Objective. To compare monthly fluorouracil (FU) plus cisplatin and weekly cisplatin concurrent with radiotherapy for locally advanced cervical cancer. Methods. A total of 158 patients (stages IIB through IVA) without para-aortic lymph nodes were randomized to receive 3 monthly cycles of FU (1000 mg/m(2)/day i.v.) plus cisplatin (20 mg/m(2)/day i.v.) for 5 days (group I, n=79) or 6 cycles of weekly cisplatin (30 mg/m(2) i.v.) (group II, n=79), concurrent with definitive radiotherapy. Radiotherapy consisted of external irradiation to the whole pelvis of 41.4-50.4 Gy in 23-28 fractions plus high-dose rate (HDR) intracavitary brachytherapy (30-35 Gy in 6-7 fractions) to point A, together with a parametrial boost. Compliance with treatment, toxicity, response, and survival was analyzed and compared. Results. Of the 158 women, 155 women were eligible for analysis; the median follow-up of surviving patients was 39 months. Full planned chemoradiotherapy was delivered to 47 (60%) and 55 (71%) patients in groups I and II, respectively. The incidence of acute grade 3/4 hematologic toxicity was 43% and 26% (p = 0.037). The complete response rate of each group was 91%. Four-year overall and progression-free survival rates were 70% and 67%, respectively, in group I and 67% and 66%, respectively, in group II. Conclusions. The regimen of chemoradiation using weekly cisplatin significantly improves compliance with treatment and reduces acute hematologic toxicity, while not affecting response and survival rates.
