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, 2020-07-01)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 ... -
The MRI-Linear Accelerator Consortium: Evidence-Based Clinical Introduction of an Innovation in Radiation Oncology Connecting Researchers, Methodology, Data Collection, Quality Assurance, and Technical Development.
(FRONTIERS MEDIA SA, 2016-10-13)An international research consortium has been formed to facilitate evidence-based introduction of MR-guided radiotherapy (MR-linac) and to address how the MR-linac could be used to achieve an optimized radiation treatment ... -
The National Institute for Health and Care Excellence (NICE) Guidance on Bladder Cancer; a Step in the Right Direction?
(ELSEVIER SCIENCE LONDON, 2017-06-01) -
The OncoArray Consortium: A Network for Understanding the Genetic Architecture of Common Cancers.
(AMER ASSOC CANCER RESEARCH, 2017-01-01)BACKGROUND: Common cancers develop through a multistep process often including inherited susceptibility. Collaboration among multiple institutions, and funding from multiple sources, has allowed the development of an ... -
The Patient Deficit Model Overturned: a qualitative study of patients' perceptions of invitation to participate in a randomized controlled trial comparing selective bladder preservation against surgery in muscle invasive bladder cancer (SPARE, CRUK/07/011).
(2012-11-29)Background Evidence suggests that poor recruitment into clinical trials rests on a patient 'deficit' model - an inability to comprehend trial processes. Poor communication has also been cited as a possible barrier to ... -
The PERK Inhibitor GSK2606414 Enhances Reovirus Infection in Head and Neck Squamous Cell Carcinoma via an ATF4-Dependent Mechanism.
(CELL PRESS, 2020-03-27)Reovirus type 3 Dearing (reovirus) is a tumor-selective oncolytic virus currently under evaluation in clinical trials. Here, we report that the therapeutic efficacy of reovirus in head and neck squamous cell cancer can be ... -
The potential of <sup>223</sup>Ra and <sup>18</sup>F-fluoride imaging to predict bone lesion response to treatment with <sup>223</sup>Ra-dichloride in castration-resistant prostate cancer.
(2017-10)Purpose The aims of this study were to calculate bone lesion absorbed doses resulting from a weight-based administration of 223 Ra-dichloride, to assess the relationship between those doses and corresponding 18 F-fluoride ... -
The potential role of MR-guided adaptive radiotherapy in pediatric oncology: Results from a SIOPE-COG survey.
Background and purpose Magnetic resonance guided radiotherapy (MRgRT) has been successfully implemented for several routine clinical applications in adult patients. The purpose of this study is to map the potential benefit ... -
The potential role of three-dimensional surface imaging as a tool to evaluate aesthetic outcome after Breast Conserving Therapy (BCT).
(WILEY, 2017-04-01)PURPOSE: To establish whether objective measurements of symmetry of volume and shape using three-dimensional surface imaging (3D-SI) can be used as surrogate markers of aesthetic outcome in patients who have undergone ... -
The predictive ability of the 313 variant-based polygenic risk score for contralateral breast cancer risk prediction in women of European ancestry with a heterozygous BRCA1 or BRCA2 pathogenic variant.
(ELSEVIER SCIENCE INC, 2021-06-10)PURPOSE: To evaluate the association between a previously published 313 variant-based breast cancer (BC) polygenic risk score (PRS313) and contralateral breast cancer (CBC) risk, in BRCA1 and BRCA2 pathogenic variant ... -
The predictive and prognostic value of tumour necrosis in muscle invasive bladder cancer patients receiving radiotherapy with or without chemotherapy in the BC2001 trial (CRUK/01/004).
(ELSEVIER SCI LTD, 2017-02-28)BACKGROUND: Severe chronic hypoxia is associated with tumour necrosis. In patients with muscle invasive bladder cancer (MIBC), necrosis is prognostic for survival following surgery or radiotherapy and predicts benefit from ... -
