中文摘要：

胃癌腹膜转移涉及黏附、降解、移动、血管生成等阶段，每一阶段均有多种基因的改变和各种生物学活性物质的参与。随着分子生物学的发展，参与转移的基因越来越多地作为早期诊断的肿瘤标记物或是分子治疗的靶点而被应用于基础实验和临床研究。

英文摘要：

Many procedures like adhesion, degradation, migration, angiogenesis, etc. are involved in peritoneal metastasis of gastric cancer, there are plenty of genes modified and biology active compounds participated in. With the progress of molecular biology, the metastasis related genes are learned gradually, most of them become the tumor marker of the early diagnosis or the target of molecular therapy, which are applied in the basic experiments and clinical researches.
