The Effect of TSH Suppression Therapy on the Efficacy and Immune Function of Postoperative Patients with Thyroid Cancer

Abstract

Objective: To investigate the efficacy and immune function of thyroid stimulating hormone (TSH) suppression therapy in postoperative thyroid cancer patients. Methods: Sixty thyroid cancer patients admitted from July 2020–July 2022 were recruited and randomly divided into two groups. The control group (30 patients) received hormone replacement therapy, while the study group (30 patients) received TSH suppression therapy. The thyroid function, clinical efficacy, immune function, and tumor markers of the two groups were compared. Results: After treatment, the levels of free triiodothyronine (FT3) and thyroxine (FT4) in both groups increased significantly, while TSH levels decreased significantly. Moreover, the magnitude of change in the study group was greater than that in the control group (P < 0.05). The total effective rate in the study group was significantly higher as compared to the control group (P < 0.05). After treatment, the levels of CD3+ and CD4+ cells in both groups of patients increased significantly, with the study group showing significantly higher levels than the control group, whereas the level of CD8+ cells decreased significantly, with the study group having lower levels than the control group (P < 0.05). After treatment, the levels of Tg and CEA in both groups were significantly lowered as compared to before treatment, and the levels of Tg and CEA in the study group were significantly lower than the control group (P < 0.05). Conclusion: TSH suppression therapy in postoperative thyroid cancer patients can improve thyroid function, suppress the levels of tumor markers, and enhance immune function, thereby achieving good clinical outcomes.
