Hickman‐broviac catheter use in cancer patients
Authors: Landoy Zvi , Rotstein Coleman , Lucey Joyce , Fitzpatrick John 
Published: February 2007

AbstractSeventy‐nine patients who had Hickman‐Broviac (H‐B) catheters inserted over a 1‐year period were studied. There were 52 patients in the hematological group and 27 patients in the solid tumor group. Complications associated with the H‐B cathethers were infection and venous thrombosis, with infection being more common. Nine patients experienced local infection, ten had local infection with bacteremia, and 14 had severe infection, respectively. Infectious complications were more prevalent in the hematological group; 13 of the 14 severe infections were found in patients with hematological disorders. Severe infection was more common in patients with two catheters in place as compared to those with only one catheter (P < 0.05). In particular, the presence of two catheters significantly increased the risk of infection in hematological patients. The risk of infection may be reduced by using only one catheter with either a single or double lumen.
Duodenojejunostomy and stapled occlusion for distal duodenal perforation from malignant retroperitoneal tumors
Authors: Kostroff Karen M. , Turnbull Alan D. , Rotstein Lorne E. , Raaf John H. 
Published: February 2007

AbstractThree patients with unresectable malignant retroperitoneal tumors that invaded and perforated the distal duodenum presented with sepsis unresponsive to antibiotics. A technique of proximal side‐to‐side duodenojejunostomy with stapled occlusion of the distal duodenum resulted in successful diversion and immediate resolution of sepsis.
Comparision of immunologic and enzymatic assay of prostatic acid phosphatase for follow‐up and assessment of clinical status of stage d prostate cancer

Published: February 2007

AbstractProstatic acid phosphatase (PAP) was measured in 70 patients with stage D prostate cancer under different modalities of treatment. PAP was determined by radioimmunoassay (RIA), counter immunoelectrophoresis (CIEP), and enzymatic method using α‐naphthyl phosphate to compare the usefulness of the three methods in follow‐up and assessing the clinical status of stage D prostate cancer. In the regressive state (29 patients), RIA and enzymatic methods correlated well; both gave 17% of abnormal results with a mean value of 4.7 ± 4.6 and 3 ± 1.7. Also, in the progressive state (17 patients) the two methods showed similar percentages of abnormal results with a mean value of 40 ± 38 and 19 ± 17 for RIA and enzymatic method, respectively. There was greater variability in the stable group owing to the difference in the tumour load. Again the two methods correlated well regarding their diagnostic sensitivity and specificity as a parameter for assessing the clinical response. CIEP, used as a qualitative method, showed more positive than negative results and did not correlate with the clinical state. We feel that the conventional enzymatic method is adequate for follow‐up and assessing clinical state of stage D prostate cancer.
Six recent liposarcomas including largest to date
Authors: Takagi Hiroshi , Kato Kimiyuki , Yamada Eikichi , Suchi Taizan 
Published: February 2007

AbstractThis report describes six cases of liposarcoma. The primary sites were the retroperitoneum in three cases, the lower extremity in two cases and the jejunal mesenterium in one case. One retroperitoneum case had the heaviest liposarcoma (40 kg) that has been reported in the literature. One patient with thigh liposarcoma who developed three recurrences and underwent hemipelvectomy has been free from the disease for the past 6 1/2 years. Histologically, all three retroperitoneum cases showed well‐differentiated liposarcoma and two lower extremity cases had myxoid type liposarcoma.
Tracheal carcinoma presenting as a thyroid tumor
Authors: Zirkin Howard J. , Tovi Ferit 
Published: February 2007

AbstractDirect invasion of the trachea by an aggressive tumor originating in the thyroid gland is an unusual but well‐documented phenomenon. The reverse situation, that is, a primary tracheal neoplasm invading by direct extension into the thyroid gland and presenting as a thyroid mass is apparently an even less common occurrence. A careful search of the literature has failed to reveal any recorded instances of this type of occurrence. We report a case of an adenoid cystic carcinoma arising in the trachea and invading the thyroid gland and recurrent laryngeal nerves causing vocal cord paralysis. The presentation of this lesion as a primary thyroid tumor is an unusual occurrence that serves to remind the clinician that in the differential diagnosis of thyroid masses one must include the possibilities of metastases or direct extension of a primary neoplasm from another organ.
Lateral pectoralis nerve: The need to preserve it in the modified radical mastectomy
Authors: Serra G. Elpidio , Maccarone G. Biagio , Ibarra P. Eduardo , de la Fuente Rafael 
Published: February 2007

AbstractThe preservation of the medial pectoralis nerve is classical and compulsory in the Patey Modified Radical Mastectomy, which innervates the clavicular and sternal insertions of the pectoralis major muscle. The lateral pectoralis nerve innervates the lower third, and the costo‐abdominal insertions of the pectoralis major muscle.The tight relationship of this nerve with the pectoralis minor muscle makes it impossible to resect the muscle without damaging the nerve. The lesion of this nerve causes fibrosis, atrophy and shortening of the pectoralis major muscle, limitations of the shoulder movements, and a certain degree of skeletonization of the chest wall. Routine removal of the pectoralis minor muscle, as seen in Patey's type operation, with sectioning of the lateral pectoralis nerve, and the above mentioned sequela, is not recommended since it destroys the cosmetic result which is the main objective of the surgery. In naming these structures we prefer Moosman's proposal, because it is easier to remember, it adapts better to our surgical training, and it denotes course location and distribution. We encourage the preservation of the pectoralis minor muscle, and the lateral pectoralis nerve in the modified radical mastectomy, following the Scanlon's proposal in the hope of maintaining a cosmetic aspect and an appropriate base for the reconstructive surgery.
Biliary and duodenal bypass for carcinoma of the head of the pancreas
Authors: Gough Ian R. , Mumme Geoffrey 
Published: February 2007

AbstractA review was undertaken of 66 patients having palliative bypass surgery for carcinoma of the head of the pancreas. A second laparotomy for relief of duodenal obstruction was necessary in six of 29 (20%) of the patients who did not have gastroenterostomy performed initially, but late gastric outlet obstruction occurred only once in 37 patients having an initial gastroenterostomy (P < 0.05). Cholecystojejunostomy failed to provide permanent biliary bypass in 14 of 53 (26%) patients, compared to successful drainage in all 13 patients having anastomosis of the common hepatic duct to the jejunum (P < 0.05). In seven patients cholecystojejunostomy was performed when the cystic duct was already obstructed by tumour. Therefore prophylactic gastrojejunostomy is recommended as a routine. The gallbladder should only be used for biliary bypass when appropriate contrast x‐rays have demonstrated the patency of the cystic duct.
Primary carcinoma of stensen's duct: Recognition and management with literature review
Authors: Frechette Claude N. , Demetris Anthony J. , Barnes E. Leon , Futrell J. William 
Published: February 2007

AbstractPrimary carcinoma of Stensen's duct is a rare neoplasm with only 15 cases reported in the English literature since 1927. The authors present a recent additional patient and discuss their criteria for the determination of true primary ductal lesions based upon clinical presentation, operative findings, and tumor histology. This method of selection, most particularly involving electron microscopy in the reported case, is necessary to define whether the lesion originates from the ductal epithelium. All previously reported cases were reviewed, together with the actual pathologic slides in four available cases. Only ten were retained as primary ductal lesions. Most important, this analysis clarifies the natural history of these neoplasms and reinforces a recent theory of histogenesis of salivary gland tumors. In light of these findings, a rational treatment plan can be suggested.

Published: February 2007

AbstractSolitary muscle tumor, representing the first manifestation of metastatic renal cell carcinoma, is rare. A case report of a tumor mass in the left posteromedial arm, which proved to be metastatic from the right kidney, is presented. The incidence of this condition among patients presenting as a soft tissue sarcoma may be about 1%.
Primary neuroendocrine carcinoma of the skin (Merke's cell carcinoma)
Authors: Alexiou G. , Papadopoulou‐Alexiou M. , Karakousis C. P. 
Published: February 2007

AbstractPrimary neuroendocrine carcinoma of the skin (Merkel's cell carcinoma) is a rare tumor. Until recently 86 patients with this tumor have been described. Two cases of this tumor are presented. This neoplasm has a high propensity for lymphatic as well as hematogenous metastases. It presents as a dermal or subcutaneous nodule. Awareness of this condition may lead to earlier diagnosis and improved survival.
Carcinosarcoma of the heart
Authors: Chen Karl T. K. 
Published: February 2007

AbstractA unique intracardiac tumor arising in the left atrial wall is described. The patient presented with the classical clinical features of left atrial myxoma. The resected tumor was histologically malignant and showed features of a carcinosarcoma, a tumor type which has not previously been reported to arise in the heart. Histogenetically, this tumor may represent the malignant counterpart of cardiac myxoma.

Published: February 2007

AbstractTwenty‐seven patients with paranasal sinus carcinoma were analyzed. Local control with radiation alone was poor, with most patients failing centrally within the primary site. With preoperative radiation local control is 60%. Previous reports have emphasized failure at superior sites—particularly the orbit. The pattern of local failure in our series is predominantly various medial sites inclusive of intact or exenterated orbit. The surgically nonremovable medial structures are best encompassed by a three‐field radiotherapy technique (weighted anterior and two laterals).

Scrotal calcinosis: Calcification of epidermal cysts
Authors: Sarma Deba P. , Weilbaecher Thomas G. 
Published: February 2007

AbstractThe so‐called idiopathic scrotal calcinosis does not appear to be idiopathic, but rather a process of dystrophic calcification of epidermal cysts. We report a case that would be otherwise called “idiopathic” where we found squamous epithelial lining around the calcified masses. Literature is reviewed in support of the view that the calcified scrotal nodules are related to epidermal cysts.
Chemotherapy trials in malignant pheochromocytoma: Report of two patients and review of the literature

Published: February 2007

AbstractTwo patients with metastatic pheochromocytoma received chemotherapy with 5‐fluorouracil, cyclophosphamide, and streptozotocin. A biochemical response occurred in one instance. A review of the literature and the results in the reported patients indicate cyclophosphamide and/or streptozotocin may have activity in this neoplasm.

Published: February 2007

AbstractA 39‐year‐old black woman noted a pigmented lesion on her right buccal mucosa of which she had been previously unaware. Physical examination revealed a 2.0 × 1.8‐cm uniformly pigmented, macular to slightly plaque‐like, symmetrically folded, indented lesion. Histologic examination revealed a hyperplastic mucous membrane containing numerous dendritic melanocytes at all levels. No pleomorphism or cytological atypia was recognized and no fibrosis was present in the corium. The case was diagnosed as “melanoacanthoma”.

Published: February 2007

AbstractBoth basal cell carcinomas that arise in blacks and those that metastasize are rare, and development of this tumor is an uncommon, late complication of trauma. We report a case of a 70‐year‐old black man with a basal cell carcinoma arising in a gunshot wound in a shoulder and metastasizing to axillary lymph nodes. Histologically, the tumor was of the metatypical type.
Peroxidase antiperoxidase versus specific red cell adherence in detection of O (H) antigen in bladder cancer: A blind study
Authors: Javadpour N. , Vafrier J. , Worsham G. F. , O'connel K. 
Published: February 2007

AbstractWe have previously demonstrated that the presence or absence of ABO(H) cell surface antigens correlated with stage, grade, and prognosis of patients with bladder cancer. However, because of the weak antigenecity of 0(H), certain investigators have reported a high rate of false‐negative results utilizing specific red cell adherence (SRCA) test of Davidsohn. Since approximately 45% of the population is blood group 0(H), this high rate of false‐negative result renders the test unreliable in an ordinary laboratory. The present study is comparing the results of SRCA to that of peroxidase antiperoxidase (PAP) technique in a double‐blind fashion in 29 patients with bladder cancer having 0(H) blood group. In terms of grade, stage, frequency of recurrent tumor, and quality of slides, the results of PAP is superior over SRCA. Furthermore, the convenience, permanence, and ready availability of PAP will enhance the utility of this test in a conventional histopathologic laboratory with a high rate of accuracy and reproducibility.

Published: February 2007

AbstractThis report reviews the results of treatment of hepatic malignancies by intra‐arterial infusional chemotherapy and hepatic artery ligation. Seventy‐nine patients with liver metastases or primary hepatomas were treated by this technique between the years 1970 and 1982. The majority of patients had metastatic disease from colon and rectal cancers. The median and mean survivals in the total group was 10 and 14 months, respectively (including operative deaths). Patients with metastatic disease from colon and rectal cancers had better survival than those with metastases from other primaries. Patients with synchronous liver malignancy had better survival than those with metachronous disease. Length of survival correlated positively with the duration of chemotherapeutic infusions, the latter being frequently (in 42% of patients) interrupted because of catheter complications. A new technique utilizing implantable pumps can be expected to further improve the results by reducing catheter malfunction and prolonging treatment courses.
A technique for isolated hyperthermic liver perfusion
Authors: Quebbeman Edward J. , Skibba Joseph L. , Petroff Robert J. 
Published: February 2007

AbstractHyperthermia, either alone or combined with chemotherapy, has been shown to be effective in treating cancer. Because some investigators believe that regional hyperthermia may be more effective than whole body hyperthermia, we developed a technique to heat only the liver to 42‐43 degrees for 4 hr. The procedure was adapted from a previously described animal model and was performed in four humans. Vascular isolation of the liver was accomplished by cannulating the hepatic artery, the portal vein, and the inferior vena cava followed by occluding the suprahepatic vena cava and the liver was then perfused with blood and nutrients from an oxygenated reservoir. Preliminary results show radiologic and histologic evidence of tumor necrosis or cessation of tumor growth in three of the patients. We believe this technique is safe enough for clinical experimental use and deserves further investigation.

Published: February 2007

AbstractWe report a patient with a large apocrine hidrocystoma. These tumors are almost always under 10 mm in diameter. In this 40‐year‐old man the tumor measured 20 mm. Apocrine hidrocystoma must be considered when evaluating a patient with a large cystic lesion of the face. Surgical management is similar to that of other benign cystic lesions of this region.
Evaluation of leukocyte adherence inhibition (LAI) test in primary and secondary hepatic malignancies
Authors: Tantry B. V. , Jain A. K. , Gupta Saroj , Gupta J. P. 
Published: February 2007

AbstractLeukocyte adherence inhibition (LAI) has been demonstrated to be a simple, rapid, and reliable technique in the diagnosis of various malignancies including hepatocellular carcinoma. The LAI test was carried out employing modified tube LAI technique in patients with primary hepatocellular carcinoma (HCC) and secondary carcinomas of liver. Positive LAI response to HCC antigen was obtained in all six (100%) cases of hepatocellular carcinoma tested. None of the control cases, which included 8 healthy subjects and 16 cases of benign liver diseases, gave positive LAI response. Two out of 19 cases of secondary carcinoma gave a positive LAI reaction to HCC antigen. In secondary carcinomas, 19 out of 21 cases (90.48%) gave positive LAI reaction to secondary adenocarcinoma antigen. There were two false positives in controls (1 each of cirrhosis and amebic liver abscess), and 1 out of 8 cases of HCC also gave positive response to secondary carcinoma antigen. Thus, LAI test was found to be useful in the diagnosis of hepatic malignancies.

Published: February 2007

AbstractFrom 1961 to 1980 17 patients with nasopharyngeal carcinoma who were less than 30 years old at time of diagnosis were treated at the two oncologic hospitals in Puerto Rico. Fourteen of the tumors were lymphoepitheliomas and the remaining three were anaplastic carcinomas. Ninety‐four percent of the patients were found to have neck adenopathy at the initial examination and in 65% of them the adenopathy was bilateral. The 5‐year actuarial survival was 14. The main cause of failure was the distant metastasis. Seventy‐one percent of our patients developed distant metastasis sometime during the course of their disease.Carcinoma of the nasopharynx is uncommon in Puerto Rico as in other western countries. The post‐adolescent age incidence peak reported from different countries is also present among Puerto Ricans.

Published: February 2007

AbstractA case of double carcinoma of the colon is presented in association with subacute bacterial endocarditis due to Streptococcus bovis. The presence of Streptococcus bovis septicemia is a strong pointer in favour of associated colon carcinoma even in the absence of gastrointestinal symptomatology.
A new tumor imaging agent‐111In‐bleomycin complex. Comparison with 67Ga‐citrate and 57Co‐Bleomycin in tumor‐bearing animals
Authors: Hou De‐Yan , Hoch Hans , Johnston Gerald S. , Tsou K. C. , Jones Alfred E. , Miller Elizabeth E. , Larson Steven M. 
Published: February 2007

AbstractWe have found a new 111In‐bleomycin complex (BLMC), which has high affinity to tumor, does not bind to transferrin and is stable in vivo. Distribution in animals bearing glioma, hepatoma, or mammary adenocarcinoma at 48 hours showed: the ratios of tumor to blood, brain, heart, lung, liver, pancreas, stomach, and femur were 1.4‐22.4 times as high for 111In‐BLMC as for 67Ga‐citrate. In mammary adenocarcinoma, 111In‐BLMC bound more to viable and 57Co‐Bleomcyin (BLM) more to necrotic tumor. In viable tumor, the concentration of 111In‐BLMC was similar to that of 57Co‐BLM. The ratios of tumor to stomach and pancreas were higher, to blood, brain, muscle, heart, and femur were lower for 111In‐BLMC than those for 57Co‐BLM. The ratios of tumor to lung, liver, spleen, skin, and kidney were similar for the two compounds. Tumors were imaged more distinctly with the new 111In‐BLMC and 57Co‐BLM than with 67Ga‐citrate. 111In‐BLMC is promising for tumor imaging.
Colocutaneous fistula complicating tenckhoff catheter placement for intraperitoneal chemotherapy

Published: February 2007

AbstractIn view of the characteristic intra‐abdominal spread of carcinoma of the colon and rectum [1‐3], the use of intraperitoneal chemotherapy may offer an alternative to intravenous or oral drug therapy and even radiation therapy for recurrent disease [4,5]. Several investigators have demonstrated that intraperitoneal drug administration may result in portal vein levels ten to 20 times higher than those observed in peripheral venous blood samples [6]. Traditionally, intraperitoneal chemotherapy has been administered through the Tenckhoff catheter system which was originally developed for peritoneal dialysis in patients with acute or chronic renal failure [7,8]. We report a case of Tenckhoff catheter erosion into the colon with subsequent fistulization developing 20 days after intra‐operative placement for intraperitoneal or “belly bath” chemotherapy; this complication occurred in a patient with locally recurrent colorectal adenocarcinoma in whom pelvic peritoneal implants without hepatic metastases were identifed at reoperation. This complication of the Tenckhoff catheter system has not previously been reported in the surgical literature.
