[Adjuvant therapy for renal cell carcinoma : Relevant patient and tumor factors].

The gold standard in the treatment of localized and locally advanced renal cell carcinoma is surgery. Nevertheless, there is still a risk of tumor relapse. Reducing the risk of recurrence and extending overall survival is the goal of subsequent adjuvant treatment. The aim of this work is to discuss the current and future landscape of adjuvant therapy, taking into account the risk-benefit balance in the individual patient selected for adjuvant treatment. The immune checkpoint inhibitor (CPI) pembrolizumab demonstrated a significant increase in disease-free and overall survival after surgery for the first time. However, other CPI studies demonstrated no improvement. Patient selection for adjuvant treatment is currently based on the parameters of the TNM system. Prospective biomarkers are currently not available. Here, kidney injury molecule‑1 (KIM-1) represents an initial promising biomarker in the prediction of adjuvant immunotherapy.
