Identification of ten variants associated with risk of estrogen-receptor-negative breast cancer.
(NATURE PORTFOLIO, 2017-12-01)
Most common breast cancer susceptibility variants have been identified through genome-wide association studies (GWAS) of predominantly estrogen receptor (ER)-positive disease. We conducted a GWAS using 21,468 ER-negative ...
Genome-wide association and transcriptome studies identify target genes and risk loci for breast cancer.
(NATURE PORTFOLIO, 2019-04-15)
Genome-wide association studies (GWAS) have identified more than 170 breast cancer susceptibility loci. Here we hypothesize that some risk-associated variants might act in non-breast tissues, specifically adipose tissue ...
Association analyses identify 31 new risk loci for colorectal cancer susceptibility.
(NATURE PUBLISHING GROUP, 2019-05-14)
Colorectal cancer (CRC) is a leading cause of cancer-related death worldwide, and has a strong heritable basis. We report a genome-wide association analysis of 34,627 CRC cases and 71,379 controls of European ancestry that ...
BRCA2 Hypomorphic Missense Variants Confer Moderate Risks of Breast Cancer.
(AMER ASSOC CANCER RESEARCH, 2017-06-01)
Breast cancer risks conferred by many germline missense variants in the BRCA1 and BRCA2 genes, often referred to as variants of uncertain significance (VUS), have not been established. In this study, associations between ...
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 ...
Trans-abdominal in vivo placental vessel occlusion using High Intensity Focused Ultrasound.
(NATURE PORTFOLIO, 2018-09-11)
Pre-clinically, High Intensity Focused Ultrasound (HIFU) has been shown to safely and effectively occlude placental blood vessels in the acute setting, when applied through the uterus. However, further development of the ...
Heterogeneity in global gene expression profiles between biopsy specimens taken peri-surgically from primary ER-positive breast carcinomas.
(BIOMED CENTRAL LTD, 2016-04-01)
BACKGROUND: Gene expression is widely used for the characterisation of breast cancers. Variability due to tissue heterogeneity or measurement error or systematic change due to peri-surgical procedures can affect measurements ...
Breast cancer risk following Hodgkin lymphoma radiotherapy in relation to menstrual and reproductive factors.
(NATURE PUBLISHING GROUP, 2013-06-11)
BACKGROUND: Women treated with supradiaphragmatic radiotherapy (sRT) for Hodgkin lymphoma (HL) at young ages have a substantially increased breast cancer risk. Little is known about how menarcheal and reproductive factors ...
Late normal tissue effects in the arm and shoulder following lymphatic radiotherapy: Results from the UK START (Standardisation of Breast Radiotherapy) trials.
(ELSEVIER IRELAND LTD, 2018-01-01)
BACKGROUND AND PURPOSE: Adjuvant lymphatic radiotherapy (LNRT) is recommended for selected axillary node positive women with early breast cancer. We investigated whether hypofractionated LNRT is safe combined with ...
Genetic variation at CYP3A is associated with age at menarche and breast cancer risk: a case-control study.
(BMC, 2014-05-26)
INTRODUCTION: We have previously shown that a tag single nucleotide polymorphism (rs10235235), which maps to the CYP3A locus (7q22.1), was associated with a reduction in premenopausal urinary estrone glucuronide levels and ...
