肿瘤血行转移是指肿瘤从原发病灶脱落并随血液循环转移到远处靶器官,并逐渐形成转移灶的过程。血小板活化包括血小板形态的改变、血小板聚集功能及血小板成分的释放。研究发现随着肿瘤的转移,血小板活化的数目或血小板活化的可能性就会随之增加,两者呈正相关关系。反之减少血小板活化的数目或抑制血小板活化可不同程度抑制肿瘤转移。 Tumor metastasis refers to the tumor from the primary lesion off and with the blood circulation to the distant target organs, and gradually formed the process of metastasis. Platelet activation includes changes in platelet morphology, platelet aggregation and platelet release. The study found that as the tumor metastases, the number of platelet activation or the possibility of platelet activation will increase, the two are positively correlated. Conversely reducing the number of platelet activation or inhibiting platelet activation may inhibit tumor metastasis to varying degrees.
