Recent robust data allow for omitting lymph node dissection for patients with advanced epithelial ovarian cancer (EOC) and without any suspicion of lymph node metastases, without compromising recurrence-free survival (RFS), nor overall survival (OS), in the setting of primary surgical treatment. Evidence supporting the same postulate for patients undergoing complete cytoreductive surgery after neoadjuvant chemotherapy (NACT) is lacking. Throughout a systematic literature review, the aim of our study was to evaluate the impact of lymph node dissection in patients undergoing surgery for advanced-stage EOC after NACT. A total of 1094 patients, included in six retrospective series, underwent either systematic, selective or no lymph node dissection. Only one study reveals a positive effect of lymphadenectomy on OS, and two on RFS. The four remaining series fail to demonstrate any beneficial effect on survival, neither for RFS nor OS. All of them highlight the higher peri- and post-operative complication rate associated with systematic lymph node dissection. Despite heterogeneity in the design of the studies included, there seems to be a trend showing no improvement on OS for systematic lymph node dissection in node negative patients. A well-conducted prospective trial is mandatory to evaluate this matter.
