Evaluation of diffusion-weighted MRI and (18F) fluorothymidine-PET biomarkers for early response assessment in patients with operable non-small cell lung cancer treated with neoadjuvant chemotherapy.
(Oxford University Press (OUP), 2019-01-01)
OBJECTIVE: To correlate changes in the apparent diffusion coefficient (ADC) from diffusion-weighted (DW)-MRI and standardised uptake value (SUV) from fluorothymidine (18FLT)-PET/CT with histopathological estimates of ...
Five endometrial cancer risk loci identified through genome-wide association analysis.
(NATURE PORTFOLIO, 2016-06-01)
We conducted a meta-analysis of three endometrial cancer genome-wide association studies (GWAS) and two follow-up phases totaling 7,737 endometrial cancer cases and 37,144 controls of European ancestry. Genome-wide imputation ...
Real-time intrafraction motion monitoring in external beam radiotherapy.
(IOP PUBLISHING LTD, 2019-08-07)
Radiotherapy (RT) aims to deliver a spatially conformal dose of radiation to tumours while maximizing the dose sparing to healthy tissues. However, the internal patient anatomy is constantly moving due to respiratory, ...
Breast MRI segmentation for density estimation: Do different methods give the same results and how much do differences matter?
(WILEY, 2017-09-01)
PURPOSE: To compare two methods of automatic breast segmentation with each other and with manual segmentation in a large subject cohort. To discuss the factors involved in selecting the most appropriate algorithm for ...
Evaluation of MRI-derived surrogate signals to model respiratory motion.
(IOP PUBLISHING LTD, 2020-07-01)
An MR-Linac can provide motion information of tumour and organs-at-risk before, during, and after beam delivery. However, MR imaging cannot provide real-time high-quality volumetric images which capture breath-to-breath ...
Consistent and invertible deformation vector fields for a breathing anthropomorphic phantom: a post-processing framework for the XCAT phantom.
(IOP PUBLISHING LTD, 2020-08-13)
Breathing motion is challenging for radiotherapy planning and delivery. This requires advanced four-dimensional (4D) imaging and motion mitigation strategies and associated validation tools with known deformations. Numerical ...
Neurotoxicity from immune-checkpoint inhibition in the treatment of melanoma: a single centre experience and review of the literature.
(OXFORD UNIV PRESS, 2017-02-01)
BACKGROUND: Treatment with immune checkpoint inhibitors (ICPi) has greatly improved survival for patients with advanced melanoma in recent years. Anti-CTLA-4 and anti-PD1 antibodies have been approved following large Phase ...
The long-term prognostic and predictive capacity of cyclin D1 gene amplification in 2305 breast tumours.
(BMC, 2019-02-28)
BACKGROUND: Use of cyclin D1 (CCND1) gene amplification as a breast cancer biomarker has been hampered by conflicting assessments of the relationship between cyclin D1 protein levels and patient survival. Here, we aimed ...
A pan-cancer analysis of the frequency of DNA alterations across cell cycle activity levels.
(SPRINGERNATURE, 2020-08-06)
Pan-cancer genomic analyses based on the magnitude of pathway activity are currently lacking. Focusing on the cell cycle, we examined the DNA mutations and chromosome arm-level aneuploidy within tumours with low, intermediate ...
