探讨食管癌肉瘤的临床病理特征。方法 通过 5例食管癌肉瘤术前X线钡餐造影术、纤维内窥镜观察 ,并术后病理检查、免疫组织化学染色、随访。结果 5例食管癌肉瘤术前仅 1例确诊 ,4例诊断为鳞癌。肿瘤为带蒂的息肉型 ,癌的浸润限于粘膜层。癌与肉瘤成分相间混杂但无移行过渡 ,免疫组化染色各自表达相应抗体。术后随访 :5年以上 3例 ,2～ 5年 2例 ,患者健在。结论 食管癌肉瘤术前X线钡餐造影和胃镜难以确诊。其组织学上有别于肉瘤样癌。本病术后 5年生存率高于 5 0 %。
To investigate the clinicopathological features of esophageal sarcoma. Methods 5 cases of esophageal sarcoma preoperative X-ray barium meal imaging, fiber endoscopy, and postoperative pathological examination, immunohistochemical staining, follow-up. Results In 5 cases of esophageal sarcoma, only 1 case was diagnosed preoperatively and 4 cases were diagnosed as squamous cell carcinoma. The tumor is pedunculated polyp type, cancer infiltration limited to the mucosa. The components of cancer and sarcoma were mixed but no transitional transition, immunohistochemical expression of the corresponding antibodies. Postoperative follow-up: more than 5 years in 3 cases, 2 to 5 years in 2 cases, patients were alive. Conclusion The preoperative radiographs of X-ray barium meal and gastroscopy are difficult to diagnose. Its histology is different from sarcomatoid carcinoma. The 5-year survival rate of this disease is higher than 50%.
