Early Toxicities After High Dose Rate Proton Therapy in Cancer Treatments

Frontiers in Oncology, 2021
BackgroundThe conventional dose rate of radiation therapy is 0.01–0.05 Gy per second. According to preclinical studies, an increased dose rate may offer similar anti-tumoral effect while dramatically improving normal tissue protection. This study aims at

Monte Carlo study of radiation dose enhancement by gadolinium in megavoltage and high dose rate radiotherapy. [PDF]

PLoS ONE, 2014
MRI is often used in tumor localization for radiotherapy treatment planning, with gadolinium (Gd)-containing materials often introduced as a contrast agent. Motexafin gadolinium is a novel radiosensitizer currently being studied in clinical trials.
