Clinical research on lung cancer diagnosed by fiberoptic bronchoscopy

Objective To evaluate the value of fiberoptic bronchoscopy in diagnosing lung cancer.Methods 180 patients of lung cancer underwent conventional bronchoscopy to confirm diagnosis and pathological type by forceps biopsy,brush biopsy and bronchoalveolar lavage techniques.Results 160 patients were diagnosed with lung cancer by pathological examination,in which 127 cases were central lung cancer and 33 cases were peripheral lung cancer.20 patients whose pathological examination was false-negative were finally diagnosed by the surgery,cytology or biopsy in other hospital,in which 5 cases were central lung cancer and 15 cases were peripheral lung cancer.The percentage of Squamous cell carcinoma was 50%,adenocarcinoma was 27.22%,Small cell carcinoma was 17.22%,other types was 5.56%.Conclusion Fiberoptic bronchoscopy is a valuable methed in diagnosing lung cancer,and the biopsy approach combined with forceps biopsy,brush biopsy and bronchoalveolar lavage techniques was significant different than the single biopsy method(P0.05).It can improve the positive rate of pathological examination,and provide the basis for clinical treatment.
