Vinorelbine and interferon-alpha2c as second-line therapy in metastatic renal cell carcinoma

Abstract

Second-line treatment of patients with metastatic renal cell carcinoma (MRCC) progressing under therapy with biological response modifiers (BRM) is an unresolved issue. Thirty-seven patients with MRCC progressing under treatment with BRM received vinorelbine i.v. at a dose of 30 mg/m2 q 22 days and 4,800,000 IU interferon (IFN)-alpha2c s.c. thrice weekly. Partial remission (PR) occurred in 8% of patients, stable disease (SD) (median duration 8, range 3-35+ months) was observed in 46% of patients. Median overall survival was 15 (range 1-49) months. No major toxicities occurred. Patients with MRCC who failed first-line treatment with BRM had a high chance to enter PR or SD under combined, low-toxic therapy with vinorelbine and IFN-alpha2c.
