Robotic Postchemotherapy Retroperitoneal Lymph Node Dissection for Testicular Cancer

Area of Science:

• Urology
• Surgical Oncology
• Minimally Invasive Surgery

Background:

• Postchemotherapy retroperitoneal lymph node dissection (pcRPLND) is standard for nonseminomatous germ cell tumors with residual masses.
• The open approach for pcRPLND is associated with significant perioperative morbidity.

Purpose of the Study:

• To assess the feasibility of robotic pcRPLND (r-pcRPLND).
• To establish selection criteria for robotic pcRPLND.
• To compare outcomes of robotic versus open pcRPLND (o-pcRPLND).

Main Methods:

• Retrospective review of 93 patients undergoing pcRPLND (30 robotic, 63 open) by a single surgeon.
• Comparison of clinicopathologic characteristics, intraoperative variables (OR time, EBL), and postoperative outcomes (LOS, complications).
• Assessment of oncologic outcomes including nodal yield, recurrence rates, and cancer-specific survival.

Main Results:

• Robotic pcRPLND was performed in a selected cohort with lower clinical stage and smaller masses.
• Robotic pcRPLND demonstrated significantly lower estimated blood loss and shorter hospital stay.
• Operating room time was similar, and oncologic outcomes, including nodal yield and recurrence rates, were comparable between robotic and open approaches.

Conclusions:

• Robotic pcRPLND is a safe and feasible option for carefully selected patients.
• Robotic surgery can reduce perioperative morbidity associated with pcRPLND.
• Rigorous patient selection is key to successful robotic pcRPLND outcomes.
