Molecular and Immunohistochemical Profiling of Parathyroid Tumors to Improve Diagnosis and Treatment

What this Trial Is About

Researchers are studying molecular and immunohistochemical profiling of tumors in patients with parathyroid tumors, including parathyroid carcinoma, atypical neoplasm, and parathyroid adenoma. The purpose is to better understand differences in clinical behavior and identify genes that may help improve diagnosis. This research aims to reduce inconsistencies in diagnosis, avoid unnecessary or incomplete surgery, and improve follow-up care for patients with parathyroid tumors. The study analyzes previously collected tumor tissue and blood samples from patients with parathyroid tumors. These samples are examined using immunohistochemical profiling to identify potential genes showing molecular changes similar to other cancers. This observational study involves laboratory biomarker analysis and correlative studies without new treatments or interventions. Participants are patients with available tissue or blood samples consented for research, collected from 1968 to 2015 at MD Anderson Cancer Center or collaborating sites. Researchers measure biomarker levels and identify potential diagnostic genes over a period of up to four years. No new visits or treatments are involved, as the study uses existing samples and medical data for analysis and assessment.
