目的 比较食管癌术前放射治疗后的原发灶癌组织及转移性淋巴结的反应。方法 筛选出 30例已有淋巴结转移的食管癌病理切片 ,观察它们的原发病灶、转移淋巴结及未转移淋巴结放射治疗后的形态学变化和差别。结果 30例切除的食管癌标本 ,原发肿瘤放射治疗反应Ⅰ度 14例 ,Ⅱ度 12例 ,Ⅲ度 4例 ;转移的淋巴结放射治疗反应Ⅰ度 19例 ,Ⅱ度 9例 ,Ⅲ度 2例。结论 淋巴结转移癌放射治疗后形态学改变似略小于原发灶癌组织。
Objective To compare the response of esophageal cancer patients with primary cancerous tissue and metastatic lymph node after radiotherapy. Methods Thirty cases of esophageal carcinoma with lymph node metastasis were screened and their morphological changes and differences were observed after primary radiotherapy, metastatic lymph node metastasis and non-metastatic lymph node metastasis. Results In 30 cases of esophageal cancer resected, the primary tumor response was 14 ° in grade Ⅰ, 12 cases in grade Ⅱ and 4 cases in grade Ⅲ. There were 19 cases in grade Ⅰ, 9 cases in grade Ⅱ and 2 cases in grade Ⅲ . Conclusion The morphological changes of lymph node metastatic carcinoma after radiotherapy are slightly less than that of primary cancerous tissue.
