How informed is declared altruism in clinical trials? A qualitative interview study of patient decision-making about the QUEST trials (Quality of Life after Mastectomy and Breast Reconstruction).
(BMC, 2016-09-02)
BACKGROUND: Randomised controlled trials (RCTs) often fail to recruit sufficient participants, despite altruism being cited as their motivation. Previous investigations of factors influencing participation decisions have ...
A novel approach to evaluate spatial resolution of MRI clinical images for optimization and standardization of breast screening protocols.
(AMER ASSOC PHYSICISTS MEDICINE AMER INST PHYSICS, 2016-12-01)
PURPOSE: Stringent quality assurance is required in MRI breast screening to ensure that different scanners and imaging protocols reach similar diagnostic performance. The authors propose a methodology, based on power ...
CYP3A7*1C allele is associated with reduced levels of 2-hydroxylation pathway oestrogen metabolites.
(NATURE PUBLISHING GROUP, 2017-01-31)
BACKGROUND: Endogenous sex hormones are well-established risk factors for breast cancer; the contribution of specific oestrogen metabolites (EMs) and/or ratios of specific EMs is less clear. We have previously identified ...
Height and Body Mass Index as Modifiers of Breast Cancer Risk in BRCA1/2 Mutation Carriers: A Mendelian Randomization Study.
(OXFORD UNIV PRESS INC, 2019-04-01)
BACKGROUND: BRCA1/2 mutations confer high lifetime risk of breast cancer, although other factors may modify this risk. Whether height or body mass index (BMI) modifies breast cancer risk in BRCA1/2 mutation carriers remains ...
Predictors of prolonged benefit from palbociclib plus fulvestrant in women with endocrine-resistant hormone receptor-positive/human epidermal growth factor receptor 2-negative metastatic breast cancer in PALOMA-3.
(ELSEVIER SCI LTD, 2018-11-01)
BACKGROUND: The addition of palbociclib to fulvestrant improved clinical outcomes over placebo-fulvestrant in endocrine-pretreated metastatic breast cancer (MBC) patients in PALOMA-3. Here, we examined factors predictive ...
Integrated Pharmacodynamic Analysis Identifies Two Metabolic Adaption Pathways to Metformin in Breast Cancer.
(CELL PRESS, 2018-11-06)
Late-phase clinical trials investigating metformin as a cancer therapy are underway. However, there remains controversy as to the mode of action of metformin in tumors at clinical doses. We conducted a clinical study ...
Dicentric Dose Estimates for Patients Undergoing Radiotherapy in the RTGene Study to Assess Blood Dosimetric Models and the New Bayesian Method for Gradient Exposure.
(RADIATION RESEARCH SOC, 2018-09-20)
The RTGene study was focused on the development and validation of new transcriptional biomarkers for prediction of individual radiotherapy patient responses to ionizing radiation. In parallel, for validation purposes, this ...
Maternal breast cancer risk in relation to birthweight and gestation of her offspring.
(BMC, 2018-10-05)
BACKGROUND: Parity and age at first pregnancy are well-established risk factors for breast cancer, but the effects of other characteristics of pregnancies are uncertain and the literature is inconsistent. METHODS: In a ...
INTEND II randomized clinical trial of intraoperative duct endoscopy in pathological nipple discharge.
(WILEY, 2018-11-01)
BACKGROUND: The majority of lesions resulting in pathological nipple discharge are benign. Conventional surgery is undirected and targeting the causative lesion by duct endoscopy may enable more accurate surgery with fewer ...
Reproductive profiles and risk of breast cancer subtypes: a multi-center case-only study.
(BMC, 2017-12-01)
BACKGROUND: Previous studies have shown that reproductive factors are differentially associated with breast cancer (BC) risk by subtypes. The aim of this study was to investigate associations between reproductive factors ...
