section. The DNA content information and cell nuclear images are saved to a listmode (*.ILM) file. The listmode files (*.ILM) are then transferred to a 486 PC equipped with Windows v3.1 and Excel v5.0 for Windows, and converted using the JVB ILM Morphometry v1.0 program into 36 measurements (collectively referred to as JVB Nuclear Morphometric Descriptors, or JVB NMD&#39;s), which are contained in a Microsoft Access Database file (*.MDB). These 36 measurements include the sum O.D., size, shape, DNA content, 22 Markovian texture features, and nuclear shape features (see Table II). The Microsoft Access Database file (*.MDB) is then converted to an ASCII comma delimited file (*.CSV) using a conversion feature of the JVB ILM Morphometry v1.0 program. Finally, using Excel v5.0, an Excel v5.0 macro file is used to convert the ASCII comma delimited file (*.CSV) into separate Excel v5.0 files (*.XLS) for each case, each file containing the JVB NMD&#39;s for every cell captured from that particular specimen. Each Excel v5.0 file (*.XLS) also contains the means, standard deviations, variances, minima, and maxima for each JVB NMD. In addition, the macro creates a summary file containing the above statistics for each JVB NMD from every case. 
     EXAMPLE IV 
     Cancer Cell Selection Method 
     The inventors used a cell selection process for the radical prostatectomy specimens that seemed to introduce the least amount of bias and took into account the heterogeneity of prostate cancer tumors. The tumor area must first be identified by an expert pathologist. Once the tumor area(s) have been identified, a minimum of 25 image fields and a maximum of 5-6 cells per image field must then be analyzed and the cell nuclear images captured. The cells selected may not be overlapping, and they may not contain any &#34;holes&#34;, which is the result of an improper background threshold setting. Sample the entire circled tumor area. The best way to do this is to mentally partition the circled tumor area into four separate quadrants, and then measure a minimum of 6-7 image fields per quadrant. In each quadrant, select image fields from the &#34;worst&#34; (e.g. Highest grade) cancer areas. (NOTE: The &#34;worst&#34; area in each quadrant may vary from low grade, well differentiated cancer to high grade, poorly differentiated cancer. Just be sure to measure from the &#34;worst&#34; area in each of the four quadrants.) Once you have collected the required number of cells, save the DNA information and nuclear images to a listmode file. 
     EXAMPLE V 
     Analysis of CAS-200 DNA Histograms 
     The DNA histograms were interpreted and classified by three different methods by the consensus of five individuals. 
     The three different methods employed cut-offs based upon the results of a DNA Consensus meeting held at Prautz Neck, ME in 1992 (Shankey, T. V. et al. Cytometry 14:497-500, 1993). The histograms were interpreted by four different individuals, and a consensus DNA ploidy classification agreed upon. The classification methods are as follows: (See FIG. 28A and FIG. 28B) 
     DNA-1=(0) Diploid; (1) ONR: Hypodiploid; (2) ONR: &gt;S+G2M (11-21%); (3) Abnormal: &gt;S+G2M (≧21%); (4) Abnormal: Aneuploid; and (5) Abnormal: Tetraploid 
     DNA-IO=(0) Diploid and ONR: Hypodiploid; (1) ONR: &gt;S+G2M (11-21%); (2) Abnormal: &gt;S+G2M (≧21%), Aneuploid, and Tetraploid 
     DNA-10=(0) Normal and Out of Normal Range; (1) Abnormal 
     The three different methods employed cut-offs determined by the inventors. The histograms were interpreted, and the classification methods are as follows: 
     JHHDNA=(0) Diploid; (1) Tetraploid; (2) Aneuploid 
     JHHDNA10=(0) Diploid; (1) Non-Diploid (i.e. Tetraploid and Aneuploid) 
     JHH%&gt;2N=Percentages of S-Phase and Tetraploid fractions combined from ploidy determinations. 
     For statistical analysis, each classification scheme coded every subclass as a result for each patient (i.e. CDI DNA Ploidy: Diploid=0, Hypodiploid=1, ONR: &gt;S+G2M=2, Tetraploid=5, Normal=0, Abnormal=1; JHH DNA Ploidy: Diploid=0, Tetraploid=1, Non-Diploid=1, etc.). The JHH%&gt;2N classification method used the percentage as a result for each patient. These coded results were used for statistical analysis. 
     EXAMPLE VI 
     Nuclear Roundness Factor Measurement and Calculation of Variance 
     Definition of Nuclear Roundness Factor 
     The nuclear roundness factor represents a dimensionless, size-invariant shape descriptor that is based on the ratio of the calculated radius for the measured perimeter divided by the calculated radius for the measured area of the nucleus. This descriptor yields a low value of 1.00 for a perfect circle and increases as the shape of the nucleus deviates from circularity. In mathematical terms: 
     
         Perimeter (P)=2πr.sub.p and Area (A)=πr.sub.a.sup.2 
    
     Solve Equations for the Radius 
     
         (r.sub.p)=(P)/(2π) and (r.sub.a)=√A/π 
    
     Substitute Radius Equations into Nuclear Roundness Factor Equation 
     
         Nuclear Roundness Factor (NRF)=r.sub.p /r.sub.a =((P))(2π))/(√A/π) 
    
     The variance in the nuclear roundness (NRV) was calculated using the following formula: ##EQU2## n=Number of cells measured j=The j th  cell 
     Y j  =The nuclear roundness factor of the j th  cell 
     Y=The average or mean nuclear roundness factor for all of the cells 
     Measurement of Nuclear Roundness using the DynaCELL™ System 
     Histologic tissue sections (5-6 μm) were cut from re-embedded paraffin blocks of radical prostatectomy specimens. Multiple sections were cut (thirty sections per specimen), and one set of slides from each specimen were stained with Hematoxylin and Eosin (Sakura Diversified Stainer, Model DRS-601) and Feulgen stain (Cell Analysis Systems, Elmhurst, Ill.). The H&amp;E staining procedure was performed on sections #1, 10, 20, and 30 for purposes of pathology review to confirm the presence of cancer for additional biomarker studies. All pathologic radical prostatectomy specimens were assigned Gleason scores (sum). The nuclear roundness factor measurements were performed using the H&amp;E sections. A total of 150 cancerous nuclei from the primary tumor were analyzed with a Zeiss inverted IM microscope (Carl Zeiss, Inc., Thornwood, N.Y.) equipped with a Zeiss Planochromatic 100× oil emersion objective, giving a total magnification of 2440×. The nuclear images were digitized and analyzed with the DynaCELL™ Motility Morphometry Measurement workstation (JAW Associates, Inc., Annapolis, Md.). In this invention, the nuclear roundness variance measurement is the only calculation used from the DynaCELL™ Motility Morphometry Measurement software. 
     EXAMPLE VII 
     Utilization of Increased Magnification (63×) to Reduce the Number of NMD&#39;s Required to Predict Progression 
     Using a subset of the original patient sample (10 progressors and 10 non-progressors), measurements were conducted as in Examples II &amp; III, except that instead of using the normal 40× objective, a 63× objective lens was used. The data and statistics obtained using the 63× objective were analyzed and compared to the data and statistics obtained using the 40× objective. Table III summarizes the results of the statistical analysis using the 40× and 63× data to predict prostate cancer progression in the subset of 20 patients. Please note that the total number of NMD&#39;s required to predict an outcome is decreased as the magnification increases (Table III; also see FIGS. 3-6), as well as significant changes in the actual individual NMD&#39;s utilized in the model.

The SuperSensitive MultiLink™ kit (BioGenex Inc., Ca.), which employs the strep-avidin biotin complex (ABC) alkaline phosphatase (AP) labelling method, was used for monoclonal antibody detection. All staining was performed with the MicroProbe™ manual staining system (Fisher Scientific, Pittsburgh, Pa.) that utilizes capillary action vertical staining principles. Incubation for the monoclonal antibody was 4° centigrade overnight. Briefly, the staining procedure includes first preparing the immunostaining reagents as follows:

     The Her-2/neu antigenicity was then scored. The scoring method assessed the amount of staining area within the &#34;dotted cancer zone&#34; as either negative (0), focal (1), or diffuse (2), and the intensity of the staining was scored as 0-4+, ranging from negative (0) to strong red color (4+) resulting from the AP red substrate reaction (see FIG. 28A and FIG. 28B). 
     EXAMPLE IX 
     Immunochemical Staining for PD-41 
     The PD-41 (Prostate Mucin Antigen) monoclonal antibody was provided by Dr. George Wright at Eastern Virginia Medical School under a materials transfer agreement. The SuperSensitive MultiLink™ kit (BioGenex Inc., Ca.), which employs the strep-avidin biotin complex (ABC) alkaline phosphatase (AP) labelling method, was used for monoclonal antibody detection. All staining was performed with the MicroProbe™ manual staining system (Fisher Scientific, Pittsburgh, Pa.) that utilizes capillary action vertical staining principles. Incubation for the monoclonal antibody was 370 centigrade for 15 minutes. Briefly, the staining procedure includes first preparing the immunostaining reagents as in Example X, except with the following changes: 
     Immunostaining Reagent Preparation 
     PD-41 (15 μg/ml) 
     Place 800 μl of PBS pH 7.6 with 0.1% Triton X-100 in a 1.5 ml microcentrifuge tube. Add 100 μl 50 milk to the tube and mix the contents with the aid of a vortex mixer. Then, add 100 μl of PD-41 to the tube and mix the contents with the aid of a vortex mixer. 
     CAS Red Chromogen Solution 
     Add 900 μl of Type I H 2  O to a 1.5 ml microcentrifuge tube. Add the 1 μl of 1 M levamisole to the tube. Then, add 100 μl of CAS red substrate concentrate and mix the contents with the aid of a vortex mixer. Add 45 μl of CAS red chromogen concentrate (always add this ingredient last) to the solution and mix the contents with the aid of a vortex mixer. This solution must be used immediately after preparation. 
     The PD-41 antigenicity was then scored. The scoring method employed the number of positive staining ducts divided by the total number of ducts in the &#34;dotted cancerous zone&#34;. The percentages of positively staining ducts was used as a patient result. 
     PD-41 Background 
     Monoclonal antibody PD-41, a mouse IgG 1k , was first described by Beckett et al. (Beckett, ML, Lipford, GB, Haley, Cl, Schellhammer, PF and Wright, GL. Monoclonal Antibody PD41 Recognizes an Antigen Restricted to Prostate Adenocarcinomas. Cancer Res. 51:1326-1333, 1991) by its reactivity to an prostate adenocarcinoma-restricted mucoprotein known as prostate mucin antigen (PMA). The target PMA, an O-linked oligosaccharide-associated protein with a molecular weight of &gt;400 kd in prostate cancer patient seminal plasma, has not been demonstrated to recognize mucins at other organ sites. Wright et al. (Wright, GL, Beckett, ML et al. Mucins as biomarkers of prostate carcinoma. J. Urol. 149:450A, 1993) demonstrated immunoperoxidase immunoreactivity of PD-41 with in 100% of primary, 71% of metastatic carcinomas and under 1% of normal and benign prostatic tissues, including BPH. 
     An independent study of 95 prostate needle core biopsy paraffin-embedded sections showed PD-41 reactivity in ductal epithelia and/or prostatic glandular secretions within 56% (53/95) of prostate tumor specimens (Marley, GM, Veltri, RW, Patton, KP and Wright, GL. Histochemical Expression of a Unique Prostate Mucin Antigen from Core Biopsies. Proc. Amer. Assoc. Cancer Res. 34:28, 1993). When Gleason score or DNA ploidy were employed as stratification parameters, PD-41 proved to be an independent factor of prognostic value. Clinical follow-ups of 61% of this cohort confirmed that PD-41 expression acted as an independent marker of tumor aggressiveness (Veltri, RW et al., recent CDI unpublished data). 
     EXAMPLE X 
     The Patient Sample 
     A group of one hundred and twenty-four (124) patients with localized prostate cancer were used in this study. The sample was optimized for the evaluation of tumor progression. The patients had clinically localized prostate cancer and were followed for evidence of progression based upon one or more of the following events: a detectable post-operative prostate specific antigen (PSA) level, local recurrence, evidence of metastasis following radical prostatectomy, or death. The patient sample had been clearly defined for pre-operative Gleason grades, post-operative Gleason grades, clinical and pathological stage, organ disease confinement, focal or established capsular penetration, and surgical margin status. None of these patients had any seminal vesicle or lymph node invasion. The demographics of the patient sample is illustrated in Table IV. 
     EXAMPLE XI 
     Statistical Analysis--Logistic Regression 
     The logistic regression statistical analysis of the data was performed using the STATA™ v3.1 (Stata Corporation, College Station, Tex.) statistical analysis software program. This invention applied logistic regression to every independent parameter (e.g. NMD&#39;s, biomarkers, NRV, Gleason scores, etc.) first to select the univariately significant variables for progression or organ confined disease status (Table V &amp; VIII) using the STATA™ statistical software package (STATA™ command: logistic). Statistical significance consisted of p values ≦0.05. Next, the univariately significant independent variables were multivariately assessed using backwards stepwise logistic regression (STATA™ command: swlogis) to determine which independent variables (e.g. NMD&#39;s (CMP or JVB), Gleason Score, Nuclear Roundness Variance, and biomarkers) were aggregately significant in the prediction of progression or organ confined disease status (Tables VI, VIa, VII, VIIa, IX, IXa, X, &amp; Xa). The software program generated Receiver Operator Characteristic (ROC) curves with investigator selected cutoff, resulting in optimized sensitivity, specificity, positive predictive values, and negative predictive values (see above listed tables and FIGS. 7-27). Kaplan-Meier actuary plots were also generated for the progression analysis. 
     STATA™ also provides a command (logit, an estimated maximum-likelihood logit model) that provides the weighted coefficients for the statistically significant independent variables used in the multivariate model as well as the model constant. The general formulas for calculating the predictive index and predictive probability are as follows: 
     Predictive Index (xb)=(β 0  +β 1  var(1)+β 2  var(2)+ - - - +β n  var (n)) 
     Predictive Probability (p)=e xb  /(1+e xb ) 
     Where: 
     β 0  =Formula Constant; 
     β 1  through β n  =Weight factors for variables 1 through n; 
     var(1) through var(n)=Independent variables being used in logistic regression model. 
     The final calculation of the predictive probability provides a patient-specific value, between 0 and 1, for the probability of a specific outcome (e.g. progression or organ confined disease status). The threshold value (cutoff) for the predicted probability is selected based upon the results of the ROC curves. Equation 2 gives an example using the weighted formula. ##EQU3## Predictive Probability: Morphometry P j  =exp(x j  b)/(1+exp(x j  b)), 
     where 
     x j  =The (row) vector of independent variables of the j th  observation, (i.e., the independent variable value). 
     b=The corresponding estimated parameter (column) vector, (i.e., the weight factor associated with that particular independent variable). 
     P j  =Predicted probability of a positive outcome for the j th  observation. 
     EXAMPLE XII 
     Application of Neural Networks 
     The multilayer feed forward perceptron with error back propagation training method is chosen for this work. The back propagation method is a gradient based learning procedure, but has the drawback of local optimum. Studies show sigmoid activation function, which is often used with neural network, is not necessarily the optimal choice. It has been suggested in certain classes of problems that the use of sinusoidal or gaussian activation functions reduce the training time substantially. In this work, both sigmoid and sinusoidal activation functions are studied. 
     In a multilayer neural network, hidden layers are of particular importance. How well the network approximates the discriminate surface to a large degree depends on the number of hidden neurons. Allowing too few or too many parameters to be used in the training will lead to under or over fitting. Therefore, efforts have been made to identify the optimal number of hidden neurons. 
     The neural network (NN) software program of the present invention has a single hidden layer. Morphometry data from the radical prostatectomy samples was analyzed, and a total of 28 NMD&#39;s were extracted. Backwards stepwise logistic regression analysis of the data utilizing the STATA™ software showed that only 14 of the NMD&#39;s were multivariately significant. (NOTE: The 30 feature network used all 28 NMD&#39;s, post operative Gleason score, as well as the perimeter and nuclear roundness variance calculated using the CAS-200). Using the data sets of 15, 28, and 30 measurements, two different network types were trained, a standard multilayer sigmoidal type with a single hidden layer, and a hybrid network previously described. Further utilization of the data used for training these networks within the scope of the invention will result in networks with greater accuracy.
