NCT ID NCT03017794

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

Summary

This study looks at whether a protein in the blood called chromogranin A (CgA) can help predict if prostate cancer will come back after radiation therapy. Researchers will measure CgA levels in 118 men before, during, and after treatment. The goal is to see if changes in CgA are linked to cancer recurrence, which could lead to better monitoring in the future.
