title: Chemotherapy for mustard-resistant ovarian adenocarcinoma: a randomized trial for CCNU and methyl-CCNU.
abstract: In view of the need for drugs which have antitumor activity in alkylating agent-resistant ovarian cancer or which might be more potent than standard agents, a randomized trial of two nitrosoureas, CCNU and methyl-CCNU, has been conducted. Of 31 evaluable patients who received at least one dose of CCNU (100 mg/m2 orally every 6 weeks), there were only two patients who experienced even transient improvement; 18 of these patients had two or more doses over a trial period of greater than or equal to 12 weeks. Of 26 evaluable patients who received at least one dose of methyl-CCNU (150 mg/m2 orally every 6 weeks), there was one patient who experienced transient improvement; this group included 14 patients receiving at least two doses and whose trial lasted greater than or equal 12 weeks. All patients had been previously treated with mustard-type alkylating agents. None of the responses were clinically useful. Thus, women with ovarian adenocarcinoma who have a history of prior chemotherapy are not likely to benefit from treatment with these nitrosoureas.
