Abstract: Objective The aim of the study was to investigate the relationship between the serum levels of tumor markers and histopathological types of bronchoscopy biopsy.Methods A retrospective study was performed in 356 lung cancer patients who underwent bronchoscopy biopsy at Harbin Medical University Cancer Hospital from January 2013 to December 2018 and completed the detection of related serum tumor markers(SCCA,CYFRA21-1,CEA,CA125 and NSE).Patients with lung cancer(140 small cell carcinoma,122 squamous cell carcinoma and 94 adenocarcinoma)were retrospectively analyzed.Results In lung cancer patients with bronchoscopy biopsy,the combination of five serum tumor markers(SCCA+CYFRA21-1+CEA+CA125+NSE,AUC=0.948,P<0.001)had a high value in assisting the diagnosis of small cell carcinoma and non-small cell lung cancer;three(SCC+CEA+ NSE,AUC=0.901,P<0.001)or four(SCC+CYFRA21-1+CEA+NSE,AUC=0.901,P<0.001)markers combined to distinguish squamous cell carcinoma and adenocarcinoma were more accurate.The value of the three marker combination(SCCA+CEA+CA125,AUC=0.831,P<0.001)had a high value of diagnosis.Conclusion For lung cancer patients with different pathological types,the combination of different serum tumor markers has certain auxiliary diagnostic value for pathological types under bronchoscopy biopsy.
