Abstract:
Objective To investigate the clinical value of serum ferritin (SF) combined with 4 tumor mark-ers in the early diagnosis of lung cancer in elderly patients .Methods 185 cases of elderly patients with early-stage lung cancer as lung cancer group ,60 cases of elderly patients with benign lung disease as benign lung disease group ,50 healthy people were enrolled as healthy control group ,compared three groups of subjects of serum SF ,carbohydrate antigen 125 (CA125 ) ,carcinoembryonic antigen (CEA ) ,neuron-specific enolase (NSE) ,cytokeratin 19 fragment antigen 21-1 (CYFRA21-1) expression and sensitivity ,specificity ,ROC curve analysis of the diagnostic index value .Results CA125 ,SF ,CEA ,NSE and CYFRA21-1 in lung cancer group , were higher than those of benign lung disease group and healthy control group ,the difference was statistically significant (P＜0 .05) ;SF ,CA125 ,CEA ,NSE and CYFRA21-1 of the benign lung disease group and healthy control group ,which showed no difference (P＞0 .05) .SF and NSE were the highest in patients with small cell lung cancer ,the difference was statistically significant (P＜0 .05) ,CA125 and CEA were the highest in adeno-carcinoma patients ,the difference was statistically significant (P＜0 .05) ,and CYFRA21-1 was the highest in squamous cell carcinoma patients ,the difference was statistically significant (P＜0 .05) .Compared with the single diagnosis of each index ,the sensitivity of combined detection of the five indicators increased ,the differ-ence was statistically significant (P＜0 .05) ,while the specificity did not change ,the difference was not statis-tically significant(P＞0 .05) .The area under the ROC curve of SF ,CA125 ,CEA ,NSE and CYFRA21-1 was 0 .808 ,0 .762 ,0 .761 ,0 .712 and 0 .781 ,respectively .The area under the ROC curve of the 5 indexes was 0 .915 . Conclusion Serum ferritin combined with 4 tumor markers can improve the diagnostic sensitivity of early eld-erly patients with lung cancer ,and effectively improve the diagnostic value of patients ,thereby contributing to the improvement of the clinical prognosis of patients .
