Diagnostic Value of Transbronchial Ultrasound-guided Needle Aspiration Biopsy in the Diagnosis of Small Cell Lung Cancer and Non-small Cell Lung Cancer

This article evaluated the accuracy and sensitivity of EBUS-TBNA in the diagnosis of SCLC and NSCLC. Methods From January 2012 to December 2018, the clinical data of 85 patients with SCLC and NSCLC who performed EBUS-TBNA in Xuan Wu Hospital CMU were retrospectively analyzed and the differences between the two groups were compared. Results 45 cases of SCLC were confirmed by immunohistochemistry and pathology. 42 cases of SCLC were diagnosed by EBUS-TBNA. The accuracy and sensitivity of diagnosis were 93.3% (42/45) and 100.0% (42/42), respectively. The positive rate of diagnosis was 48.9% (22/45) in 22 cases diagnosed by cytology, and 40 cases diagnosed by pathology, including 35 cases diagnosed by EBUS-TBNA. The accuracy and sensitivity of diagnosis were 87.5% (35/40) and 100.0% (35/35), respectively. The positive rate of diagnosis was 27.5% (11/40) in 11 cases diagnosed by cytology. The diagnostic sensitivity of EBUS-TBNA in SCLC group was significantly higher than that in NSCLC group (P
