Radiation's hidden immune impact: key to better cervical cancer treatment?
NCT ID NCT06804135
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at how pelvic radiation therapy changes the immune system in people with cervical cancer. Researchers want to understand if radiation helps or hurts the body's ability to fight cancer long-term. About 110 participants will provide blood and tumor samples before, during, and after treatment. The goal is to use this information to improve radiation plans and lower the chance of cancer coming back.
