Successful Team-Based Management of Renal Cell Carcinoma With Caval Extension of Tumor Thrombus Above the Diaphragm

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. The aim of this study was 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 maneuver (PM).

METHODS

Retrospective analysis of surgical technique, outcomes and cancer control in 19 patients undergoing LM and PM in a single tertiary care institution were analyzed.

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 complications 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%. Two-year 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.
