Current studies do not accurately evaluate the influence of tumor location on survival of colorectal cancer patients. This study aimed to explore whether tumor location could be identified as another high-risk factor in stage II colorectal cancer by using data identified from the Surveillance, Epidemiology, and End Results database. All colorectal cancer patients between 2004 and 2008 were grouped into three according to tumor location. Of 33,789 patients diagnosed with stage II colorectal cancer, 46.8% were right colon cancer, 37...

Although the Asian American population has steadily increased since 1980s, there remains a paucity of literature on cancer screening utilization on this population. The purpose of this study was to evaluate preventive health and screening practices by examining demographic predictors of health and screening behaviors among 217 Asian Americans living in state of Michigan. Several demographic and acculturation-related factors were found to be associated with "ever screened" status in the bivariate analyses. This included the examination of the relationships among refugee status and cancer screening practices among Asian Americans...

BACKGROUND: The American Joint Committee on Cancer (AJCC) recently released its 8th edition staging system, which created a separate staging system for gastric cancer patients who have undergone preoperative therapy (ypStage). The objective of this retrospective study was to apply the new ypStage to patients who have undergone preoperative therapy and potentially curative gastrectomy. METHODS: We collected data from a prospectively maintained institutional database of gastric cancer patients who underwent potentially curative gastrectomy after preoperative therapy (1995-2015)...

BACKGROUND: High stability and disease-specific disarrangements suggest that microRNA molecules (miRNAs) present in body fluids are ideally suited for diagnostic applications, including gastric cancer (GC). However, the actual source of circulating miRNA biomarkers in GC has not been adequately evaluated, particularly in the Western populations that have some distinct characteristics compared with Asian patients. METHODS: Twenty treatment-naive patients with GC along with 20 cancer-free controls were recruited...

BACKGROUND: A number of studies had reported the association between tumor necrosis factor-alpha (TNF-α) gene polymorphisms and head and neck cancer (HNC) risk. However, the results remained controversial. Therefore, we performed a meta-analysis to derive a more precise evaluation of the association between TNF-α-308G/A polymorphism and overall HNC risk and evaluated influence of cancer types and ethnicities. METHODS: A systematic literature search was performed using Pubmed, Embase, Cochrane Library, and Web of science...

Genome-wide association studies (GWAS) of cancer have identified more than 700 risk loci, of which ~80% of were first discovered in European ancestry populations, ~15% in East Asians, 3% in multiethnic scans, and less than 1% in African and Latin American populations. These percentages closely mirror the distribution of samples included in the discovery phase of cancer GWAS to date (84% European, 11% East Asian, 4% African and 1% Latin American ancestry). GWAS in non-European populations have provided insight into ancestry-specific variation in cancer and have pointed to regions of susceptibility that are of particular importance in certain populations...

BACKGROUND: Numerous clinical trials show crizotinib has promising efficacy for anaplastic lymphoma kinase (ALK) positive non-small cell lung cancer (NSCLC) patients which trigger the substitution of traditional chemotherapy to be the current standard first-line treatment for these patients. Conversely, few reports systematically analyze toxicity of crizotinib. Hence, we performed a first meta-analysis to determine the risk of crizotinib-related severe adverse events (SAEs) and fatal adverse events (FAEs) in ALK positive NSCLC patients...

Single nucleotide polymorphisms (SNPs) in three microRNAs (miRNAs), rs2910164 in miR-146a, rs11614913 in miR-196a2, and rs3746444 in miR-499, have been associated with breast cancer (BC) susceptibility, but the evidence is conflicting. To obtain a more robust assessment of the association between these miRNA variants and BC risk, we carried out a meta-analysis through systematic literature retrieval from the PubMed and Embase databases. A total of 9 case-control studies on rs2910164, 12 on rs11614913, and 7 on rs3746444 were included...

The prevalence of TMPRSS2-ERG fusions in prostate cancer varies by race. However, such somatic aberration and its association with prognostic factors have neither been studied in a West African population nor been systematically reviewed in the context of racial differences. We used immunohistochemistry to assess ERG expression as the established surrogate of ERG fusion genes among 262 prostate cancer biopsies from the Ghana Prostate Study. Poisson regression with robust variance estimation provided prevalence ratios and 95% confidence intervals of ERG expression in relation to patients' characteristics...

Inorganic arsenic (iAs) in drinking water varies geographically and is prevalent worldwide. While exposures in the US are generally low, there are some areas with higher levels of naturally occurring iAs (potentially >100μg/L) where residents rely on unregulated drinking water wells. Much of the evidence on the association between iAs and cancer comes from epidemiological studies conducted in South American and Asian populations. These populations have generally been exposed to much higher levels of iAs and have differing underlying characteristics, both of which make comparing them to Western populations difficult...

BACKGROUND: A significant proportion of patients never receive curative-intent surgery for resectable gastric cancer (GC). The primary aims of this study were to identify disparities and targetable risk factors associated with failure to operate in the context of national trends in surgical rates for resectable GC. METHODS: The National Cancer Database was used to identify patients with resectable GC (adenocarcinoma, clinical stage IA-IIIC, 2004-2013). Multivariate modeling was used to identify predictors of resection and to analyze the impact of surgery on overall survival (OS)...

Head and neck squamous cell carcinoma (HNSCC) is the sixth most common cancer worldwide. It accounts for 2.5% of all new cancer cases and 1.9% of all cancer deaths annually. More than 90% of oral cancers (occurring in the mouth, lip, and tongue) are oral squamous cell carcinoma. The incidence rate of oral cancer varies widely throughout the world, with an evident prevalence in South Asian countries. This high incidence occurs in correlation with oral cancer-associated behaviors such as alcohol, tobacco use...

BACKGROUND: Sarcomas are a rare type of breast malignancies and malignant peripheral nerve sheath tumors of the breast are even rarer. There are no specific clinical and radiological features for the diagnosis of this tumor and histological features are also reported to be nonspecific. Therefore, immunohistochemistry is required for its diagnosis. A definitive treatment protocol is unavailable because of its rarity. CASE PRESENTATION: We report a case of a sporadic form of breast malignant peripheral nerve sheath tumor found in a 16-year-old Asian Bangladeshi girl...
