Tumor marker and MR imaging criteria for evaluating the efficacy of cyclic balloon-occluded arterial infusion for advanced cancer of the uterine cervix.

We have already reported satisfactory therapeutic results of cisplatin-based cyclic balloon-occluded arterial infusion chemotherapy (BOAI) enabling treatment by simple total hysterectomy (STH) in patients with advanced cervical cancer of the uterus (cervical cancer), with 2- and 5-year survival rates of 88.9% and 66. 7%, respectively. Considering the fact that 3 to 4 months are needed to complete BOAI, the present study was a retrospective assessment of 18 cervical cancer patients to prepare criteria for the early determination of the efficacy of BOAI in patients who can be treated by STH. The results showed that STH could be performed after the first BOAI in patients with SCC value decreased to 34.3+/-8.2% of the pretreatment value (p=0.0001) and whose tumor size had decreased by 45.1+/-7.5% (p=0.0002).
