AbstractA prospective study with a newly designed schedule of concomitant chemoradiotherapy was initiated for 42 patients with previously untreated squamous cell carcinoma of the uterine cervix. Their ages ranged from 34 to 77 years, median 57 years. There were 13 FIGO stage IIB, 1 IIIA, 27 IIIB, and 1 IVA. Radiotherapy was administered using 1.8 Gy/day, 5 days a week, to the whole pelvis (50.4 Gy/28 fractions) with local boost if indicated. Intracavitary brachytherapy of 5 Gy for five times was delivered after 1-2 weeks of rest. The first 21 patients received concomitant chemotherapy of biweekly PEB regimen (100 mg/m2 etoposide + 50 mg/m2 cisplatin + 50 mg/m2 bleomycin) for two to three cycles during external irradiation. The chemotherapy for the latter 21 patients was modified to weekly PEBF (50 mg/m2 etoposide + 20 mg/m2 cisplatin + 10 mg/m2 bleomycin + 800 mg/m2 5-FU, mixed in normal saline, 24-hr continuous iv infusion) for five to six cycles. All except 1 patient achieved complete response (97.6%) and sustain so after a median follow-up time of 30 months. There were three relapses--one with persistent pelvic disease and two with distant metastasis. Two-year overall survival and disease-free survival rates were 97.6 and 92.9%, respectively. Myelosuppression was moderate but fully recovered. Other acute toxicities were tolerated except for 1 patient who encountered grade IV radiation colitis with cecum perforation and required surgery. As to late morbidity, the incidence of radiation proctitis was high (21.4%) but of a mild degree, with 1 patient needing repeated transfusion. One patient developed chronic cystitis with an acontractile bladder. Our preliminary results show that concomitant chemoradiotherapy for advanced cervical carcinoma is both feasible and effective with acceptable toxicities. Further follow-up is mandatory to ensure whether this high complete response protocol will translate into long-term local control and survival.
