Long Term Parathyroid Function Following Total Parathyroidectomy with Autotransplantation in Adult Patients with MEN2A

[摘要] References(23)Cited-By(3)While there is no doubt that total thyroidectomy is necessary for medullary thyroid carcinoma (MTC) in multiple endocrine neoplasia type 2A (MEN2A) patients, there is still controversy regarding the management of the parathyroid glands. Although most, but not all, endocrine surgeons leave normal-appearing parathyroid glands in situ during thyroid surgery for MEN2A, we have employed total parathyroidectomy with autotransplantation. Between 1994 and 2006, 12 MEN2A patients underwent therapeutic total or completion thyroidectomy and lymph nodes dissection at least in the central compartment for MTC. Total or completion parathyroidectomy with autotransplantation was performed concurrently with above-mentioned surgery. All patients were over 25 years old, and the median age was 48.5 years. There were 5 males and 7 females from 8 families. The average number of transplanted parathyroid glands was 3. Serum calcium and intact PTH levels have been maintained during the median follow up of 107 months in all patients except for one who of died of advanced MTC one year after surgery. Total parathyroidectomy with autotransplantation at the time of primary surgery for MTC, i.e. total thyroidectomy with bilateral central neck dissection, is a feasible approach for managing the risk of hyperparathyroidism.
