Phase II trial of methotrexate, vinblastine, doxorubicin, and cisplatin in advanced/recurrent endometrial carcinoma

A phase II combination chemotherapy protocol combining methotrexate, vinblastine, doxorubicin, and cisplatin was designed to evaluate tumor response and survival in patients with advanced/recurrent endometrial carcinoma. Thirty patients with advanced/recurrent endometrial carcinoma were assigned to chemotherapy treatment at 4-week intervals with methotrexate 30 mg/m2 i.v. Days 1, 15, and 22; vinblastine 3 mg/m2 i.v. Days 2, 15, and 22; doxorubicin 30 mg/m2 i.v. Day 2; and cisplatin 70 mg/m2 i.v. Day 2. After a median of four cycles (maximum number two cycles beyond complete regression; minimum six cycles for stable partial regression), we observed objective regression in 20 patients (67%) (95% CI, 50, 84) with complete regression in 8 patients (27%) and partial regression in 12 patients (40%). Median overall survival was 9.9 months (range, 0.3-34.2), and median survival of responders was 11.0 months (range, 2.6-34.2) from initial date of response. Toxicity was substantial with two treatment-related deaths and consisted predominantly of neutropenia (grade 3 or greater in 93% of the patients), alopecia, nausea, emesis, stomatitis, and azotemia. In conclusion, MVAC is a highly active outpatient chemotherapy regimen in patients with advanced/recurrent endometrial carcinoma, achieving a high complete and partial response rate. Toxicity is substantial in this elderly patient population.
