对浅表性食管癌(限于粘膜上皮、粘膜肌层、粘膜下层)的外科治疗存在很大分歧。作者对其大体形状与癌肿侵入深度及区域淋巴结转移的关系进行研究,以设计出对浅表性食管癌的治疗策略。 材料与方法:作者对206例原发性食管癌患者行手术治疗,其中33例为浅表性食管癌。所有病例均行区域淋巴结切除,对每一淋巴结都作病理学检查。按内镜下肿瘤形状特点将癌肿分为两类:(1)隆起型,有突起;(2)平坦型或凹陷型,无突起。 结果:肿瘤浸润越深,其淋巴结受累的可能性越大。所有隆起型均达粘膜肌层以下。隆
There is a great deal of divergence in the surgical treatment of superficial esophageal cancer (limited to mucosal epithelium, mucosal muscularis, submucosa). The authors studied the relationship between the general shape, invasion depth of cancer, and regional lymph node metastasis to design therapeutic strategies for superficial esophageal cancer. Materials and Methods: The authors performed surgical treatment on 206 patients with primary esophageal cancer, 33 of which were superficial esophageal cancers. Regional lymph node resection was performed in all cases, and pathological examination was performed for each lymph node. According to the endoscopic features of the shape of the tumor, the cancer was divided into two categories: (1) bulging type with protrusions; (2) flat or depressed type with no protrusions. Results: The deeper the tumor invasion, the greater the possibility of lymph node involvement. All bulge types reach below the mucosal muscle. Long
