Survival of metastatic renal cell carcinoma patients continues to improve over time, even in targeted therapy era.

The introduction of new therapeutic agents resulted in CSM-free survival improvement over study time. However, this effect exclusively applies to patients with ccmRCC, but not to those with non-ccmRCC. This observation is in agreement with established efficacy of systemic therapies for ccmRCC, but lesser efficacy of these agents for non-ccmRCC.
