Colorectal cancer is the second leading cause of death from cancer in the United States. It is third leading cause of cancer death in men behind lung and prostate respectively, and behind lung and breast in cancer deaths among women. More than 130,000 cases are diagnosed each year with over 56,000 of those patients dying. Six percent of the United States population will develop colorectal cancer in their lifetime.

Factors thought to be related to lung cancer include smoking, radon, and educational attainment. These factors were analyzed in the present ecological study for Oregon with correlation and linear regression statistics. A moderate, inverse, and statistically significant correlation was found with educational attainment while surprisingly, negligible and statistically insignificant correlations were found with smoking and radon. More rigorous research such as case-control study designs, are indicated to verify or refute these findings.

Splenic metastasis from lung cancer is a rare clinical event, most often diagnosed at the time of autopsy. We report 2 cases of splenic metastasis with a primary lung cancer. The first case was a 76-year-old man presenting with a recurrent solitary splenic metastasis 14 months after surgical removal of a squamous cell carcinoma of the lung. The second patient was a 72-year-old woman who had a poorly differentiated carcinoma of the lung and multiple abdominal metastasis. We also investigated 267 autopsy cases of lung cancer from 1975 to 1992. Histologically, there were 73 cases of squamous cell carcinoma, 123 adenocarcinoma, 29 large cell carcinoma, 36 small cell carcinoma, and 7 other miscellaneous tumours. The number of splenic metastasis from lung cancer in these cases was 15 (5.6%). Splenic metastasis from a primary cancer of the left lung was more frequent than that from the right lung. Nine of 15 splenic metastases were smaller than 1 cm in size. Splenic metastasis was associated with liver and pancreas metastasis. All 15 autopsy cases with splenic metastasis from lung cancer had other abdominal organ metastasis. Our analysis indicates that a solitary splenic metastasis is rare. Selection of a suitable therapeutic approach is important.

Lung cancer (LC) is a serious public health problem responsible for the majority of cancer deaths and comorbidities in developed countries. Tobacco smoking is considered the main risk factor for LC; however, only a few smokers will be affected by this cancer. Current screening methods are focused on identifying the early stages of this malignancy. Thus, new data concerning the roles of microRNA alterations in inflammation, epithelial-mesenchymal transition and lung disease have increased hope about LC pathogenesis, diagnosis, treatment and prognosis. MicroRNA mechanisms include angiogenesis promotion, cell cycle regulation by modulating cellular proliferation and apoptosis, and migration and invasion inhibition. In this context, this manuscript reviews the current information about many important microRNAs as they relate to the initiation and progression of LC.

Colorectal cancer (CRC) is one of the most prevalent cancers affecting humans, with a complex genetic and environmental aetiology. Unlike cancers with known environmental, heritable, or sex-linked causes, sporadic CRC is hard to foresee and has no molecular biomarkers of risk in clinical use. One in twenty CRC cases presents with an established heritable component. The remaining cases are sporadic and associated with partially obscure genetic, epigenetic, regenerative, microbiological, dietary, and lifestyle factors. To tackle this complexity, we should improve the practice of colonoscopy, which is recommended uniformly beyond a certain age, to include an assessment of biomarkers indicative of individual CRC risk. Ideally, such biomarkers will be causal to the disease and potentially modifiable upon dietary or therapeutic interventions. Multi-omics analysis, including transcriptional, epigenetic as well as metagenomic, and metabolomic profiles, are urgently required to provide data for risk analyses. The aim of this article is to provide a perspective on the multifactorial derailment of homeostasis leading to the initiation of CRC, which may be explored via multi-omics and Gut-on-Chip analysis to identify much-needed predictive biomarkers.

Human thyroid tumors can be derived either from epithelial follicular cells or from parafollicular C-cells. Follicular cell-derived tumors represent a wide spectrum of lesions, ranging from benign adenomas through differentiated (follicular and papillary) and undifferentiated (anaplastic) carcinomas, thus providing a good model for finding a correlation between specific genetic lesions and histologic phenotype. Follicular adenomas and carcinomas show frequently the presence of mutations in one of the three ras genes. Papillary carcinomas show frequently a specific gene rearrangement which gives rise to the formation of several types of so-called RET/PTC chimeric genes. This lesions occur in almost 50% of papillary cancers and consist in the juxtaposition of the 3' or tyrosine kinase domain of the RET gene (which codes for a receptor protein not normally expressed in follicular thyroid cells) with the 5' domain of ubiquitously expressed genes, which provide the promoter and dimerization functions, necessary for the constitutive activation of RET/PTC proteins. Anaplastic carcinomas are frequently associated with mutations of the p53 tumor suppressor. Finally, point mutations of the RET gene are found in familial endocrine syndromes (FMTC; MEN2A and MEN2B), a common feature of which is the medullary thyroid carcinoma, a malignant tumor derived from parafollicular C-cells.

Today, the total knee replacement (TKR) is considered as one of the most successful orthopedics surgeries. The effective long-term pain relief, deformity correction, and restoration of function that it provides have resulted in a large number of these procedures being performed worldwide. It has been observed that 15-20% of patients are not satisfied even after successful TKR surgery. Various attempts such as careful patient selection, pre-operative education, optimization of patients before the surgery, expeditious and precise surgery, aggressive pain control, early return to home, and rehabilitation have been made to improve outcomes and satisfaction among patients. There are also attempts at designing newer implants and introducing smart technology like navigation and Robotics to improve the precision of surgery. In this letter, we look at the pros and cons of the rapid introduction of Robotics in the practice of total knee arthroplasty.

A CpG island DNA methylator phenotype has been postulated to explain silencing of the hMLH1 DNA mismatch repair gene in cancer of the microsatellite mutator phenotype. To evaluate this model, we analyzed methylation in CpG islands from six mutator and suppressor genes, and thirty random genomic sites, in a panel of colorectal cancers. Tumor-specific somatic hypermethylation was a widespread age-dependent process that followed a normal Gaussian distribution. Because there was no discontinuity in methylation rate, our results challenge the methylator phenotype hypothesis and its hypothetical pathological underlying defect. We also show that the mutator phenotype dominates over the gradual accumulation of DNA hypermethylation in determining the genotypic features that govern the phenotypic peculiarities of colon cancer of the mutator pathway.

The incidence of thyroid cancer is increasing worldwide. This is not accompanied by a corresponding increase in mortality. In contrast, in most populations' thyroid cancer mortality has been decreasing in recent decades, although there are some notable exceptions. Relatively few studies focus on mortality and in Latin America we do not find evidence on the temporal trend of mortality. The study of the epidemiology of the thyroid cancer should be approached with a suitable methodology and with data based on the population. Trends should be expressed as an annual percentage of change and/or average annual rate of change. An appropriate method for analyzing trends in thyroid cancer mortality rates is the Joinpoint regression analysis. Previously published findings are described, and the methodology used is compared.

The main targeting structure for theranostics in thyroid cancer is the sodium-iodine symporter (NIS), which has been used in clinical routine for the diagnosis and treatment of thyroid diseases for more than 70 years. Because the different iodine (I) nuclides (123I, 124I, 131I) have the same kinetics, uniquely congruent theranostics are possible in differentiated thyroid cancer. Besides the NIS, there are further possibilities by using expression of somatostatin receptors or the expression of the prostate-specific membrane antigen, for example, in radioiodine-refractory differentiated thyroid cancer, medullary thyroid cancer, or anaplastic thyroid cancer.

Have we made any progress in the treatment of advanced non-small cell lung cancer (NSCLC) over the past 15 years? After hearing the Eastern Cooperative Oncology Group (ECOG) 1594 presented by Dr. Joan Schiller at the plenary session of the 36th Annual Meeting of ASCO, it is hard to be certain. SCHILLER: reported the results of one of the world's largest randomized trials in metastatic lung cancer comparing four platinum-based doublets. There were no differences in survival (primary endpoint) or response between these four regimens, although the cisplatin/gemcitabine arm had a superior time to progression. In her commentary on this study, Dr. Francis Shepherd concluded that progress in the treatment of metastatic lung cancer has occurred at "a snail's pace." Despite the disappointing results of ECOG 1594, there were notable trials describing new agents with novel mechanisms of action reported at this year's ASCO meeting. In small-cell lung cancer, the combination of cisplatin/ irinotecan was found to be superior to cisplatin/etoposide. For NSCLC, novel agents Iressa anti-epidermal growth factor receptor tyrosine kinase and anti-vascular endothelial growth factor monoclonal antibody appear promising.

Thyroid nodules are extremely common in the adult population of the United States, and the incidence of thyroid cancer continues to increase. Preoperative ultrasonography is a crucial component of the work up of thyroid nodules. Recent studies evaluating (18)F-2-fluoro-2-deoxy-D-glucose-positron-emission-tomography, with or without simultaneous computed tomography imaging, are encouraging for its potential utility in thyroid cancer in patients who have an elevated serum thyroglobulin level and a negative (131)I scan.

Lung cancer is the leading cause of cancer deaths for men and women in the United States, accounting for more cancer deaths since 1930 than all other cancer deaths combined. Whereas primary lung cancer was a relatively rare malignancy in the early 1900s, in 1994 there were approximately 170,000 new cases of lung cancer in the United States, of which roughly 100,000 were in men and 70,000 were in women. Despite numerous medical and surgical advances in the past several decades, there has not been a dramatic increase in the percentage of patients being cured of this lethal disease. Smoking is the primary factor responsible for the lung cancer epidemic, but there are numerous other environmental and genetic factors that have been implicated in the pathogenesis of the disease. Recently, it has become evident that passive smoking may also play a significant role in the development of lung cancer. Although screening has not been proven effective in the past, it may be time to reevaluate this technique because early detection of lung cancer affords the best chance for cure.

Lung cancer has been associated with suppression of the cellular immune system. Recent experimental evidence suggests that recognition of HLA class I molecules by cytolytic T lymphocytes is important for tumor resistance. Augmentation of this interaction may soon play a role in cancer therapy.

Thyroid cancer (TC) is a highly heterogeneous endocrine malignancy with an increased incidence in women than in men. Previous studies regarding the pathogenesis of TC focused on the pathological changes of the tumor cells while ignoring the importance of the mesenchymal cells in tumor microenvironment. However, more recently, the stable environment provided by the interaction of thyroid cancer cells with the peri-tumoral stroma has been widely studied. Studies have shown that components of an individual's immune system are closely related to the occurrence, invasion, and metastasis of TC, which may affect response to treatment and prognosis of the patients. This article presents a comprehensive review of the immune cells, secreted soluble mediators and immune checkpoints in the immune microenvironment, mechanisms that promoting TC cells immune evasion and existing immunotherapy strategies. Besides it provides new strategies for TC prognosis prediction and immunotherapy.

Cybersecurity (CS) is a contemporary field for research and applied study of a range of aspects from across multiple disciplines. A cybersecurity expert has an in-depth knowledge of technology but is often also recognized for the ability to view technology in a non-standard way. This paper explores how CS specialists are both a combination of professional computing-based skills and genetically encoded traits. Almost every human behavioral trait is a result of many genome variants in action altogether with environmental factors. The review focuses on contextualizing the behavior genetics aspects in the application of cybersecurity. It reconsiders methods that help to identify aspects of human behavior from the genetic information. And stress is an illustrative factor to start the discussion within the community on what methodology should be used in an ethical way to approach those questions. CS positions are considered stressful due to the complexity of the domain and the social impact it can have in cases of failure. An individual risk profile could be created combining known genome variants linked to a trait of particular behavior using a special biostatistical approach such as a polygenic score. These revised advancements bring challenging possibilities in the applications of human behavior genetics and CS.

The staging of lung cancer is a continuously progressing field, with advances in technology not only improving prognostic accuracy, but fundamentally changing pre-operative investigation algorithms. Noninvasive staging is currently undergoing revolutionary developments with the advent of Positron Emission Tomography, whereas Video-Assisted Thoracic Surgery has already been established as an essential, minimally invasive diagnostic tool for invasive histological staging. Molecular staging may transform future lung cancer staging, promising extremely accurate substaging, and potentially prompting a revision of our anatomically based conceptualization of lung cancer spread. This review presents an appraisal of current lung cancer staging modalities, and presents an overview of recent developments in molecular staging.

Classification of thyroid cancer of follicular origin. The 2017-WHO histological classification individualizes 4 groups of differentiated thyroid cancer of follicular origin: papillary the most frequent with several subtypes, follicular, oncocytic and poorly differentiated. This histological classification is closely related to genomic abnormalities found in these cancers. Initial estimate of the risk of cancer related death is based on the TNM classification and that of the risk of recurrence on the American Thyroid Association stratification; these two risk estimates will guide the extent of initial treatment. Then, a dynamic classification that can be modified at each work-up will appreciate the tumoral status and thus the risk of recurrence and of cancer related death.

For centuries, designers and engineers have looked to biology for inspiration. Biologically inspired robots are just one example of the application of knowledge of the natural world to engineering problems. However, recent work by biologists and interdisciplinary teams have flipped this approach, using robots and physical models to set the course for experiments on biological systems and to generate new hypotheses for biological research. We call this approach robotics-inspired biology; it involves performing experiments on robotic systems aimed at the discovery of new biological phenomena or generation of new hypotheses about how organisms function that can then be tested on living organisms. This new and exciting direction has emerged from the extensive use of physical models by biologists and is already making significant advances in the areas of biomechanics, locomotion, neuromechanics and sensorimotor control. Here, we provide an introduction and overview of robotics-inspired biology, describe two case studies and suggest several directions for the future of this exciting new research area.

Papillary thyroid cancer is predominantly a sporadic disease that usually presents as an asymptomatic thyroid mass in a euthyroid patient. Irradiation to the neck during childhood significantly increases the subsequent risk of this cancer; the prognosis for radiation-related cancers is similar to spontaneous cases. Physical examination, thyroid scanning and ultrasound, and fine-needle aspiration are used to differentiate between benign lesions and papillary thyroid cancer. Near-total thyroidectomy with postoperative radioiodine ablation is currently advocated for most patients, and has excellent results with regard to survival. In children, papillary thyroid cancer often presents with extensive regional disease as well as diffuse lung metastases. Surgery and radioiodine are very effective in such cases, and survival remains excellent. As late recurrences may occur, patients require regular long-term follow-up regardless of the extent of initial disease.

There is no evidence that natural radiation (cosmic radiation or from natural radioiosotopes) increases the risk for thyroid diseases. Moreover, while it has been proven that exposure to external medical radiation or to external and internal radiation by atomic bomb explosions leads to an increased risk for thyroid cancer, the medical use of radioiodine, namely diagnostic and therapeutic application of (1)(3)(1)I, is safe and does not induce thyroid cancer. Exposure of children aged less than 4 years to fallout from the Chernobyl reactor accident has led to a substantial increase of childhood cancer incidence in the countries affected (Belarus, Ukraine and Western parts of Russia). Up to now, the total number of cases in children and adolescents adds up to approximately 5,000; in the next 50 years, approximately 15,000 additional thyroid cancer cases in this age group are expected. With respect to the Chernobyl effects on adults, there is no proven radiation related increase of the thyroid cancer incidence. As can be proven by a therapy project in 247 children with advanced thyroid cancer from Belarus, the prognosis for this tumor, even when metastasized, is good, this being in accordance with literature data indicating mortality rates between 1 and 2%.

The past decade has seen an enormous advancement in the therapy for lung cancer, predominantly seen in adenocarcinoma, ranging from the introduction of histology-based drugs to the discovery of targetable mutations. These events have led to a personalized therapeutic approach with the delivery of drugs that target specific oncogenic pathways active in a given tumor with the intent of acquiring the best response rate. The discovery of sensitizing mutation in the epidermal growth factor receptor gene as the basis for clinical response to tyrosine kinase inhibitors led to a systematic search for other molecular targets in lung cancer. Currently, there are several molecular alterations that can be targeted by experimental drugs. These new discoveries would not be possible without a parallel technological evolution in diagnostic molecular pathology. Next-generation sequencing (NGS) is a technology that allows for the evaluation of multiple molecular alterations in the same sample using a small amount of tissue. Selective evaluation of targeted cancer genes, instead of whole-genome evaluation, is the approach that is best suited to enter clinical practice. This technology allows for the detection of most molecular alteration with a single test, thus saving tissue for future discoveries. The use of NGS is expected to increase and gain importance in clinical and experimental approaches, since it can be used as a diagnostic tool as well as for new discoveries. The technique may also help us elucidate the interplay of several genes and their alteration in the mechanism of drug response and resistance.
