Introduction/Background Our purpose was to analyse the Overall Survival (OS) and Disease-Free Survival (DFS) comparing the different factors that impact on survival.

Methodology A total of 140 patients with ovarian cancer were included, underwent complete cytoreductive surgery in 118 cases and chemotherapy in 22 cases. Mean age was 57 years (18–90). Pathology most common was high grade serous carcinoma (48.6%). FIGO initial stages (I–II, 66 cases) and advanced stages (III–IV, 74 cases). Mean Ca 1.25 prior to surgery was 467 U/dL (3–6,790). Exploratory laparoscopy, predictive index value, peritoneal carcinomatosis index, residual tumor and surgical complexity score was reported. We compared differences by survival prognostic factors using univariate and multivariate analysis.

Results In 92 cases pelvic and para-aortic lymphadenectomy were performed. Lymph node involvement was detected in 14.3% cases. 94 patients underwent Primary Debulking Surgery (PDS) (79%), and 24 cases neoadjuvant chemotherapy (NAC) and interval surgery. The median follow-up was 41.2 months.

The estimated 5-year DFS and OS comparated rates respectively were: In initial FIGO stages were 87.3 and 88.7%, vs advanced stages 53.4 and 51.5% (p=0.00 Hazard ratio 4.65 (CI 95%, 1,86–11.62) and p=0.00 Hazard ratio 6.34 (CI 95%, 2.43–16.58). When lymphadenctomy was performed were 75 and 79.6%, vs no 72 and 57.6% (p=0.97 and p=0.01 Hazard ratio 2.31 (CI 95%, 1.14–4.68). If lymph node involvement was detected were 33.7 and 65.3%, vs no 76 and 79.3% (p=0.00 Hazard ratio 3.32 (CI 95%, 1.3–8.43) and p=0.17). In advanced stages, with PDS 44.7 and 59.2%, vs NAC 0 and 24.9% (p=0.05 and p=0.48); microscopical residual 78.8 and 88.1%, vs gross residual 35.2 and 33.4% (p=0.00 Hazard ratio 3.25/CI 95%, 1.49–7.09) and p=0.00 Hazard ratio 6.89 (CI 95%, 2.98–15.93).

Conclusion OS increased in case of initial stages, complete debulking with microscopic residual and patients who underwent with lymphadenectomy.
