摘要
目的:探讨Ki-67抗原在膀胱移行细胞癌(BTCC)中的定量表达及其与BTCC生物学行为的关系。方法:用流式细胞技术(FCM)对36例BTCC和10例正常膀胱黏膜细胞组织标本进行Ki-67检测。结果:Ki-67在BTCC组织中的阳性表达率为(10.89±7.88)%,在正常膀胱黏膜组织中的阳性表达率仅为(0.27±0.07)%,两者比较差异有统计学意义(P<0.01);临床分期Tis^T1为(4.93±2.95)%,T2~T4为(18.34±5.24)%,病理分级Ⅰ级为(3.17±0.83)%,Ⅱ级为(10.97±2.35)%,Ⅲ级为(21.60±3.70)%,随着分期分级的增加,Ki-67的表达率也逐步增加,差异有统计学意义(P<0.01)。结论:定量检测Ki-67能准确评估BTCC的生物学行为,Ki-67是膀胱癌的重要肿瘤标记物。
Objective:To investigate the quantitative expression of Ki-67 antigen in transitional cell carcinoma of bladder and to evaluate the relationship between Ki-67 and the biological behavior of transitional cell carcinoma of bladder (BTCC). Methods:Samples of tumor and normal mucosa were taken from 36 patients and 10 cases of normal bladder tissue respectively. The percentage of Ki-67 positive cells in these samples were examined by flowcytometry. Results: Percentage of Ki-67 positive cells was ( 10.89±7.88)% in tumor tissue and (0.27±0.07) % in normal tissue( P 〈0.01). The positive cells were noted in( (4.93±2.95)% of Tis~T1 and (18.34 ± 5.24)% of T2~T4,and(3. 17±0. 83)% of G1 ,(10. 97±2. 35)% of G2,and (21.60±3.70)% of G3 tumor tissue. With the progression of clinical stage and grade, the positive rate of Ki-67 expression increased ( P 〈0.01 ). Conclusions: Quantitative examination of Ki-67 expression can accurately evaluate the biological behavior of BTCC. Ki-67 is a useful tumor markers.
