Abstrakt: Background: Information on thyroid tumors is scant in patients with primary hyperparathyroidism (HPT) and history of head and neck irradiation. The study objective was to investigate thyroid pathology in primary HPT patients with irradiation history presenting for parathyroidectomy.
Methods: A prospective database of 1,020 parathyroidectomy patients was analyzed. 916 consecutive HPT patients were identified. History of radiation, neck ultrasound results, thyroid operations, and pathology was assessed. Patients with radiation history were compared to those with no radiation.
Results: Of the 916 HPT patients, 49 (5%) had a history of radiation and were more likely to have nodular thyroid disease (95% vs 52%), undergone a prior thyroidectomy (29% vs 4%), or had concurrent thyroidectomy (49% vs 26%). Nine of 49 (24%) had thyroid cancer. Of the 867 patients with no history of radiation, 259 underwent thyroid resection (32 prior and 227 concurrent) and 32 (12%) had thyroid cancer.
Conclusion: Primary HPT patients with head and neck irradiation presenting for parathyroidectomy had marked increase in nodular thyroid disease: nearly 1 in 2 had concurrent thyroidectomy, and nearly 1 in 4 had thyroid carcinoma. High resolution ultrasound prior to parathyroidectomy detects associated thyroid pathology and allows the surgeon to plan the extent of thyroid resection.
