Impact of concurrent parathyroid adenoma on the recurrence of differentiated thyroid carcinoma: a retrospective study

Abstract

Background/aim: The impact of concurrent parathyroid adenoma in differentiated thyroid carcinoma remains unclear. This study was performed to compare the recurrence rates of patients operated on for differentiated thyroid carcinoma with concomitant parathyroid adenoma and those operated on for thyroid carcinoma without detected parathyroid adenoma.Materials and methods: This retrospective study examined 340 patients who underwent total thyroidectomy for thyroid carcinoma at our institution. We compared the patients with concurrent parathyroid adenoma to those without, assessing clinical, laboratory, surgical, and histopathological findings and thyroid carcinoma recurrence over a 6-year postoperative period.Results: Among all patients, 53/340 (16%) were identified with parathyroid adenoma, predominantly over the age of 50 years (p
