多发性原发性恶性肿瘤(以下简称MPMT)是指同一宿主的单个或多个器官组织同时或先后发生两个或两个以上的原发性恶性肿瘤而言。MPMT的诊断标准多数人接受Warren及Gates的标准。CT扫描对中枢神经系统MPMT的诊断有一定价值。MPMT有同时性异时性两种,MPMT多沿用Strave—Christensen分类法。其发病机制“多中心性”学说已受普遍重视,文章强调活检的重要性以及提高临床医师对MPMT的认识、避免由于误诊而使病人失去诊治机会。
Multiple primary malignancies (hereinafter referred to as MPMT) refer to single or multiple organ tissues of the same host occurring simultaneously or sequentially with two or more primary malignancies. The diagnostic criteria for MPMT Most accept Warren and Gates standards. CT scan for the diagnosis of central nervous system MPMT has some value. MPMT has simultaneous heterochronous two, MPMT followed Strave-Christensen classification. The pathogenesis of “polycentrism” has received universal attention. The article emphasizes the importance of biopsy and enhances clinicians’ understanding of MPMT so as to prevent patients from losing their chance of diagnosis and treatment due to misdiagnosis.
