BACKGROUND: The thyroid cancer incidence rate has tripled in the United States since the 1980s, especially among women and small-sized tumors. This trend has been attributed to increased detection due to the availability of ultrasound and fine-needle aspiration technology. In 2009, the American Thyroid Association (ATA) released revisions to their guidelines for well-differentiated thyroid cancers. OBJECTIVE: To examine trends in thyroid cancer incidence rates by tumor size and gender following the 2009 ATA guideline revisions...

Epidemiological studies suggest that soya consumption as a source of phyto-oestrogens and isoflavones may be associated with a reduced risk of colorectal cancer. However, findings have not yet been synthesised for all groups of phyto-oestrogens. A meta-analysis was conducted to quantify the association between phyto-oestrogens and colorectal cancer risk. Relevant observational studies published up to June 2016 were identified by searching MEDLINE, EMBASE and Cochrane Library databases. Study-specific relative risks (RR) were pooled in both categorical and dose-response meta-analyses...

Cervical cancer is the second most frequent cancer in women in French Guiana. Studies have shown that populations living in the remote areas of the interior have early sexual debut and that multiple sexual partnerships are common. The objective of the present study was thus to determine the prevalence of human papillomavirus (HPV) infection in these areas. A study was conducted in women aged 20-65 years with previous sexual activity. Women were included on a voluntary basis after using local media and leaders to inform them of the visit of the team...

Evolutionary theory explains why metazoan species are largely protected against the negative fitness effects of cancers. Nevertheless, cancer is often observed at high incidence across a range of species. Although there are many challenges to quantifying cancer epidemiology and assessing its causes, we claim that most modern-day cancer in animals - and humans in particular - are due to environments deviating from central tendencies of distributions that have prevailed during cancer resistance evolution. Such novel environmental conditions may be natural and/or of anthropogenic origin, and may interface with cancer risk in numerous ways, broadly classifiable as those: increasing organism body size and/or life span, disrupting processes within the organism, and affecting germline...

RATIONALE: The highest burden of liver cancer occurs in developing countries, where the use of herbal medicine (HM) is still widespread. Despite this trend, few studies have been conducted to report HM practices of patients with a hepatic tumor in the developing world. Hence, this study aimed to document the use of HM among patients with liver cancer in Peru. STUDY DESIGN AND METHODS: A comparative behavioral epidemiological survey was conducted among liver cancer patients attending the National Cancer Institute of Peru...

REVIEW
Yi-Chia Lee, Jaw-Town Lin
Helicobacter pylori infection is the major cause of gastric cancer, and removal of H. pylori infection from a population could theoretically decrease the number of cases by about 89%. However, in real-life settings, few studies have reported the effect of screening and treating this pathogen in population-based programs. This is mainly because of the lack of an adequate infrastructure for delivery of systematic screening services to asymptomatic individuals, the lack of standardization to ensure that each subject receives the correct diagnostic testing and antibiotic treatment, and limited resources...

REVIEW
Dede N Ekoue, Chenxia He, Alan M Diamond, Marcelo G Bonini
Reactive oxygen species (ROS) largely originating in the mitochondria play essential roles in the metabolic and (epi)genetic reprogramming of cancer cell evolution towards more aggressive phenotypes. Recent studies have indicated that the activity of superoxide dismutase (SOD2) may promote tumor progression by serving as a source of hydrogen peroxide (H2O2). H2O2 is a form of ROS that is particularly active as a redox agent affecting cell signaling due to its ability to freely diffuse out of the mitochondria and alter redox active amino acid residues on regulatory proteins...

BACKGROUND: Despite its impact on female health worldwide, no efforts have been made to depict the global architecture of ovarian cancer research and to understand the trends in the related literature. Hence, it was the objective of this study to assess the global scientific performance chronologically, geographically and in regards to economic benchmarks using bibliometric tools and density equalizing map projections. METHODS: The NewQIS platform was employed to identify all ovarian cancer related articles published in the Web of Science since 1900...

BACKGROUND: A breast cancer (BC) diagnosis can profoundly affect the sex life of patient and partner within a couple. The purpose of the present study is to examine whether individual and partner sexual functioning, affectionate behavior, emotional closeness and depressive symptoms are associated with change over time in satisfaction with sex life of sexually active heterosexual couples dealing with BC and to explore whether the associations differ between patients and partners after adjustment for basic sociodemographic characteristics, comorbidity and BC treatment...

Some epidemiological studies suggest an association between genital use of talc powders and increased risk of ovarian cancer, but the evidence is not consistent. We performed a meta-analysis of epidemiological studies to formally evaluate this suspected association. A systematic search was conducted in Medline, Embase, and Scopus, leading to the identification of 24 case-control studies and three cohort studies, including 302 705 women with ovarian cancer. In the meta-analysis, we used a random-effect model to calculate summary estimates of the association between genital use of talc and occurrence of ovarian cancer...

Phytoestrogens derived from plants exert estrogenic as well as antiestrogenic effects and multiple actions within breast cancer cells. Chemopreventive properties of phytoestrogens have emerged from epidemiological observations. In recent clinical research studies, phytoestrogens are safe and may even protect against breast cancer. In this brief review, the molecular mechanisms of phytoestrogens on regulation of cell cycle, apoptosis, estrogen receptors, cell signaling pathways, and epigenetic modulations in relation to breast cancer are discussed...

Colorectal cancer (CRC) is a malignant disease whose incidence and mortality rates are greatly influenced by environmental factors. Under-treatment of CRC such as a poor diagnostic evaluation, less aggressive surgery, less intensive chemotherapy results in metastasizing of the primary tumor cells and recurrence of cancer. Prolonged chemotherapy treatment against cancer is hazardous to the patients, which also limits its use in cancer therapy. Current research in developing a novel anti-cancer agent, direct towards finding a better anti-metastatic and an anti-invasive drug with reduced side effects...

Although genes contribute to colorectal cancer, the gut microbiota are an important player. Accumulating evidence suggests that chronic infection and the ensuing inflammation contributes to tumor initiation and tumor progression. A variety of bacterial species and tumor-promoting virulence mechanisms have been investigated. Significant advances have been made in understanding the composition and functional capabilities of the gut microbiota and its roles in cancer. In the current review, we discuss the novel roles of microbiota in the progression of colon cancer...

Epidemiologic studies indicate the use of either statins or aspirin have beneficial effects in prostate cancer patients. The present study was undertaken to evaluate the effects and mechanisms of atorvastatin and aspirin alone or in combination in human prostate cancer cells cultured in vitro and grown as xenograft tumors in severe combined immune-deficient (SCID) mice. The growth and apoptosis in prostate cancer cells were determined by the trypan blue exclusion and propidium iodide staining assays. Activation of the nuclear factor κB (NF-κB) was measured by luciferase reporter assay, and the levels of phospho-signal transducer and activator of transcription (Stat)3 and phospho-extracellular signal-regulated kinase (Erk)1/2 were determined by western blot analysis...

Typhlitis is an abdominal complication of cancer chemotherapy, affecting mostly patients receiving intensive chemotherapeutic regimens with high potential to induce mucosal damage, such as patients with acute leukemia. Despite being relatively frequent, there are no randomized trials or high-quality cohort studies addressing important aspects of the diagnosis and management of the disease. Areas covered: In this review we discuss the gaps in the literature, acknowledging that the evidences for recommendations regarding the management of typhlitis are mostly expert opinion...

BACKGROUND: Current National Comprehensive Cancer Network guidelines for the treatment of retroperitoneal sarcomas (RPS) endorse surgical resection, but the role of radiotherapy (RT) is less clear. We investigate the utilization and benefits of intraoperative RT (IORT) in the treatment of RPS. METHODS: We queried the Surveillance, Epidemiology and End Results (SEER) database (1988-2013) for the utilization of IORT and perioperative external beam RT (EBRT) in patients who underwent surgical resection of RPS...
