A total of 38 cycles of intraperitoneal chemotherapy through implantable injection port were carried out in 9 patients with advanced or recurrent ovarian (tubal) carcinoma. The combination chemotherapy consisted of cisplatin 100 mg or carboplatin 450 mg, 5-FU 500 mg and OK-432 10 KE was administered every four weeks for a total of six cycles. Clinical response was evaluated after chemotherapy. Of the eight evaluated patients (in one patient chemotherapy is not completed yet), 1 had complete response, 3 partial response, 2 stable disease and 2 progressive disease. Therapy-related toxic effects were moderate, consisting chiefly of myelosuppression that seemed dose limiting.
