本文对94例儿童肾母细胞瘤进行病理分析,着重探讨肿瘤组织发生学及组织学分类。根据肿瘤组织结构提出新的分类法,即上皮型、胚芽型、间叶型及混合型;又按细胞的分化程度分为八个亚型。随访47例中,按照 Colins 危险期计算,存活14例,存活率为30%。高分化型预后较好,低分化型预后较差。本分类法有利于对肿瘤组织的全面观察分析和推测预后。
In this paper, 94 cases of children with Wilms tumor pathological analysis, focusing on tumor histology and histological classification. According to the structure of the tumor, a new taxonomy was proposed, that is, epithelial type, germ type, mesenchymal type and mixed type, and divided into eight subtypes according to the degree of cell differentiation. Follow-up 47 cases, according to Colins dangerous period, the survival of 14 cases, the survival rate was 30%. Well-differentiated type of prognosis is better, poorly differentiated type of poor prognosis. This classification is conducive to the comprehensive observation of tumor tissue and speculation prognosis.
