Distortion correction of echo-planar diffusion-weighted images of uterine cervix.
(WILEY-BLACKWELL, 2016-05-01)PURPOSE: To investigate the clinical utility of the reverse gradient algorithm in correcting distortions in diffusion-weighted images of the cervix and for increasing diagnostic performance. MATERIALS AND METHODS: Forty-one ... -
DNA-Repair Defects and Olaparib in Metastatic Prostate Cancer.
(MASSACHUSETTS MEDICAL SOC, 2015-10-29)BACKGROUND: Prostate cancer is a heterogeneous disease, but current treatments are not based on molecular stratification. We hypothesized that metastatic, castration-resistant prostate cancers with DNA-repair defects would ... -
Do imaging biomarkers relate to outcome in patients treated with VEGF inhibitors?
(AMER ASSOC CANCER RESEARCH, 2012-12-15)The management of solid tumors has been transformed by the advent of VEGF pathway inhibitors. Early clinical evaluation of these drugs has used pharmacodynamic biomarkers derived from advanced imaging such as dynamic MRI, ... -
Do traditional risk stratification models for cerebrovascular events apply in irradiated head and neck cancer patients?
(ELSEVIER SCI LTD, 2015-09-01)BACKGROUND: Primary radical radiotherapy (RT) for head and neck cancer (HNC) often results in significant radiation dose to the carotid arteries. AIM: We assessed whether HNC patients are at increased risk of a cerebrovascular ... -
Docetaxel for Nonmetastatic Prostate Cancer: Long-Term Survival Outcomes in the STAMPEDE Randomized Controlled Trial.
(OXFORD UNIV PRESS, 2022-07-01)BACKGROUND: STAMPEDE previously reported adding upfront docetaxel improved overall survival for prostate cancer patients starting long-term androgen deprivation therapy. We report long-term results for non-metastatic ... -
Does breast composition influence late adverse effects in breast radiotherapy?
(CHURCHILL LIVINGSTONE, 2016-04-01)BACKGROUND: Large breast size is associated with increased risk of late adverse effects after surgery and radiotherapy for early breast cancer. It is hypothesised that effects of radiotherapy on adipose tissue are responsible ... -
Dose prescription with spatial uncertainty for peripheral lung SBRT.
(2019-01)Current clinical practice is to prescribe to 95% of the planning target volume (PTV) in 4D stereotactic body radiotherapy (SBRT) for lung. Frequently the PTV margin has a very low physical density so that the internal ... -
Dose Reduction of Preoperative Radiotherapy in Myxoid Liposarcoma: A Nonrandomized Controlled Trial.
(2021-01-21)Importance Currently, preoperative radiotherapy for all soft-tissue sarcomas is identical at a 50-Gy dose level, which can be associated with morbidity, particularly wound complications. The observed clinical radiosensitivity ... -
Dose verification of dynamic MLC-tracked radiotherapy using small PRESAGE (R) 3D dosimeters and a motion phantom
(IOP PUBLISHING LTD, 2019-01-01) -
Dose-limiting Urinary Toxicity With Pembrolizumab Combined With Weekly Hypofractionated Radiation Therapy in Bladder Cancer.
(ELSEVIER SCIENCE INC, 2018-08-01)There is currently significant interest in the potential benefits of combining radiation and immune checkpoint blockade (ICB) to stimulate both regional and distant abscopal immune responses. In melanoma and lung cancer, ... -
Dosimetric accuracy of delivering SBRT using dynamic arcs on Cyberknife.
(WILEY, 2020-04-01)PURPOSE: Several studies have demonstrated potential improvements in treatment time through the use of dynamic arcs for delivery of stereotactic body radiation therapy (SBRT) on Cyberknife. However, the delivery system has ... -
Dosimetric accuracy of dynamic couch rotation during volumetric modulated arc therapy (DCR-VMAT) for primary brain tumours.
(IOP PUBLISHING LTD, 2019-04-05)Radiotherapy treatment plans using dynamic couch rotation during volumetric modulated arc therapy (DCR-VMAT) reduce the dose to organs at risk (OARs) compared to coplanar VMAT, while maintaining the dose to the planning ... -
Dosimetric comparison of automatically propagated prostate contours with manually drawn contours in MRI-guided radiotherapy: A step towards a contouring free workflow?
(ELSEVIER IRELAND LTD, 2022-11-01)BACKGROUND: The prostate demonstrates inter- and intra- fractional changes and thus adaptive radiotherapy would be required to ensure optimal coverage. Daily adaptive radiotherapy for MRI-guided radiotherapy can be both ... -
Dosimetric Implications of Computerised Tomography-Only versus Magnetic Resonance-Fusion Contouring in Stereotactic Body Radiotherapy for Prostate Cancer.
(MDPI AG, 2018-04-05)Background: Magnetic resonance (MR)-fusion contouring is the standard of care in prostate stereotactic body radiotherapy (SBRT) for target volume localisation. However, the planning computerised tomography (CT) scan continues ... -
Dosimetry and Gastrointestinal Toxicity Relationships in a Phase II Trial of Pelvic Lymph Node Radiotherapy in Advanced Localised Prostate Cancer.
(ELSEVIER SCIENCE LONDON, 2019-06-01)AIMS: Pelvic lymph node (PLN) radiotherapy for high-risk prostate cancer is limited by late gastrointestinal toxicity. Application of rectal and bowel constraints may reduce risks of side-effects. We evaluated associations ... -
Dosimetry-based treatment for Graves' disease.
(2018-06)Objective The aim of this retrospective study was to assess the long-term outcome of a personalized dosimetry approach in Graves' disease aiming to render patients euthyroid from a planned thyroid absorbed dose of ... -
Dosimetry-based treatment planning for molecular radiotherapy: a summary of the 2017 report from the Internal Dosimetry Task Force.
(2017-11-21)BACKGROUND:The European directive on basic safety standards (Council directive 2013/59 Euratom) mandates dosimetry-based treatment planning for radiopharmaceutical therapies. The directive comes into operation February ... -
Drug delivery across the blood-brain barrier using short-pulse focused ultrasound and microbubbles for the treatment of diffuse intrinsic pontine glioma
(Institute of Cancer Research (University Of London), 2023-09-01)The blood-brain barrier (BBB) prevents unwanted substances from entering the brain, but also blocks entry of therapeutic agents, posing difficulties for treating brain cancers such as diffuse intrinsic pontine glioma (DIPG) ... -
