PURPOSE: Colposcopic response of preoperative uterine cervix carcinomas to intra-arterial cisplatin infusion chemotherapy was analyzed to evaluate the efficacy of this therapy after selective pelvic arteriography. MATERIALS AND METHODS: Nine patients of stage 1/11 cervical carcinomas were treated twice with intra-arterial cisplatin chemotherapy of a 3-week interval, with every week follow-up of colposcopy and histology until the radical hysterectomy and pelvic lymphadenectomy on the 6th week. Cisplatin of 50mg/m~ was slowly infused via autoinjector for 10 minutes with the catheter tip placed in both internal iliac arteries around uterine artery branching. RESULTS: Colposcopic regression rate of tumor size was as follows:more than 2/3 decrease of original size in 2 patients, 2/3-1/2 in 2 patients, less than 1/2 in 4 patients, but in one patient minimal increase in tumor size was recognized. Colposcopic and postoperative microscopic pathology revealed degeneration and necrosis of the tumor cells and/or adjacent lymph nodes and fibrosis of surrounding tissues. All patients have been doing well until postoperative 25 months without recurrence or significant complications. CONCLUSION: Preoperative intra-arterial cisplatin chemotherapy after selective internal iliac rteriography is helpful to decrease tumor size and improve histologic response and prognosis in stage I and II cervical carcinomas.
