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 ...
Adjuvant Olaparib for Patients with BRCA1- or BRCA2-Mutated Breast Cancer.
(MASSACHUSETTS MEDICAL SOC, 2021-06-24)
BACKGROUND: Poly(adenosine diphosphate-ribose) polymerase inhibitors target cancers with defects in homologous recombination repair by synthetic lethality. New therapies are needed to reduce recurrence in patients with ...
Aggregation tests identify new gene associations with breast cancer in populations with diverse ancestry.
(BMC, 2023-01-26)
BACKGROUND: Low-frequency variants play an important role in breast cancer (BC) susceptibility. Gene-based methods can increase power by combining multiple variants in the same gene and help identify target genes. METHODS: ...
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 ...
Age- and Tumor Subtype-Specific Breast Cancer Risk Estimates for CHEK2*1100delC Carriers.
(LIPPINCOTT WILLIAMS & WILKINS, 2016-08-10)
PURPOSE: CHEK2*1100delC is a well-established breast cancer risk variant that is most prevalent in European populations; however, there are limited data on risk of breast cancer by age and tumor subtype, which limits its ...
Two truncating variants in FANCC and breast cancer risk.
(NATURE PORTFOLIO, 2019-08-29)
Fanconi anemia (FA) is a genetically heterogeneous disorder with 22 disease-causing genes reported to date. In some FA genes, monoallelic mutations have been found to be associated with breast cancer risk, while the risk ...
Mapping the breast cancer metastatic cascade onto ctDNA using genetic and epigenetic clonal tracking.
(NATURE PORTFOLIO, 2020-03-27)
Circulating tumour DNA (ctDNA) allows tracking of the evolution of human cancers at high resolution, overcoming many limitations of tissue biopsies. However, exploiting ctDNA to determine how a patient's cancer is evolving ...
