This trial studies molecular and immunohistochemical profiling of tumors in patients with parathyroid tumors. Studying molecular and immunohistochemical profiling of tumors may help doctors avoid inconsistencies in diagnosis, unnecessary or incomplete surgery, surgical morbidity, psychological stress, and inadequate follow up.
PRIMARY OBJECTIVES: I. To determine the differences in clinical behavior and immunohistochemical (IHC) biomarkers between parathyroid carcinoma (PC), atypical neoplasm (AN) and parathyroid adenoma (PA). II. To determine which potential genes can be used in patients with parathyroid tumors for diagnostic purposes. OUTLINE: Previously collected tumor tissue and blood samples are analyzed via immunohistochemical profiling for identifying potential genes showing molecular aberrations as other types of cancer.
Inclusion Criteria: * The patient cohort for this study consists of all patients within the prospectively maintained parathyroid database within the Department of Surgical Oncology at the University of Texas MD Anderson Cancer Center (MDACC) or from collaborating sites, with tissue or blood available from 1968-2015, previously consented for the use of the tissue for research purposes (via Protocols LAB 08-0034, PA11-0695 and LAB03-0320 or the appropriate external mechanism for collaborating sites). * All patients with a known diagnoses of primary hyperparathyroidism (PHPT) operated/treated in…
