    Abstract:
    PURPOSE: This is a prospective study to evaluate toxicity and efficacy of concurrent irradiation and three cycles of chemotherapy bolus cisplatin and infusion 5-fluorouracil (5FU) in patients with advanced gynecologic malignancies. MATERIALS AND METHODS: Patients received cisplatin, 50 mg/m2 I.V. rapid infusion, and 5-day continuous infusion of 5FU (750 mg/m2 per day (schedule A); or cisplatin 75 mg/m2 i.v. rapid infusion, and 4-day continuous infusion of 5FU 1,000 mg/m2 per day (schedule B). Schedule A was given to 25 patients in the first 36 months of the study and was changed to schedule B in an additional 42 patients. All patients received irradiation, which usually consisted of 20 Gy whole pelvis, 30-40 Gy split field, and two intracavitary insertions for a total of 80-90 Gy to point A. Primary cervical cancer occurred in 40 patients with 3 having stage IB bulky, 2 with stage IIA, 5 with stage IIB, 2 with stage IIIA, 23 with stage IIIB, 4 with stage IV, and 1 with stage IVB. Recurrent cervical carcinoma after radical hysterectomy occurred in 18 patients. The remainder of the patients consisted of two each with stages III and IV endometrial carcinoma, two with stage III vaginal carcinoma, two with stage III vulvar carcinoma, and one with recurrent vulvar carcinoma. Patients were treated from 1985 through 1992. RESULTS: The 5-year overall survivals for patients with stages IB (bulky)-IIB cervical cancer was 70%, 25% for stages IIIA-IVA, and 39% for patients with recurrent cervical carcinoma. All four patients with endometrial carcinoma have recurred and died. Two patients with vulvar carcinoma are alive and free of disease, and one is dead of intercurrent disease. One patient with stage III vaginal carcinoma is alive and free of disease, while the other recurred and died. No significant differences were observed in the toxicity of the two chemotherapy schedules. There were 9/39 (23%) grade 4 and one fatal complication in those with primary cervical carcinoma. The overall fistulae rate was 11% (4/39) with three patients developing rectovaginal fistulae and one having vesicovaginal fistula. CONCLUSION: Concurrent chemotherapy and irradiation for advanced gynecologic malignancies as administered in this study is highly toxic and fails to demonstrate an obvious survival improvement.
