Complete Salvage Surgical Cytoreduction Improves Further Survival of Patients with Late Recurrent Ovarian Cancer

Abstract

Objective. The aim of this study was to assess the clinical benefit of salvage surgical cytoreduction in patients with late recurrent ovarian cancer.Methods. Thirty patients with recurrent ovarian cancer who underwent salvage surgical cytoreduction were retrospectively reviewed. All had been initially treated by primary surgery and platinum-based chemotherapy and had a period of clinical remission of at least 6 months. Median time to recurrence was 17.5 months (range, 6–76 months).Results. A macroscopically complete salvage cytoreduction was obtained in 17 (56.7%) patients, whereas 8 patients were left with macroscopic residual disease <2 cm and 5 patients with a larger residuum. Logistic regression showed that the probability of achieving a complete cytoreduction was significantly related to the residual disease after initial surgery (<2 cm versus >2 cm, P = 0.0027, odds ratio = 36.000, 95% confidence interval = 3.473–373.176), but not to FIGO stage, tumor grade, histologic type, patient age at recurrence, and time to recurrence. In the whole series median survival following salvage surgery was 21 months. Survival was significantly longer in patients who were completely cytoreduced compared to those who were not (median: 37 months versus 19 months, P = 0.04). Moreover, survival was significantly related to time to recurrence (>17.5 months versus <17.5 months, median: 25 months versus 15 months, P = 0.039), number of recurrence sites (single versus multiple, median: 40 months versus 19 months, P = 0.009), and residual disease after initial surgery (<2 cm versus >2 cm, median: 37 months versus 19 months, P = 0.01), but not to patient age, recurrence site with the largest size, FIGO stage, tumor grade, and histologic type.Conclusions. The present data seem to show that complete salvage surgical cytoreduction significantly improves further survival of ovarian cancer patients who recur at least 6 months after the completion of primary therapy.
