Early changes in parathyroid function after high-dose irradiation of the neck

Abstract
Hyperparathyroidism (HPT) will develop years later in a number of patients irradiated to the neck for benign diseases. Twenty‐nine patients with malignant diseases were studied for 3 years after irradiation with cancer therapeutic doses to the neck. The serum concentration of parathyroid hormone (iPTH) showed an increasing trend suggesting that HPT also might develop in these patients.
