目的探讨腹段食管癌及贲门癌淋巴结转移特征的异同点。方法收集36例腹段食管癌及28例贲门癌患者术前CT资料,观察记录淋巴结大小、优势分布情况,并进行统计学分析,了解有无差异。结果以淋巴结短径≥10 mm为转移标准,腹段食管癌CT淋巴结检出率为73.5%(144/196),贲门癌CT淋巴结检出率为83.7%(170/203)。腹段食管癌胸腔淋巴结转移率:7区11.1%(4/36)、8区27.8%(10/36)、9区8.3%(3/36),腹腔转移以No.7组36.1%(13/36)、No.1组19.4%(7/36)及No.2组11.1%(4/36)为主。贲门癌淋巴结转移以第1站的No.1组17.9%(5/28)、No.2组28.6%(8/28)、No.3组39.3%(11/28)、No.4组25.0%(7/28)及第2站的No.7组35.7%(10/28)为主。结论 CT以短径≥10 mm为淋巴结转移判断标准具有可行性,但存在一定假阳性率。腹段食管癌胸腔淋巴结转移以7、8、9区为主,腹腔转移以No.7组及No.1、No.2组为主。贲门癌淋巴结转移以第1站的No.1～No.4组及第2站的No.7组为主。
Objective To investigate the similarities and differences of lymphatic metastasis in esophageal and cardia carcinoma of the abdominal segment. Methods Preoperative CT data of 36 cases of abdominal esophageal cancer and 28 cases of cardia cancer were collected. The size and distribution of lymph nodes were observed and statistically analyzed to find out whether there was any difference. Results The detection rate of CT lymph node was 73.5% (144/196) in esophageal cancer and 83.7% (170/203) in gastric cardia. The rates of thoracic lymph node metastasis of abdominal esophageal cancer were 11.1% (4/36) in 7 zones, 27.8% (10/36) in 8 zones, 8.3% (3/36) in 9 zones, and 36.1% /36), 19.4% (7/36) in No.1 group and 11.1% (4/36) in No.2 group. Cardiac cancer lymph node metastasis in the first station of the first group of 17.9% (5/28) in the first group, No.2 group 28.6% (8/28), No.3 group 39.3% (11/28), No.4 group 25.0 % (7/28) and No.7 group 2 (35.7% (10/28)). Conclusion It is feasible to judge the criteria of lymph node metastasis with short diameter ≥ 10 mm, but there is a certain false positive rate. Belly esophageal cancer thoracic lymph node metastasis to the 7,8,9 zone-based, abdominal metastasis to No. 7 and No. 1, No. 2 group based. Cardiac cancer lymph node metastasis in the first station No. 1 to No. 4 group and the second station No. 7 group based.
