We conducted a joint phase II study in 76 patients with gynecological cancer (42 patients with ovarian cancer, 22 patients with cervical cancer, 10 patients with endometrial cancer and 2 patients with vaginal cancer). The response rate was 25.0% in the patients with ovarian cancer, 13.3% in those with cervical cancer, and 28.6% in those with endometrial cancer. The overall response rate was 23.1%. When the patients were classified according to dose schedules, the highest response rate was obtained in the group administered THP-ADM at a dose of 60 mg per body by single i.v. injection at 3-week intervals. Such side effects as myelosuppression and gastrointestinal disturbances were observed, but alopecia, a marked side-effect of ADM administration, was mild, and no cardiac toxicity was seen in any of the patients.
