    Background:
    This prospective study was designed to investigate the association between multiple inflammatory biomarkers in circulation and the risk for early stage lung adenocarcinoma.
    
    Methods:
    We measured 10 inflammatory biomarkers in 228 early stage lung adenocarcinoma patients and 228 age, sex and smoking matched healthy controls by using the Luminex bead-based assay.
    
    Results:
    Only two biomarkers were significantly associated with early stage lung adenocarcinoma risk after Bonferroni correction: the multivariate odd ratio or OR (95% confidence interval or CI) was 0.29 (0.16-0.53) for MDC/CCL22 (P<0.0001) and 4.17 (2.23-7.79) for BLC /CXCL13 (P<0.0001) for the comparison of 4[th] quartile with 1[st] quartile. When analysis was restricted to never smokers (196 patients/196 controls), MDC/CCL22 and BLC/CXCL13 were still significantly associated with early stage lung adenocarcinoma risk (OR; 95% CI; P: 0.37; 0.21-0.66; P<0.0001 for MDC/CCL22 and 2.78; 1.48-5.22; P =0.001 for BLC/CXCL13). Additionally, significance persisted after restricting analysis to 159 stage IA lung adenocarcinoma patients and 159 matched controls for MDC/CCL22 (OR; 95% CI; P: 0.37; 0.21-0.66; <0.0001) and BLC/CXCL13 (2.78; 1.48-5.22). Furthermore, elevated BLC/CXCL13 was associated with a 2.90-fold (95% CI: 1.03-8.17; P=0.037) increased risk of subcentimeter lung adenocarcinoma, and there was an increasing trend for BLC/CXCL13 with the progression of subcentimeter lung adenocarcinoma.
    
    Conclusion:
    Our findings demonstrated that MDC/CCL22 and BLC/CXCL13 were independently associated with the significant risk of early stage lung adenocarcinoma, and this association persisted even in non-smokers and in stage IA patients. Moreover, BLC/CXCL13 was identified to play a carcinogenic role in the progression of lung adenocarcinoma.
