Gastric cancer (GC) remains one of the most important malignant diseases with significant geographical, ethnic, and socioeconomic differences in distribution. Sentinel lymph node (SLN) mapping is an accepted way to assess lymphatic spread in several solid tumors; however, the complexity of gastric lymphatic drainage may discourage use of this procedure, and the estimated accuracy rate is, in general, reasonably good. This study aimed at reviewing the current status of SLN mapping and navigation surgery in GC. SLN mapping should be limited to tumors clinically T1 and less than 4 cm in diameter. Combination SLN mapping with radioactive colloid and blue dye is used as the standard. Despite its notable limitations, SLN mapping and SLN navigation surgery present a novelty individualizing the extent of lymphadenectomy.
胃癌（GC）仍然是最重要的恶性疾病之一，在地理、种族和社会经济分布上存在显著差异。前哨淋巴结（SLN） mapping是评估几种实体瘤淋巴扩散的一种公认方法；然而，胃淋巴引流的复杂性可能会阻碍该方法的应用，而且总体估计准确率还算不错。本研究旨在回顾GC中SLN mapping和导航手术的现状。SLN mapping应仅限于临床T1期且直径小于4 cm的肿瘤。放射性胶体和蓝色染料联合SLN mapping被用作标准方法。尽管存在明显局限性，但SLN mapping和SLN导航手术为淋巴结清扫范围的个体化提供了一种新方法。
