The lymphatic drainage from the stomach is anatomically elaborate and it is very hard to predict the pattern of lymph node (LN) metastases from gastric cancer (GC). However, there are LN stations metastases that are more frequently observed depending on the tumor location. Furthermore, the incidence of metastasis to various regional LN stations depends on the depth of gastric-wall invasion. The Japanese Gastric Cancer Association (JGCA) classifies the regional LNs draining the stomach into 33 regional lymphatic stations. These are distinguished into three (N1-N3) groups with respect to the location of the primary tumor. The aim of this classification is to provide a common language for the clinical, surgical, and pathological description of GC.
胃的淋巴引流在解剖学上很复杂，很难预测胃癌（GC）的淋巴结（LN）转移模式。然而，根据肿瘤位置，某些淋巴结站转移更为常见。此外，不同区域淋巴结站的转移发生率取决于胃壁浸润深度。日本胃癌协会（JGCA）将引流胃的区域淋巴结分为33个区域淋巴结站。根据原发肿瘤的位置，这些淋巴结站分为三组（N1-N3）。该分类的目的是为GC的临床、手术和病理描述提供一种通用语言。
