Surgical therapy for familial hyperparathyroidism.
Isolated familial hyperparathyroidism (FHPT) not associated with multiple endocrine neoplasia is a rare and aggressive form of primary hyperparathyroidism. The traditional management of FHPT is a bilateral neck exploration with an increased rate of multigland hyperplasia, supernumerary glands, and recurrence. A prospective database was queried, which included 1383 consecutive parathyroidectomies between 1992 and 2008, and 28 patients with FHPT were identified. Patient demographics, pathology, intraoperative parathyroid hormone (IOPTH) kinetics, recurrence patterns, and accuracy of localization studies were analyzed. Twenty-one patients underwent bilateral neck explorations as an initial surgery, and seven patients had nine unilateral neck explorations for recurrent hyperparathyroidism. Overall cure rate was 89.2 per cent with a mean follow-up of 2.9 years (range: 6 months to 9.2 years); 64.3 per cent of patients had multigland disease. IOPTH helped identify supernumerary glands in three (12.5%) patients and accurately lateralized recurrent disease in eight of nine surgeries (88.8%). Tc-99m-Sestamibi failed to identify multigland disease in 11 patients (52.3%). FHPT has a greater prevalence of multigland disease, decreased utility of sestamibi scanning, and a higher recurrence rate than sporadic primary hyperparathyroidism. In FHPT, IOPTH is a useful adjunct in identifying additional tumors and in select cases may play a role in tumor localization.
