Detection of chitinase 3-like 1 combined with other biomarkers for diagnosis of pancreatic cancer / 南方医科大学学报

ABSTRACT

<p><b>OBJECTIVE</b>To assess the value of chitinase 3-like 1 (CHI3L1) alone or in combination with other biomarkers in the diagnosis of pancreatic cancer.</p><p><b>METHODS</b>Serum samples were collected from 70 patients with pancreatic cancer and 31 healthy subjects and the levels of CHI3L1, CA199, C3, C4, high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein-cholesterol (LDL-C) in serum were detected.</p><p><b>RESULTS</b>The serum samples from pancreatic cancer patients showed significantly higher CHI3L1, CA199, C3, C4, HDL-C, and LDL-C levels than those from healthy subjects (P<0.05). In patients with pancreatic cancer, serum CHI3L1 level was significantly correlated with the administration of anti-cancer therapy (P<0.05), but not with gender, age, metastasis or other clinicopathological parameters (P<0.05). ROC curve analysis showed that serum CHI3L1, CA199, C3, C4, HDL-C, and LDL-C all had diagnostic value for pancreatic cancer. Multivariate analysis suggested that the combined detection model of CHI3L1, CA199, C3, and HDL-C (AUC=0.964) had a greater diagnostic value than CA199 (AUC=0.896) alone and the combined detection model consisting of CA199, C3, and HDL-C (AUC=0.923; P<0.05).</p><p><b>CONCLUSION</b>Serum levels of CHI3L1, CA199, C3, C4, HDL-C, and LDL-C all have diagnostic value for pancreatic cancer, and the combined model consisting of CHI3L1, CA199, C3, and HDL-C have greater diagnostic efficacy than the other biomarkers either alone or in combination.</p>
