DNA aneuploidy analysis of bronchial washing from the target bronchial segment were performed. The clinical information, R\u2010EBUS data, pathological results and DNA image cytometry (DNA\u2010ICM) results were collected. For patients who did not have a clear diagnosis after bronchoscopy, follow\u2010up data was recorded.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 42 cases were included. Thirty patients had confirmed malignant tumor of the lung, 19 of which were confirmed by pathology after bronchoscopy, and 11 cases were confirmed later by surgery or percutaneous lung puncture. Twelve patients were finally considered to have benign lesions. The sensitivity of R\u2010EBUS is 63.3% and the specificity is 100%. DNA\u2010ICM has a sensitivity of 76.7% and a specificity of 91.7%. When combined, they have a sensitivity of 90%, and specificity 91.7%. As for malignant lesions, we further analyzed smoking, the size and location of lesions on chest CT, the number of aneuploid cells and the maximum value of DNA content. The results indicated that increased number of aneuploid cells or increased max value of DNA content may predict higher probability of malignancy.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>DNA\u2010ICM combined with R\u2010EBUS can improve the diagnostic sensitivity of malignant peripheral lung lesions. Increased number of aneuploid cells or increased max value of DNA content may indicate that the lesions are more likely to be
