The research plan is for a retrospective review to be performed of a prospectively maintained parathyroid database within the Department of Surgical Oncology at the University of Texas MD Anderson Cancer Center. The patient cohort for this study consists of all patients with primary hyperparathyroidism who underwent parathyroidectomy and also had pre- and post-operative DEXA studies performed. The database will be reviewed to obtain patient and disease characteristics, laboratory values, DEXA imaging results, and surgical outcomes.
