摘要
应用流式细胞仪对40例贲门癌切缘残留癌的DNA含量(DI)和倍体类型进行定量测定。结果发现,浸润较深、分化程度较低的残癌,其DI和异倍体率显著高于浸润较浅,分化程度较高的残癌(P<0.05);残癌的组织学类型与其DNA含量和倍体类型无关。提示,残癌的病理学诊断应强调其浸润深度和分化程度。文中对残癌与其主体癌之间的关系亦进行了探讨。
DNA content and ploidy patterns were measured by flow cytometry in 40 cases of residual tumors at the resected margins of the stomach and esophagus for gastrocardiac adenocarcinoma. The results showed that flow cytometric DNA content and ploidy patterns were related to the depth of infiltration and degree of differentiation in the residual tumors, but not to the histological types. This indicated that emphasis should be put on the invasive depth and differential degree of residual tumors in pathological diagnosis. The relationship between the main tumors and residual tumors was also discussed.
