简介:客观:复制错误(RER)与colorectal癌(CRC)的开始和开发有关。调查RER+和RER的不同生物行为?CRC。方法:染色PCR单个的海滨符合构造多型性(PCR-SSCP)和使中毒的polyacrylamide胶化电气泳动方法的银被用来在染色体2上在4loci检测microsatellite不稳定性(MSI),5,17在60colorectal癌(CRC)和他们的配对的正常组织的嵌入石蜡的标本。如果,RER+被获得2或更多的loci作为获得额外的乐队表现了。结果:结果证明RER+在19/60CRC,7个案例在之中有家庭历史被发现。根据阿姆斯特丹的标准,4作为世袭nonpolyposiscolorectal癌症(HNPCC)被诊断,并且哪个3个案例是RER+。在HNPCC(75%)的比率RER+在分散的CRC(28.5%)之中比那显著地高。大多数RER+CRC有糟糕区分的腺癌的特征(P<0.01),包含冒号的右边的趋势(P<0.05),有家庭历史的一个更高的比例(P<0.05),Ducke的A和B阶段(P<0.05)。结论:结果显示RER+是在CRC的一个相对普通的分子的事件。在RER+和RER之间有不同clinico病理学的特征和行为吗?CPC。
