Clinical application of the SurePath liquid-based Pap test in cytological screening of bronchial brushing for the diagnosis of lung cancer

摘要

The SurePath liquid-based Pap test (LPT) is successfully and widely used to assess sputum cytology. This study aimed to compare the cytological findings and diagnostic sensitivity of LPT with those of the conventional Pap smear (CPS) method for diagnosing lung cancer. Bronchial brushing specimens from 204 patients diagnosed with lung cancer were studied. LPT slides showed decreased areas of cell monolayers, a clearer background and distinct, stereoscopic cytological features. The LPT had a significantly higher diagnostic sensitivity for lung cancer (71.6%) than the CPS method (57.8%, p?2?cm lesions (p?2?cm lesions (81.4%) compared with the CPS method alone (p?
