Summary

This study looks at whether a blood test for a protein called hPG80 can help find neuroendocrine tumors (NETs) earlier in people with MEN1, a genetic condition that raises tumor risk. About 297 participants with MEN1 will give blood samples, which will be compared to standard imaging tests. If hPG80 works well, it could offer a simpler, less stressful way to monitor for these tumors.
