摘要 目的探讨P16INK4A及P57蛋白表达对CIN1病人病程预测的可行性。方法将组织学确定为CIN1病人的剩余TCT标本进行P16INK4A及P57KIP2蛋白免疫细胞化学染色,同时,对病人进行1~1.5年的随访,观察其表达与病人病程转化的关系。结果67例病人P16INK4A阴性表达者21例,2O例治愈(95.2%),1例未愈(4.8%),未见1例恶化;p16INK4A阳性表达共46例,22例治愈(47.8%),16例未愈(34.8%),8例恶化(17.4%),其中表达(++)及(+++)者恶化比例最高,达30.4%;两者比较有显著性差异(X2=25.777,P〈0.001),提示P16INK4A阳性表达的病例预后较差,对p16INK4A阳性表达者可作LEEP术或活检后进一步评估诊断的正确性以进一步治疗。而P16INK4A(-)者无1例病变进展,提示相对无危险的妇女就可能不须实行过度治疗或频繁随访。P57KIP2阳性表达者59例,40例CIN病变治愈(67.8%);14例未愈(23.7%),5例恶化(8.5%);而p57KIP2表达阴性者2例治愈(25%);3例未愈(37.5%);3例病变进展(37.5%),两者比较有显著性差异(X2=20.980,P=-0.002)。提示P57H阻阳性表达的病例预后较好,可能不须实行过度治疗或频繁随访。结论将P16INK4A和P57KIP2进行联合检测对判断宫颈CIN1的生物学行为可能具有更重要的意义。
