Patients with primary hyperparathyroidism (PHPT) can present with variable signs, symptoms, and end-organ effects. Clinical practice guidelines influence referral for consideration of parathyroidectomy.
This study compared the demographic, biochemical, and symptom profile and examine indications for surgery in patients older than 50 years who underwent parathyroidectomy to determine how changes to current guidelines may affect recommendations for parathyroidectomy.
A retrospective review was conducted of patients age 50 years or older who underwent initial parathyroidectomy for sporadic PHPT from 2012 to 2020. Patients were classified by indications for surgery per guideline criteria (classic, asymptomatic, and no criteria met) and age group (AG): 50 to 59 years; 60 to 69 years; 70 years or older. Patients were treated at a high-volume tertiary medical center by endocrine surgeons.
Of 1182 patients, 367 (31%) classic and 660 (56%) asymptomatic patients met the criteria for surgery. The most common indications for surgery were extent of hypercalcemia (51%), osteoporosis (28%), and nephrolithiasis (27%). Of the 155 (13%) patients who did not meet the criteria, neurocognitive symptoms (AG1: 88% vs AG2: 81% vs AG3: 70%; P = .14) and osteopenia (AG1: 53% vs AG2: 68% vs AG3: 68%; P = .43) were frequently observed regardless of patient age. If the age threshold of younger than 50 years was expanded to 60, 65, or 70 years, an additional 61 (5%), 99 (8%), and 124 (10%) patients in the entire cohort would have met the guideline criteria for surgery, respectively.
Expanding current guidelines for PHPT to include a broader age range, osteopenia, and neurocognitive symptoms may allow for earlier surgical referral and evaluation for definitive treatment.
