Biopsy variability of lymphocytic infiltration in breast cancer subtypes and the ImmunoSkew score.
(NATURE PORTFOLIO, 2016-11-04)
The number of tumour biopsies required for a good representation of tumours has been controversial. An important factor to consider is intra-tumour heterogeneity, which can vary among cancer types and subtypes. Immune cells ...
A Novel Statistical Method to Diagnose, Quantify and Correct Batch Effects in Genomic Studies.
(NATURE PORTFOLIO, 2017-09-07)
Genome projects now generate large-scale data often produced at various time points by different laboratories using multiple platforms. This increases the potential for batch effects. Currently there are several batch ...
Impact of mutational profiles on response of primary oestrogen receptor-positive breast cancers to oestrogen deprivation.
(NATURE PORTFOLIO, 2016-11-09)
Pre-surgical studies allow study of the relationship between mutations and response of oestrogen receptor-positive (ER+) breast cancer to aromatase inhibitors (AIs) but have been limited to small biopsies. Here in phase I ...
20-Year Risks of Breast-Cancer Recurrence after Stopping Endocrine Therapy at 5 Years.
(MASSACHUSETTS MEDICAL SOC, 2017-11-09)
BACKGROUND: The administration of endocrine therapy for 5 years substantially reduces recurrence rates during and after treatment in women with early-stage, estrogen-receptor (ER)-positive breast cancer. Extending such ...
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 ...
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 ...
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 ...
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 ...
