Therapy of mRCC beyond mTOR-inhibition in clinical practice: results of a retrospective analysis

Purpose Renal cell carcinoma (RCC) is the most common renal tumor and accounts for nearly 3 % of adult cancers. In the recent years, seven new targeted agents have been approved changing the treatment in metastatic RCC dramatically. So far, however, it remains unclear which sequence is best for those patients. This study analyzed retrospectively the outcome of patients treated with everolimus after failure of a vascular endothelial growth factor receptor-directed therapy and which therapies were used after everolimus.
