The expected survival time was shorter in patients with higher expresson of MMP 2 and MMP 9 . Therefore, MMP 2 and MMP 9 are considered as important factors in invasive metastasis and prognosis of hRCC.

• 预后调查分析显示 ；MMP2 和MMP9阳性表达者术后 5年存活率均明显低于阴性表达者 (P <0 0 5 )。 研究表明 ；MMP2 和MMP9在肾癌组织中可以高度表达 ；并与肾癌的侵袭和转移有关 ；其检测对临床判断肾癌预后有指导意义。
