title: [Application of ThinPrep cytology test in the diagnosis of lung cancer].
abstract: OBJECTIVE
  To explore the diagnostic value of ThinPrep cytology test (TCT) in lung cancer.
  
  
  METHODS
  353 cases of bronchoalveolar lavage fluid (BALF) and(or) bronchial brushing cytology (192 cases from lung cancer patients and 161 cases from benign lung disease patients) were detected with TCT and method of direct smear, respectively. The sensitivity and specificity of two methods was compared.
  
  
  RESULTS
  The sensitivity and specificity of TCT were 39.6% and 99.4%. And which of direct smear method were 8.3% and 100%, respectively. The sensitivity of TCT was significantly higher than that of method of direct smear in the diagnosis of lung cancer (P < 0.01). There were 71 patients who underwent BALF and bronchial brushing cytology simultaneously, the sensitivity of TCT of BALF was higher than that of bronchial brushing cytology (P < 0.05). Of the 69 cases which had both TCT and histopathological results, TCT and pathology concordance rate was 84.1%.
  
  
  CONCLUSIONS
  TCT has more diagnostic value in lung cancer; BALF is more preponderant than bronchial brushing cytology by TCT in the diagnosis of lung cancer.
