This conference focuses on the controversies about managing thyroid cancer, emphasizing the possibility that the treatment of patients with potentially fatal thyroid cancer may be improved. Although the mortality rate from thyroid cancer is low, it is the highest among cancers affecting the endocrine glands (excluding the ovary). Exposure to radiation during childhood in the 1930s and 1940s increased the incidence of but not the mortality from thyroid cancer, because these tumors are mainly papillary cancers developing in young adults. These rates may change as the exposed cohort ages. Risk factors that increase mortality include older patient age and the growth characteristics of the tumor at diagnosis, the presence of distant metastases, and cell type (for example, the tall-cell variants of papillary cancer, follicular cancer [to be distinguished from the more benign follicular variant of papillary cancer], medullary cancer, and anaplastic cancer). Local metastases in lymph nodes do not seem to increase the risk for death from papillary cancer, but they do increase the risk for death from follicular and medullary cancer. In the latter, mortality is decreased by the early detection and treatment of patients with the familial multiple endocrine neoplasia syndrome 2a. There are excellent tumor markers for differentiated cancer of the parafollicular and of the follicular cells (serum calcitonin and serum thyroglobulin levels, respectively). Measuring the calcitonin level allows early diagnosis of familial medullary cancer, whereas measuring the thyroglobulin level, although useful only after total thyroidectomy, allows early recognition of recurrence or metastases of papillary or follicular cancer. Initial surgery, protocols for follow-up, and the use of radioiodine for the ablation of any residual thyroid and the treatment of metastatic cancer are discussed. Because these tumors resist currently available chemotherapy regimens, possible ways to increase the effectiveness of radioiodine therapy are considered as are new approaches to treatment.

This relation is sometimes described as a double association: venous thromboembolism (VTE) can reveal cancer (so-called Trousseau syndrome), but cancer and its treatment are also risk factors for VTE. Lung cancer, frequent and serious, is one of the greatest purveyors of VTE, a disease that pneumologists and oncologists must often confront in diagnosis, prevention, and treatment. This article investigates the epidemiological, prevention, and treatment aspects of VTE in cancer patients, particularly those with lung cancer, but also discusses diagnostic specificities and, briefly, the possible antitumor effect of heparins.

Between 2% to 5% of all colon cancers arise in the setting of well-defined inherited syndromes, including Lynch syndrome, familial adenomatous polyposis, MUTYH-associated polyposis, and certain hamartomatous polyposis conditions. Each is associated with a high risk of colon cancer. In addition to the syndromes, up to one-third of colon cancers exhibit increased familial risk, likely related to inheritance. A number of less penetrant, but possibly more frequent susceptibility genes have been identified for this level of inheritance. Clarification of predisposing genes allows for accurate risk assessment and more precise screening approaches. This review examines the colon cancer syndromes, their genetics and management, and also the common familial colon cancers with current genetic advances and screening guidelines.

Imaging techniques play a vital role in the diagnosis, staging, and follow-up of patients who have lung cancer. For this purpose, PET has become an important adjunct to conventional imaging techniques such as chest radiography, CT, ultrasonography, and MR imaging. The ability of PET to differentiate the metabolic properties of tissues allows more accurate assessment of undetermined lung lesions, mediastinal lymph nodes, or extrathoracic abnormalities, tumor response after induction treatment, and detection of disease recurrence.

Studies published in 2013 have addressed the question of whether the rising incidence of differentiated thyroid cancer is actually the result of overdiagnosis. Advances have also been made in the treatment of differentiated thyroid cancer, including improvements in radioiodine therapy.

Sonography plays several important roles in the diagnosis and management of thyroid cancer. Ultrasound (US) is used for the detection and characterization of thyroid nodules as well as a guidance modality for fine-needle aspiration biopsy of indeterminate or suspicious nodules. US is also used to help stage thyroid cancer by identifying cervical lymph nodes suspicious for metastasis so they can be biopsied prior to subsequent neck dissection. Post-thyroidectomy, routine surveillance of the neck is performed with US to identify local recurrence and/or nodal metastatic disease so that focused and limited repeat neck dissection or alcohol ablation can be accomplished.

There are some well known factors involved in the etiology of thyroid cancer, including iodine deficiency, radiation exposure at early ages, or some genetic changes. However, epigenetic modulators that may contribute to development of these tumors and be helpful to for both their diagnosis and treatment have recently been discovered. The currently known changes in DNA methylation, histone modifications, and non-coding RNAs in each type of thyroid carcinoma are reviewed here.

Glucose-regulating protein 78 (GRP78) is a molecular chaperone in the endoplasmic reticulum (ER) that promotes folding and assembly of proteins, controls the quality of proteins, and regulates ER stress signaling through Ca2+ binding to the ER. In tumors, GRP78 is often upregulated, acting as a central stress sensor that senses and adapts to changes in the tumor microenvironment, mediating ER stress of cancer cells under various stimulations of the microenvironment to trigger the folding protein response. Increasing evidence has shown that GRP78 is closely associated with the progression and poor prognosis of lung cancer, and plays an important role in the treatment of lung cancer. Herein, we reviewed for the first time the functions and mechanisms of GRP78 in the pathological processes of lung cancer, including tumorigenesis, apoptosis, autophagy, progression, and drug resistance, giving a comprehensive understanding of the function of GRP78 in lung cancer. In addition, we also discussed the potential role of GRP78 as a prognostic biomarker and therapeutic target for lung cancer, which is conducive to improving the assessment of lung cancer and the development of new therapeutic interventions.

Although physicians enjoy extensive educational backgrounds, financial planning typically is not a significant component of the curricula they have completed. As a result, many physicians could benefit from greater financial acumen, and their preparation for retirement might be lacking in light of their relatively high-income levels. This article by a private wealth advisor with 29 years of industry experience provides physicians with the basic building blocks to understand and manage their finances. It focuses on 3 pillars of financial planning: (1) protecting themselves, their families, and their assets; (2) reducing their taxes; and (3) growing their wealth.

Artificial intelligence is advancing rapidly and making its way into all areas of our lives. This review discusses developments and potential practices regarding the use of artificial intelligence in the field of ophthalmology, and the related topic of medical ethics. Various artificial intelligence applications related to the diagnosis of eye diseases were researched in books, journals, search engines, print and social media. Resources were cross-checked to verify the information. Artificial intelligence algorithms, some of which were approved by the US Food and Drug Administration, have been adopted in the field of ophthalmology, especially in diagnostic studies. Studies are being conducted that prove that artificial intelligence algorithms can be used in the field of ophthalmology, especially in diabetic retinopathy, age-related macular degeneration, and retinopathy of prematurity. Some of these algorithms have come to the approval stage. The current point in artificial intelligence studies shows that this technology has advanced considerably and shows promise for future work. It is believed that artificial intelligence applications will be effective in identifying patients with preventable vision loss and directing them to physicians, especially in developing countries where there are fewer trained professionals and physicians are difficult to reach. When we consider the possibility that some future artificial intelligence systems may be candidates for moral/ethical status, certain ethical issues arise. Questions about moral/ethical status are important in some areas of applied ethics. Although it is accepted that current intelligence systems do not have moral/ethical status, it has yet to be determined what the exact the characteristics that confer moral/ethical status are or will be.

Lung cancer is the leading cause of US cancer-related deaths. Lung cancer screening with a low radiation dose chest computed tomography scan is now standard of care for a high-risk eligible population. It is imperative for clinicians and surgeons to evaluate the trade-offs of benefits and harms, including the identification of many benign lung nodules, overdiagnosis, and complications. Integration of smoking cessation interventions augments the clinical benefits of screening. Screening programs must develop strategies to manage screening-detected findings to minimize potential harms. Further research should focus on how to improve patient selection, minimize harms, and facilitate access to screening.

Lung tumors are one of the most aggressive threats affecting humans. Current therapeutic approaches have improved patients' survival; however, further efforts are required to increase effectiveness and protection against tumor relapse and metastasis. Immunotherapy presents an alternative to previous treatments that focuses on stimulating of the patient's immune system to destroy tumor cells. Viruses can be used as part of the immune therapeutic approach as agents that could selectively infect tumor cells, triggering an immune response against the infection and against the tumor cells. Some viruses have been selected for specifically infecting and destroying cancer cells, activating the immune response, enhancing access, amplifying the cytotoxicity against the tumor cells, and improving the long-term memory that can prevent tumor relapse. Oncolytic virotherapy can then be used as a strategy to target the destruction of transformed cells at the tumor site and act in locations distant from the primary targeted tumor site. Some of the current challenges in lung cancer treatment can be addressed using traditional therapies combined with oncolytic virotherapy. Defining the best combination, including the choice of the right settings will be at the next frontier in lung cancer treatment.

Colorectal cancer is the third most often encountered type of cancer and represents the third leading cause of cancer related deaths, on both sexes. One of the most important prognostic parameters is the tumor's stage at the time of the diagnosis. T4 cancers represent advanced tumors associated with penetration of the visceral peritoneum (T4a) and/or direct invasion in adjacent structures (T4b). Preoperative diagnosis is influenced by the inability of the existent imaging modalities to accurately differentiate the true invasion from the simple, inflammatory adherence to the neighboring structures. As a consequence surgical treatment must follow the principle of en bloc resection; however the ability of achieving an R0 resection depends on the tumor location, invaded organ, and the type of the surgical procedure required. Neoadjuvant treatment for advanced colon cancer it may be very difficult to be applied. This review is focused on preoperative workup, therapeutic strategies and subsequent results in advanced T4 colon cancers.

A hospital-based case-control study on the possible relationship between cholecystectomy and colon cancer is described. In all, 569 cases and 1,129 controls were included in the study. Controls were patients who had been admitted either with another malignant disease (lung cancer or breast cancer), or because of benign gastrointestinal diseases. No differences with regard to colon cancer risk were observed between the two control groups. The crude odds ratio (OR) after cholecystectomy for colon cancer was 2.1 [95% CL (confidence limits) = 1.5; 2.9]. No significant difference in risk between males (OR = 2.0; 95% CL = 1.1; 3.6) and females (OR = 2.1; 95% CL = 1.4; 3.2) was found. A significant inverse relationship was found between the relative risk for colon cancer and sublocalization of the colon cancer, the highest relative risk (RR) found proximal in the colon. A decreasing risk with increasing interval between cholecystectomy and date of diagnosis of colon cancer was found. It is hypothesized that the apparent association between cholecystectomy and colon cancer does not reflect a necessary cause-effect relationship, but is rather an epiphenomenon representing a diminished exposure level to other etiologic factors.

Familial thyroid cancer accounts for 25% of medullary thyroid cancer (MTC) and 5% of non-medullary thyroid cancer. All patients who have familial MTC have one of three variants of multiple endocrine neoplasia type 2 that are defined by specific mutations in the rearranged during transfection (RET) proto-oncogene. Patients who have familial nonmedullary familial thyroid cancer most likely have a mutation that is autosomal dominant with reduced penetrance. Thyroid cancer also is associated with a number of familial syndromes. This article focuses on the genetics and management of familial thyroid cancers and the syndromes associated with thyroid cancer.

Evidence has accumulated showing that an increase in thyroid cancer incidence reflects overdiagnosis of clinically unimportant lesions due to the rise in the use of neck ultrasonography. In the manuscript we examine the hypothesis that the rise in thyroid cancer incidence in Russia is largely caused by overdiagnosis.

While several effects beneficial to health have been attributed to the probiotic lactic acid bacteria, perhaps the most interesting and controversial remains that of anti-cancer activity. The vast majority of studies in this area deal with protective effects against colon cancer. There is no direct experimental evidence for cancer suppression in human subjects as a result of the consumption of probiotic cultures in fermented or unfermented dairy products. However, there is a wealth of indirect evidence, based largely on laboratory studies. Reports in the literature, regarding the anti-cancer effects of lactic acid bacteria, fall into the following categories: in vitro studies, animal studies, epidemiological studies and human dietary intervention studies. Examples of these reports will be given in the present review. The mechanisms by which probiotic bacteria may inhibit colon cancer are still poorly understood. However, several potential mechanisms are being discussed in the literature and these will also be addressed in the present review.

Biomarkers that focus on lung cancer risk assessment, detection, prognosis, diagnosis, and personalized treatment are in various stages of development. This article provides an overview of lung cancer biomarker development, focusing on clinical utility and highlighting 2 unmet clinical needs: selection of high-risk patients for lung cancer screening and differentiation of early lung cancer from benign pulmonary nodules. The authors highlight biomarkers under development and those lung cancer screening and nodule management biomarkers post-clinical validation. Finally, trends in lung cancer biomarker development that may improve accuracy and accelerate implementation in practice are discussed.

Lenvatinib (Lenvima ) is an oral, multi-targeted tyrosine kinase inhibitor (TKI) of vascular endothelial growth factor (VEGF) receptors 1, 2 and 3, fibroblast growth factor receptors 1, 2, 3 and 4, platelet-derived growth factor receptor alpha, and RET and KIT signalling networks, which are implicated in tumour growth and maintenance. In the EU and USA, lenvatinib is indicated for the treatment of locally recurrent or metastatic progressive, radioiodine-refractory differentiated thyroid cancer (RR-DTC). This approval was based on the results of the randomized, double-blind, multinational, phase 3 SELECT study, in which lenvatinib significantly improved median progression-free survival (PFS) and overall response rate compared with placebo in patients with RR-DTC. The PFS benefit with lenvatinib was seen in all pre-specified subgroups, including patients who had received either one or no prior VEGF-targeted therapy. Moreover, the PFS benefit with lenvatinib was maintained regardless of BRAF or RAS mutation status. The safety and tolerability profile of lenvatinib in SELECT was consistent with that of other VEGF/VEGF receptor-targeted therapies and was mostly manageable. Hypertension was the most common treatment-related adverse event in lenvatinib-treated patients, but only infrequently led to discontinuation of the drug. Although not collected in SELECT, information on quality of life would be useful in assessing the overall impact of therapy on the patient. This notwithstanding, the data which are available indicate that lenvatinib is an effective and generally well-tolerated treatment option for patients with RR-DTC. Lenvatinib, therefore, offers an acceptable alternative to sorafenib--currently, the only other TKI approved for this indication.

A 58-year-old man with primary large cell carcinoma of the lung presented with rapidly progressive, bilateral visual loss. The patient was alert and oriented, had no complaints of headache, and was found to have full ocular motility. The optic disks and fundi appeared normal. No visual pathway lesions or other CNS abnormalities were detected on neuro-imaging. The authors discuss their differential diagnosis, clinical diagnostic approach, and subsequent management of this unusual patient.

Localized resection of early stage colon cancer is increasingly technically feasible by truly minimally invasive means. Such techniques as endoscopic submucosal dissection (ESD) and Natural Orifice Transluminal Endoscopic Surgery (N.O.T.E.S.) now raise the prospect of focused intraluminal and transmural resection of small primary tumors without abdominal wall transgression. The potential clinical benefit that patients may accrue from targeted dissection as definitive treatment in place of radical operation is not yet definitively proven but may be considerable at least in the short-term. However, oncological propriety and outcomes must be maintained. In particular methods by which regional nodal staging can be assured if standard operation is avoided need still to be established. Sentinel node mapping is one such putative means of doing so that deserves serious consideration from this perspective as it performs a similar function for breast cancer and melanoma and because there is already considerable evidence to suggest the technique in colonic neoplasia may be at its most accurate in germinal disease. In addition, it may already be employed by laparoscopy while solely transluminal means of its deployment are advancing. While the confluence of operative technologies and techniques now coming on-stream has the potential to precipitate a dramatic shift in the paradigm for the management of early stage colonic neoplasia, considerable confirmatory study is required to ensure that oncology propriety and treatment efficacy is maintained so that patient benefit may be maximized.

In the attempt to build adaptive and intelligent machines, roboticists have looked at neuroscience for more than half a century as a source of inspiration for perception and control. More recently, neuroscientists have resorted to robots for testing hypotheses and validating models of biological nervous systems. Here, we give an overview of the work at the intersection of robotics and neuroscience and highlight the most promising approaches and areas where interactions between the two fields have generated significant new insights. We articulate the work in three sections, invertebrate, vertebrate and primate neuroscience. We argue that robots generate valuable insight into the function of nervous systems, which is intimately linked to behaviour and embodiment, and that brain-inspired algorithms and devices give robots life-like capabilities.

The treatment of differentiated thyroid cancer occurring in children and young adults remains controversial. Because the mortality rate associated with this disease is extremely low and recurrence can develop many years after primary therapy, it is impossible to perform randomized trials that answer therapeutic questions. In previous issues, the topic of thyroid cancer from the surgical perspective has been addressed. Herein the authors discuss the techniques and applicability of radioactive iodine therapy in the treatment of patients with differentiated thyroid cancer. Topics included are indications for treatment as well as short- and long-term complications. A discussion of secondary malignancies is also provided.

BRAFV600E is a constitutively active onco-kinase and is the most common genetic alteration in papillary thyroid carcinoma (PTC), and in anaplastic thyroid carcinoma as well, albeit at a lower frequency. The BRAFV600E mutation in some studies has been significantly associated with extra-thyroidal extension, metastases, recurrence, and mortality in patients with PTC. A recent genome-wide expression profiling approach (Gene Set Enrichment Analysis (GSEA)) and in vitro and in vivo functional studies revealed that BRAFV600E affects extracellular matrix composition (i.e. increased expression of some collagens and laminins) and promotes thyroid cancer migration and invasion. BRAFV600E through the phospho-MEK1/2 and phospho-ERK1/2 pathway may control a network of genes crucial in integrating and regulating the extracellular and intracellular signaling in thyroid cancer cells, which may be fundamental to trigger an abnormal cell differentiation/totipotency and shape/polarity, and contribute to tumor aggressiveness mechanisms (i.e. cell adhesion, migration, and invasion). Increasing our knowledge of BRAFV600E-modulated ECM genes and targeting the subset of genes essential for tumor aggressiveness will help establish a novel paradigm for treatment of thyroid cancers harboring BRAFV600E. Furthermore, identifying downstream events from the BRAFV600E/ERK1/2 pathway will eventually identify novel biomarkers that can be used to correlate with disease outcome and overall survival.
