The content change of AFP and AFP-L3 pre-and post-liver transplantation operation for liver cancer patients / 中国基层医药

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.
