Surgery for Primary Hyperparathyroidism (pHPT) in Patients Older Than 65 Years Compared With Follow-up

The majority of patients diagnosed and operated due to primary HPT in Scandinavia are older than 65 years of age. The vast majority of the patients have mild aberrations of serum calcium (\< 1.50 mmol/l ionized calcium), and some patients may even be asymptomatic. The present trial is designed to clarify the indications for surgical treatment in this large subgroup of patients.
