Abstract:
Objective To explore the diagnostic value of combination detection of carcino‐embryonic antigen(CEA ) ,cytokeratin 19 fragment 21‐1(CYFR21‐1) ,neuron‐specific enolase(NSE) in bronchoalveolar lavage fluid (BALF) for early lung cancer and its correlation with clinical effects .Methods 69 cases of lung cancer were included into the lung cancer group and 50 cases of benign pulmonary disease were included into the lung benign disease group .All the patients were given bronchoalveolar lavage(BAL) .The chemiluminescence immunoassay was adopted to detect the levels of CEA ,CYFR21‐1 and NSE in BALF .The changes of tumor markers levels were compared between the two groups and among different clinical curative effects in the patients with lung cancer . Results The levels of CEA ,CYFR21‐1 and NSE in BALF of the lung cancer group were significantly higher than those of the be‐nign pulmonary disease group ,the difference was statistically significant (P < 0 .05) .The levels of tumor markers in the stage Ⅱ of lung cancer were higher than those in the stage Ⅰ of lung cancer ,the difference was statistically significant (P< 0 .05) ;the levels of CEA ,CYFR21‐1 and NSE in BALF were gradually increased with the decrease of clinical effect (P< 0 .05) ;the sensitivity and spe‐cificity of the combined detection of three tumor markers were 62 .3% and 82 .0% respectively ,which were significantly higher than those of any single tumor marker (P< 0 .05) .Conclusion The levels of CEA ,CYFR21‐1 and NSE in BALF of early lung cancer patients are obviously increased ,moreover which is closely correlated with the pathological stage of lung cancer ,the combined detec‐tion could contribute to improve the detection rate of early lung cancer and guide the evaluation of clinical effect .
