为探讨胸段食管癌淋巴结清扫的必要性，回顾分析１０６例胸段食管癌标本及淋巴结清扫标本和临床资料，作淋巴结转移癌与癌长度、深度及临床分期的相关分析。结果食管癌长度、深度与淋巴结转移明显相关，上胸段食管癌同样需要清扫胃左血管旁和贲门旁淋巴结。提示，胸段食管癌需作胸腹甚至颈区淋巴结清扫。
In order to investigate the necessity of lymph node dissection in thoracic esophageal cancer, 106 cases of thoracic esophageal cancer specimens and lymph node dissection specimens and clinical data were retrospectively analyzed. Correlations between lymph node metastases and the length, depth, and clinical staging of cancer were analyzed. Results The length and depth of esophageal cancer were significantly associated with lymph node metastasis. Upper esophageal cancer of the upper thoracic region also required the removal of the left gastric perivascular and para-parapharyngeal lymph nodes. Tips, thoracic esophageal cancer need for chest and abdomen or cervical lymph node dissection.
