1986年9月至1990年6月,按日本“食管癌规约”中食管分段,淋巴结分组、分站对175例胸段 Eca行切除合并淋巴结清除术.全组淋巴结转移(LNM)率 57.7%,颈、胸、腹分别为10.9%、40.6%、32.6%.LNM程度与肿瘤长度、浸润深度呈正相关.胸上段 Eca主要转移到上纵隔和下颈部;胸中段可有颈胸腹LNM;胸下段腹部较胸部LNM率为高.Eca合理根治术应行食管大部切除,颈部食管吻合,颈胸腹三领域淋巴结清除术.Eca病变部位不同其LN清除范围应有所侧重.
From September 1986 to June 1990, according to the Japanese esophageal cancer statute, esophageal segmentation, lymph node grouping, sub-stations, 175 cases of thoracic Eca resection with lymph node dissection. The total lymph node metastasis (LNM) rate was 57.7% The cervical, thoracic, and abdominal levels were 10.9%, 40.6%, and 32.6%, respectively. The degree of LNM was positively associated with tumor length and depth of invasion. The upper thoracic Eca mainly metastasized to the upper mediastinum and lower neck; the mid thoracic segment had cervical thoracic and abdominal LNM; The LMH rate was higher in the chest and abdomen than in the chest. The esophagectomy, cervical esophageal anastomosis, and neck thoracoabdominal lymph node dissection should be performed for the Eca’s radical resection. The LN clearance range of the Eca lesions should be different.
