Abstract

Purpose of review: Robot-assisted laparoscopic staging (RALS) is increasingly used for staging epithelial ovarian cancer (EOC). Evidence of its safety is limited. The aim of this review is to compare the efficacy and safety of RALS in clinical early-stage EOC to conventional laparoscopy and laparotomy and to assess the level of evidence that is currently available to adopt this surgical technique.

Recent findings: Only retrospective studies comparing staging by minimally invasive surgery (MIS) to laparotomy are available. Both RALS and conventional laparoscopic staging shorten length of hospital stay (LHS, mean -2.9 days) and decrease estimated blood loss (EBL, mean -79 ml less) compared to laparotomy. Complication rates and number of lymph nodes collected are similar in all surgical staging techniques. Survival outcomes after staging by MIS cannot be compared to staging by laparotomy because of the lack of evidence but RALS is probably noninferior to conventional laparoscopic staging.

Summary: RALS probably improves perioperative outcomes in patients with clinical early stage EOC similar to conventional laparoscopic staging. Whether oncologic outcomes of RALS are comparable to open and conventional approaches is uncertain as there is only level C evidence and randomized controlled trials are urgently needed to confirm the current retrospective findings.
