摘要: 目的与方法:为探Wilms 瘤中p16 基因表达与肿瘤病理分型和临床分期之间的关系,应用免疫组织化学SP 方法,对52 例Wilms 瘤及7 例肿瘤周围正常肾组织(对照) 手术标本中p16 基因的表达情况进行检测。结果:52 例wilms 瘤中有16 例p16基因表达阳性,阳性率为30. 8 % ,其中预后良好型p16 基因表达阳性率为37. 2 %(16/ 43) ,预后差者为0 %(0/ 9) ,均明显低于正常对照100 %(7/ 7) ,差异具有显著的统计学意义( P < 0. 05) 。在Ⅰ、Ⅱ、Ⅲ、Ⅳ临床期中, p16 表达阳性率以Ⅰ期最高,逐步递减,分别为47. 6 %(10/ 21) 、37. 5 %(3/ 8) 、28. 6 % (2/ 7) 、6. 3 %(1/ 16) 。结论:Wilms 瘤中p16 基因表达与肿瘤病理分型和临床分期存在联系, p16 基因失活似是Wilms 瘤发生发展中的晚期事件。

Abstract: Purpose and Methods : In order to investigate the p16 gene expression and it s relationship with pathological type and clinical stage , 52 Wilms tumor specimens and 7 normal renal tissues aroud tumor were stained routinely by SP immunohistochemical method. Results : Positive expression rate of p16 gene was 30. 8 % 16/ 52) in tumor specimens and significantly lower than that in cont rol 100 % (7/ 7) ( P < 0. 05) . The positiverates were 37. 2 % (16/ 43) , 0 % (0/ 9) in the favorable pathological type and the unfavorable pathological type ,and 47. 6 % (10/ 21) , 37. 5 % (3/ 8) , 28. 6 % (2/ 7) ,6. 3 % (1/ 16) in Ⅰ, Ⅱ, Ⅲ, Ⅳclinical stage respectively. Conclusion : The positive expression of p16 gene was correlated with pathological type and clinical stage , and p16 inactivation seems to be the later event of Wilms tumor progression.
