恶性肿瘤特异性生长因子(tum or spec ific grow th factor,TSGF),是恶性肿瘤形成和生长时释放到外周血液中的一种特异性肿瘤标志物,对恶性肿瘤的血管增生起重要作用,而与非肿瘤血管增生无明显关系,目前已经明确肿瘤的生长和转移具有血管依赖性。恶性肿瘤形成的早期,就有肿瘤细 Tumor specific growth factor (TSGF) is a specific tumor marker released into the peripheral blood during the formation and growth of malignant tumors and plays an important role in the angiogenesis of malignant tumors. There is no significant relationship with non-tumor angiogenesis, and it is now clear that tumor growth and metastasis have vascular dependence. In the early stage of malignant tumors, there are tumors
