Combination of consecutive low-dose cisplatin with bleomycin, vincristine, and mitomycin for recurrent cervical carcinoma.

Abstract

To evaluate the efficacy and toxicity of combination chemotherapy with bleomycin, vincristine, mitomycin, and consecutive low-dose (CLD) administration of cisplatin (CLD-BOMP) for patients with recurrent cervical carcinoma. Ninety patients with recurrent cervical carcinoma and no prior chemotherapy were enrolled onto this study. The median age was 56 years. Eighty-seven of the 90 patients had received prior radiotherapy. The CLD-BOMP regimen was bleomycin 5 mg infused continuously days 1 through 7; vincristine 0.7 mg/m2 bolus day 7; mitomycin 7 mg/m2 bolus day 7; and cisplatin 10 mg/m2 infused over 4 hours days 1 through 7. The treatment was repeated at 3-week intervals. All 90 patients were assessable for response, toxicity, and survival. After a median of four cycles (range, two to 10 cycles), we observed objective responses in 68 patients (76%), with 25 (28%) complete responses (CRs) and 43 (48%) partial responses (PRs; 95% confidence interval (CI), 66 to 85; 18 to 38; 37 to 59, respectively). Median survival for all 90 patients was 24.3 months (range, 2.3 to 100 months). The median survival for patients who achieved CR, PR, no change (NC), and progressive disease (PD) were not reached (NR), 23.6, 8.2, and 6.4 months, respectively. The median progression-free survival for patients who achieved CR and PR were NR and 12.3 months, respectively. There was no significant nausea or vomiting, nephrotoxicity, or pulmonary toxicity, which was attributable to the CLD-cisplatin and the adequate dosing schedule of bleomycin. The reduced toxicities allowed this regimen to be administered at the projected dose-intensities. The CLD-BOMP regimen has significant antitumor activity with markedly reduced toxicity.
