Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The primary objective of this study is to estimate the percent change in baseline bone mineral density (BMD) starting at one year after parathyroidectomy and all the following available dates in patients presenting with primary hyperparathyroidism. The secondary objective is to identify patient factors associated with change in BMD.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Parathyroidectomy Data Review

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.

Retrospective Data Review

Intervention Type OTHER

Retrospective, uncontrolled pre- and post-test design in a case series of approximately 250 patients who underwent parathyroidectomy at MD Anderson Cancer Center (years 1990 - 2013 ) and had bone density measures recorded at baseline and at one year post-surgery. Data extracted from the surgical oncology database for bone mineral density measures for each patient at multiple sites including the lumbar spine, total hip (right/left), femoral neck (right/left), and distal 1/3 radius. All measures recorded from two time points: presurgical (baseline) and postsurgical (all follow-up available dates beginning at 1 year post-parathyroidectomy).
