Diagnostic value and correlation of multiple tumor markers in pancreatic cancer / 中国免疫学杂志

ABSTRACT

Objective:To explore the diagnostic value and correlation of serum tumor markers combined detection of pancreatic cancer. Methods:Selected January 2013 to may 2016 in our hospital in patients with pancreatic cancer in 146 cases,128 cases of non pancreatic cancer with patients and 124 cases of healthy physical examination. Radiation immunity analyzer test groups of serum CA19-9,CA242,CA50,CA125,CEA and TSGF levels and compared between groups. To draw the working characteristic curve(ROC) to analyze the diagnostic value of tumor markers in patients with pancreatic cancer and the correlation of linear correlation analysis of tumor markers. Analysis of independent risk factors for pancreatic cancer using multiple logistic regression models. Results: The pancreatic cancer group of serum CA19-9,CA242,CA50,CA125,CEA and TSGF levels were significantly higher than the control group and non pancreatic cancer group,the differences were statistically significant(P<0. 05 or P<0. 01).Ⅳstage andⅢstage with patients of serum CA19-9,CA242,CA50,CA125 and TSGF levels were significantly higher than Ⅰstage and Ⅱstage with patients(P<0. 01).Ⅳ stage with patients of serum CA19-9, CA242, CA125 and CEA levels were significantly higher than Ⅲ stage with patients ( P<0. 01). The pancreatic cancer group of serum CA19-9,CA242,CA50,CA125,CEA and TSGF of positive rate were significantly higher than that of control group and non pancreatic cancer group(P<0. 01). ROC curves showed that the AUC of serum CA19-9 were higher than other single indexes,the best critical value,sensitivity and specificity were 114. 5 U/ml,81. 2% and 79. 3% respectively. The diagnostic efficacy of the six joint detection were better than the single detection,the sensitivity and specificity were 92. 4% and 76. 5%respectively. Correlation analysis showed that serum CA19-9 were positively correlated with CA242,CA50 and CA125(r=0. 703,P=0. 005;r=0. 572,P=0. 024;r=0. 439,P=0. 036). Multiple logistic regression analysis showed that smoking,incorrect diet,history of diabetes,gallbladder disease history and high levels of CA19-9,CA242,CEA into the regression model,the OR value and 95%CI were 1. 717(0. 736 to 2. 359),2. 865(2. 217 to 3. 685),2. 614(2. 186 to 3. 127),3. 527(2. 842 to 4. 377),4. 214(3. 570 to 4. 962), 2. 315(2. 114 to 2. 539),1. 876(1. 175 to 2. 852). Conclusion: Serum tumor markers combined detection can help to improve the accuracy of early diagnosis of pancreatic cancer and smoking,incorrect diet habits,history of diabetes,biliary disease history and high levels of CA19-9,CA242 and CEA are independent risk factors for pancreatic cancer.
