自本世纪初就寻找正常细胞与癌细胞间生化差别,结果在生化及细胞组成上未见明显差异。正常细胞癌变时其生化改变极微小,有些是发生在细胞膜上,在细胞膜上出现一种新的物质(抗原)。在机体免疫功能生理中,已判明存在免疫监视机构,即有新抗原的变异细胞一出现,机体在其增殖之前就加以损害。临床上,癌的发生考虑是由于机体免疫监视机构减弱或恶性细胞增殖的速度超过机体所能控制的程度。癌细胞表面出现的新抗原称为肿瘤特异性移植抗原(Tumor-specific transplatation anti- Since the beginning of this century to find the biochemical differences between normal cells and cancer cells, the results in the biochemical and cellular composition no significant differences. When normal cells become cancerous, their biochemical changes are minimal, some occur on the cell membrane, and a new substance (antigen) appears on the cell membrane. In the immune physiology of the body, it has been determined that there is an immune surveillance agency, ie, mutant cells with new antigens appear as soon as they occur and the body damages before its proliferation. Clinically, the occurrence of cancer is considered due to the body immune surveillance institutions or malignant cells proliferation rate of proliferation faster than the body can control. The new antigen present on the surface of cancer cells is called Tumor-specific transplatation anti-
