淋巴结转移是影响残胃癌预后的重要因素,残胃癌治愈性切除的累积5年存活率可达50%以上。残胃癌的淋巴结转移率,N0:76%,N1:18%,N2:18%,N3:6%。残胃癌的淋巴结转移部位除胃周的第1站外,脾门、脾动脉干淋巴结,肠系膜根部淋巴结、腹主动脉周围淋巴结和下纵隔淋巴结均有高频度的转移率。熟知残胃的淋巴流向和淋巴结转移规律,积极、合理的淋巴结清扫,有助于改善残胃癌的预后。
Lymph node metastasis is an important factor that affects the prognosis of gastric residual stump cancer. The cumulative 5-year survival rate of curative resection of gastric stump cancer can reach more than 50%. Stomach cancer lymph node metastasis rate, N0: 76%, N1: 18%, N2: 18%, N3: 6%. Stomach cancer lymph node metastasis in addition to the first station of the stomach, the spleen door, splenic artery lymph nodes, mesenteric lymph nodes, abdominal aortic lymph nodes and mediastinal lymph nodes have high-frequency transfer rate. Familiar with gastric remnant lymph flow and lymph node metastasis, positive and reasonable lymph node dissection, contribute to improve the prognosis of gastric cancer.
