Radiographer-led online image guided adaptive radiotherapy: A qualitative investigation of the therapeutic radiographer role.
(ELSEVIER SCI LTD, 2021-05-15)INTRODUCTION: Online MRI guided adaptive radiotherapy (MRIgRT) is resource intensive. To maintain and increase uptake traditional roles and responsibilities may need refining. This novel study aims to provide an in-depth ... -
Radiographic progression with nonrising PSA in metastatic castration-resistant prostate cancer: post hoc analysis of PREVAIL.
(NATURE PUBLISHING GROUP, 2017-06-01)BACKGROUND: Advanced prostate cancer is a phenotypically diverse disease that evolves through multiple clinical courses. PSA level is the most widely used parameter for disease monitoring, but it has well-recognized ... -
Radiological Biomarkers in MRI directed Rectal Cancer Radiotherapy Volume Delineation.
(MDPI, 2023-10-27)Our study evaluated whether an MRI reporting system highlighting areas of contiguous and discontinuous extramural venous invasion (EMVI) can improve the accuracy of gross tumour volume (GTV) delineation. Initially, 27 ... -
Radiological evaluation of malignant pleural mesothelioma - defining distant metastatic disease.
(BMC, 2020-12-09)BACKGROUND: Malignant pleural mesothelioma (MPM) is traditionally characterized by local destructive spread of the pleura and surrounding tissues. Patient outcomes in MPM with distant metastatic dissemination are lacking. ... -
Radiological Evaluation of Newly Diagnosed Non-Brainstem Pediatric High-Grade Glioma in the HERBY Phase II Trial.
(AMER ASSOC CANCER RESEARCH, 2020-04-15)PURPOSE: The HERBY trial evaluated the benefit of the addition of the antiangiogenic agent Bevacizumab (BEV) to radiotherapy/temozolomide (RT/TMZ) in pediatric patients with newly diagnosed non-brainstem high-grade glioma ... -
Radiological Patterns of Drug-induced Interstitial Lung Disease (DILD) in Early-phase Oncology Clinical Trials.
(AMER ASSOC CANCER RESEARCH, 2020-09-15)PURPOSE: Drug-induced interstitial lung disease (DILD) is a rare, but potentially fatal toxicity. Clinical and radiological features of DILD in the early experimental setting are poorly described. PATIENTS AND METHODS: A ... -
Radiomic Features From Diffusion-Weighted MRI of Retroperitoneal Soft-Tissue Sarcomas Are Repeatable and Exhibit Change After Radiotherapy.
(FRONTIERS MEDIA SA, 2022-07-18)BACKGROUND: Size-based assessments are inaccurate indicators of tumor response in soft-tissue sarcoma (STS), motivating the requirement for new response imaging biomarkers for this rare and heterogeneous disease. In this ... -
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 ... -
Radiomics as a personalized medicine tool in lung cancer: Separating the hope from the hype.
(ELSEVIER IRELAND LTD, 2020-08-01)Radiomics has become a popular image analysis method in the last few years. Its key hypothesis is that medical images harbor biological, prognostic and predictive information that is not revealed upon visual inspection. ... -
A radiomics-based decision support tool improves lung cancer diagnosis in combination with the Herder score in large lung nodules.
(ELSEVIER, 2022-12-01)BACKGROUND: Large lung nodules (≥15 mm) have the highest risk of malignancy, and may exhibit important differences in phenotypic or clinical characteristics to their smaller counterparts. Existing risk models do not stratify ... -
Radiosensitization by the ATR Inhibitor AZD6738 through Generation of Acentric Micronuclei.
(AMER ASSOC CANCER RESEARCH, 2017-01-01)AZD6738 is an orally active ATR inhibitor (ATRi) currently in phase I clinical trials. We found in vitro growth inhibitory activity of this ATRi in a panel of human cancer cell lines. We demonstrated radiosensitization by ... -
Radiosynthesis of the anticancer nucleoside analogue Trifluridine using an automated 18F-trifluoromethylation procedure.
(ROYAL SOC CHEMISTRY, 2018-04-25)Trifluoromethyl groups are widespread in medicinal chemistry, yet there are limited 18F-radiochemistry techniques available for the production of the complementary PET agents. Herein, we report the first radiosynthesis of ... -
Radiotherapy dose-distribution to the perirectal fat space (PRS) is related to gastrointestinal control-related complications.
(2017-12)Traditionally rectal symptoms following pelvic/prostate radiotherapy are correlated to the dosimetry of the anorectum or a substructure of this. It has been suggested that the perirectal fat space (PRS) surrounding the ... -
Radiotherapy enhances responses of lung cancer to CTLA-4 blockade.
(BMC, 2019-03-06)Formenti et al. have recently reported the clinical outcomes and translational readouts of a trial of the anti-CTLA-4 inhibitor, ipilimumab, in combination with palliative radiotherapy in 39 patients with non-small cell ... -
Radiotherapy in Dupuytren's disease: a systematic review of the evidence.
(2017-09)Radiotherapy has been advocated as an alternative treatment in early Dupuytren's disease. We have systematically reviewed the evidence on the use of radiotherapy in Dupuytren's disease. Only six articles met a minimum set ... -
Radiotherapy plus cisplatin or cetuximab in low-risk human papillomavirus-positive oropharyngeal cancer (De-ESCALaTE HPV): an open-label randomised controlled phase 3 trial.
