BACKGROUND: As a new technique developed in recent years, endobronchial ultrasound guided transbronchial needle aspiration (EBUS-TBNA) has the advantages of simple operation, minimal invasive, high accuracy, safety and repeatability. It has become a new standard for lung cancer diagnosis and mediastinal staging. Because small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC) have different biological characteristics and treatment methods, it is very important to diagnose and differentiate the types of lung cancer in the early stage of lung cancer for the staging, treatment and prognosis of 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<0.05). CONCLUSIONS: EBUS-TBNA is more sensitive in the diagnosis of SCLC than NSCLC. As a minimally invasive technique, EBUS-TBNA can assist SCLC in early diagnosis and timely treatment.
