BACKGROUND: Obesity is an established risk factor for renal cell carcinoma (RCC). Although genome-wide association studies (GWAS) of RCC have identified several susceptibility loci, additional variants might be missed due to the highly conservative selection. METHODS: We conducted a multiphase study utilizing three independent genome-wide scans at MD Anderson Cancer Center (MDA RCC GWAS and MDA RCC OncoArray) and National Cancer Institute (NCI RCC GWAS), which consisted of a total of 3,530 cases and 5,714 controls, to investigate genetic variations in obesity-related genes and RCC risk...

BACKGROUND: Colorectal cancer (CRC) mortality can be reduced through risk factor modification (adherence to lifestyle recommendations), screening, and improved treatment. This study estimated the potential of these three strategies to modify CRC mortality rates in Norway. METHODS: The potential reduction in CRC mortality due to risk factor modification was estimated using the software Prevent, assuming that 50% of the population in Norway-who do not adhere to the various recommendations concerning prevention of smoking, physical activity, body weight, and intake of alcohol, red/processed meat, and fiber-started to follow the recommendations...

Background Screening programmes consistently underserve indigenous populations despite a higher overall burden of cancer. In this study we explore the likely health gains and cost-effectiveness of a national colorectal cancer (CRC) screening programme for the indigenous Māori population of New Zealand (NZ). Methods A Markov model estimated: health benefits (QALYs), costs and cost-effectiveness of biennial immunochemical faecal occult blood testing (FOBTi) of 50-74 year olds, from 2011. Input parameters came from: literature reviews, the NZ Bowel Screening Programme Pilot, and NZ linked health datasets...

A population-based program promoting the Fecal Occult Blood Test (FOBT) for colorectal cancer screening was introduced in 2008 in Ontario, Canada, where opportunistic screening with colonoscopy had been increasing in frequency. We evaluated the impact of the program on income and immigration-related disparities in screening. We used linked administrative data to calculate colorectal cancer screening rates for eligible Ontarians in each year between 2001/02 (n=2,852,619) and 2013/14 (n=4,139,304). We quantified disparities using an "inequality ratio" of screening rates in the most disadvantaged group relative to the most advantaged group...

Background: Human immunodefieciency virus (HIV)-infected persons are living longer in the era of effective HIV treatment, resulting in an increasing cancer burden in this population. The combined effects of HIV and cancer on mortality are incompletely understood.Methods: We examined whether individuals with both HIV and cancer have excess mortality using data from the HIV/AIDS Cancer Match Study and the National Center for Health Statistics (1996-2010). We compared age, sex, and race-stratified mortality between people with and without HIV or one of the following cancers: lung, breast, prostate, colorectum, anus, Hodgkin lymphoma, or non-Hodgkin lymphoma...

BACKGROUND: While the incidence of colorectal cancer (CRC) is steadily increasing, screening for CRC with conventional approaches is not routinely performed in China. Noninvasive screening methods are attractive options to resolve this issue. Syndecan-2 (SDC2) is frequently methylated in CRC. However, the value of a stool test of methylated SDC2 for the detection of CRC is unknown. METHODS: Methylation status of SDC2 was tested in cell lines and 398 colorectal tissue samples, and further evaluated with 497 stool samples, including 196 from CRC patients, 122 from adenoma patients, and 179 from normal individuals, using real-time methylation-specific PCR (qMSP)...

BACKGROUND: Published evidence indicates that individual use of metformin and statin is associated with reduced cancer mortality. However, their differential and joint effects on pancreatic cancer survival are inconclusive. METHODS: We identified a large population-based cohort of 12,572 patients aged 65 years or older with primary pancreatic ductal adenocarcinoma (PDAC) diagnosed between 2008 and 2011 from the Surveillance, Epidemiology, and End Results (SEER)-Medicare linked database...

BACKGROUND: African Americans (AAs) have the highest lung cancer mortality in the U.S. Genome-wide association studies of germline variants influencing lung cancer survival have not yet been conducted in AAs. We examined five previously reported GWAS catalog variants and explored additional genome-wide associations among AA lung cancer cases. METHODS: Incident non-small cell lung cancer cases (N=286) in the Southern Community Cohort Study were genotyped on the Illumina HumanExome BeadChip...

The association between telomere length (TL) in peripheral blood cells and cancer risk remains inconclusive. We carried out a meta-analysis on prospective studies. The study-specific relative risk estimates were first transformed to a common comparable scale and then were pooled by a random-effects model. The dataset was composed of 13894 cases and 71672 controls from 28 studies in 25 articles. In the comparison of the longest versus shortest third of TL, we observed a marginally positive association between longer TL and higher risk of total cancers (OR=1...

Genome-wide association studies (GWAS) were successful to identify genetic factors robustly associated with lung cancer. This review aims to synthesize the literature in this field and accelerate the translation of GWAS discoveries into results that are closer to clinical applications. A chronological presentation of published GWAS on lung cancer susceptibility, survival and response to treatment is presented. The most important results are tabulated to provide a concise overview in one read. GWAS have reported 45 lung cancer susceptibility loci with varying strength of evidence and highlighted suspected causal genes at each locus...

In this review, we summarize current progress in the genetic epidemiology of epithelial ovarian cancer (EOC), focusing exclusively on elucidating the role of common germline genetic variation in conferring susceptibility to EOC. We provide an overview of the more than 30 EOC risk loci identified to date by genome-wide association studies (GWAS) and describe the contribution of large-scale, cross-cancer type, custom genotyping projects such as the OncoArray and the Collaborative Oncological Gene-Environment Study to locus discovery and replication...

Breast cancer is a leading cancer diagnosis among premenopausal women around the world. Unlike rates in postmenopausal women, incidence rates of advanced breast cancer have increased in recent decades for premenopausal women. Progress in identifying contributors to breast cancer risk among premenopausal women has been constrained by the limited numbers of premenopausal breast cancer cases in individual studies and resulting low statistical power to subcategorize exposures or to study specific subtypes. The Premenopausal Breast Cancer Collaborative Group was established to facilitate cohort-based analyses of risk factors for premenopausal breast cancer by pooling individual-level data from studies participating in the United States National Cancer Institute Cohort Consortium...

Estimates of those living in rural counties vary from 46.2 to 59 million, or 14% to 19% of the U.S. POPULATION: Rural communities face disadvantages compared with urban areas, including higher poverty, lower educational attainment, and lack of access to health services. We aimed to demonstrate rural-urban disparities in cancer and to examine NCI-funded cancer control grants focused on rural populations. Estimates of 5-year cancer incidence and mortality from 2009 to 2013 were generated for counties at each level of the rural-urban continuum and for metropolitan versus nonmetropolitan counties, for all cancers combined and several individual cancer types...

Background: Distant metastatic breast cancer (MBC), including metastases found at diagnosis (de novo) and those occurring later (recurrence), represents the most severe form of the disease, when resource utilization is most intensive. Yet, the number of women living with MBC in the United States is unknown. The objective of this article is to use population-based data to estimate the prevalence of MBC.Methods: We used a back-calculation method to estimate MBC prevalence from U.S. breast cancer mortality and survival from the Surveillance, Epidemiology and End Results (SEER) registries...

BACKGROUND: There are racial disparities in breast cancer mortality. Our purpose was to determine whether racial/ethnic differences in use and discontinuation of AET differed by hormone receptor status and whether discontinuation was associated with mortality. METHODS: We conducted a retrospective cohort study with SEER/Medicare dataset of women age 65 years or older diagnosed with stage I-III breast cancer in Medicare Part-D from 2007-2009, stratified by hormone receptor status...

BACKGROUND: Several studies suggest test characteristics for the faecal immunochemical test (FIT) differ by gender, triggering a debate whether men and women should be screened differently. We used the microsimulation model MISCAN-Colon to evaluate whether screening stratified by gender is cost-effective. METHODS: We estimated gender-specific FIT characteristics based on first round positivity and detection rates observed in a FIT screening pilot (CORERO-1). Subsequently, we used the model to estimate harms, benefits and costs of 480 gender-specific FIT screening strategies and compared them with uniform screening...
