本文评述肿瘤转移的最新观点并根据动物实验研究及临床经验讨论廿碳酸类(eicosan-oids)与肿瘤转移的关系。一,肿瘤转移的步骤通常认为由原发肿瘤生长到转移需经以下步骤:肿瘤在原发部位生长到一定阶段,瘤细胞脱落并进入循环(淋巴管与血管),在其中停留直至到达远处的靶器官,随后侵入血管内皮并移至外皮部,
This article reviews recent insights into tumor metastasis and discusses the relationship between eicosan-oids and tumor metastasis based on animal experimental studies and clinical experience. First, the steps of tumor metastasis are usually considered to be from the growth of primary tumor to metastasis through the following steps: the tumor grows to a certain stage at the primary site, tumor cells fall off and enter the circulation (lymphatic vessels and blood vessels), stay in it until reaching a distance The target organ, which then invades the vascular endothelium and moves to the outer skin.
