Analysis of the clinical value of hsa_circ_0001955 in papillary thyroid cancer treated with 131 iodine

Background: The prevalent histological variant within differentiated thyroid carcinoma is papillary thyroid carcinoma, also known as PTC. The study investigated the clinical performance of serum hsa_circ¬_0001955 in predicting the prognosis of PTC treated with radical thyroidectomy and iodine 131 nail clearance. Method: The relative expression of serum circ_0001955 of PTC patients was detected before and after accepting radical thyroidectomy combined with 131I thyroid remnant ablation by RT-qPCR. Serum thyroglobulin (Tg) and thyroglobulin antibody (TgAb) levels were quantified by an automatic chemiluminescence immunoassay analyzer. Multivariate logistic regression analysis was employed to investigate the risk factors associated with the prognosis of PTC patients with postoperative 131I therapy. Results: The serum circ_0001955 levels in 127 PTC patients were higher than that in 96 multinodular goiter patients and 110 healthy controls before treatment and had diagnostic values for PTC patients. After 131I treatment, serum circ_0001955 levels and Tg value have a correlation with potential recurrence (WBS positive). Serum circ_0001955, Tg, and TgAb value, and their combination may have diagnostic value in predicting recurrence. Conclusion: Serum circ_0001955 levels in patients with PTC after radical thyroidectomy and iodine 131 thyroidectomy may help predict recurrence.
