In presence of non- cancer suspicious patients, serum MMP-2 activity in chronic hepatitis is contrary to decrease at lowest among them. The level of MMP-9 similarly low compare with normal control. Therefore found out that the process from chronic hepatitis to hepatoma, a variation of MMP-2 is earlier to decrease and then to rise. Although there is no great variation but lower in MMP-9 compare to normal control.

肝癌病人的血清中MMP-9及MMP-2两者的变化与正常人相比差距最易观察，当比较所有非癌症病人血清时，慢性肝炎病人血清MMP-2活性表现相反的下降，而且是其中最低的，因此可以看出由慢性肝炎到肝癌的过程MMP-2的变化是先下降再升高，MMP-9虽然没有大变化，相较於正常人却都偏低。
