The Impact of High-Dose-Rate Brachytherapy: Measuring Clinical Outcomes in the Primary Treatment of Cervical Cancer

Advances in Radiation Oncology, 2020
Purpose: Radical concurrent chemoradiotherapy with combined external beam radiotherapy (EBRT) and brachytherapy is used to treat locally advanced cervical cancer. Our institution has transitioned to high-dose-rate (HDR) intracavitary brachytherapy (ICBT)

Impact of rectal gas evacuation on dosimetry and applicator displacement in cervical cancer brachytherapy

Journal of Applied Clinical Medical Physics, Volume 27, Issue 2, February 2026.
Abstract Objective This study aimed to evaluate the impact of rectal gas evacuation on organ‐at‐risk (OAR) volumes, dose‐volume histogram (DVH) parameters, and applicator displacement during cervical cancer brachytherapy. Methods Twenty‐one cervical cancer patients who received three‐dimensional brachytherapy at our center between November and December

Functional outcomes and toxicity following focal low‐dose‐rate brachytherapy for low–intermediate risk prostate cancer

BJUI Compass, Volume 7, Issue 2, February 2026.
Abstract Objectives We aim to prospectively evaluate functional outcomes and toxicity following focal low‐dose‐rate (LDR) brachytherapy for low–intermediate risk prostate cancer (PCa). Patients and Methods LIBERATE is a clinical registry of men treated with focal LDR brachytherapy for low–intermediate risk PCa since September 2019.

A tandem reinforcement learning framework for localized prostate cancer treatment planning and machine parameter optimization

Medical Physics, Volume 53, Issue 2, February 2026.
Abstract Background Volumetric modulated arc therapy (VMAT) machine parameter optimization (MPO) is a complex, high‐dimensional problem typically solved with inverse planning solutions that are both temporally and computationally expensive. While machine learning techniques have been explored to automate this process, they often supplement rather than ...

Generation of 3D reference dosimetric datasets towards adoption of model‐based dose calculations for permanent implant prostate brachytherapy

Medical Physics, Volume 53, Issue 2, February 2026.
Abstract Purpose This work aims to create and validate a comprehensive set of test cases and 3D reference dosimetric datasets for model‐based dose calculation algorithms (MBDCAs) in permanent implant prostate brachytherapy. These test cases address the limits of the standard TG‐43 formalism towards improving dose evaluations in prostate cancer ...

Assessing dose contribution to pelvic lymph nodes in intracavitary brachytherapy for cervical cancer

Journal of Contemporary Brachytherapy, 2017
Purpose: In radical radiotherapy for cervical cancer, high-dose-rate (HDR) brachytherapy is commonly used after external beam radiation therapy (EBRT) to deliver a cumulative EQD2 of 80 to 90 Gy to the primary tumor.
