To evaluate whether response to alpha-2- or gamma-interferon in metastatic renal cell carcinoma is associated with a prolonged survival, we studied a total of 65 patients being treated in two phase-II- or phase-III-trials between 1984 and 1986 with one of these interferons. After a median follow-up of 3 years for the alpha-interferon-treated patients and of more than 4 years for gamma-interferon-therapy, respectively, there is a significantly increased duration of survival for patients showing an objective response or stabilisation of the disease due to either therapy compared to those with continuing progression. Therapy with alpha-interferon leading to objective remissions in 26% or with gamma-interferon with an objective response rate of 36% therefore is beneficial for responding patients and can be performed with moderate side effects on an out-patient basis.
