Abstract
OBJECTIVES: To evaluate the perioperative and oncological/functional outcomes of robotic post-chemotherapy retroperitoneal lymph node dissection for testicular cancer.
METHODS AND MATERIALS: In this retrospective study, we included patients who underwent robotic post-chemotherapy retroperitoneal lymph node dissection at 7 academic centers between 2011 and 2021. Patients' characteristics, perioperative findings, as well as oncological and functional outcomes are reviewed. Relationships with the main outcome (90-day complications) were analyzed using multivariable logistic regression.
RESULTS: A total of 90 patients with a median (IQR) age of 30 (25-37) years were included. The main primary histologic type was non-seminomatous germ cell tumor (89%). Seven patients (8%) were electively converted to open. Median estimated blood loss, operative time, and length of hospital stay were 150 ml, 5.6 hours, and 2 days, respectively. Final pathology revealed teratoma in 49 (55%), necrosis/fibrosis in 29 (32%), and viable germ cell tumor in 12 (13%) patients. The 90-day complication rate was 16.7%, most of which were low-grade (Clavien-Dindo < III) and managed conservatively. On multivariable analysis, pure seminoma (odds ratio 17.4) and bilateral dissection template (odds ratio 4.2) were independently associated with 90-day complications. No 90-day hospital readmission was recorded. With a median (IQR) follow-up of 16 (4-32) months, 6 (6.7%) patients had disease recurrence and there was 1 cancer-related death.
CONCLUSION: With appropriate patient selection at centers with expertise in testicular cancer and minimally invasive surgery, robotic post-chemotherapy retroperitoneal lymph node dissection appears safe and effective, although longer follow-up is warranted.
