The clinicopathologic features between NLM group and SLM group.

*.The T staging by CT was acquired after experienced image doctor read the pictures;
**.The LN status by CT was considered when the short-axis diameter was larger than 6 mm for perigastric lymph nodes and larger than 8 mm for the extraperigastric lymph nodes, especially nodes with arounded shape and enhancement on contrast-enhanced CT.
The clinicopathologic features between NLM group and SLM group.

1. CT所评估的T分期，均由经验丰富的影像医师阅片后确定；
2. CT判定淋巴结（Lymph Node，LN）状态的标准为：胃周淋巴结短轴直径大于6 mm，胃外淋巴结短轴直径大于8 mm；对于呈类圆形且增强CT扫描可见强化的淋巴结，尤需纳入考量。
3. 对比非淋巴结转移组（NLM）与淋巴结转移组（SLM）的临床病理特征。
