PHASE-II TRIAL OF METHOTREXATE, VINBLASTINE, DOXORUBICIN, AND CISPLATIN IN ADVANCED RECURRENT CARCINOMA OF THE UTERINE CERVIX AND VAGINA

A phase II combination chemotherapy protocol combining methotrexate, v inblastine, doxorubicin, and cisplatin was designed to evaluate tumor response and survival in patients with advanced/recurrent recurrent ce rvix and vaginal cancer. Twenty-nine patients with advanced/recurrent cervix cancer and three patients with advanced vaginal cancer who had not previously received cytotoxic chemotherapy were assigned to chemot herapy treatment at 4-week intervals with methotrexate 30 mg/m2 iv, Da y 1, vinblastine 3 mg/m(2) iv, Days 2, 15, and 22, doxorubicin 30 mg/m 2 iv, Day 2, and cisplatin 70 mg/m(2) iv, Day 2. After a median of 4 c ycles (maximum number 2 cycles beyond complete regression; 6 cycles wi th stable regression); we observed objective regressions in all 3 pati ents with vaginal cancer and 19 patients (66%, 95% CI = 46,82) with ce rvix cancer including complete regression in 6 patients (21%, 95% CI = 8,40) and partial regression in 13 patients (45%, 95% CI = 26,64). Me dian overall survival was 11.5 months (range 1.1-54+). Median survival of responders was 12.8 months (range 3.6-54+). Toxicity included neut ropenia, alopecia, nausea, emesis, and stomatitis, Although grade 3 an d 4 neutropenia was observed in over half of the patients, there were no treatment-related deaths. In conclusion, MVAC is a highly active ou tpatient chemotherapy regimen in patients with advanced/recurrent cerv ix cancer, achieving a high complete and partial response rate with mo derate hematologic toxicity, These results need to be confirmed by pha se III trial in advanced disease patients and MVAC may be a suitable r egimen for investigation in neoadjuvant chemotherapy trials in poor pr ognosis, previously untreated patients.
