Clinical Question

In patients with metastatic renal cell carcinoma, does cytoreductive nephrectomy followed by interferon therapy result in longer progression free and overall survival than interferon alone?

Bottom Line

Radical nephrectomy before interferon-based immunotherapy substantially delays time to progression and improves survival of patients with metastatic renal cell carcinoma who present with good performance status.

Major Points

This study along with SWOG 8949, were the first to demonstrate survival benefit from cytoreductive nephrectomy in the setting of metastatic RCC.

This study found that cytoreductive nephrectomy plus interferon alfa resulted in improved median overall survival when compared to interferon alfa alone (17 vs. 7 months).
