胰腺癌浸润及转移分子机制研究进展

浸润及转移是恶性肿瘤重要的生物学特征,是导致胰腺癌患者死亡的主要原因.目前研究发现,胰腺癌浸润及转移与一系列分子生物学改变密切相关,包括肿瘤转移相关基因异常、细胞外基质降解、肿瘤诱导血管生成、细胞黏附力及细胞因子改变等,但其确切机制仍不明确,仍需进一步深入研究.

Progresses on the molecular mechanisms of invasion and metastasis of pancreatic neoplasms

Invasion and metastasis are the important biological features of malignant neoplasms,and are the main reasons for the death of patients with pancreatic neoplasms.Current researches find that invasion and metastasis of pancreatic neoplasms are closely related to series of molecular biological changes,including' abnormalities of tumor metastasis-related genes,degradation of extracellular matrix,tumor-induced angiogenesis,changes of the adhesion molecules and cytokines.However,the definite mechanism still remains unclear,and further researches are needed.
