Workflow to detect exceeded dose constraints in pancreatic stereotactic body irradiation after intrafraction motion during magnetic resonance-guided adaptive radiotherapy using a deep learning-refined contour propagation tool

Physics and Imaging in Radiation Oncology
Introduction: The adapt-to-shape (ATS) process on the MR-Linac involves manual contour edits followed by treatment plan re-optimization on daily pre-beam MRIs.

Medical image computing and computer-aided medical interventions applied to soft tissues. Work in progress in urology

, 2006
Until recently, Computer-Aided Medical Interventions (CAMI) and Medical Robotics have focused on rigid and non deformable anatomical structures. Nowadays, special attention is paid to soft tissues, raising complex issues due to their mobility and ...

Trends in the incidence of cancers of the breast and female genital tract in Harare, Zimbabwe 1990–2019

International Journal of Cancer, EarlyView.
What's New? Cancers of the breast and female genital tract represent more than half of all cancers in women in sub‐Saharan Africa. Here, the authors assessed incidence trends in a female population living in urban sub‐Saharan Africa based on the Zimbabwe National Cancer Registry in Harare over a 30‐year period.

The impact of rectal spacers in MR-guided adaptive radiotherapy

Clinical and Translational Radiation Oncology
The use of stereotactic ablative radiotherapy (SABR) for prostate cancer has increased significantly. However, SABR can elevate the risk of moderate gastrointestinal (GI) side effects. Rectal spacers mitigate this risk by reducing the rectal dose. This study evaluates the impact of rectal spacers in MR-guided adaptive radiotherapy (MRgART) for prostate

Comparison of prostate delineation on multimodality imaging for MR-guided radiotherapy

The British Journal of Radiology, 2019
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 individually on CT, T  2 weighted (T  2W) and T  2* weighted (T  2*W) imaging for 10 patients.

Effect of Interval Between Neoadjuvant Immunochemotherapy and Radical Resection of Non‐Small Cell Lung Cancer: A Multicenter, Retrospective Cohort Study

International Journal of Cancer, EarlyView.
The optimal timing of surgery after neoadjuvant immunochemotherapy (NICT) for locally advanced non‐small cell lung cancer (NSCLC) remains unclear. In this retrospective investigation, the impact of time interval on outcome was assessed among NSCLC patients who completed NICT before undergoing radical resection.

Dosimetric evidence confirms computational model for magnetic field induced dose distortions of therapeutic proton beams

, 2017
Given the sensitivity of proton therapy to anatomical variations, this cancer treatment modality is expected to benefit greatly from integration with magnetic resonance (MR) imaging.

Evaluating the Impact of Age on Prostate Cancer Overdiagnosis Using Long‐Term Follow‐Up From the CAP Randomised Trial

International Journal of Cancer, EarlyView.
Uncertainty persists over whether the benefits of prostate‐specific antigen (PSA) screening outweigh harms from overdiagnosis, a key barrier to population‐wide adoption. Here, English male mortality rates were analyzed alongside long‐term data from the UK Cluster Randomized Trial of PSA Testing for Prostate Cancer (CAP) to estimate age‐specific ...
