即使在早期,食管癌常伴有淋巴结转移,在治疗时需行广泛淋巴结清扫,作者观察无明显组织学转移病例中的淋巴结微转移的发生率、类型及其临床意义。取日本Niigata大学医学院第一外科于1985～1994年所收治的194例浸润性胸段食管癌进行分析,均已根治性切除和胸、纵隔、腹淋巴结清扫, Even in the early stage, esophageal cancer is often accompanied by lymph node metastasis, and extensive lymph node dissection is required during the treatment. The authors observed the incidence, type and clinical significance of lymph node micrometastasis in cases with no obvious histological metastasis. 194 cases of infiltrating thoracic esophageal cancer were collected from the first surgical department of Niigata University School of Medicine in Japan from 1985 to 1994 and had radical resection and chest, mediastinum and abdominal lymph node dissection,
