Perioperative and oncologic outcomes of open radical nephrectomy and inferior vena cava thrombectomy with liver mobilization and Pringle maneuver for Mayo III level tumor thrombus: single institution experience.

BACKGROUND Scarce data are available regarding the technique and outcomes for patients with RCC and Mayo III caval thrombi. To report surgical and oncological outcomes of RCC patients with Mayo III thrombi treated with radical nephrectomy and thrombectomy after liver mobilization (LM) and Pringle Manoeuvre (PM). METHODS Retrospective analysis of surgical technique, outcomes and cancer control in 19 patients undergoing LM and PM in a single tertiary care institution. RESULTS Overall, 78% of the patients had performance status ECOG 1 and 58% had a comorbidity index >2. Median surgical time was 305 minutes (IQR 264-440). Intraoperative complications were reported for 39% of patients and postoperative ones for 58% (only Grade 1 and 2). Intensive Care Unit support was necessary in 16% of the cases. Median length of hospital stay was 9 days (IQR 7-11). Thirty- and 90-day mortality were 5% and 15%. Twoyear overall survival and cancer-specific survival were 60% and 62%, respectively. CONCLUSIONS We reported surgical techniques, intra and perioperative complications and follow-up in the largest cohort of RCC patients requiring LM and PM.
