恶性肿瘤特异性生长因子 (ＴＳＧＦ)是一种由恶性肿瘤细胞产生的特异性物质 ,是恶性肿瘤细胞及周边毛细血管大量扩增的物质基础 ,在恶性肿瘤形成的早期即释放到血液中并达到一定浓度。而与非恶性肿瘤细胞及血管增生无明显关系。因此 ,选择适宜的检测方法对ＴＳＧＦ浓度进行检测 The tumor-specific growth factor (TSGF) is a specific substance produced by malignant cells, which is the material basis for the massive expansion of malignant tumor cells and peripheral capillaries. It is released into the blood early in the formation of malignant tumors and reaches A certain concentration. There was no significant relationship with non-malignant tumor cells and vascular proliferation. Therefore, select the appropriate detection method to detect the concentration of TSGF
