胃癌浸润血管易引起血源性转移 ,这里需要肿瘤血管的大量增加 ,新形成的毛细血管的基底膜如呈碎片状 ,则更易使肿瘤细胞逸出 ,肿瘤的生长和转移更需要肿瘤细胞产生的血管生成因子。作者回顾性分析胃癌血管浸润与其临床结局的关系 ,并测定原发肿瘤中血管内皮生长因子 (VEGF)和 p Invasive blood vessels in gastric cancer can cause blood-borne metastases. This requires a large increase in tumor blood vessels. The newly formed basement membrane of capillaries, such as fragments, is more likely to allow tumor cells to escape. The growth and metastasis of tumors require tumor cells to produce Angiogenic factors. The authors retrospectively analyzed the relationship between vascular infiltrates in gastric cancer and their clinical outcomes, and measured vascular endothelial growth factor (VEGF) and p in primary tumors.
