The activation of the Wnt/β-catenin signaling cascade has been well studied and documented in colorectal cancer (CRC). The long-term use of non-steroidal anti-inflammatory drugs (NSAIDs) has been shown to reduce the incidence and risk of death from CRC in numerous epidemiological studies. The NSAID sulindac has also been reported to cause regression of precancerous adenomas in individuals with familial adenomatous polyposis who are at high risk of developing CRC. The mechanism responsible for cancer chemopreventive activity of NSAIDs is not well understood but may be unrelated to their cyclooxygenase inhibitory activity...

BACKGROUND: It is unclear if use of common antihypertensive medications influences the risk of adverse breast cancer outcomes. METHODS: Using the linked Surveillance, Epidemiology and End-Results (SEER)-Medicare database, we identified 14,766 women between ages 66 and 80 years diagnosed with incident stage I/II breast cancer between 2007-2011. Medicare Part D data were obtained to characterize women's post-cancer use of various antihypertensive medications. Outcomes included a second breast cancer event (SBCE, a composite outcome defined as the first of a recurrence or a second contralateral primary breast cancer), breast cancer recurrence, and breast-cancer specific mortality...

Cancer from the gastrointestinal tract and its associated excretory organs will occur in over 300,000 Americans in 2017, with colorectal cancer responsible for over forty percent of that burden; there will be over 150,000 deaths from this group of cancers in the same time period. Disparities among subgroups related to these cancers' incidence and mortality exist. The epidemiology and risk factors associated with each cancer bear out differences for racial groups in the United States. Esophageal adenocarcinoma is more frequent in Non-Hispanic Whites, whereas esophageal squamous cell carcinoma with risk factors of tobacco and alcohol is more frequent among Blacks...

Patients with advanced-stage non-small cell lung carcinoma (NSCLC) harboring an ALK rearrangement, detected from a tissue sample, can benefit from targeted ALK inhibitor treatment. Several increasingly effective ALK inhibitors are now available for treatment of patients. However, despite an initial favorable response to treatment, in most cases relapse or progression occurs due to resistance mechanisms mainly caused by mutations in the tyrosine kinase domain of ALK. The detection of an ALK rearrangement is pivotal and can be done using different methods, which have variable sensitivity and specificity depending, in particular, on the quality and quantity of the patient's sample...

BACKGROUND: There is no uniformly adopted cutoff value to define "young patients" with breast cancer. This study was designed to determine an optimal cutoff value, to investigate prognostic factors and to explore gene expression profiles of young female breast cancer. MATERIALS AND METHODS: The Surveillance, Epidemiology, and End Results database was examined to identify cases of female breast cancer diagnosed between 2000 and 2007. The optimal cutoff value for young age was determined using the X-tile program (Yale University, version 3...

REVIEW
Thomas Günther, Adam Grundhoff
Molecular and epidemiological evidence links Kaposi sarcoma-associated herpesvirus (KSHV) to a number of malignancies of endothelial or B cell origin. As for most virus-associated cancers, however, the tumor initiating and promoting events remain poorly understood. Given the emerging role of epigenetic alterations as drivers of human cancers, an interesting (and as of yet under-explored) hypothesis is that viral manipulation of host cell chromatin may contribute to the pathogenesis of KSHV-associated tumors...

Colorectal cancer (CRC) represents a significant health burden worldwide, comprising approximately 10% of annual cancer cases globally. Hepatic metastases are the most common site of CRC metastasis, and are the leading cause of death in CRC patients. There is strong epidemiologic evidence for an inverse association between vitamin D status and risk of CRC; however, the role of vitamin D in the natural history of liver metastases has not yet been investigated. Several researchers have proposed hallmarks of metastases; crucially, metastases can be blocked by interrupting just one rate-limiting step...

PURPOSE: Squamous cell cancer (SCC) is a rare histological subtype of rectal cancer. It is unclear whether SCC should be treated by multimodal therapy, including surgery, or by chemoradiation alone. The objective of the study was to define an optimal treatment strategy. METHODS: Patients with rectal cancer and SCC histology were identified in the Surveillance Epidemiology and End Results Database between 1990 and 2013. According to treatment, three groups were defined: radiotherapy and surgery (RT/SX), radiotherapy (RT), and surgery (SX)...

INTRODUCTION: Although black patients with endometrial cancer (EC) have worse survival compared with white patients, the interaction between age/race has not been examined. The primary objective was to evaluate the impact of age at diagnosis on racial disparities in disease presentation and outcome in EC. METHODS: We evaluated women diagnosed with EC between 1991 and 2010 from the Surveillance, Epidemiology, and End Results. Mutation status for TP53 or PTEN, or with the aggressive integrative, transcript-based, or somatic copy number alteration-based molecular subtype were acquired from the Cancer Genome Atlas...

Disregarding the rising alarm on the hazardous nature of various phthalates and their metabolites, ruthless usage of phthalates as plasticizer in plastics and as additives in innumerable consumer products continues due low their cost, attractive properties, and lack of suitable alternatives. Globally, in silico computational, in vitro mechanistic, in vivo preclinical and limited clinical or epidemiological human studies showed that over a dozen phthalates and their metabolites ingested passively by man from the general environment, foods, drinks, breathing air, and routine household products cause various dysfunctions...

BACKGROUND: Mortality statistics by age, sex and cause are the foundation of basic health data required for health status assessment, epidemiological research and formation of health policy. Close to half the deaths in Malaysia occur outside a health facility, are not attended by medical personnel, and are given a lay opinion as to the cause of death, leading to poor quality of data from vital registration. Verbal autopsy (VA) is a very useful tool in diagnosing broad causes of deaths for events that occur outside health facilities...
