Low-dose IL-2 Plus IFN-alpha Immunotherapy as Adjuvant Treatment of Renal Carcinoma.

Summary

The aim of this study is to compare the efficacy (in terms of event-free survival and overall survival) of an adjuvant therapy with IFN-alpha plus low-dose of IL2 vs a wait-and-see program in patient with radically operated renal cell carcinoma.
