[Systemic therapy of renal cell carcinoma]

Systemic therapy of metastatic renal cell carcinoma has completely changed in the last 5 years. Although a cure for the disease is still not achieved with systemic treatment in the majority of cases immunotherapy is no longer used. The therapeutic regiments are mainly based on angiogenic inhibitors such as sunitinib, sorafenib, pazopanib, everolimus and temsirolimus as well as the combination of bevacizumab with interferon. This article gives an overview of these treatment options and the clinical setting for their usage. To achieve a prolonged progression-free survival, a continuous therapy based on the new drugs is necessary. The major goal of the treatment remains to keep the disease stable as complete remission is only seen in 2-4% of cases. With these lengthy treatment regimes a schedule for sequenced administration of drugs is necessary for most of the patients. The optimal treatment sequence is unknown and should be chosen based on the individual course of the disease and the side effects as well as comorbidities. The role of neoadjuvant and adjuvant therapies remains unclear.
