Objective: To evaluate the relationship between the pelvic and para-aortic lymphadenectomy and the prognosis of epithelial ovarian cancer. Methods: 287 patients suffering from primary epithelial ovarian cancer from 1995 to 2005 were analyzed retrospectively. Results: The 3-, 5-, 10-year survival with systematic lymphadenectomy (SL) were slightly higher than those without SL, but there were no statistically significance (P ＞ 0.05). The 3-, 5-, 10-year survival of clinical stages without SL were lower than those with SL, but there were no significant difference either (P ＞ 0.05). The 3-,5-, and 10-year survival rates with SL were higher than those without SL with no statistically differences (P ＞ 0.05) among the subgroups such as absent, ≤ 2 cm and ＞ 2 cm residual tumor. The survival rates of the groups without residual tumor and the group with ≤ 2cm residual tumor were significantly higher than that of ＞ 2 cm (P ＜ 0.005). On multivariate analysis, patient staging (P = 0.01)and size of residual disease after primary cytoreductive surgery (P ＜ 0.001 and = 0.002, respectively) retained prognostic significance. SL was not proved to be an independent prognostic factor (P = 0.69). Conclusion: Systematic pelvic and paraaortic lymphadenectomy can not improve and prolong the survival time significantly.
