Popis: Objective. Recurrent ovarian carcinoma is considered an incurable disease and second-line chemotherapy is administered for extension of survival and palliation. The impact of continued antineoplastic treatment in patients with stable disease without a demonstrable response is uncertain. The aim of this analysis was to assess the value of a stabilization of the tumor size in second-line chemotherapy as an indicator of survival. Methods. Retrospective, single-institution study of 487 consecutive patients with primary epithelial ovarian carcinoma. Inclusion criteria: (1) FIGO stage IC–IV epithelial ovarian carcinoma; (2) first-line chemotherapy with Paclitaxel and a Platinum-compound; (3) refractory, persistent, or recurrent disease diagnosed by imaging methods; and (4) intravenous second-line chemotherapy with single Topotecan or Paclitaxel–Carboplatin. Univariate and multivariate analyses of survival with the World Health Organization (WHO) tumor response parameter included as a time-dependent variable were performed. Results. The response rates were ( N = 100): complete response (CR) 27%, partial response (PR) 14%, stable disease (SD) 41% and progressive disease (PD) 18%. In a multivariate Cox regression analysis of survival, SD was found to be an independent prognostic factor for survival and the death hazard ratio was 0.37 (SD versus PD; 95% CI: 0.16–0.86; P = 0.02). There was no statistically significant difference in survival between patients with PR and SD ( P = 0.09). Conclusion. In second-line chemotherapy of ovarian cancer, patients demonstrating SD have a survival benefit compared to patients with PD measured by the WHO tumor response criteria.
