In 1980, second-look laparotomy was introduced simultaneously into the treatment regimen for ovarian carcinoma at the two main referral centers of northern Spain. First-line chemotherapy after initial surgery was, however, different at both hospitals. At one of them (Bilbao), a combination involving the use of cisplatin was employed (cyclophosphamide 600 mg/m2, Adriamycin 45 mg/m2, and cisplatin 80 mg/m2 i.v. on day 1), whereas the patients of the other hospital were treated mainly with single-agent chemotherapy (melphalan 0.2 mg/kg p.o. on days 1–5) and never with a cisplatin combination as first-line therapy in any case. In all, 92 patients (42 stage I, 14 stage II, 33 stage III, and 3 stage IV) could be treated during the study period with optimal surgery (complete tumor excision or largest residual tumor less than 2 cm in diameter). This was followed by adjuvant chemotherapy for 12–18 months in all cases, except for 18 patients with a stage la borderline or G1tumor. The latter were merely kept under observation until their second-look laparotomy after 1 year of negative follow-up. All of the 74 patients who received adjuvant chemotherapy, of whom 36 with cisplatin and 38 without, were clinically disease free after at least twelve courses of treatment and had a second-look laparotomy performed. This was positive in 33.3% of the cases after cisplatin-containing therapy and in 26.3% of the cases after cisplatin-free therapy. This difference is not statistically significant. The mean follow-up period after negative second-look was 34 months. The long-term results of both patient groups were comparable as far as rate of positive second-look laparotomies and survival rate, overall and stage for stage are concerned. The use of cisplatin did not result in any significant therapeutic improvement. It was uniformly bad tolerated by the patients and carried higher cost, since all patients had to be hospitalized for treatment.
