The carbon footprint of external beam radiotherapy and its impact in health technology assessment.
Clin Transl Radiat Oncol

Article Synopsis
- The study evaluates the carbon footprint of external beam radiation therapy (EBRT) across four centers, identifying key factors that contribute to COeq emissions, such as treatment methods and patient transportation.
- Findings show that a typical EBRT treatment can emit between 185 kgCOeq and 2066 kgCOeq, with major contributors being accelerator maintenance, patient transportation, and medical supplies, along with notable variability between centers.
- Hypofractionation is highlighted as a significant strategy to reduce emissions, and incorporating COeq emissions into health technology assessments can positively influence the promotion of more environmentally friendly treatment regimens.
Introduction: The management of local relapse after prostate cancer radiotherapy is frequently based on androgen deprivation therapy. The aim of the study was to report Gustave Roussy's experience with salvage prostate brachytherapy.
Patients And Methods: All cases of localized prostate cancer presenting in an irradiated area who received salvage high dose rate (HDR) brachytherapy from 2013 to 2020 were retrospectively reviewed.
Article Synopsis
- - The study focuses on understanding how radiomic shape features from tumors correlate with patient outcomes and how these features are affected by tumor complexity, volume, and imaging methods.
- - Researchers created and 3D printed twenty-eight tumor models with varying levels of complexity, then analyzed images of these models using different algorithms to extract nine distinct 3D shape features.
- - The analysis involves comparing features extracted from directly printed models versus those computed from images, assessing the influence of factors like scan resolution and image processing on shape measurements.
