摘要
作者采用癌灶多点取材法,对食管癌患考癌细胞DNA含量进行了分析。结果表明,患者癌细胞DNA异倍体和多异倍体检出率和随机一点取材法相比,分别增加了50%和3.5倍。用该取材法还可以检测患者的DNA倍体异质性和DNA干系的分布情况。
DNA content were measured on tumor cells of cancer nest in patients with esophageal carcinoma sampling bymulti-site. The result showed that the rate of aneuploid cells and multi-aneuploid cells were raised 0.5 times and 3.5 times.Meanvvhile this method can be used to measure the heterogeneity of DNA content and distribution of DNA stimline in patientswith esophaeal carcinoma.
