Expression and correlation of cycde-2 protein and nuclear factor kB in serum of patients with papillary thyroid carcinoma

Abstract

To determine the clinical prediction role of the serum level of cyclooxygenase-2 (COX-2) and nuclear factor-κB (NF-κB) in papillary thyroid carcinoma (PTC) patients. 60 cases of PTC from February 2015 to May 2017 were collected to perform retrospective analysis and 10 patients with normal thyroid function were included as control group. We detected two immune factors: COX-2 and NF-κB in serum and analyse its relation to disease-free survival, overall survival, clinicopathological of PTC. COX-2 expression was associated with tumor tissue grade (p = 0.029), which was more abundant in III or IV stage (p = 0.087) patients. Relative to control group, PTC patients exhibited low NF-κB level. Survival analysis showed that the total survival time and disease-free survival time of low NF-κB level was shorter than that of control group (p < 0.05). Low COX-2 expression was associated with highly differentiated tumors (p = 0.015). However, COX-2 expression exerted little link with tumor grade, type, recurrent, age and clinical stage of PTC (p > 0.05).Further, regression analysis showed COX-2 and NF-κB expression is a risk factor for PTC, affecting prognosis. PTC patients exhibited low COX-2 and NF-κB expression, proving to correlate with the PTC development.
