NCT ID NCT04104529
First seen Jun 27, 2026 · Last updated Sep 16, 2026 · Updated 2 times
Summary
This study is creating a large database of medical information and blood samples from 350 adults receiving metabolic radiotherapy for thyroid, prostate, or neuroendocrine cancers. The goal is to provide researchers with valuable data to better understand these treatments. No new therapies are being tested; instead, the focus is on collecting information for future studies.
