Abstract
Objective
The purpose of this study was to evaluate the diagnostic value of transbronchial lung biopsy (TBLB) in peripheral lung cancer.
Methods
78 cases of peripheral lung cancer which could not be observed by bronchoscope were selected from the Second Affiliated Hospital of Sun Yat-sen University (China), of which 42 cases were diagnosed by TBLB. Among the 36 cases of peripheral lung cancer that could not be able to be diagnosed by TBLB, 22 cases were diagnosed by percutaneous lung biopsy (PNLB) and 14 cases being left were diagnosed by surgical specimens biopsy, lymphadenopathy biopsy, pleural biopsy or pleural effusion cytology.
Results
The positive rates produced by TBLB and transbronchial brush biopsy were 53.8% and 8.9%, respectively, and the combined positive rate was 57.7%. The positive rate produced by TBLB was higher than that of transbronchial brush biopsy (P < 0.01). As the tumor’s diameter increased, the positive rate of the biopsy was higher (P < 0.05). The positive rate of biopsy of the right lung was not significantly higher than that of the left lung (P > 0.05). The positive rate of biopsy of the inferior lobes was not significantly higher than that of the upper lobes of the lung (P > 0.05). The lesions of the tumors which were nearer to the infield and hilar of the lung got a higher positive rate (P < 0.01). The incidence of complications in PNLB was much higher than that in TBLB (P < 0.05).
Conclusion
TBLB is an important method in the diagnosis of peripheral lung cancer. Combination of TBLB and other methods can increase the positive rate in the diagnosis of peripheral lung cancer.
