Robotic RPLND for stage IIA/B nonseminoma: the Princess Margaret Experience.

Purpose: Retroperitoneal lymph node dissection (RPLND) is a treatment option for men in a primary and post-chemotherapy setting. The aim of this review was to explore the published data looking at feasibility, safety and outcomes of robotic RPLND for CSI/II NSGCT but we will in particular highlight how we have approached adoption of robotic RPLND at the Princess Margaret.

Methods: A review and summary of the published data to date was performed regarding the role of robotic RPLND for stage IIA/B nonseminoma.

Results: Published series of robotic RPLND to date have proven feasibility and safety in experienced centres. Less blood loss, shorter length of stay and decreased morbidity are promising findings. Our data from Princess Margaret strengthen the argument of oncologic efficacy as we operated only on patients with known retroperitoneal disease (Stage at RPLND was IIA (n = 15, 55.6%), IIB (n = 9, 33.3%), IIC (n = 1, 3.7%) and III (n = 2, 7.4%)), did not use adjuvant chemotherapy and found a relapse rate (11%) similar to open RPLND.

Conclusions: The debate is ongoing regarding the role of robotic RPLND- the excellent oncological outcomes achieved by an open RPLND are the minimum starting point for robotic RPLND. Until such time that robotic RPLND is proven to be gold standard it should be performed in experienced centres by high volume RPLND surgeons and in the setting of a protocol.
