Phase II studies of bleomycin, cyclophosphamide, doxorubicin and cisplatin, and bleomycin and cisplatin in advanced cervical carcinoma

In a randomized phase II trial of two cisplatin-based chemotherapy regimens, 45 patients with advanced cervical carcinoma received a combination of bleomycin, cyclophosphamide, doxorubicin, and cisplatin (BCAP), and 45 others received bleomycin plus cisplatin (BP). BCAP was repeated every 4 weeks, and BP was given at 3-week intervals. Although 19 of 43 (44%) evaluable patients receiving BCAP and 16 of 42 (38%) evaluable patients receiving BP experienced tumor regression, only 22% of those receiving BCAP and 21% of those on BP survived 1 year after beginning treatment. Among bidimensionally measurable patients, 15 of 27 (56%) and 8 of 25 (32%) receiving BCAP and BP, respectively, achieved tumor regression. One patient died of bleeding resulting from severe myelosuppression on BCAP, and two others succumbed to pulmonary toxicity of bleomycin on the BP regimen. Although active against cervical carcinoma, these regimens have limited therapeutic value at this advanced stage of the disease.
