The relationship between DNA ploidy or differentiation of nucleus and steroid hormone receptor contents was studied in 50 cases of primary breast cancer. The result indicated that estrogen receptor (ER) negative or weakly positive breast cancer had bigger nucleus, poorer differentiation and higher DNA content than ER positive cancer. Determination of DNA content by cell image showed the same result as by flow cytometry. Both DNA con- tent and steroid hormone receptor assay are proposed as additional tools for...

The relationship between DNA ploidy or differentiation of nucleus and steroid hormone receptor contents was studied in 50 cases of primary breast cancer. The result indicated that estrogen receptor (ER) negative or weakly positive breast cancer had bigger nucleus, poorer differentiation and higher DNA content than ER positive cancer. Determination of DNA content by cell image showed the same result as by flow cytometry. Both DNA con- tent and steroid hormone receptor assay are proposed as additional tools for determining the biological characteristics of the cancer cell and provide more objective indicator for adjuvant systemic treatment of

应用细胞图像分析仪、流式细胞分析仪检测50例乳腺癌标本,同时测定其雌激素受体水平和癌细胞的分化程度,从中发现随着癌细胞分化程度越差,癌细胞雌激素受体水平越低,癌细胞核的面积却增大,异倍体肿瘤的细胞核面积明显大于二倍体肿瘤的细胞核,且S期细胞比率增高。作者认为系统地对乳腺癌标本进行图像分析,流式细胞分析仪检测及癌组织的分级和受体状态的测定,对判断乳腺癌的生物学形态和遗传特性提供了更为客观的依据,为指导临床辅助治疗提供了客观的指标。

The DNA contents in cells from 15 histopathologically normal endometria and 28 endometrial carcinoma was measured by flow cytometry (FCM). In the normal cases, only single DNA peak was found, all in the diploid region and the range of DNA index values (0.93-1.07) was used for defining the limits of DNA for diploid tumor cases. Aneuploid cell population was found in 36% of malignant endometria and in the remained cases, the FCM finding showed no differences as compared with those of benign tissue. Ploidy aberations...

The DNA contents in cells from 15 histopathologically normal endometria and 28 endometrial carcinoma was measured by flow cytometry (FCM). In the normal cases, only single DNA peak was found, all in the diploid region and the range of DNA index values (0.93-1.07) was used for defining the limits of DNA for diploid tumor cases. Aneuploid cell population was found in 36% of malignant endometria and in the remained cases, the FCM finding showed no differences as compared with those of benign tissue. Ploidy aberations were correlated to histologic tumor grades. Aneuploidy was more common (100%) in poorly differentiated tumors than in the highly or moderately differentiated (15.4%) (P<0.05). Receptor status was significantly correlated with ploidy as diploid tnmors were more aften receptor positive (P<0.05), but it was not correlated to FIGO stage, depth of myometriali invasion and spread to vessel. In normal endometria, the fraction of cells with DNA content corresponding to s-phase(s-fraction) was 14% in average. In well and moderately differentiated diploid tumors the s-fraction was about the same (13.7% vs 16%), but in the poorly differentiated it was significantly higher (37%):

采用流式细胞分析术(FCM)检测15例正常子宫内膜组织与28例子宫内膜癌组织的DNA含量与细胞周期分布,并由此推算出DNA指数(DI)和S期细胞比率(SPF),结合雌、孕激素受体检测结果,从分子生物学角度对子宫内膜癌的生物学特性进行了研究。15例正常子宫内膜组织均为二倍体,其DI为0.93~1.07,而28例子宫内膜癌中二倍体有18例(64%),异倍体出现率与组织分化程度及受体状况密切相关(P均<0.05),SPF亦与分化程度相关。

作者采用流式细胞仪对38例卵巢交界瘤,20例卵巢恶性肿瘤及4例正常卵巢进行DNA含量测定。结果:①交界瘤非整倍体率为16%,恶性肿瘤非整倍体率为100%;②非整倍体交界瘤与恶性肿瘤之间DI值、PI值、S期细胞比率无差异(P>0.05);③DI<1.21是判断交界瘤的客观指标,符合率87.93%;④DI值是唯一影响预后的因素。
