Understanding tumor types in patients with primary hyperparathyroidism

Official title: A Phase 2 Biomarker Study of Parathyroid Tumor Clonal Status in Hyperparathyroid Disorders (Primary, Secondary, and Tertiary)

Run by Washington University School of Medicine · NCT05997810 · Data updated 2026-11-12

This study is trying to see how often different types of tumors occur in people with primary hyperparathyroidism who are having surgery to remove their parathyroid glands.

Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are females aged 18 and older diagnosed with nonfamilial primary hyperparathyroidism.

Probably not a fit

Patients with recurrent or persistent primary hyperparathyroidism after prior surgery or those with secondary or tertiary hyperparathyroidism due to renal failure may not benefit from this study.

What this trial studies

This observational study aims to determine the frequency of monoclonal and polyclonal tumors in patients diagnosed with primary hyperparathyroidism who are undergoing parathyroidectomy. By comparing surgical and pathological outcomes with tumor clonal status, the study seeks to explore the relationship between tumor characteristics and multiple gland neoplasia. Participants will be recruited from four high-volume medical centers, and tumor samples will be analyzed using established genetic assays to ensure accurate clonal status determination.

Why it matters

Potential benefit: If successful, this study could enhance the understanding of parathyroid tumors, potentially leading to improved treatment strategies for patients with primary hyperparathyroidism.

How similar studies have gone: Previous studies have shown a high concordance rate in tumor clonal status assessment, indicating that this approach has been validated in similar contexts.
