Comparison of prostate delineation on multimodality imaging for MR-guided radiotherapy.
(BRITISH INST RADIOLOGY, 2019-03-01)
OBJECTIVE:: With increasing incorporation of MRI in radiotherapy, we investigate two MRI sequences for prostate delineation in radiographer-led image guidance. METHODS:: Five therapeutic radiographers contoured the prostate ...
Realizing the potential of magnetic resonance image guided radiotherapy in gynaecological and rectal cancer.
(BRITISH INST RADIOLOGY, 2019-05-14)
CT-based radiotherapy workflow is limited by poor soft tissue definition in the pelvis and reliance on rigid registration methods. Current image-guided radiotherapy and adaptive radiotherapy models therefore have limited ...
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 ...
In-vivo EPID dosimetry for IMRT and VMAT based on through-air predicted portal dose algorithm.
(ELSEVIER SCI LTD, 2018-08-01)
We have adapted the methodology of Berry et al. (2012) for Intensity Modulated Radiotherapy (IMRT) and Volumetric Modulated Arc Therapy (VMAT) treatments at a fixed source to imager distance (SID) based on the manufacturer's ...
Plane wave versus focused transmissions for contrast enhanced ultrasound imaging: the role of parameter settings and the effects of flow rate on contrast measurements.
(IOP PUBLISHING LTD, 2019-04-23)
Contrast enhanced ultrasound (CEUS) and dynamic contrast enhanced ultrasound (DCE-US) can be used to provide information about the vasculature aiding diagnosis and monitoring of a number of pathologies including cancer. ...
Improving fiducial and prostate capsule visualization for radiotherapy planning using MRI.
(WILEY, 2019-03-01)
BACKGROUND AND PURPOSE: Intraprostatic fiducial markers (FM) improve the accuracy of radiotherapy (RT) delivery. Here we assess geometric integrity and contouring consistency using a T2*-weighted (T2*W) sequence alone, ...
Impact of antibiotic use during curative treatment of locally advanced head and neck cancers with chemotherapy and radiotherapy.
(ELSEVIER SCI LTD, 2020-05-01)
BACKGROUND: Pre-clinical evidence suggests reduced efficacy of anticancer treatment in patients exposed to broad-spectrum antibiotics. It is hypothesised that this phenomenon may be explained by the effects of antibiotics ...
Genomic landscape of platinum resistant and sensitive testicular cancers.
(NATURE PUBLISHING GROUP, 2020-05-04)
While most testicular germ cell tumours (TGCTs) exhibit exquisite sensitivity to platinum chemotherapy, ~10% are platinum resistant. To gain insight into the underlying mechanisms, we undertake whole exome sequencing and ...
Noninvasive MRI Native T1 Mapping Detects Response to MYCN-targeted Therapies in the Th-MYCN Model of Neuroblastoma.
(AMER ASSOC CANCER RESEARCH, 2020-08-15)
Noninvasive early indicators of treatment response are crucial to the successful delivery of precision medicine in children with cancer. Neuroblastoma is a common solid tumor of young children that arises from anomalies ...
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 ...
