Immune cell rescue after radiation shows promise in early cancer trial
NCT ID NCT04668833
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether giving patients their own immune cells (called lymphocytes) after chemotherapy and radiation could help their immune system recover faster. It included 19 adults with lung or esophageal cancer. The treatment was designed to reduce a common side effect of radiation—low white blood cell counts—and improve immune health. The study was stopped early, so results are limited, but the approach may be explored further in the future.
