食管多原发癌国内外资料报告较少。我院自1975年1月至1985年5月经纤维食管镜(下称纤食镜)诊断食管瘤734例,其中经病理诊断或手术证实的食管多原发癌16例,占同期食管癌总数的2.18％。现通过纤食镜下形态学的观察,探讨食管多原发癌的病因、诊断及其防治。 There are fewer reports of domestic and foreign data on multiple primary esophageal cancers. In our hospital, from January 1975 to May 1985, 734 cases of esophageal cancer were diagnosed by fiberoptic esophagoscopes. Among them, 16 cases of multi-primary esophageal cancer were confirmed by pathological diagnosis or surgery, accounting for the total number of esophageal cancers in the same period. 2.18%. The morphological observation under the glass fiberoptic microscope is used to investigate the etiology, diagnosis, and prevention and treatment of multiple primary esophageal cancers.
