ABSTRACT
The following paper reports the evaluation of 53 consecutive patients with advanced ovarian epithelial carcinoma (FIGO stage III-IV), treated between October 1984 and December 1987 with immediate or delayed cytoreduction surgery and chemotherapy. Combination chemotherapy consisted of cisplatinum 45 mg/m2 i.v. for 2 consecutive days and cyclophosphamide 900 mg/m2 i.v. on the second day, administered every 28 days for a maximum of 8 courses. Objective responses were observed in 35 of 50 evaluable patients (70%), 17 (34%) of whom were pathological complete remissions (pCR). For patients with minimal residual disease before chemotherapy a higher pCR rate was achieved (10/20 vs. 7/30; p = N.S.). Median survival time of all patients was 29 months; subjects with minimal residual disease and good performance status before treatment had higher survival (48 vs. 22 months-p < 0.05 and 29 vs. 9 months-p < 0.05, respectively). Median time to progression was 25 months. After a median follow-up of 60 months, 15 (28%) patients were alive, 14 of whom disease-free. Toxicity was moderate with a particularly low incidence of nephrotoxicity and no case of serious long-lasting neuropathy. These findings suggest that the described combination has an efficacy comparable to other CDDP-containing combinations, using 2, 3 or more drugs, with a low incidence of acute serious toxicities and of disabling delayed sequelae.

AIMS AND BACKGROUND: The clinical use of cisplatin (CDDP), one of the most active agents in advanced ovarian cancer, is limited by nephrotoxicity and cumulative neurotoxicity. In preclinical studies, reduced glutathione (GSH) demonstrated a protective action against CDDP nephrotoxicity. We treated 20 patients with advanced ovarian carcinoma, with polychemotherapy containing CDDP + GSH, to assess the protective action of GSH against CDDP nephrotoxicity. METHODS: Between January 1988 and December 1989, 20 patients, with advanced ovarian carcinoma (St. III-IV-FIGO), not pretreated received CDDP: 45 mg/m2 i.v., on day 1-2, + cyclophosphamide (CPA): 900 mg/m2 i.v. on day 2 + GSH 2500 mg i.v. in normal saline 100 ml (in 15 min), before CDDP, every 21-28 days. RESULTS: A pathologic complete response rate (PCR) of 55% (11/20) was observed (7/14 patients with bulky disease). Median survival was 26.5 months and 5 patients were still alive and disease free at 35 months. Toxicity was limited, without any case of nephrotoxicity. CONCLUSIONS: On the basis of our previous experience with the same regimen without GSH, this study suggests that also in the clinical setting, GSH has no negative interference on CDDP activity and that GSH might improve the therapeutic index of CDDP. However, our data need to be confirmed by large randomized clinical studies.

Myometrial biopsies were taken on 45 women less than 40 years old either by laparoscopy or laparotomy, searching for adenomyosis "in vivo". A positive response of 5 cases (11.11%) may prove adenomyosis to affect significantly young women too and not to be closely connected with the usually reported pathogenetic factors.
