  Purpose
The main purpose of this research study is to evaluate the effectiveness of a minimally invasive surgical approach to removing parathyroid gland(s). The researchers are also interested in analyzing abnormal parathyroid tissue for changes in genes and proteins that may contribute to overactive parathyroid gland(s).

Condition Intervention
Primary Hyperparathyroidism Procedure: Minimally invasive radioguided parathyroidectomy

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Cross-Sectional
Official Title: Minimally Invasive Radioguided Parathyroidectomy

Further study details as provided by Michael B. Flynn, MD, University of Louisville:

Primary Outcome Measures:
  • The positive and negative predictive value of sestamibi scanning to detect parathyroid adenomas. [ Time Frame: 2-3days ]

Secondary Outcome Measures:
  • The value of intraoperative parathyroid hormone assay to verify biochemical cure or primary hyperparathyroidism [ Time Frame: 2-3 days ]
  • Collection of abnormal parathyroid tissue at the time of surgery for tissue analysis [ Time Frame: day of surgery (1 day) ]

Biospecimen Retention:   Samples With DNA
Small portion of abnormal parathyroid gland that is removed during surgery is frozen and stored for future research.

Enrollment: 856
Study Start Date: September 1998
Study Completion Date: April 2017
Primary Completion Date: December 2009 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Parathyroid surgery
Database of patients who have undergone minimally invasive radioguided parathyroidectomy
Procedure: Minimally invasive radioguided parathyroidectomy
After the patient is prepared for surgery and under local anesthesia, the initial incision by the surgeon will be 2-3 cm. The surgeon will dissect in the designated quadrant until the parathyroid gland is identified.

Detailed Description:
The specific aims of this study are to determine the safety and efficacy of minimally invasive radioguided parathyroidectomy, to determine the positive and negative predictive value of sestamibi scanning to detect parathyroid adenomas, and to differentiate adenomas from parathyroid hyperplasia. In addition, this study aims to determine the value of intraoperative parathyroid hormone assay to verify biochemical cure of primary hyperparathyroidism, to determine whether minimally invasive radioguided parathyroidectomy is cos-effective, and to collect abnormal parathyroid tissue at the time of surgery for tissue analysis.
