Objective: To investigate the changes and clinical significance of serum tumor markers in patients with rheumatoid arthritis (RA) combined with interstitial lung disease. Methods:A total of 50 healthy volunteers were chosen as the normal control group, 47 patients with rheumatoid arthritis alone were chosen as the RA group, and 28 patients with rheumatoid arthritis combined with interstitial lung disease were chosen as combined disease group. The differences in the levels of serum tumor markers, RA markers and inflammatory mediators were compared among the three groups, and Pearson test was used to evaluate the correlation of serum tumor marker levels with RA markers and inflammatory mediators in patients with RA combined with interstitial lung disease. Results: Serum tumor markers CA199, CA153 and CEA levels of combined disease group were higher than those of RA group;RA markers RF and GPI levels were higher than those of RA group whereas CCP and AKA levels were not significantly different from those of RA group;inflammatory mediators HMGB1, GM-CSF, IL-6, IL-17 and IL-27 levels were higher than those of RA group. Correlation analysis showed that serum tumor markers CA199, CA153 and CEA levels in patients with RA combined with interstitial lung disease were positively correlated with RF, GPI, HMGB1, GM-CSF, IL-6, IL-17 and IL-27 levels. Conclusion: Serum tumor markers CA199, CA153 and CEA levels abnormally increase in patients with RA combined with interstitial lung disease, and the specific levels were directly correlated with the disease severity.
