原发性食管小细胞癌 (PESC)是一种较少见的食管高度恶性肿瘤 ,其恶性程度高 ,侵袭性强 ,淋巴及血行转移早 ,患者预后极差。随着病理诊断技术水平的提高 ,其发病率有上升趋势。我科 1 990～ 1 998年共收治 PESC1 6例 ,占同期食管癌的 1 .4% (1 6/1 1 40 )。现分析报告如下。1
Primary esophageal small cell carcinoma (PESC) is a rare type of highly malignant esophageal cancer with a high degree of malignancy, strong invasion, early lymphoid and hematogenous metastasis, and very poor prognosis.
