Abstract: Lymph node metastasis is one of the important factors influencing the prognosis of gastric cancer patients. Accurate and reasonable lymph node staging is greatly significant in evaluating the course of the disease, in estimating the prognosis, and in making a reasonable treatment plan. Local and international research institutions recently found that new staging methods for lymph nodes associated with the prognosis of gastric cancer (e.g., metastastic lymph nodes ratio, log odds of positive lymph nodes, negative lymph node count, and lymph node micrometastasis) can also predict the prognosis of gastric cancer patients. In this paper, the development history, current status of lymph node staging of gastric cancer, and research progress on the new staging methods for lymph nodes as-sociated with the prognosis of gastric cancer are reviewed.
