- Abstract: Objective To investigate the expression of serum tumor-associated antigens(TAAs)in patients with rheumatoid arthritis(RA)and analyze their clinical significance for RA.Methods A total of 214 RA patients were enrolled in the RA group,while 198 age-and gender-matched healthy individuals were included in the HC group.Rheumatoid factor(RF),anti-cyclic citrullinated peptide antibody(Anti-CCP),C-reactive protein(CRP),erythrocyte sedimentation rate(ESR),interleu-kin-6(IL-6),ferritin levels,as well as gender,age,disease duration,disease activity score(DAS28)and clinical manifestations were collected from the RA group.The expression of TAAs in RA patients and the clinical characteristics of TAA-positive patients were analyzed.Spearman correla-tion analysis was used to evaluate the relationships between TAAs and clinical indicators in RA pa-tients.Results The positive rate of carbohydrate antigen 125(CA125)in the RA group was 8.88％,which was significantly higher than 1.01％ in the HC group(P＜0.001).Serum CA125 and cytok-eratin fragment 19(CYFRA21-1)levels in the RA group were significantly higher than those in the HC group,whereas alpha-fetoprotein(AFP),carcinoembryonic antigen(CEA),carbohydrate anti-gen 199(CA199)and neuron-specific enolase(NSE)levels were significantly lower(P＜0.001).TAA-positive patients had significantly older age and higher rates of pulmonary interstitial lesions compared to TAA-negative patients(P＜0.05).Patients with DAS28 scores＞5.1 had significantly higher CA125 levels than those with DAS28 scores ≤5.1(P＜0.05).CA125 levelswere positively corre-lated with DAS28 scores,ESR,RF,and anti-CCP antibodies(r=0.142,0.140,0.268,0.183;P＜0.05).Conclusion In RA patients,the positivity rate and levels of some serum TAAs are ele-vated,and TAA-positive patients tend to be older and have higher incidence of pulmonary interstitial lesions.CA125 levels are positively correlated with RA disease activity.
