The International Agency for Research on Cancer (IARC) is sponsoring a worldwide study of childhood cancer incidence. Cancers in children are highly specific and differ in many ways from cancers found in adults. Data for the international study will be presented according to the classification scheme described below which has been devised specifically for use with paediatric cancers. The features of this scheme are: (1) it is based on the International Classification of Diseases for Oncology (ICD-O); (2) diagnostic groups are defined mainly in terms of morphology; (3) the common types of childhood cancer are individually specified; (4) certain other rare conditions of interest are distinguished; (5) it provides for flexibility of data presentation with respect to amount of detail; (6) all possible combinations of ICD-O morphology and topography codes are included; and (7) the maximum number of codes has been allocated to specific categories. There is a great need for standardization in the classification of childhood cancers and we propose that the scheme be used for presentation of incidence data for results of aetiological and other related studies of cancer in children.
国际癌症研究机构（IARC）正在赞助一项关于儿童癌症发病率的全球研究。儿童癌症具有高度特异性，在许多方面与成人癌症不同。国际研究的数据将根据以下所述的分类方案呈现，该方案是专门为儿科癌症设计的。该方案的特点是：（1）它基于国际肿瘤疾病分类（ICD - O）；（2）诊断组主要根据形态学定义；（3）单独列出了儿童癌症的常见类型；（4）区分了某些其他感兴趣的罕见病症；（5）在数据呈现的详细程度方面提供了灵活性；（6）包括了ICD - O形态学和部位编码的所有可能组合；（7）已将最大数量的编码分配给特定类别。儿童癌症分类非常需要标准化，我们建议该方案用于呈现儿童癌症病因及其他相关研究结果的发病率数据。
