Background:
This study was undertaken to determine the optimal thyroid-stimulating hormone (TSH) value associated with structural recurrence in patients with low-risk or intermediate-risk papillary thyroid carcinoma (PTC) who underwent thyroid lobectomy.
Methods:
Patients with PTC (n = 1047) who received thyroid lobectomy and central compartment node dissection were included in the study.
Results:
Structural recurrence occurred in 42 of the patients (4.0%), and no patient died of PTC. Multivariate analysis showed a primary tumor size (with a cut-off of 0.85 cm) and serum TSH level measured 1 year after the initial surgery (cut-off 1.85 mU/L) independently predicted structural recurrence.
Conclusions:
TSH levels during the early postoperative period need to be monitored and maintained in the lower normal range even in patients with low- or intermediate-risk PTC undergoing thyroid lobectomy.

Functions of Thyroid Hormones
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...
Synthesis and Regulation of Thyroid Hormones
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...
