Primary hyperparathyroidism (PHPT) is defined by autonomous parathyroid hormone secretion, which has broad physiologic effects. Parathyroidectomy is the only cure and is recommended for patients demonstrating symptomatic disease and/or end organ damage. However, there may be a benefit to intervening before the development of complications. We sought to characterize institutional trends in the biochemical and symptomatic presentation of PHPT and the associated cure and complication rates.
We performed a retrospective cohort study of 1087 patients undergoing parathyroidectomy for PHPT, evaluating patients at 2-year intervals between 2002 and 2019. We identified signs and symptoms of PHPT based on the 2016 American Association of Endocrine Surgery Guidelines. Trends were evaluated with Kruskal Wallis, Chi-square tests, and Fisher's exact tests.
Patients with PHPT are presenting with lower parathyroid hormone (P = 0.0001) and calcium (P = 0.001) in the current era. Parathyroidectomy is more commonly performed for borderline guideline concordant patients with osteopenia (40.2%) and modest calciuria (median 246 mg/dL/24 h). 93.7% are cured, with no difference over time or between groups by guideline concordance.
Parathyroidectomy is increasingly performed for patients who demonstrate modest bone and renal dysfunction. Patients experience excellent cure rates and rarely experience postoperative hypocalcemia, suggesting a role for broader surgical indications.
