摘要: Multiple genetic alterations were investigated in colorectal cancer, including changes DNA content, mutations ras oncogenes, and deletions involving chromosomes 5, 17, 18. A non-random association of mitotic abnormalities by site was seen, with both types occurring significantly more frequently distal tumours. In contrast, the frequency c-Ki-ras did not differ between proximal cancers. addition, associated each other change content. The data provide strong support for hypothesis that colon carcinoma might mechanisms their initiation and/or progression.
