Background: Nephrectomy and risk-adapted adjuvant pembrolizumab are standard treatments in localized renal cell carcinoma (RCC). Risk of recurrence from clinical trials is utilized to council patients. However, recurrence and survival in real-world practice may differ. We report real-world outcome data of patients with RCC from the German Cancer Consortium’s Clinical Communication Platform, a federated data warehouse infrastructure for oncological real-world evidence. Methods: Adult patients from routine care and nephron sparing surgery (NSS) or nephrectomy (Nx) for non-metastatic RCC between 2013-2022 at tertiary German cancer centers were retrospectively analyzed. Clear cell (cc), papillary (p) or NOS histologies were eligible. Kaplan-Meier-analyses were conducted stratified by pathological stage for DFS (Disease-Free-Survival) and OS (overall Survival). Results: 1,291 patients received NSS/Nx. 1,271 (98.5%) were R0/1. Median follow-up: 37.8 mo. (IQR 13.08; 65,74). 754 patients had ccRCC with a mean age of 63.5 y (SD: 12.1), 40% were female. 221 had pRCC, mean age was 62.1 (SD 12.6) and 36.8% were female. 165 had NOS, mean age was 63.3 (SD 12.4) and 36.8% were female. 151 patients had other histologies. Survival outcomes are reported in table 1. Conclusions: Morphologic RCC types and T-stages inform on recurrence and prognosis. Our study advises on real-world recurrence and survival rates in patients with different RCC types, which may be used to counsel patients with regards to adjuvant therapy in the clinic. A major limitation is the retrospective nature of the analysis.
