Department of Clinical Laboratory, The Second Affiliated Hospital of Southeast University

摘要

摘要:
目的比较高尔基蛋白73（GP73）、甲胎蛋白异质体3（AFP-L3）、甲胎蛋白（AFP）和α-L-岩藻糖苷酶（AFU）在不同肝脏疾病患者中的意义及其单项或联合检测诊断肝癌的价值。方法对2013年1-12月收治的272例肝癌患者、203例肝硬化患者、248例慢性肝炎患者及210例健康体检者血清中的GP73、AFP-L3、AFP和AFU水平进行检测。非正态分布的数据多组间比较采用Kruskal-Wallis H检验,组间两两比较采用Mann-Whitney U检验,率的比较用卡方检验。ROC曲线绘制分别以健康人组和非肝癌组（健康体检、慢性肝炎、肝硬化）为对照。联合指标先进行Logistic拟合后再做ROC曲线。结果 GP73水平肝硬化组[177.0（116.0,247.0）ng/ml]较肝癌组[141.0（83.3,218.8）ng/ml])和慢性肝炎组[151.0（83.0,235.3）ng/ml]高（U=22 116.5、21 052.0,P均<0.05）;AFP-L3和AFP在肝癌组中的水平[11.3（4.3,21.2）%,78.4（7.1,2455.8）ng/ml]明显高于肝...

Abstract:
Objective To compare the levels of Golgi glycoprotein 73 (GP73) , alpha- fetoprotein heterogeneity 3 (AFP- L3) , alpha-fetoprotein (AFP) , and α- L- fucosidase (AFU) between patients with different liver diseases and the diagnostic value of any or a combination of these makers for liver cancer.Methods The 272 patients with liver cancer, 203 patients with liver cirrhosis, and 248 patients with chronic hepatitis admitted to our hospital from January to December, 2013, as well as 210 healthy individuals, were included in the study.Serum levels of GP73, AFP- L3, AFP, and AFU were determined.Comparison of non- normally distributed data was made by Kruskal- Wallis H test, and multiple comparisons were made by Mann- Whitney U test.Comparison of rates was made by chi- square test.P < 0.05 was considered significantly different.Receiver operating characteristic (ROC) curves were drawn with healthy individuals and patients with chronic hepatitis or liver cirrhosis as controls, and Logistic fitting and ROC analysis were used to evaluate the diagnostic values of these markers.Results The GP73 level of liver cirrhosis group (177.0 (116.0, 247.0) ng /ml) was significantly higher than those of liver cancer group (141.0 (83.3, 218.8) ng /ml) and chronic hepatitis group (151.0 (83.0, 235.3) ng /ml) (U = 22 116.5 and 21 052.0, P<0.05 for both) .The AFP- L3 and AFP levels of liver cancer group (11.3 (4.3, 21.2) % and 78.4 (7.1, 2455.8) ng /ml) were significantly higher than those of liver cirrhosis group (6.0 (4.0, 8.0) % and 10.0 (3.8, 49.5) ng /ml) and chronic hepatitis group (7.0 (5.0, 9.0) % and 18.8 (4.4, 79.6) ng /ml) (U = 16009.0 /16083.5 and 22456.5 /22346.5, P < 0.05 for all) .According to the ROC curves drawn using healthy individuals as a control, the areas under the ROC curve (AUCs) for GP73, AFP- L3, AFP, and AFU were 0.827, 0.817, 0.901, and 0.680, respectively;GP73, AFP- L3, and AFP had a higher diagnostic accuracy for liver cancer than AFU.According to the ROC curves drawn using non- liver cancer patients as a control, the AUCs for the four markers were 0.573, 0.734, 0.753, and 0.552, respectively;AFP- L3 and AFP had some diagnostic accuracy for liver cancer, and their cut- off values were 8.55% (56.6%, 84.9%) and 49.88 ng /ml (57.7%, 80.9%) , respectively, when the sensitivity and specificity reached the peak values.Conclusion Increased GP73 is related to hepatic impairment and chronic fibrosis, and it has a better sensitivity for the diagnosis of liver diseases.AFP- L3 and AFP have good specificity for the diagnosis of liver cancer, and a combination of the two markers can increase the diagnostic sensitivity for liver cancer to 62.1%.
