食管癌切除术后局部复发及远处转移是食管癌治疗后影响五年生存率的两个主要原因。食管癌的切除范围和有无癌残留是造成局部复发和远处转移的直接原因。国外一些人认为食管癌的根治切除范围,应包括离肿瘤上下端各10cm,围绕食管的整个后纵隔组织要完整切除,其切除之组织两侧为胸膜面,前侧为心包,后侧为食管系膜包括奇静脉、胸导管、主动脉分枝和所在区的淋巴结及纤维脂肪组织。对于颈部食管癌还须行颈
Local recurrence and distant metastasis after resection of esophageal cancer are two main reasons that affect the five-year survival rate after esophageal cancer treatment. The extent of resection of esophageal cancer and the presence or absence of cancer are the direct causes of local recurrence and distant metastasis. Some foreign people think that the scope of radical resection of esophageal cancer should include 10 cm from the upper and lower ends of the tumor.
