大肠腺瘤是最常见的人体结肠的息肉样病变,许多证据说明大肠腺瘤是腺癌的先兆,因此,分析大肠腺瘤的染色体可进一步了解这两种疾病间的关系。作者在芝加哥大学医院直接制备38例人良性大肠腺瘤的染色体,用荧光显带技术进行研究。材料来自结肠镜检所取的标本和/ Colorectal adenomas are the most common polypoid lesions of the human colon. Many evidences indicate that colorectal adenomas are precursors of adenocarcinoma. Therefore, analysis of colorectal adenoma chromosomes can further understand the relationship between these two diseases. The authors directly prepared chromosomes of 38 human benign colorectal adenomas at the University of Chicago Hospital and studied them with fluorescent banding technique. The material comes from the specimen taken from the colonoscopy and/
