目的探讨Ki-67抗原与子宫颈鳞癌新辅助化疗(NACT)和放射治疗(RT)的敏感相关性。方法在新辅助化疗前后用免疫组化检测32例宫颈鳞癌组织Ki-67的表达。结果化疗前患者Ki-67的表达水平在不同年龄段组(<45岁和≥45岁)、不同临床期别组(Ⅰb～Ⅱa和Ⅱb～Ⅲb)和不同病理分级组(高中分化和低分化)之间相互比较差异有统计学意义(P=0.008、0.009、0.000)。化疗后患者Ki-67表达水平与化疗前比较明显下降,差异有统计学意义(P=0.000)。化疗前Ki-67表达程度不同,化疗和化放疗的疗效明显不同,化疗疗效高表达组与低表达组比较差异有统计学意义(P=0.033);化放疗疗效高表达组与低表达组比较差异无统计学意义(P=0.375);高表达组、低表达组对化疗和化放疗的疗效比较差异均有统计学意义(P=0.001、0.000)。结论子宫颈鳞癌治疗前Ki-67表达强度与化疗敏感性呈正相关;虽然存在Ki-67阳性表达强度愈强、NACT+RT的完全缓解率愈高的趋势,但未显示明显的放射敏感相关性;治疗前检测Ki-67表达可以为预测化疗和放疗敏感性提供客观依据,但Ki-67能否确定为预测子宫颈鳞癌新辅助化疗和放疗敏感性的可靠指标还需增加样本作进一步研究。

目的探讨非小细胞肺癌中ASPP1和ASPP2蛋白表达与细胞凋亡和增殖的关系及其临床意义。方法采用免疫组化Evision法,检测肺癌组织芯片中90例肺癌和25例相应癌旁组织ASPP1、ASPP2及Ki-67的表达;用TUNEL法检测细胞凋亡,以增殖指数和凋亡指数计数表示增殖与其凋亡。结果肺癌组织中ASPP1的表达显著低于癌旁正常肺组织(χ2=5.188,P0.05);在肺癌组织中细胞凋亡指数(AI)和增殖指数(MI)呈正相关(r=0.622,P0.05)。结论肺癌组织中ASPP1低表达及由此诱导的细胞凋亡与增殖失衡可能在肺癌发生、发展中起重要作用。
