(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 ... -
Biomarkers for site-specific response to neoadjuvant chemotherapy in epithelial ovarian cancer: relating MRI changes to tumour cell load and necrosis.
(SPRINGERNATURE, 2021-03-16)BACKGROUND: Diffusion-weighted magnetic resonance imaging (DW-MRI) potentially interrogates site-specific response to neoadjuvant chemotherapy (NAC) in epithelial ovarian cancer (EOC). METHODS: Participants with newly ... -
