摘要
目的探讨胸段食管鳞状细胞癌的淋巴结转移特点。方法对170例胸段食管鳞状细胞癌临床病理资料进行回顾性分析。结果全组淋巴结转移率为46.5%(79/170),大于4枚淋巴结转移率为17.6%(30/170)。淋巴结转移率与肿瘤部位、病理分期、分化程度有关(P<0.05)。T3、T4期食管癌膈下淋巴结转移率高,分别为15.2%、29.6%。结论胸段食管鳞状细胞癌淋巴结转移率与位置、病理分期、分化程度有关,对单纯行放疗的中晚期胸下段食管鳞状细胞癌,建议照射膈下淋巴结引流区。
Objective To study the characteristics of lymph node metastases of squamous cell carcinoma of thoracic esophagus. Methods To analyse retrospectively the clinical and pathological data of 170 cases of squamous cell carcinoma of thoracic csophagus. Results Lymph node metastases was found in 79 of 170 treated patients （46.5 % ）, 30 patients were found with more than 4 involved lymph nodes（ 17.6 % ）. Tumor site ,tumor grade and cells differentiation were factors influencing lymph node metastases of squamous cell carcinoma of thoracic esophagus. （P 〈0.05）. Inferior phrenic lymph nodcs metastascs was higher in Esophageal carcinoma of stage Ⅲ and stage Ⅳ（P 〈 0.05）, about 15.2 % and 29.6 %. Conclusion The lymphatic involvement is associated with location of tumor, tumor grade and cells differentiation. An additional inferior phrenic lymph nodes irradiation is required for the patients who develop advanced squamous cell carcinoma locate in low thoracic segments of oesophagus, while receive radiotherapy only.
