恶性肿瘤是威胁人类生命健康的主要疾病,其发病隐匿,死亡率高,但目前尚无彻底根治的有效方法。浸润和转移是恶性肿瘤的显著特征,瘤细胞脱落从原发灶侵入周围组织并向远处转移是临床抗肿瘤治疗失败和患者死亡的主要原因,因此对于恶性肿瘤侵袭和转移的研究成为目前肿瘤研究的关键所在,本文就肿瘤转移机制及相关细胞分子作一论述。 Malignancy is a major disease that threatens the health of human beings. Its incidence is insidious and its mortality rate is high. However, there is no effective way to completely cure it. Invasion and metastasis are the prominent features of malignant tumors. The invasion of tumor cells from the primary tumor into the surrounding tissues and the distant metastasis of tumor cells are the main reasons for the failure of clinical anti-tumor therapy and the death of patients. Therefore, the study on the invasion and metastasis of malignant tumors has become the current tumor The crux of the research, this article on the mechanism of tumor metastasis and related cell molecules to make a discussion.
