原发性食管小细胞癌较少见。我院１９９０～１９９６年共诊治２１例，占同期食管癌的１．３４％。其中漏误诊５例，占２３．８％。由于食管小细胞癌在生物学特性，治疗原则等方面与食管鳞癌有很大差别，故如何避免漏误诊有重要意义。现将本组５例分析报告如下。１临床资料... Primary esophageal small cell carcinoma is less common. In our hospital from 1990 to 1996, 21 cases were diagnosed and treated, which accounted for 1.34% of esophageal cancer in the same period.

Since esophageal small cell carcinoma is very different from esophageal squamous cell cancer in terms of biological characteristics, treatment principles, etc., how to avoid misdiagnosis is important. The analysis report of 5 cases in this group is as follows. 1 clinical data...
