Approaches to Optimization of Dose in Radiation Therapy of Cervix Carcinoma

Abstract

A treatment planning approach to radiation therapy for women with carcinoma of the cervix which attempts to maximize tumor dose and minimize the effect on normal tissue must include additional dose reference points besides the standard ones (Manchester points A and B, mg-h). A variety of loading configurations can be used to treat the tumor volume to a specified dose. In order to avoid inappropriate loading arrangements, dose at the tumor and at the vault must be carried to required therapeutic levels.
