目的了解２０年来该院住院儿童恶性肿瘤概况。方法对 １９７９至 １９９８年１６７ ０１８例住院儿童进行了回顾性分析。结果小儿恶性肿瘤２１０７例，占住院儿童的１．２６％，男女之比１．７：１。白血病１１８０例占第一位（５６．００％）．其余依次为肾母细胞瘤１８７例（８．８８％），恶性淋巴瘤１４９例（７．０７％），神经母细胞瘤１２９例（６．１２％）．脑肿瘤１２７例（６．０３％）等。发病年龄以学龄儿童多见，但某些肿瘤有其相对集中的发病年龄。住院儿童恶性肿瘤病死率９０年代与８０年代相比明显降低．其发病的绝对人数明显上升。结论诊断技术的进步和各种治疗手段的改进使小儿恶性肿瘤死亡率下降，小儿恶性肿瘤尤其是白血病人数上升。
