ABSTRACT
Objective:To study the dynamic changes of serum AFP before and after cryosurgery for liver cancer.Methods:The dynamic changes of serum AFP in 46 cases of liver cancer before and after cryosurgery were analyzed.Results:In those with a negative AFP before operation,the value of AFP increased rapidly 3 days after operation,kept positive for half a month,and was difficult to be turned negative.In those with a positive AFP before operation,there were no evident changes 3 days after operation,and the value of AFP decreased to normal half a month after operation.Conclusion:The change of AFP had some characteristic in the cryosurgery of liver cancer.Detection on the changes of AFP value is helpful in judging the curative effect and prognosis of cryosurgery for liver cancer patients.
