Patients choose certainty over burden in bladder cancer surveillance.
(SPRINGER, 2019-12-01)BACKGROUND: Due to the high risk of recurrence of non-muscle invasive bladder cancer, all patients undergo regular cystoscopic surveillance for early detection. As cystoscopy is invasive, costly and increases the burden ... -
Polygenic risk-tailored screening for prostate cancer: A benefit-harm and cost-effectiveness modelling study.
(PUBLIC LIBRARY SCIENCE, 2019-12-01)BACKGROUND: The United States Preventive Services Task Force supports individualised decision-making for prostate-specific antigen (PSA)-based screening in men aged 55-69. Knowing how the potential benefits and harms of ... -
Abiraterone in "High-" and "Low-risk" Metastatic Hormone-sensitive Prostate Cancer.
(ELSEVIER, 2019-12-01)BACKGROUND: Abiraterone acetate received licencing for use in only "high-risk" metastatic hormone-naïve prostate cancer (mHNPC) following the LATITUDE trial findings. However, a "risk"-related effect was not seen in the ... -
RTT-led IGRT for cervix cancer; training, implementation and validation.
(Elsevier BV, 2019-12-16)INTRODUCTION: IGRT in cervical cancer treatment delivery is complex due to significant target and organs at risk (OAR) motion. Implementing image assessment of soft-tissue target and OAR position to improve accuracy is ... -
Magnetic resonance imaging sequence evaluation of an MR Linac system; early clinical experience.
(Elsevier BV, 2019-12-16)OBJECTIVES: To systematically identify the preferred magnetic resonance imaging (MRI) sequences following volunteer imaging on a 1.5 Tesla (T) MR-Linear Accelerator (MR Linac) for future protocol development. METHODS: ... -
Adult soft tissue myoepithelial carcinoma: treatment outcomes and efficacy of chemotherapy.
(OXFORD UNIV PRESS, 2019-12-27)Soft tissue myoepithelial carcinomas are a rare, malignant subgroup of myoepithelial tumours mostly arising in the extremities with equal predilection for women and men. The mainstay of management of localised disease is ... -
Deep learning how to fit an intravoxel incoherent motion model to diffusion-weighted MRI.
(WILEY, 2020-01-01)PURPOSE: This prospective clinical study assesses the feasibility of training a deep neural network (DNN) for intravoxel incoherent motion (IVIM) model fitting to diffusion-weighted MRI (DW-MRI) data and evaluates its ... -
Prostate Cancer Risks for Male BRCA1 and BRCA2 Mutation Carriers: A Prospective Cohort Study.
(ELSEVIER, 2020-01-01)BACKGROUND: BRCA1 and BRCA2 mutations have been associated with prostate cancer (PCa) risk but a wide range of risk estimates have been reported that are based on retrospective studies. OBJECTIVE: To estimate relative and ... -
Current challenges for assessing the long-term clinical benefit of cancer immunotherapy: a multi-stakeholder perspective.
(BMJ PUBLISHING GROUP, 2020-01-01)Immuno-oncologics (IOs) differ from chemotherapies as they prime the patient's immune system to attack the tumor, rather than directly destroying cancer cells. The IO mechanism of action leads to durable responses and ... -
Consensus guidelines for the definition, detection and interpretation of immunogenic cell death.
(BMJ PUBLISHING GROUP, 2020-01-01)Cells succumbing to stress via regulated cell death (RCD) can initiate an adaptive immune response associated with immunological memory, provided they display sufficient antigenicity and adjuvanticity. Moreover, multiple ... -
Radiomic features of cervical cancer on T2-and diffusion-weighted MRI: Prognostic value in low-volume tumors suitable for trachelectomy.
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2020-01-01)BACKGROUND: Textural features extracted from MRI potentially provide prognostic information additional to volume for influencing surgical management of cervical cancer. PURPOSE: To identify textural features that differ ... -
Characterisation and classification of oligometastatic disease: a European Society for Radiotherapy and Oncology and European Organisation for Research and Treatment of Cancer consensus recommendation.
(ELSEVIER SCIENCE INC, 2020-01-01)Oligometastatic disease has been proposed as an intermediate state between localised and systemically metastasised disease. In the absence of randomised phase 3 trials, early clinical studies show improved survival when ... -
The Effects of Spectral X-Ray Photon Counting Detector Parameters on Detector Performance: Thickness and Pitch
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2020-01-01) -
Combining BRAF inhibition with oncolytic herpes simplex virus enhances the immune-mediated antitumor therapy of BRAF-mutant thyroid cancer.
(BMJ PUBLISHING GROUP, 2020-01-01)BACKGROUND: The aggressive clinical behavior of poorly differentiated and anaplastic thyroid cancers (PDTC and ATC) has proven challenging to treat, and survival beyond a few months from diagnosis is rare. Although 30%-60% ... -
Prediction of pelvic tumour coverage by magnetic resonance-guided high-intensity focused ultrasound (MRgHIFU) from referral imaging.
(TAYLOR & FRANCIS LTD, 2020-01-01)BACKGROUND: Patient suitability for magnetic resonance-guided high intensity focused ultrasound (MRgHIFU) ablation of pelvic tumors is initially evaluated clinically for treatment feasibility using referral images, acquired ... -
A randomised assessment of image guided radiotherapy within a phase 3 trial of conventional or hypofractionated high dose intensity modulated radiotherapy for prostate cancer.
(ELSEVIER IRELAND LTD, 2020-01-01)BACKGROUND AND PURPOSE: Image-guided radiotherapy (IGRT) improves treatment set-up accuracy and provides the opportunity to reduce target volume margins. We introduced IGRT methods using standard (IGRT-S) or reduced (IGRT-R) ... -
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 ... -
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 ... -
