【摘要】 我们应用流式细胞术对３５例大肠癌术后标本进行了ＤＮＡ含量分析。结果表明，异倍体肿瘤占６２．９％（２２／３５），二倍体肿瘤占３７．１％（１３／３５），与以往文献报道相符；二倍体肿瘤的ＤＮＡ含量明显低于异倍体肿瘤；二倍体肿瘤的Ｇ０／Ｇ１期细胞数明显高于异倍体肿瘤，而Ｓ、Ｇ２Ｍ期细胞数则明显低于异倍体肿瘤。这说明，ＤＮＡ的倍体水平可作为大肠癌诊断及判断预后的一项辅助指标。更多还原

【Abstract】 The DNA contents in 35 paraffin-embedded samples of colonic cancer were analyzed using flow cytometry.The rate of DNA non-diploid tumor was 62.9%(22/35) and was unanimous to the pre-reports.The DNA contents in DN A diploid tumors were tess than that of DNA nondiploid tumors.The cell numbers in Go/Giphases of DNA diploid tumors were significantly greater than that of DNA non-diploid tumors,while the cell num-bers in S,G2M phases of the fermer were less than that of the later(P<0.05).These findings sugguest that DNA ploidy be considered as an objective parameter of colonic cancer for diagnosis and the measuring of cell scatter in every phases has certain value for clinical features.更多还原
