Summary

This study tests whether removing the kidney after successful immunotherapy can help patients with metastatic kidney cancer stop all treatment and stay cancer-free. About 60 adults whose tumors have shrunk significantly with immunotherapy will either have surgery and stop therapy, or continue therapy without surgery. The goal is to see if this approach can lead to long-term remission and potentially a cure.
