Blood tests may predict cancer return after radiation

NCT ID NCT03325036

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study measured immune-related substances in the blood of 60 head and neck cancer patients before and after they received curative radiotherapy. The goal was to see if these markers could help predict whether the cancer would come back or spread. Researchers hope to find better ways to identify patients who need closer monitoring after treatment.

What this could lead to
If successful, this could help doctors use blood tests to predict which patients are at higher risk of cancer returning after radiotherapy.
What could go wrong
This is a small, completed observational study, not a treatment trial. The findings may not lead to a widely used test or change patient care directly.
