Abstract

In brachytherapy of uterine cervical cancer using a high dose rate remote afterloading system, it is of prime importance to deliver a accurate dose in each fractionated treatment by minimizing the difference between the pre-treatment planned and post-treatment calculated doses. The post-treatment calculated point A dose was not much different from the pretreatment planned dose (500 cGy). The average+/-standard deviation was 500+/-18 cGy and 84 percent of 82 intracavitary radiotherapy was within the range of 500+/-25 cGy.
