ABSTRACT
Objective To investigate the expression level of serum Golgi protein-73 (GP73) in patients with primary hepatocellular carcinoma (HCC), or accompanied with Budd-Chiari syndrome (BCS), and to discuss its clinical value in making early diagnosis. Methods The peripheral serum samples were collected in 490 individuals, including patients with HCC (n = 65), cholangiocarcinoma (CC, n = 35), Budd-Chiari syndrome accompanied with HCC (n = 40), type B virus hepatitis (n = 60), cirrhosis after B hepatitis (n = 60), Budd-Chiari syndrome complicated by cirrhosis (n = 60), other malignant lesions (n =50), benign hepatic lesions (n = 60) and healthy volunteers (n = 60). The expression levels of serum GP73 and AFP were determined by using Elisa and electrochemiluminescence methods separately. Results The expression level of serum GP73 in the patients with HCC , CC or BCS plus HCC were significantly higher than that in the other individuals (P 0.05). The area under ROC, sensitivity, specificity and the accuracy of GP73 for the diagnosis of CC were 0.774 , 88.6%, 72.7% and 73.9%respectively, and the optimal cut-off value was 45.40 ng/ml. Conclusion In diagnosing HCC, the expression level of serum GP73 is superior to AFP. It is hopeful that serum GP73 may be proved to be an early serum tumor marker for HCC.
ABSTRACT
Objective To explore the content change of Alpha Fetal Protein(AFP) and Alpha Fetal Protein Variants(AFP-L3) pre-and post-liver transplantation operation for liver cancer patients.Methods AFP-L3 was de-termined by micro centrifugal column from twelve cases of successive sera(For each case,one original shale pre-oper-ation,and mole shares post-operation successively),and preserved from patients who were diagnosed as fiver cancer and completed fiver transplantation operation.simultaneously the content of AFP and AFP-L3 in the original serum were also determined.and the ratio of AFP-L3 in AFP was calculated in order to compare the content change of AFP and the ratio of AFP-L3 pre-and post-liver transplantation operation.Results Compared with twelve cases of pre-and post-operation,the AFP in only five cases turned tO negative;The AFP in other cases keeped positive though AFP-L3%tumde to negative.and the content of AFP in some specific cases still keeped in a high level.Regarding AFP-L3,besides two casses turning to negative immediately after operation,the content of AFP-L3 in other patients de-creased gradually after operation,and it approached to negative(AFP-L3%<10%).Through statistical analysis,be-tween the half lives of AFP and AFP-L3%,there waa no statistic significance.Therefore,AFP-L3% could be considered as an independent reference item.Conclusion After a radical cure of liver resection or liver transplantation operation,AFP-L3%usually turned to negative in a rather short period (about 1 to 20 days).The ratio of AFP-L3 in AFP became be-low 10%,and it indicated that the operation would be quite complete,remaining liver would have hepatitis or hepatocirrho-sis.Otherwise,the ratio was not decrease during a long period,and it indicated the operation had not eliminated focuses completdy.
