The aim of the present study was to investigate response rates, time to progression, and survival with teniposide or carboplatin in patients with advanced or recurrent cervical cancer and to estimate the toxicity of each drug regimen.
Twenty-eight patients with recurrent or advanced cervical cancer entered the study. Two patients were ineligible (severe renal impairment, n = 1; performance status 3, n = 1) and were excluded from the analysis. The remaining 26 patients were randomized to either carboplatin (400 mg/m² on day 1, intravenously every four weeks) or teniposide (125 mg/m² on days 1, 2 and 3, intravenously every four weeks). Twelve patients were randomized to the carboplatin arm and 14 patients to the teniposide arm. They were all comparable with respect to age, performance status, histology, primary FIGO stage, and prior therapy.
Response was seen in four patients in each group (33% and 29%, respectively), all but one being partial. (One patient in the teniposide group had complete response). Time to progression and median survival were similar in the two groups (median time to progression 20/17 weeks and median survival 40/41 weeks, respectively.)
In general, toxicity was moderate. Leukopenia (WHO grade 3 or 4) was seen in one patient treated with teniposide, and thrombocytopenia (WHO grade 3 or 4) in one patient treated with carboplatin. Eleven patients (79%) in the teniposide group had alopecia requiring a wig. The study implies that both drugs have some activity in cervical cancer. Carboplatin has the advantage that it can be administered on an out-patient basis.
