First seen Apr 10, 2026 · Last updated Jun 10, 2026 · Updated 8 times

Summary

This study is for adults with hyperparathyroidism, a condition where the parathyroid glands produce too much hormone, causing high calcium levels. Researchers will analyze tumor samples from 839 people who need surgery to see if the tumors are made of one cell type (monoclonal) or many (polyclonal). The goal is to better understand these tumors and how they affect treatment outcomes.
