Genome-wide association studies in European and Asian populations have consistently identified chromosome 5p15.33 as a lung cancer susceptibility region. To investigate further the genetic architecture of common variants in this region, we conducted a two-stage fine-mapping analysis discovered by targeted resequencing of 200 cases and 300 controls individually, and validated in multiethnic lung cancer GWASs with 12,843 cases and 12,639 controls. Two independent variants were identified in approximate conditional analysis with GCTA and consistently validated in lung cancer GWASs in both Asian and European populations...

Background and Aims: The association between inflammatory bowel disease (IBD) and cancer remains poorly defined in Asian populations. Therefore, we conducted a nationwide population-based study to determine the cancer risk in Korean patients with IBD. Methods: Using the National Health Insurance claims data, we collected data on patients diagnosed with IBD (5,595 Crohn's disease [CD] and 10,049 ulcerative colitis [UC]) from 2011 to 2014. Standardized incidence ratios (SIRs) of overall and site-specific cancers in IBD patients in comparison with the general population were calculated...

Priyanka Prasad, Dona Sinha
The impact of chronic low-level groundwater arsenic (As) exposure [in the range above the WHO-recommended limit of 10 g/L but ≤50 μg/L (permissible limit of As for many Asian countries)] was investigated for cross talk of inflammatory changes and expression of phagocytic receptors of exposed rural women (N, 45) from districts of 24 Parganas (south) and in matched control groups (N, 43) [As ≤10 μg/L] from the same district. Systemic inflammation was evident from the upregulated levels of pro-inflammatory mediators like tumor necrosis factor-α (TNF-α); interleukins (ILs) like IL-6, IL-8, and IL-12; and C-reactive protein (CRP) in the sera and upregulated expression of protein kinase B phosphorylated at ser473 (pAKTser473)/nuclear factor-κB (NF-κB)/TNF-α axis in the leukocytes of exposed women with respect to control...

Polymorphisms in X-ray repair cross-complementing (XRCC) genes have been implicated in altering the risk of various urological cancers. However, the results of reported studies are controversial. To ascertain whether polymorphisms in XRCC genes are associated with the risk of urological neoplasms, we conducted present updated meta-analysis and systematic review. Summary odds ratios (ORs) and corresponding 95% confidence intervals (CIs) were used to estimate the association. Finally, 54 publications comprising 129 case-control studies for twelve polymorphisms in five XRCC genes were enrolled...

People of color are at significantly higher risk in mortality from skin cancers, such as melanoma, than Caucasians. Around 4,500,000 people of color are affected by skin cancer The five-year survival rates from melanoma are 81.1% for Hispanics, 80.2% for Asians, 72.2% for African- Americans, and 89.6% for Caucasians. For this reason, it is important to ensure the scientific literature reflects the most up to date recommendations and treatment for blacks regarding skin cancer. Therefore the authors conducted a "gap analysis" on the current treatment of skin cancer in people of color...

BACKGROUND: Gastric cancer is the fourth most common cancer in men and the sixth among women, except for non-melanoma skin tumors, in Brazil. Epidemiological evidences reveal the multifactorial etiology of this cancer, highlighting risk factors such as: infection by the bacterium Helicobacter pylori, advanced age, smoking, chronic alcohol abuse, eating habits and genetic polymorphisms. Considering the context of genetic polymorphisms, there is the absence of the GSTM1 gene. The lack of GSTM1 function to detoxify xenobiotics and promote defense against oxidative stress leads to increased DNA damage, promoting gastric carcinogenesis...

REVIEW
Miriam Joy C Calaguas, Johannes A Gubat
The accessibility of radiotherapy in Southeast Asia, a region characterized by diversity in both economy and culture, differ widely among its member countries. In most countries, access is not universal and is generally limited by radiotherapy resources and the health-seeking behavior of patients. This in turn relates to the current health policy in place, the practice of radiation oncology, and cultural factors such as religion and family dynamics. Although it is clear that radiotherapy access parallel economic development, it is also affected by different social factors that work to facilitate or impede its improvement...
