[Successful treatment of clear cell adenocarcinoma of the ovary (OCCA) with a combination of CPT-11 and mitomycin C].

| Abstract |
Among advanced ovarian cancer, OCCA has worse prognosis compared with serous cystadenocarcinoma because of its poor sensitivity to CDDP-based chemotherapy (CTX). Indeed, there has ever been no one patient with pure OCCA showing an appreciable response to CTX. OCCA has recently been increasing in prevalence and has occupied approximately 20-25% of all ovarian cancer. Thus, there is an urgent need to find effective regimens. Based on the results of chemosensitivity tests previously performed both in vitro and in vivo, we designed a combination of CPT (140 mg/m2, i.v.-infused over 4 hours on day 1, 15, and 29) and MMC (7 mg/m2, i.p. injection through a reservoir on day 1, 15, and 29). The course was repeated every 4 weeks. To date 10 pts were entered The median age was 53 (41-69). Among total 25 courses, grade 3 diarrhea was observed in 3 courses. Other toxic signs were acceptable. The responses by tumor size were 2 CR for disease < or = 2 cm in diameter, and 2 CR, 2 PR, 2 NC, and 2 PD for > 2 cm. Six responders showed a significantly longer survival compared with 4 non-responders (p < 0.0396 for Log-rank test). Thus, the present protocol is the first to demonstrate a significant activity for pure OCCA.
