【摘要】 报告43例肾肿瘤和61例膀胱肿瘤石蜡包埋组织流式细胞术（FCM）检测结果:脱氧核糖核酸指数、S期细胞比例和细胞增殖指数在膀胱肿瘤和肾肿瘤间以及不同组织来源肾肿瘤间（肾细胞性、移行细胞性、胚胎性和结缔组织性）差别无显著性,而与病人预后关系密切;在膀胱肿瘤和肾肿瘤分级和分期的基础上,FCM检测可提供更多有关预后信息。更多还原

【Abstract】 Ploidy and cell-cycle stage were determined by flow cytometry (FCM) in 43 paraffin embeded specimens tumours of the kidney and 61 paraffin embeded specimens tumours of the bladder. There were no significant differences in the deoxyribonucleic acid index (DI) ,the percentage of S-phase cells and proliferative index (PI) between the tumours of the kidney and the bladder , and among the tumours of the kidney originating in parenchymatous, transitional , embryonic and connective tissues .regardless of tissular origin ( P >0. 1). The results of FCM was statistically and significantly associated with clinical outcome ( P <0. 05),providing additional information in tumours originating in urinary apparatus for prognosis beyond that obtained from tumour grade and stage.更多还原
