Abstract: Objective:
A regular collection of cytology specimens from bronchoalveolar washing is expected to increase the ability of bronchoscopy to diagnose lung cancer. However, we aimed to study the sensitivity of cytology washing tests for diagnosing malignant lung lesions.

Methods:
This is a retrospective study including 68 patients who underwent different thoracic surgeries for lung cancer in St. Vincent University Hospital from June 2013 to March 2020. The results of all cytology specimens from bronchoalveolar washing were reviewed from the patients' files.

Results:
Out of 68 patients, the predominant type of lung cancer was adenocarcinoma (54.4%) and squamous cell carcinoma (22.2%). Most of the patients were in stage I (67.6%). The positive cytology result as malignant cells was shown in 5 patients (7.4%). Also, another 5 patients (7.4%) had atypical cells.

Conclusion:
The value of cytology specimens from bronchoalveolar washing in this study was not significant. This may be due to increasing the incidence of adenocarcinomas. Eliminating this technique could be considered in centers with similar experiences.

Key Words: cytology, lung cancer, sensitivity.
