自２０世纪７０年代Folkman首先提出肿瘤的生长和转移依赖于肿瘤组织内新生的血管以来，研究者对于血管形成与肿瘤的增殖、转移的关系极为重视，然而过多的强调血管系统在肿瘤中的作用，肿瘤淋巴管形成（Lymphangiogenesis）被掩盖犤１犦。肿瘤组织内是否存在淋巴管形成；淋巴 Since Folkman first proposed in the 1970s that the growth and metastasis of tumors depend on new blood vessels in tumor tissues, researchers have attached great importance to the relationship between blood vessel formation and the proliferation and metastasis of tumors, but excessive emphasis has been placed on the vascular system in tumors. The role of lymphangiogenesis (Lymphangiogenesis) was obscured. Whether there is lymphatic vessel formation in the tumor tissue;
