Objective To evaluate the incidence and possible predictors associated with port‐site metastases following robotic surgery. Design Prospective study. Setting University Hospital. Population Women with gynecological cancer. Methods The occurrence of port‐site metastases in the first 475 women undergoing robotic surgery for gynecological cancer was reviewed. Main outcome measures Rate of port‐site metastases. Results A port‐site metastasis was detected in nine of 475 women (1.9%). Eight women had either an unexpected locally advanced disease or lymph‐node metastases at the time of surgery. All nine women received postoperative adjuvant therapy. Women with ≥ stage III endometrial cancer and women with node positive cervical cancer had a significantly higher risk of developing a port‐site metastasis, as did women with high‐risk histology endometrial cancer. Port‐site metastases were four times more likely to occur in a specimen‐retrieval port. One (0.2%) isolated port‐site metastasis was detected. The median time to occurrence of a port‐site metastasis was 6 months (range 2–19 months). Six of the nine women (67%) have died and their median time of survival from recurrence was 4 months (range 2–16 months). Conclusion In women with gynecological cancer, the incidence of port‐site metastases following robotic surgery was 1.9%. High‐risk histology and/or advanced stage of disease at surgery seem to be contributing factors.
