Outcomes and Predictors of Clinical T1 to Pathological T3a Tumor Up-Staging after Robotic Partial Nephrectomy: A Multi-Institutional Analysis

At short-term followup patients with renal cell carcinoma up-staged from cT1 to pT3a have reasonable oncological outcomes after partial nephrectomy. Factors associated with tumor up-staging include high tumor complexity, increasing tumor diameter and hilar location. Further studies are needed to determine the comparative efficacy of partial vs radical nephrectomy for small pT3a tumors.
