Reduced inter-observer and intra-observer delineation variation in esophageal cancer radiotherapy by use of fiducial markers.
(TAYLOR & FRANCIS LTD, 2019-06-03)Objective: Delineation variation of esophageal tumors remains a large source of geometric uncertainty. In the present study, we investigated the inter- and intra-observer variation in esophageal gross tumor volume (GTV) ... -
Refined histopathological predictors of BRCA1 and BRCA2 mutation status: a large-scale analysis of breast cancer characteristics from the BCAC, CIMBA, and ENIGMA consortia.
(BMC, 2014-12-23)INTRODUCTION: The distribution of histopathological features of invasive breast tumors in BRCA1 or BRCA2 germline mutation carriers differs from that of individuals with no known mutation. Histopathological features thus ... -

'Relationship between thermal dose and cell death for "rapid" ablative and "slow" hyperthermic heating'.
(TAYLOR & FRANCIS LTD, 2019-01-01)AIM: Thermal isoeffective dose (TID) has not been convincingly validated for application to predict biological effects from rapid thermal ablation (e.g., using >55 °C). This study compares the classical method of quantifying ... -
Relationship of Cisplatin-Related Adverse Health Outcomes With Disability and Unemployment Among Testicular Cancer Survivors.
(OXFORD UNIV PRESS, 2020-08-01)BACKGROUND: Few data exist on the relationship of cisplatin-related adverse health outcomes (AHOs) with disability, unemployment, and self-reported health (SRH) among testicular cancer survivors (TCS). METHODS: A total of ... -
Relationship of self-reported body size and shape with risk for prostate cancer: A UK case-control study.
(PUBLIC LIBRARY SCIENCE, 2020-09-17)INTRODUCTION: Previous evidence has suggested a relationship between male self-reported body size and the risk of developing prostate cancer. In this UK-wide case-control study, we have explored the possible association ... -
Relationships between rectal and perirectal doses and rectal bleeding or tenesmus in pooled voxel-based analysis of 3 randomised phase III trials.
(ELSEVIER IRELAND LTD, 2020-09-01)BACKGROUND AND PURPOSE: This study aimed to identify anatomically-localised regions where planned radiotherapy dose is associated with gastrointestinal toxicities in healthy tissues throughout the pelvic anatomy. MATERIALS ... -
Relative fat fraction of malignant bone lesions from breast cancer, prostate cancer and myeloma are significantly lower than normal bone marrow and shows excellent interobserver agreement.
(BRITISH INST RADIOLOGY, 2023-11-01)OBJECTIVES: To compare relative fat fraction (rFF) of active bone lesions from breast, prostate and myeloma malignancies and normal bone marrow; to assess its inter-reader agreement. METHODS: Patients with breast (n = 26), ... -
Reliability and prognostic value of radiomic features are highly dependent on choice of feature extraction platform.
(SPRINGER, 2020-11-01)OBJECTIVE: To investigate the effects of Image Biomarker Standardisation Initiative (IBSI) compliance, harmonisation of calculation settings and platform version on the statistical reliability of radiomic features and their ... -
Removing rician bias in diffusional kurtosis of the prostate using real-data reconstruction.
(WILEY, 2020-06-01)PURPOSE: To compare prostate diffusional kurtosis imaging (DKI) metrics generated using phase-corrected real data with those generated using magnitude data with and without noise compensation (NC). METHODS: Diffusion-weighted ... -
Reovirus-induced cell-mediated immunity for the treatment of multiple myeloma within the resistant bone marrow niche.
(BMJ PUBLISHING GROUP, 2021-01-01)BACKGROUND: Multiple myeloma (MM) remains an incurable disease and oncolytic viruses offer a well-tolerated addition to the therapeutic arsenal. Oncolytic reovirus has progressed to phase I clinical trials and its direct ... -
Repeatability and reproducibility of longitudinal relaxation rate in 12 small-animal MRI systems.
(ELSEVIER SCIENCE INC, 2019-06-01)BACKGROUND: Many translational MR biomarkers derive from measurements of the water proton longitudinal relaxation rate R1, but evidence for between-site reproducibility of R1 in small-animal MRI is lacking. OBJECTIVE: To ... -
Repeatability and sensitivity of T2* measurements in patients with head and neck squamous cell carcinoma at 3T.
(WILEY-BLACKWELL, 2016-07-01)PURPOSE: To determine whether quantitation of T2* is sufficiently repeatable and sensitive to detect clinically relevant oxygenation levels in head and neck squamous cell carcinoma (HNSCC) at 3T. MATERIALS AND METHODS: Ten ... -
Repeatability of derived parameters from histograms following non-Gaussian diffusion modelling of diffusion-weighted imaging in a paediatric oncological cohort.
(SPRINGER, 2017-01-01)OBJECTIVES: To examine repeatability of parameters derived from non-Gaussian diffusion models in data acquired in children with solid tumours. METHODS: Paediatric patients (<16 years, n = 17) were scanned twice, 24 h apart, ... -
Repeatability of quantitative individual lesion and total disease multiparametric whole-body MRI measurements in prostate cancer bone metastases.
(BRITISH INST RADIOLOGY, 2023-11-01)OBJECTIVES: To assess the repeatability of quantitative multiparametric whole-body MRI (mpWB-MRI) parameters in advanced prostate cancer (APC) bone metastases. METHODS: 1.5T MRI was performed twice on the same day in 10 ... -
