ABSTRACT
<p><b>OBJECTIVE</b>To study the rate of elevated common biomarkers of digestive tumors, including carcinoembryonic antigen (CEA), alpha fetoprotein (AFP), carbohydrate antigen 125 (CA125) and carbohydrate antigen 19-9 (CA19-9), in gastroenteropancreatic neuroendocrine neoplasm (GEP-NEN) and their prognostic values in GEP-NEN.</p><p><b>METHODS</b>Clinicopathological data of patients with GEP-NEN treated in The First Affiliated Hospital, Sun Yat-sen University from January 2011 to December 2016 were retrospectively studied. The inclusion criteria were as follows patients with complete clinicopathological data including AFP, CEA, CA125 and CA19-9 level before treatment; patients without previous or other concomitant cancer; patients diagnosed as sporadic but not familial NEN. Serum AFP level >30 μg/L, CEA level >7.5 μg/L, CA125 level >52.5 μg/L and CA19-9 level >52.5 kU/L were defined as elevation respectively. Kaplan-Meier analysis and Log-rank test were applied to investigate the prognostic role of these biomarkers.</p><p><b>RESULTS</b>A total of 170 patients with GEP-NEN were enrolled, and 105 (61.8%) patients were male with median age of 52.5 years. Thirty-six (21.2%), 77 (45.3%) and 57 (33.5%) cases were gastric, intestinal and pancreatic NEN respectively. Elevated AFP, CEA, CA125 and CA19-9 were found in 3(1.8%), 19(11.2%), 22(12.9%) and 21(12.4%) patients. Elevated CEA was related with G3 disease (OR=4.78, 95%CI1.28-17.85, P=0.020) and elevated CA125 was related with distant metastasis (OR=51.60, 95%CI5.76-462.44, P=0.000) while elevated CA19-9 was related with both G3 disease (OR=3.81; 95%CI1.21-11.99, P=0.022) and distant metastasis(OR=4.87; 95%CI1.41-16.75, P=0.012). The median follow-up was 22.5 months. Forty-six patients (27.1%) died during the follow-up. Patients with elevated CEA, CA125 or CA19-9 had worse overall survival compared with their counterparts with the median survivals of 14 months (95%CI5.4 to 22.6 months, χ=15.582, P=0.000), 6 months (95%CI3.2 to 8.8 months, χ=37.627, P=0.001) and 10 months (95%CI0 to 20.6 months, χ=50.187, P=0.000) respectively. Furthermore, patients with more than two elevated biomarkers (median survival 6 months, 95%CI4.37-7.63 months) had worse survival than patients with only one elevated biomarker (median survival 26 months, 95%CI15.68-36.32 months, χ=9.295, P=0.002).</p><p><b>CONCLUSIONS</b>Elevation of AFP, CEA, CA125 or CA19-9 is not common in GEP-NEN. Patients with elevation of these biomarkers have poor survival.</p>
