摘要 目的 :探讨结直肠癌P1 6 及P -gp表达对生物学行为及预后的影响。方法 :应用S -P免疫组化法检测 5 2例结直肠癌中P 16、P -gp的表达。结果 :P1 6 、P -gp阳性率分别为 6 1 5 % (32 5 2 )、82 6 % (4 3 5 2 )。P1 6 表达水平与癌组织分化呈正相关(P <0 0 5 ) ,与肿瘤细胞的浸润深度及淋巴结转移呈负相关 (P <0 0 5 )。P -gp表达水平与癌组织的分化无关 (P >0 0 5 ) ,与肿瘤细胞的浸润深度及淋巴结转移呈正相关 (P <0 0 5 )。P1 6 与P -gp阳性表达呈明显负相关 (P <0 0 5 )、P1 6 阳性率越高 ,P -gp表达越低。结论 :P1 6 、P -gp蛋白表达能反映结直肠癌的生物学特性 ,同时检测两者的表达情况可作为肿瘤预后判断。
