Abstract：Objective The aim of this study was to explore the diagnostic value of lung cancer by using CT-guided percutaneous lung biopsy combined with tumor markers.Methods We retrospectively analysed the 78 patients with lung placeholder in our hospital,using 18G semi-automatic cutting biopsy needle to obtain pathological diagnosis by Low-dose CT-guided lung biopsy,and evaluated its value in diagnosis of lung cancer combined with tumor markers.Results All of the lung biopsing were successful.The sensitivity,specificity,and accuracy for the diagnosis of lung cancer were 97.01％ 100％ and 97.82％.We found statistical significant differences of NSE positive rate lung paracentesis negative lung cancer and benign biopsy (P =0.020);but differences in lung cancer and benign biopsy negative CEA,CYFRA21-1 positive rate were not statistically significant (P =0.256,P =0.155).Conclusion Low-dose CT-guided percutaneous lung biopsy was very safe,with a few complications,which had a high diagnostic accuracy for lung cancer.Percutaneous lung biopsy combined with tumor markers can improve the diagnostic accuracy of lung paracentesis negative lung cancer.
