Long lasting response to second-line everolimus in kidney cancer.

In the case presented here, everolimus was administered after first line therapy with sunitinib in a patient with metastatic renal cell carcinoma. The safety profile was excellent. The prolonged progression-free survival (PFS) obtained with everolimus in this case is of peculiar interest, as it is a multiple of the median PFS obtained in with everolimus in the regulatory trial. Such finding suggests that a subset of patients with renal cell carcinma may particularly benefit from everolimus.
