DNA倍体分析在结直肠肿瘤研究中的新进展

Advances in the Research of DNA Ploid in Colorectal Neoplasms

人体正常的体细胞有恒定的DNA 2倍体含量,细胞癌变过程中伴随DNA含量的改变,DNA非整倍体细胞是恶性肿瘤的特异性标志.此外,DNA指数对肿瘤的早期诊断、鉴别诊断、判断预后及评价疗效有重要意义.

The content of DNA deploid exit in normal somatic cell eternally which will alter when the neoplasms occurs. The cell DNA aneuploid is the characteristic symbol. DNA indexes have an important significance in early diagnosis to the neoplasms, differential diagnosis, estimate prognosis and appraise curative effect.
