摘要胃癌根治术后，尤其无淋巴结转移的早期胃癌根治术后仍有一定复发率，这促使研究者采用更敏感的方法追踪可能存在而被漏诊的转移，尤其是淋巴结微转移。随着检测技术的进步，微转移检出率明显提高。但其对胃癌分期、预后等诸多方面的影响仍有较大争议，因此，尚无共识的临床处理策略。而随着内镜技术治疗早期胃癌的兴起，如何平衡患者术后生命质量和治疗安全的关系，避免漏诊存在微转移的淋巴结，使得微转移研究更加迫切。

abstractsThere is still a certain recurrence rate after extensive lymphadenectomy even to patients with node-negative gastric cancer.It promotes the researchers to use a more sensitive and effective way to track tumor cells which are missed,especially lymph node micrometastases.With the development of detection tech-nology,the diagnostic rate of micrometastasis is significantly increased.There are so many controversies about the impact of lymph node micrometastases that no consensus on the clinical treatment can be reached.In recent years,with the rise of endoscopic therapy,how to balance the relationship between the quality of life and the safety makes the research of micrometastases more urgent.
