The effect of sample size on polygenic hazard models for prostate cancer.
(SPRINGERNATURE, 2020-10-01)We determined the effect of sample size on performance of polygenic hazard score (PHS) models in prostate cancer. Age and genotypes were obtained for 40,861 men from the PRACTICAL consortium. The dataset included 201,590 ... -
The effects of oncolytic Maraba virus (MG1) in advanced non-small cell lung cancer
(Institute of Cancer Research (University Of London), 2021-08-31)Lung cancer is responsible for the highest cancer mortality worldwide. The prognosis for patients with advanced disease remains poor with five-year overall survival of <10%, highlighting the urgent unmet need for novel ... -
The Effects of Spectral X-Ray Photon Counting Detector Parameters on Detector Performance: Thickness and Pitch

The emerging potential of magnetic resonance imaging in personalizing radiotherapy for head and neck cancer: an oncologist's perspective.
(BRITISH INST RADIOLOGY, 2017-01-01)Head and neck cancer (HNC) is a challenging tumour site for radiotherapy delivery owing to its complex anatomy and proximity to organs at risk (OARs) such as the spinal cord and optic apparatus. Despite significant advances ... -
The Feasibility of Thermal Imaging as a Future Portal Imaging Device for Therapeutic Ultrasound.
(ELSEVIER SCIENCE INC, 2016-08-01)This technical note describes a prototype thermally based portal imaging device that allows mapping of energy deposition on the surface of a tissue mimicking material in a focused ultrasound surgery (FUS) beam by using an ... -
The genomic landscape of testicular germ cell tumours: from susceptibility to treatment.
(NATURE PUBLISHING GROUP, 2016-07-01)The genomic landscape of testicular germ cell tumour (TGCT) can be summarized using four overarching hypotheses. Firstly, TGCT risk is dominated by inherited genetic factors, which determine nearly half of all disease risk ... -
The Immunogenic Potential of Recurrent Cancer Drug Resistance Mutations: An In Silico Study.
(FRONTIERS MEDIA SA, 2020-10-08)Cancer somatic mutations have been identified as a source of antigens that can be targeted by cancer immunotherapy. In this work, expanding on previous studies, we analyze the HLA-presentation properties of mutations that ... -
The immunological consequences of radiation-induced DNA damage.
(WILEY, 2019-04-01)Historically, our understanding of the cytotoxicity of radiation has centred on tumour cell-autonomous mechanisms of cell death. Here, tumour cell death occurs when a threshold number of radiation-induced non-reparable ... -
The impact of 2D cine MR imaging parameters on automated tumor and organ localization for MR-guided real-time adaptive radiotherapy.
(IOP PUBLISHING LTD, 2018-11-22)2D cine MR imaging may be utilized to monitor rapidly moving tumors and organs-at-risk for real-time adaptive radiotherapy. This study systematically investigates the impact of geometric imaging parameters on the ability ... -
The Impact of Optimal Respiratory Gating and Image Noise on Evaluation of Intratumor Heterogeneity on 18F-FDG PET Imaging of Lung Cancer.
(2016-11)Accurate measurement of intratumor heterogeneity using parameters of texture on PET images is essential for precise characterization of cancer lesions. In this study, we investigated the influence of respiratory motion and ... -
The impact of restricted length of treatment field and anthropometric factors on selection of head and neck cancer patients for treatment on the MR-Linac.
(BRITISH INST RADIOLOGY, 2020-01-01)OBJECTIVE: This study investigates the impact of a restricted craniocaudal (CC) field length of <20 cm on the selection of head and neck cancer (HNC) patients who can be treated on the MR-Linac using a single isocentre ... -
The Intensity-Modulated Pelvic Node and Bladder Radiotherapy (IMPART) Trial: A Phase II Single-Centre Prospective Study.
(ELSEVIER SCIENCE LONDON, 2020-02-01)AIMS: Node-positive bladder cancer (NPBC) carries a poor prognosis and has traditionally been treated palliatively. However, surgical series suggest that a subset of NPBC patients can achieve long-term control after ... -
The melanoma-specific graded prognostic assessment does not adequately discriminate prognosis in a modern population with brain metastases from malignant melanoma.
(NATURE PUBLISHING GROUP, 2015-11-03)BACKGROUND: The melanoma-specific graded prognostic assessment (msGPA) assigns patients with brain metastases from malignant melanoma to 1 of 4 prognostic groups. It was largely derived using clinical data from patients ... -
The MOMENTUM Study: An International Registry for the Evidence-Based Introduction of MR-Guided Adaptive Therapy.
(FRONTIERS MEDIA SA, 2020-09-07)Purpose: MR-guided Radiation Therapy (MRgRT) allows for high-precision radiotherapy under real-time MR visualization. This enables margin reduction and subsequent dose escalation which may lead to higher tumor control and ... -
