BACKGROUND: We investigated if anatomic patterns of abnormal parathyroid glands have ch anged for primary hyperparathyroidism (pHPT) as atypical biochemical presentation (normohormonal and normocalcemic) has increased.
METHODS: Retrospective review of patients with pHPT who underwent routine bilateral neck exploration.
RESULTS: 2762 patients were included. The "late" cohort (2014-2020) exhibited lower preoperative calcium (10.8 vs 11.1 mg/dL; P = 0.001) and PTH levels (101 vs. 146 pg/mL; P = 0.001) compared to the "early" cohort (2000-2006). Patients with atypical biochemical profiles increased from 25.5% to 31.3% (P < 0.001). The prevalence of single adenoma (SA) decreased (66.1% vs 58.9%, P = 0.02) while the proportion of double adenoma (DA) increased (17.3% vs. 22.6%, P < 0.01). Upper parathyroid adenoma(s) remained the most common finding for SA and DA in both time points.
CONCLUSIONS: Despite changes in patient characteristics, single upper adenoma and bilateral double upper adenomas remain the most common findings for patients with pHPT.
