Abstract

Background: It is suggested that immunotherapy may have a better role than cytotoxic chemotherapy in the treatment of metastatic renal cell carcinoma. Aims: A phase II study of α-interferon 2a (IFN2a) and 13-cis-retinoic acid (CRA) in the treatment of metastatic renal cell carcinoma. Methods: Twenty-two patients with no previous systemic therapy were treated with IFN2a daily at 3 million units (MU) and escalated to 6 and 9 MU if tolerated, together with CRA given orally at 1 mg/kg per day in two divided doses. Changes in quality of life were also assessed. Results: Twenty patients were available for assessment. Three patients (14%) achieved a partial response and five patients (23%) had stable disease. No patient achieved a complete response. A durable response was observed in partial responders with median length of response of 44 weeks (range 32-59 weeks). Therapy was stopped in seven (35%) patients due to treatment-related toxicities, and quality of life was worsened in the majority of patients. Conclusion: IFN2a and CRA has a low response rate and significant toxicity, and the combination as standard treatment of metastatic renal cell carcinoma is not recommended, despite the suggestion that CRA may lengthen the response to IFN2a.
