胸段食管癌肿瘤侵及深度与淋巴结转移度的关系

Study on the relationship of depth of tumor invasion and lymph node metastasis of thoracic esophageal carcinoma

目的探讨胸段食管癌肿瘤侵及深度(T分期)与淋巴结转移度之间的关系。方法对89例胸段食管癌临床资料进行回顾性分析。结果全组总的淋巴结转移率为70.7%,淋巴结转移度为46.9%。肿瘤长度之间淋巴结转移度无显著性差异(P>0.05),肿瘤侵及深度之间淋巴结转移度有显著性差异(P<0.01)。结论胸段食管癌淋巴结转移度与肿瘤侵及深度相关,与肿瘤长度无关。

Objective To analyze the the relationship of depth of tumor invasion and lymph node metastasis of thoracic esophageal carcinoma. Methods The clinical materials of 89 patients underwent radical resection on the carcinoma of thoracic esophagus were retrospectively analyzed. Results Lmph node metastases were found in 89 of the 63 patients （70.7%） . In 1026 lymph nodes desected, metastases were identified in 482 lymph nodes （46. 9% ）. The different depth of tumor invasion was a factor influencing lymph node metastases （ P 〈 0.01 ）, but the different length of tumor was not a factor influencing lymph node metastases（ P 〉 0.05）. Conclusion Lymph node metastasis relates to depth of tumor invasion but not to the length of tumor .
