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 ... -
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.
(ELSEVIER SCIENCE INC, 2019-01-05)BACKGROUND: The incidence of human papillomavirus (HPV)-positive oropharyngeal cancer, a disease affecting younger patients, is rapidly increasing. Cetuximab, an epidermal growth factor receptor inhibitor, has been proposed ... -
Radiotherapy Quality Assurance for the CHHiP Trial: Conventional Versus Hypofractionated High-Dose Intensity-Modulated Radiotherapy in Prostate Cancer.
(ELSEVIER SCIENCE LONDON, 2019-09)AIMS: The CHHiP trial investigated the use of moderate hypofractionation for the treatment of localised prostate cancer using intensity-modulated radiotherapy (IMRT). A radiotherapy quality assurance programme was developed ... -
Radiotherapy to the primary tumour for newly diagnosed, metastatic prostate cancer (STAMPEDE): a randomised controlled phase 3 trial.
(ELSEVIER SCIENCE INC, 2018-12-01)BACKGROUND: Based on previous findings, we hypothesised that radiotherapy to the prostate would improve overall survival in men with metastatic prostate cancer, and that the benefit would be greatest in patients with a low ... -
Radiotherapy to the prostate for men with metastatic prostate cancer in the UK and Switzerland: Long-term results from the STAMPEDE randomised controlled trial.
(PUBLIC LIBRARY SCIENCE, 2022-06-01)BACKGROUND: STAMPEDE has previously reported that radiotherapy (RT) to the prostate improved overall survival (OS) for patients with newly diagnosed prostate cancer with low metastatic burden, but not those with high-burden ... -
Randomized controlled trial of dietary fiber for the prevention of radiation-induced gastrointestinal toxicity during pelvic radiotherapy.
(OXFORD UNIV PRESS, 2017-09-01)Background: Therapeutic radiotherapy is an important treatment of pelvic cancers. Historically, low-fiber diets have been recommended despite a lack of evidence and potentially beneficial mechanisms of fiber.Objective: ... -
Randomized Phase II Study Investigating Pazopanib Versus Weekly Paclitaxel in Relapsed or Progressive Urothelial Cancer.
(AMER SOC CLINICAL ONCOLOGY, 2017-06-01)Purpose Two previous single-arm trials have drawn conflicting conclusions regarding the activity of pazopanib in urothelial cancers after failure of platinum-based chemotherapy. Patients and Methods This randomized (1:1) ... -
