摘要
目的探讨食管癌三野淋巴结清扫术术后肿瘤复发特点及其相关因素。方法回顾性分析2002年1月-2007年12月接受食管癌三野淋巴结清扫术治疗的184例胸中段食管鳞癌患者的临床资料,Logistic回归分析判定术后3年内肿瘤复发的危险因素。结果 3年内86例(46.7%)患者肿瘤复发,平均复发时间为11.4个月,其中局部-区域性复发46例(25.0%)、血行转移40例(21.7%)。单因素分析显示,食管癌术后复发与浸润深度、淋巴结转移、血管浸润、淋巴管浸润、淋巴结远处转移显著相关(P<0.05)。Logistic分析显示,影响食管癌患者术后局部复发的因素为淋巴结转移、淋巴管浸润;影响术后血行转移复发的独立因素为血管浸润。结论食管癌的局部复发与淋巴结转移有关,而血行转移与血管浸润有关;食管癌三野淋巴结清扫术后可以降低局部复发率。
Objective To investigate the recurrence patterns after extended radical esophagectomywith three-field dissection for the esophagus carcinoma and to analyze its relative risk factors.Methods Clinical data of 184 patients between Janunary 2002 and December 2007 who underwent extended radical esophagectomy with three-field dissection were studies,The risk factors of postoperative recurrence within 3 years were analyzed with Logistic regressive model.Results Recurrence was recognized in 86 patients（46.7%）.The median disease-free interval until recurrence was 11.4 months.46 patients（25.0%） developed a locoregional recurrence,and 40（21.7%） developed a hematogenous recurrence.Recurrences was correlated with depth of invasion,lymph node metastasis,venous invasion,lymphatic invasion and distant lymph node metastasis.Logistic regressive analysis revealed that locoregional recurrence was correlated with lymph node metastasis and lymphatic invasion.For the distant recurrence,vascular invasion was found the most important prognostic factor.Conclusions Locoregional recurrence was related to lymph node metastasis,whereas distant recurrence was due to vascular invasion.Extended radical esophagectomy with three-field dissection may reduces locoregional recurrence.
