Increase in power by obtaining 10 or more controls per case when type-1 error is small in large-scale association studies.
(BMC, 2023-06-29)
BACKGROUND: The rule of thumb that there is little gain in statistical power by obtaining more than 4 controls per case, is based on type-1 error α = 0.05. However, association studies that evaluate thousands or millions ...
DNA methylation age in paired tumor and adjacent normal breast tissue in Chinese women with breast cancer.
(BMC, 2023-03-30)
BACKGROUND: Few studies have examined epigenetic age acceleration (AA), the difference between DNA methylation (DNAm) predicted age and chronological age, in relation to somatic genomic features in paired cancer and normal ...
Genome-Wide Meta-Analyses of Breast, Ovarian, and Prostate Cancer Association Studies Identify Multiple New Susceptibility Loci Shared by at Least Two Cancer Types.
(AMER ASSOC CANCER RESEARCH, 2016-09-01)
UNLABELLED: Breast, ovarian, and prostate cancers are hormone-related and may have a shared genetic basis, but this has not been investigated systematically by genome-wide association (GWA) studies. Meta-analyses combining ...
Mosquito control exposures and breast cancer risk: analysis of 1071 cases and 2096 controls from the Ghana Breast Health Study.
(BMC, 2023-12-11)
Epidemiologic data on insecticide exposures and breast cancer risk are inconclusive and mostly from high-income countries. Using data from 1071 invasive pathologically confirmed breast cancer cases and 2096 controls from ...
Etiology of hormone receptor positive breast cancer differs by levels of histologic grade and proliferation.
(WILEY, 2018-08-15)
Limited epidemiological evidence suggests that the etiology of hormone receptor positive (HR+) breast cancer may differ by levels of histologic grade and proliferation. We pooled risk factor and pathology data on 5,905 HR+ ...
PALB2, CHEK2 and ATM rare variants and cancer risk: data from COGS.
(BMJ PUBLISHING GROUP, 2016-12-01)
BACKGROUND: The rarity of mutations in PALB2, CHEK2 and ATM make it difficult to estimate precisely associated cancer risks. Population-based family studies have provided evidence that at least some of these mutations are ...
Prognostic value of automated KI67 scoring in breast cancer: a centralised evaluation of 8088 patients from 10 study groups.
(BIOMED CENTRAL LTD, 2016-10-18)
BACKGROUND: The value of KI67 in breast cancer prognostication has been questioned due to concerns on the analytical validity of visual KI67 assessment and methodological limitations of published studies. Here, we investigate ...
Assessment of polygenic architecture and risk prediction based on common variants across fourteen cancers.
(NATURE PORTFOLIO, 2020-07-03)
Genome-wide association studies (GWAS) have led to the identification of hundreds of susceptibility loci across cancers, but the impact of further studies remains uncertain. Here we analyse summary-level data from GWAS of ...
Large-scale genotyping identifies 41 new loci associated with breast cancer risk.
(NATURE PUBLISHING GROUP, 2013-04-01)
Breast cancer is the most common cancer among women. Common variants at 27 loci have been identified as associated with susceptibility to breast cancer, and these account for ∼9% of the familial risk of the disease. We ...
Cross-Cancer Genome-Wide Analysis of Lung, Ovary, Breast, Prostate, and Colorectal Cancer Reveals Novel Pleiotropic Associations.
(AMER ASSOC CANCER RESEARCH, 2016-09-01)
Identifying genetic variants with pleiotropic associations can uncover common pathways influencing multiple cancers. We took a two-stage approach to conduct genome-wide association studies for lung, ovary, breast, prostate, ...
