Significance of C-ROSE after EBUS-TBNA sampling combined with lung serum tumor markers in pathological classification and classification transformation of lung cancer
Objective:To explore the benefits of combining C-ROSE with pulmonary serum tumor markers for lung cancer pathologic classification and classification transformation.Methods:A total of 125 patients who underwent C-ROSE examination after EBUS-TBNA sampling in our hospital from October 2021 to July 2023 were collected,including 33 cases of lung squamous cell carcinoma(LUSC),40 cases of lung adenocarcinoma(LUAD),11 cases of large cell poorly differentiated lung carcinoma(LCLC)and 41 cases of small cell poorly differentiated lung carcinoma(SCLC).The diagnostic positive rates of C-ROSE and lung serum tumor markers were compared in different patho-logical types of lung cancer after EBUS-TBNA sampling alone or in combination.Results:C-ROSE can improve the sampling qualification rate of LUSC(72.7%),LUAD(85.0%),LCLC(63.6%),SCLC(53.1%)and other types of lung cancer(P<0.05).At the same time,SCCAg was the dominant lung serum tumor marker in LUSC(sensitivity 87.9%,specificity 82.6%,AUC=0.907,P<0.05),and C-ROSE combined with SCCAG could increase the positive rate of diagnostic efficacy(87.9%,P<0.05).CEA was the dominant pulmonary serum tumor marker in LUAD(sensitivity 62.5%,specificity 80.0%,AUC=0.733,P<0.05).Combined with C-ROSE could increase the positive rate of diagnostic efficacy(97.5%,P<0.05).ProGRP+NSE was the dominant serum tumor marker in SCLC(sensitivity 85.4%,specificity 95.2%,AUC=0.943,cut-off=134.94,P<0.05).ProGRP+NSE combined with C-ROSE can improve positive rate of the diagnostic efficacy(90.2%,P<0.05).The diagnostic value of NSE/ProGRP was the highest in LCLC(sensitivity 90.9%,specificity 82.9%,AUC=0.894,cut-off=0.332,P<0.05).The combination with C-ROSE could improve the positive rate of diagnostic efficacy(100.0%,P<0.05).Conclusion:After EBUS-TBNA sampling,C-ROSE combined with lung serum tumor markers can improve the positive rate of early diagnosis of different pathological types of lung cancer and help to warn the type change.
