The value of a cross-discipline team-based approach for resection of renal cell carcinoma with IVC tumor thrombus: A report of a large, contemporary, single-institution experience.

INTRODUCTION

We report the evolution of the largest, contemporary, single-institution experience with this complex procedure to highlight the value of a cross-discipline, team-based approach.

METHODS

Patients from a prospectively maintained database who underwent resection of renal cell carcinoma (RCC) with inferior vena cava (IVC) tumor thrombus from 2005 to 2016 at a single-institution were included for analysis.

RESULTS

Of 140 patients, 102 (73%) had tumor thrombus below the level of the hepatic vein confluence, and 96 (69%) were performed for curative-intent, while 43 (31%) were cytoreductive procedures for clinical trial consideration. Median overall survival (OS) of the entire cohort was 43.8 months (5-year OS:43%), and 73.6 months (5-year OS:59%) for those without metastatic disease. Fifty-one patients underwent resection from 2005 to 2010 and 89 from 2011 to 2016. All procedures since 2011 were performed by the same cross-discipline dedicated team of two surgeons, composed of a surgical and urological oncologist. When comparing the two time-periods, the team-approach after 2011 had shorter operative-times (5.3 vs 6.7 hours; P = 0.009), decreased ICU-utilization (25% vs 72%; P < 0.001), and decreased ICU length-of-stay (0.4 vs 2.2 days; P = 0.001). This group also trended towards less blood loss (1.2 vs 1.8 L), shorter average hospital length-of-stay (10 vs 11 days), and decreased 90-day mortality (6% vs 10%).

CONCLUSION

Resection of RCC with IVC tumor thrombus yields long-term survival. A dedicated, cross-discipline, and team-based approach optimizes patient outcomes and may improve value of care by reducing utilization of expensive hospital resources.
