Although radical nephrectomy (RN) is the most common treatment for kidney can-cer, no data on the learning curve for RN are available.

Abstract
Although radical nephrectomy (RN) is the most common treatment for kidney can-cer, no data on the learning curve for RN are available. In this study we investigated the effect of surgical experience (EXP) on RN outcomes using data for 1184 patients treated with RN for a cT1-3a cN0 cM0 renal mass. EXP was defined as the total num-ber of RNs performed by each surgeon before the patient's operation. The primary study outcomes were all-cause mortality, clinical progression, Clavien-Dindo grade >2 postoperative complications (CD >2), and the estimated glomerular filtration rate (eGFR). Secondary outcomes were operative time, estimated blood loss, and length of stay. Multivariable analyses adjusted for case mix revealed no evidence of association between EXP and all-cause mortality (p = 0.7), clinical progression (p = 0.2), CD >2 (p = 0.6), or 12-mo eGFR (p = 0.9). Conversely, EXP was associated with shorter operative time (estimate -0.9; p < 0.01). Mortality, cancer control, mor-bidity, and renal function might not be affected by EXP. The very large cohort exam-ined and the extensive follow-up support the validity of these negative findings. Patient summary: For patients with kidney cancer undergoing surgical removal of a kidney, those treated by novice surgeons have similar clinical outcomes to those treated by experienced surgeons. Thus, this procedure represents a convenient sce-nario for surgical training if longer operating theatre time can be planned. (c) 2023 The Authors.
