摘要
研究细胞周期蛋白 (cyclinD1 )、细胞增殖核抗原 (PCNA)在胸腺瘤中表达及意义。方法 :用免疫组织化学方法 (S P)法 ,检测 1 8例良性胸腺瘤、2 0例侵袭性胸腺瘤和 1 6例胸腺癌标本cyclinD1、PCNA。结果 :在 3组胸腺肿瘤中cyclinD1阳性表达分别为 5 1 8( 2 7 78% )、1 3 2 0 ( 6 5 0 0 % )、1 4 1 6 ( 87 5 0 % ) (P <0 0 5 ) ;PCNAⅢ—Ⅳ指数分别为 :5 1 8( 2 7 78% )、1 5 2 0 ( 75 0 0 % )、1 3 1 6 ( 81 2 5 % ) (P <0 0 5 )。cyclinD1、PCNA阳性表达与胸腺瘤的类型、临床分期、淋巴结转移、生存率等参数有关。结论 :cyclinD1、PCNA参与胸腺瘤细胞的增殖并影响其分化 。
Purpose:To study the expression of cyclin D1 and PCNA in thymomas and its significance. Methods:Immunohistochemical method was used to examine the sections from 18 thymomas, 20 invasive thymomas and 16 thymic carcinomas. Results:The positive ratios of cyclin D1 were 5/18 (27.78 %),13/20(65 00 %),14/16(87 50 %)(P<0 05);The positive ratios of PCNA were 5/18(27.78%),15/20(75 00%),13/16(81 25%)(P<0 05) in the three thymoma groups, respectievly. The positive ratios of cyclin D1 and PCNA protein were related to the histopathology, clinical stage and prognosis. Conclusions:cyclin D1 and PCNA protein are involved in the proliferation and influence differentiation of thymoma, which can be used as an useful index for prognosis monitoring.
