临床上膀胱肿瘤的性质存在很大差异,高度分化之肿瘤通常为整倍体,低度分化肿瘤则伴非整倍体。当肿瘤由分化较好向分化稍差发展,处于不典型的形态学变化时,根据目前组织病理学分级方法,尚难以作出确切的判断,将涉及病人的治疗与预后。为进一步建立鉴定肿瘤性质的客观分级方法,本文作者应用流动细胞荧光分析法(Flowcytofluorometric method),对膀胱肿瘤活体组织进行细胞倍体与增殖的测定,并与膀胱冲洗脱落细胞、组织病理学与细胞学的改变进 Clinically, there are great differences in the nature of bladder tumors. Highly differentiated tumors are usually euploid, and low-grade tumors are associated with aneuploidy. When the tumor develops from poorly differentiated to poorly differentiated, and is in atypical morphological changes, it is difficult to make an accurate judgment based on the current histopathological grading method, which will involve the patient’s treatment and prognosis. In order to further establish an objective grading method to identify the nature of tumors, the authors used a flow cytofluorometric method to measure the ploidy and proliferation of bladder tumor biopsies, and to rinse the exfoliated cells, histopathology and cells of the bladder.
