Long-term survival rates with various chemotherapeutic regimens in stages III and IV ovarian adenocarcinoma. The influence of optimum pretreatment surgical resection.
This report compares long-term survival rates for patients treated with four different chemotherapeutic regimens for Stages III and IV ovarian adenocarcinoma. The patients were entered into consecutive, prospective, randomized studies with an essentially common chemotherapeutic arm. The first study compared the single agent melphalan with actinomycin D, 5-fluorouracil, and Cytoxan. The second study compared 5-fluorouracil plus Cytoxan and methotrexate-leucovorin rescue plus Cytoxan. The patient characteristics in the two studies were very similar except for more aggressive tumor-reductive operations in the second study. Observed survival rates for the first 2 years in the second study were very much higher than in the first study. However, by the third, fourth, and fifth years, the survival rates of the 5-fluorouracil-Cytoxan-treated individuals had reached the same low levels seen in the first study. It appears that an optimum surgical procedure by itself may enhance survival during the first 2 years. Survival with methotrexate-leucovorin rescue plus Cytoxan was statistically significantly better than with melphalan or actinomycin D-5-fluorouracil-Cytoxan. Third-, fourth-, and fifth-year survival rates with methotrexate-leucovorin rescue plus Cytoxan were substantially higher than with 5-fluorouracil-Cytoxan; however, the survival distributions for these two treatments were not statistically significantly different. Long-term survival rate data for patients with Stages III and IV ovarian adenocarcinomas treated with chemotherapy are rare. The 19% 5-year survival rate with methotrexate-leucovorin rescue plus Cytoxan in the present study is considerably higher than other reported survival rates.
