[Advanced renal cell carcinoma - an overview of current systemic therapy]

Renal cell carcinoma (RCC) is one of the more common tumor diseases in older adults. The only curative treatment method is surgical resection in the localized stage. Based on current study data, drug (combination) therapy in the metastatic stage is the most effective treatment option for non-resectable/metastatic RCC (mRCC). Immuno-oncological combinations of 2 Checkpoint-Inhibitors (CPI) or CPIs and Tyrosine kinase inhibitors (TKI) are now standard in the first-line treatment of metastatic RCC. Since the results of foundational combination therapy studies are not fully comparable due to different study design and patient populations, additional clinical and patient-related criteria are required when making individual treatment decisions. The systemic therapy of advanced RCC is therefore based on tumor extent, treatment pressure, concomitant diseases, and personal circumstances. A decision on first-line therapy should be made individually as part of a "shared decision" with the patient. The selection of a second-line systemic therapy is based on individual criteria; the data available for a well-founded classification of a possible therapy sequence after progression to first-line therapy is sparse. Further investigations to optimize systemic therapy (expansion of combination therapy to triple combination of CPI+CPI+TKI) or evaluation of therapy in other histological subtypes of renal cell carcinoma are the subject of ongoing clinical studies.
