Radiobiological qualitative evaluation of high dose rate intracavitary brachytherapy for gynecological cancers.

Dr. Pranabandhu Das, S. Manimaran

Abstract :

The purpose of this study is to evaluate quality of high dose rate (HDR) intracavitary brachytherapy by adopting figure of merit (FOM) concept. The data of twenty patient�s dose to the critical organ was evaluated; an ideal intracavitary application must have FOM value close to ten. FOM value higher or lower than ten correspond to treatments, which overall are likely to greater or lesser than reference. a graph has been plotted to extract abnormal values. FOM values are evaluated for all patients, we found all scored below tolerance value, but two patients scored more than tolerance value for rectum, in case of bladder one patient scored greater value.
