Kidney cancer trial: to cut or not to cut after immunotherapy?

NCT ID NCT03977571

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study looks at whether removing the kidney tumor after starting immunotherapy helps people with advanced kidney cancer live longer. About 400 participants will be randomly assigned to have surgery or not. The goal is to see if delayed surgery improves overall survival compared to no surgery at all.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

Cytoreductive nephrectomy (surgery to remove part or all of the kidney)

What this could lead to

If successful, this could show that delayed kidney removal after immunotherapy helps people with advanced kidney cancer live longer.

What could go wrong

This is a Phase 2/3 trial, so results are not yet proven. Surgery carries risks like infection or bleeding, and the benefit over no surgery is uncertain.
