近年来,国内外文献关于多发性原发癌的报告日渐增加,尤其国外文献不仅二种、三种原发癌,最近陆续报道一个病人可患六种原发癌。1973年在意大利举行国际多原发癌的会议上,报告研究多原发癌的目的,不仅有助于临床诊断与治疗,而且对癌瘤的发生学与免疫学也有重要意义。今将本院遇到五例扼要介绍如下,并复习文献,加以讨论。 In recent years, reports on multiple primary cancers have gradually increased in domestic and foreign literatures. In particular, there are not only two or three primary cancers in foreign literature, but it has recently been reported that one patient can suffer from six primary cancers. At the International Conference on Multiple Primary Cancers held in Italy in 1973, the purpose of reporting the study of multiple primary cancers was not only helpful for clinical diagnosis and treatment, but also important for the development and immunology of cancer. Here are five examples of this hospital’s brief introduction as follows, and review the literature and discuss it.
