All cases of tumours and tumour-like conditions in children 0-14 years reported to the Swedish cancer registry during the period 1958-74 have been studied. The material consists of 3797 individuals on file in this registry. The most common cancer diagnoses in children 0-14 years are leukemia and tumours of the central nervous system (together constituting approximately 58% of all cases). Almost half of the cancers affect children below five years of age. The lowest incidence occurs in the ages 7-8 years, and the highest occurs during the first year of life. The types of tumours below one year of age show a different distribution than in any other age groups. A significant increase in the incidence of childhood cancer occurred, while the mortality rates showed a slight decrease during the period studied. A remarkable increase in the incidence figures was noted concerning tumours of the nervous system, especially in boys. The decrease in the mortality rates was most obvious regarding Wilms' tumour, and leukemia in children 0-4 years of age.
对1958年至1974年期间向瑞典癌症登记处报告的所有0至14岁儿童的肿瘤及肿瘤样病症病例进行了研究。该资料包括该登记处存档的3797名个体。0至14岁儿童中最常见的癌症诊断是白血病和中枢神经系统肿瘤（两者合计约占所有病例的58%）。几乎一半的癌症发生在5岁以下儿童。发病率最低的年龄段是7至8岁，最高的是在出生后的第一年。1岁以下儿童的肿瘤类型分布与其他任何年龄组都不同。在所研究的期间，儿童癌症发病率显著上升，而死亡率略有下降。神经系统肿瘤的发病率数字显著增加，尤其是在男孩中。死亡率下降在肾母细胞瘤以及0至4岁儿童的白血病方面最为明显。
