采用免疫组化方法对Ｃ－ｅｒｂＢ－２癌基因进行标定，通过Ｋｉ－６７抗体的表达揭示癌细胞增殖状况。综合分析二者的表达状态与癌瘤大小等的关系，认为Ｃ－ｅｒｂＢ－２癌基因与癌瘤大小无显著关系，该基因决定着癌瘤的发生；Ｋｉ－６７与癌瘤大小有一定关系，它决定着癌细胞的增殖速度。二者均为过度表达，则意味病人预后不良。 The C-erbB-2 oncogene was calibrated by immunohistochemistry and the proliferation of cancer cells was revealed by the expression of Ki-67 antibody. Comprehensive analysis of the relationship between the expression status of the two and the size of the cancer, etc., that C-erbB-2 oncogene has no significant relationship with the size of the tumor, the gene determines the occurrence of cancer; Ki-67 has a certain relationship with the size of the tumor It determines the rate of proliferation of cancer cells. Both are over-expressed, which means poor prognosis.
