Abstract:
Objective:To evaluate the diagnostic values of single and combined detection of serum CA199, complement 3 (C3),complement 4 (C4),total cholesterol (TC),triglyceride (TG),and lipid metabolism levels in the patients with pancreatic cancer, and to explore their correlations with TNM stage and pathological stage of pancreatic cancer.Methods:Total 185 subjects were enrolled into the study by three groups:pancreatic cancer patients group (Pc group,n=77),non-digestive system cancer patients group (Ndc group,n=58)and healthy control group (Hc group,n=50).The levels of serum CA199,C3,C4,and high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), apolipoprotein A (ApoA), apolipoprotein B (ApoB), apolipoprotein E (ApoE),and lipoprotein a (Lpa)levels were detected.Results:① The serum level of CA199, C3,C4,and ApoE of the patients in Pc group were higher than those in Ndc and Hc groups (P<0.01).No statistical difference was observed in the serum CA199 between Ndc and Hc groups (P>0.05).The levels of C3, C4,and ApoE in Pc group and Ndc group was higher than those in Hc group (P<0.01),and the levels of the biomarkers in Pc group were also higher than those in Ndc group (P<0.01).The levels of HDL-C,ApoA and Lp (a)of the patients in Pc group were significantly lower than those in Ndc and Hc groups (P<0.05).② The area under ROC curve (AUC)of serum CA199,C3,C4,ApoE,HDL-C,and ApoA were 0.916,0.841, 0.788,0.785,0.834,and 0.810,respectively.Furthermore,multiple factor analysis showed that the combined detection of CA199,C3,and HDL-C (AUC=0.968)improved the diagnosis compared with detecting CA199 alone (P<0.05).③ The CA199 level of the patients inⅢ-Ⅳ stage of TNM stage was higher than that in the patients inⅠ-Ⅱ stage (P<0.01).For the pathological stage,the ApoA level in low differentiation group was higher than that in moderate and high differentiation group (P<0.05).There was no statistical difference in other biomarkers between the different TNM stages and pathological stages.Conclusion:The levels of CA199,C3,C4 and ApoE of pancreatic cancer patients are significantly increased, while the levels of HDL-C, ApoA, and Lp (a ) are significantly reduced.Combined detection of CA199,C3,and HDL-C can improve the early diagnosis of pancreatic cancer compared with the single assessment of each biomarker.
