Low dose rate brachytherapy in the treatment of cervical carcinoma.
The use of ICRT is a critical component in the successful treatment of cervical carcinoma with radiation therapy. Low dose rate ICRT allows optimization of the therapeutic ratio by utilizing physical and radiobiological principles. An optimal geometric relationship among the intracavitary applicators, the tumor, and other pelvic tissues is critically important in maximizing tumor control rates while simultaneously minimizing normal tissue complication rates. Treatment policies that have judiciously combined EBRT and LDR ICRT have achieved very high tumor control rates while maintaining acceptable complication rates. The use of HDR ICRT forfeits some of the radiobiological advantage of LDR ICRT. It remains to be determined whether this difference will have significant clinical consequences.
