目的 探讨胸段食管癌淋巴结转移的规律及临床意义。方法 对 2 2 2例胸段食管癌术后的临床资料进行回顾性分析。结果 2 2 2例中 86例 (38.7% )淋巴结转移。清扫淋巴结 1342枚 ,转移度 15 .7% (2 11/1342 ) ,其中胸上、中、下段癌转移度分别为 35 .2 %、12 .3 %、2 0 .2 % ,胸上段食管癌转移以颈部、食管旁、支气管旁为主 ;中段癌以瘤旁、胃左动脉旁、食管旁、贲门旁及隆突下转移为主 ;下段以瘤旁、贲门旁、隆突下及胃左动脉旁转移为主。不同浸润深度的转移度有差异 (P <0 .0 1) ,不同分化程度的转移度无差异 (P >0 .0 5 )。结论 胸段食管癌病灶部位越靠上转移度越高 ,但胸下段比胸中段转移度高 ,转移率与肿瘤浸润深度有关。
Objective To investigate the regularity and clinical significance of lymph node metastasis in thoracic esophageal cancer. Methods The clinical data of 212 cases of thoracic esophagectomy were retrospectively analyzed. Results Twenty-two (38.7%) of the 222 patients had lymph node metastases. The number of lymph nodes was 1342, and the degree of metastasis was 15.7% (2/11/1342). The metastatic degree of the upper, middle and lower segments were 35.2%, 12.3% and 20.2% respectively. The upper thoracic esophageal cancer The metastasis was mainly by the neck, beside the esophagus and the bronchus. In the middle segment, the tumors were mainly located beside the tumor, the artery beside the left gastric artery, beside the esophagus, beside the cardia and under the carina. Artery next to the main transfer. There was a difference in the degree of metastasis between different depths of invasion (P <0.01). There was no difference in the degree of metastasis between different degrees of differentiation (P> 0.05). Conclusion The upper thoracic esophageal carcinoma has a higher degree of metastasis, but the lower thoracic segment has a higher degree of metastasis than the middle thoracic segment. The metastasis rate is related to the depth of tumor invasion.
