Abstract

Although tyrosine kinase inhibitors (TKI) are the most common first-line therapy for metastatic renal cell carcinoma, high-dose interleukin-2 (HD-IL2) remains the only agent that provides durable complete responses. The optimal sequence of these agents remains uncertain. This retrospective multi-institutional study examined the safety and efficacy of HD-IL2 following TKI therapy. After IRB approval at 7 HD-IL2 centers, data relating to patient, disease, and treatment characteristics among 40 consecutive patients with metastatic renal cell carcinoma who were treated with HD-IL2 after at least 1 prior TKI therapy were retrospectively collected. The most common cardiac adverse events were grade 3 hypotension and vascular leak syndrome. Six patients (15%) experienced other grade ≥3 cardiac adverse events. There were 2 treatment-related deaths due to congestive heart failure, occurring in 1 patient with short TKI to HD-IL2 interval and another patient with an abnormal baseline cardiac stress test. Best responses included 2 CRs (5%, duration 40+ and 62+ mo), 3 PRs (8%, duration 6, 11, and 24 mo), 13 SD (32%, median duration 12 mo), 20 PD (50%), and 2 not evaluable patients. Median overall survival was 22 months. Administration of HD-IL2 could be safe and effective after TKI therapy; however, careful selection of patients is critical. We recommend baseline cardiac risk factor assessment, screening with both cardiac stress test and echocardiogram, and allowing a TKI to HD-IL2 interval of at least 2 months.
