ABSTRACT
BACKGROUND:
To validate a novel trifecta for evaluating outcomes of partial nephrectomy (PN) on a multicentric dataset.METHODS:
Between 2007 and 2020, three renal cancer databases were queried for patients with solitary renal masses who underwent PN (n = 649). Trifecta was estimated for overall cohort and contributing centers. Overall survival (OS), cancer-specific survival (CSS) and end-stage renal disease (ESRD) probabilities were assessed by Kaplan-Meier. Cox regression was used to identify predictors of OS, CSS, ESRD. For all analyses, a p < 0.05 was considered significant.RESULTS:
At a median follow-up of 22.7 months (IQR 12.5-76.5) overall trifecta was 76.7% [Centre A; (n = 230; 68.6%), B (n = 68; 77.3%), C (n = 200; 88.4%); p = 0.001). On Kaplan-Meier, patients achieving trifecta exhibited higher OS (p = 0.024), higher CSS (p = 0.015) and lower ESRD rates (p = 0.024). On multivariable analysis, age (HR 1.04; 95% CI 1.01-1.08) and trifecta (HR 0.34; 95% CI 0.15-0.76) were independent predictors of OS while pT stage (HR 1.95; 95% CI 0.45-8.43) and trifecta (HR 0.33; 95% CI 0.16-0.67) were predictors of CSS (each p < 0.01). Preoperative CKD stage ≥ 3a (HR 13.1; 95% CI 4.07-42.6) and trifecta (HR 0.41; 95% CI 0.19-0.87) were independent predictors of ESRD (each p < 0.05).CONCLUSIONS:
On external validation, trifecta was an independent predictor of all PN endpoints, regardless of hilar control and ischemia duration.
