The sites of lymph node metastasis in mediastinum after radical surgery for middle thoracic esophagus cancer

目的 探讨食管癌根治术后纵隔淋巴结转移的特点。方法 回顾性分析 92例胸中段食管癌根治术后纵隔淋巴结肿大的CT资料 ,对发生于每个区的淋巴结肿大的病例数进行统计。结果 75例纵隔淋巴结转移发生在食管癌根治术后 1年内 ;右上气管旁淋巴结转移 46例 ,隆突下淋巴结转移 31例 ,左下及右下气管旁淋巴结转移 2 7例。结论 纵隔淋巴结转移是胸中段食管癌根治术后最常见的转移部位 ,建议做常规CT扫描 ,而右上气管旁 (2R区 )

Objective To study the sites of lymph node metastasis in mediastinum after radical surgery for esophagus cancer. Methods From 1989 to 1998, 92 patients with mid thoracic esophageal cancer received radical surgery. The sites of lymph node metastasis in mediastinum were analyzed. Results Seventy five(85%) of 92 patients developed lymph node metastasis in the mediastinum within 1 year after operation. The sites of lymph node metastasis were located in R 2 region in 46 patients, in regions 7 and 8 in 31, and in region 4L and 4R in 27.Conclusions The lymph node metastasis in the right para bronchus area is common in those patients with mid thoracic esophageal cancer after surgery. We suggest that chest CT scan be a routine examination for these patients because the routine roentgenogram and physical examination can not show them.
