Association of Body Mass Index and Age With Subsequent Breast Cancer Risk in Premenopausal Women.
(AMER MEDICAL ASSOC, 2018-11-01)IMPORTANCE: The association between increasing body mass index (BMI; calculated as weight in kilograms divided by height in meters squared) and risk of breast cancer is unique in cancer epidemiology in that a crossover ... -
Association of Bone Metastatic Burden With Survival Benefit From Prostate Radiotherapy in Patients With Newly Diagnosed Metastatic Prostate Cancer: A Secondary Analysis of a Randomized Clinical Trial.
(AMER MEDICAL ASSOC, 2021-04-01)IMPORTANCE: Prostate radiotherapy (RT) improves survival in men with low-burden metastatic prostate cancer. However, owing to the dichotomized nature of metastatic burden criteria, it is not clear how this benefit varies ... -
Association of breast cancer risk in BRCA1 and BRCA2 mutation carriers with genetic variants showing differential allelic expression: identification of a modifier of breast cancer risk at locus 11q22.3.
(SPRINGER, 2017-01-01)PURPOSE: Cis-acting regulatory SNPs resulting in differential allelic expression (DAE) may, in part, explain the underlying phenotypic variation associated with many complex diseases. To investigate whether common variants ... -
Association of Genomic Domains in BRCA1 and BRCA2 with Prostate Cancer Risk and Aggressiveness.
(AMER ASSOC CANCER RESEARCH, 2020-02-01)Pathogenic sequence variants (PSV) in BRCA1 or BRCA2 (BRCA1/2) are associated with increased risk and severity of prostate cancer. We evaluated whether PSVs in BRCA1/2 were associated with risk of overall prostate cancer ... -
Atlas of prostate cancer heritability in European and African-American men pinpoints tissue-specific regulation.
(NATURE PUBLISHING GROUP, 2016-04-07)Although genome-wide association studies have identified over 100 risk loci that explain ∼33% of familial risk for prostate cancer (PrCa), their functional effects on risk remain largely unknown. Here we use genotype data ... -
ATR Inhibition Potentiates the Radiation-induced Inflammatory Tumor Microenvironment.
(AMER ASSOC CANCER RESEARCH, 2019-06-01)PURPOSE: ATR inhibitors (ATRi) are in early phase clinical trials and have been shown to sensitize to chemotherapy and radiotherapy preclinically. Limited data have been published about the effect of these drugs on the ... -
Audit feasibility for geometric distortion in magnetic resonance imaging for radiotherapy.
(ELSEVIER, 2020-07-01)BACKGROUND AND PURPOSE: Magnetic Resonance Imaging (MRI) is increasingly being used in radiotherapy (RT). However, geometric distortions are a known challenge of using MRI in RT. The aim of this study was to demonstrate ... -
Automatic reconstruction of the delivered dose of the day using MR-linac treatment log files and online MR imaging.
(ELSEVIER IRELAND LTD, 2020-01-10)BACKGROUND AND PURPOSE: Anatomical changes during external beam radiotherapy prevent the accurate delivery of the intended dose distribution. Resolving the delivered dose, which is currently unknown, is crucial to link ... -
Automatic Segmentation of Pelvic Cancers Using Deep Learning: State-of-the-Art Approaches and Challenges.
(MDPI, 2021-10-22)The recent rise of deep learning (DL) and its promising capabilities in capturing non-explicit detail from large datasets have attracted substantial research attention in the field of medical image processing. DL provides ... -
Baseline results from the UK SIGNIFY study: a whole-body MRI screening study in TP53 mutation carriers and matched controls.
(SPRINGER, 2017-07-01)In the United Kingdom, current screening guidelines for TP53 germline mutation carriers solely recommends annual breast MRI, despite the wide spectrum of malignancies typically seen in this group. This study sought to ... -
Baseline Surveillance in Li-Fraumeni Syndrome Using Whole-Body Magnetic Resonance Imaging: A Meta-analysis.
(AMER MEDICAL ASSOC, 2017-12-01)IMPORTANCE: Guidelines for clinical management in Li-Fraumeni syndrome, a multiple-organ cancer predisposition condition, are limited. Whole-body magnetic resonance imaging (WBMRI) may play a role in surveillance of this ... -
Beam modeling and VMAT performance with the Agility 160-leaf multileaf collimator.
(2013-05-06)The Agility multileaf collimator (Elekta AB, Stockholm, Sweden) has 160 leaves of projected width 0.5 cm at the isocenter, with maximum leaf speed 3.5 cms-1. These characteristics promise to facilitate fast and accurate ... -
Beam selection for stereotactic ablative radiotherapy using Cyberknife with multileaf collimation.
(ELSEVIER SCI LTD, 2018-12-20)The Cyberknife system (Accuray Inc., Sunnyvale, CA) enables radiotherapy using stereotactic ablative body radiotherapy (SABR) with a large number of non-coplanar beam orientations. Recently, a multileaf collimator has also ... -
Best Current Practice and Research Priorities in Active Surveillance for Prostate Cancer-A Report of a Movember International Consensus Meeting.
(ELSEVIER, 2023-01-27)BACKGROUND: Active surveillance (AS) is recommended for low-risk and some intermediate-risk prostate cancer. Uptake and practice of AS vary significantly across different settings, as does the experience of surveillance-from ... -
Biological effects of combination therapy with oncolytic reovirus and palbociclib
(Institute of Cancer Research (University Of London), 2021-09-30)Reovirus type 3 Dearing (RtD3) is an oncolytic dsRNA virus with limited single-agent activity in clinical studies but has potential for use in combination regimens. Herein, I sought to discover synergistic drug-virotherapy ... -
