Feasibility of tumour-focused adaptive radiotherapy for bladder cancer on the MR-linac.
(ELSEVIER IRELAND LTD, 2022-07-01)Bladder tumour-focused magnetic resonance image-guided adaptive radiotherapy using a 1.5 Tesla MR-linac is feasible. A full online workflow adapting to anatomy at each fraction is achievable in approximately 30 min. ... -
Feasibility study of combined dynamic imaging and lymphaticovenous anastomosis surgery for breast cancer-related lymphoedema.
(2019-01)Background Breast cancer-related lymphoedema (BCRL) presents a significant healthcare burden and adversely affects quality of life of breast cancer survivors. A prospective feasibility study was performed on lymphaticovenous ... -
Features and Management of Late Relapse of Nonseminomatous Germ Cell Tumour.
(ELSEVIER, 2021-06-07)BACKGROUND: Late relapse (LR) of nonseminomatous germ cell tumour (NSGCT) is uncommon, with limited data published. LR is defined as relapse occurring after a disease-free interval of 2 yr. OBJECTIVE: To review features ... -
Fever of Unknown Origin: the Value of FDG-PET/CT.
(2018-03)Fever of unknown origin (FUO) is commonly defined as fever higher than 38.3°C on several occasions during at least 3 weeks with uncertain diagnosis after a number of obligatory investigations. The differential diagnosis ... -
FFPE breast tumour blocks provide reliable sources of both germline and malignant DNA for investigation of genetic determinants of individual tumour responses to treatment.
(SPRINGER, 2018-08-01)BACKGROUND: Bio-banked formalin-fixed paraffin-embedded (FFPE) tissues provide an excellent opportunity for translational genomic research. Historically matched blood has not always been collected as a source of germline ... -
Final analyses of OPTiM: a randomized phase III trial of talimogene laherparepvec versus granulocyte-macrophage colony-stimulating factor in unresectable stage III-IV melanoma.
(BMJ PUBLISHING GROUP, 2019-06-06)BACKGROUND: Talimogene laherparepvec is an oncolytic immunotherapy approved in the US, Europe, Australia and Switzerland. We report the final planned analysis of OPTiM, a randomized open-label phase III trial in patients ... -
Fine-mapping of 150 breast cancer risk regions identifies 191 likely target genes.
(NATURE PORTFOLIO, 2020-01-07)Genome-wide association studies have identified breast cancer risk variants in over 150 genomic regions, but the mechanisms underlying risk remain largely unknown. These regions were explored by combining association ... -
Fine-mapping of prostate cancer susceptibility loci in a large meta-analysis identifies candidate causal variants.
(NATURE PORTFOLIO, 2018-06-11)Prostate cancer is a polygenic disease with a large heritable component. A number of common, low-penetrance prostate cancer risk loci have been identified through GWAS. Here we apply the Bayesian multivariate variable ... -
Fine-Scale Mapping at 9p22.2 Identifies Candidate Causal Variants That Modify Ovarian Cancer Risk in BRCA1 and BRCA2 Mutation Carriers.
(PUBLIC LIBRARY SCIENCE, 2016-07-27)Population-based genome wide association studies have identified a locus at 9p22.2 associated with ovarian cancer risk, which also modifies ovarian cancer risk in BRCA1 and BRCA2 mutation carriers. We conducted fine-scale ... -
Finite Element simulation of methods for improving tissue ultrasound backscatter coefficient estimation
(Institute of Cancer Research (University Of London), 2023-10-02)This thesis will describe the efforts to generate Finite Element simulations of methods to improve the accuracy and reliability of backscatter coefficient methods (BSC). BSC measurements are a promising diagnostic tool in ... -
First evaluation of the feasibility of MLC tracking using ultrasound motion estimation.
(WILEY, 2016-08-01)PURPOSE: To quantify the performance of the Clarity ultrasound (US) imaging system (Elekta AB, Stockholm, Sweden) for real-time dynamic multileaf collimator (MLC) tracking. METHODS: The Clarity calibration and quality ... -
Five-fraction Radiotherapy for Breast Cancer: FAST-Forward to Implementation.
(ELSEVIER SCIENCE LONDON, 2023-05-19)INTRODUCTION: The phase 3 FAST-Forward trial reported outcomes for 26 and 27 Gy schedules delivered in 5 fractions over 1 week versus 40 Gy in 15 fractions over 3 weeks in 4000 patients. We discuss concerns raised by the ... -
Focal amplification of the androgen receptor gene in hormone-naive human prostate cancer
(NATURE PUBLISHING GROUP, 2014-03-18)Background: Androgen receptor (AR)-gene amplification, found in 20-30% of castration-resistant prostate cancer (CRPCa) is proposed to develop as a consequence of hormone-deprivation therapy and be a prime cause of treatment ... -
Focused ultrasound transducer spatial peak intensity estimation: a comparison of methods.
(2018-03-07)Characterisation of the spatial peak intensity at the focus of high intensity focused ultrasound transducers is difficult because of the risk of damage to hydrophone sensors at the high focal pressures generated. Hill et ... -

Focused Ultrasound-Mediated Hyperthermia in Vitro: An Experimental Arrangement for Treating Cells under Tissue-Mimicking Conditions.
(ELSEVIER SCIENCE INC, 2019-12-01)An experimental arrangement that allows in vitro exposure of cells to focused ultrasound-mediated hyperthermia (43°C-55°C) in a tissue-mimicking phantom with biological, acoustic and thermal properties comparable to those ... -
Four-dimensional imaging for radiotherapy planning in children and teenagers
(Institute of Cancer Research (University Of London), 2021-02-28)Respiratory-related organ motion (RROM) is a potential source of geometric uncertainty in RT planning and delivery. Approaches to mitigate its effects are well described in adults. For example, four-dimensional computed ... -
