Impact of Pelvic and Para-aortic Lymphadenectomy in Advanced Ovarian Cancer After Neoadjuvant Chemotherapy

The aim of our study was to evaluate the impact of systemic pelvic and para-aortic lymphadenectomy on survival in patients with advanced ovarian cancer after neoadjuvant chemotherapy.This multi-centric descriptive study included patients with initially inoperable advanced ovarian cancer, undergoing neoadjuvant chemotherapy followed by cytoreductive surgery with no residual tumor between 1998 and 2012. They were distributed into two groups depending on if they underwent lymphadenectomy or not during the interval surgery.Among the 101 included patients, 54 underwent lymphadenectomy and 47 did not. The multivariate analysis for overall survival showed no significant difference between the two groups [hazard ratio (HR)=1.88, confidence interval (CI)=0.89-3.94; p=0.08]. The multivariate analysis for progression-free survival showed no significant difference (HR=1.43, 95% CI=0.86-2.39; p=0.17).In patients with advanced ovarian cancer, treated by neoadjuvant chemotherapy and interval surgery with no residual tumor, lymphadenectomy does not seem to improve the survival rate.
