Abstract:
Objective To explore the application value of Golgi protein-73 (GP73)and AFP in single and combining form in the diagnosis of primary hepatocelluar carcinoma (PHC).Methods Eighty PHC,65 liver cirrhosis,54 chronic hepatitis patients and 50 controls were selected in the First Afiliated Hospital in Xinjiang Medical University from May to September in 2011,GP73 was detected by ELISA and AFP was measured by clinical chemiluminescence.The sensitivity and specificity of each parameter in single and combining form were evaluated.Results Serum GP73 in PHC group 282.0(163.6-366.7) μg/L,liver cirrhosis group 211.8(107.5-295.7) μg/L,chronic hepatitis group 100.3(61.8-191.3) μg/L and control group 58.3(43.4-83.6) μg/L was tested by Kruskal-Wallis(H =106.6,P ＜0.01).GP73 in PHC group was further compared with liver cirrhosis group,chronic hepatitis group and control group using MannWhitney test,significance was found,(U was 1796.0,826.5,154.0,respectively,all P ＜0.01).In the single form,the sensitivity of GP73 [82.5％ (66/80)] was higher than AFP [66.3％ (53/80),x2 =4.65,P ＜0.05],but the specificity of GP73 [63.3％ (107/169)] was lower than AFP [88.7％ (150/169),x2 =28.91,P ＜0.05].There were 27 AFP negative cases in PHC group,but 22 of them were GP73 positive,making the positive rate of GP73 [81.5％ (22/27)] in PHC patients with AFP negative.There were 14 GP73 negative cases of in PHC group,but 9 of them were AFP positive,making the positive rate of AFP [64.3％ (9/14)] in PHC patients with GP73 negative.In series diagnostic test,the specificity of combining form [95.9％ (162/169)] was higher than AFP [88.7 ％ (150/169),x2 =6.00,P ＜ 0.05] ; in parallel diagnostic test,the sensitivity of combining form [93.8％ (75/80)] was higher than GP73 [82.5％(66/80),x2 =4.84,P ＜0.05].In PHC group,52 patients with HBV infection,10 patients with HCV infection and 18 patients without virus infection,GP73 was 309.5 (170.5-370.5) μg/L,351.0 (274.7-397.9) μg/L and 210.1 (156.8-306.7) μg/L,respectively,no significance was found (H =4.0,P ＞0.05).Conclusion GP73 and AFP have a complementary feature of sensitivity and specificity in the early diagnosis of PHC,some PHC cases with AFP negative can be avoided missing efficiently by parallel diagnostic test.
