儿童期肿瘤以胚胎细胞肿瘤的报告较多,其中恶性实质肿瘤约占儿童期癌瘤的百分之六十。肾胚瘤(Wilm′s瘤),神经母细胞瘤(Neuroblastoma)是最常见的,几乎为小儿独有的实质性癌瘤。两者可见于任何年龄,但以三岁左右最多见,好发于男性,左右侧无明显差异,少数可双侧出现瘤体。肾胚胎、神经母细胞瘤预后不良,根据肾胚瘤N.W.T S分类观察其ⅠⅡⅢⅥⅤ期患儿的存活率分别为80％、52％,36％,30％及
Childhood cancer to embryonal cell tumors are more reported, of which about 70% of malignant tumors of childhood cancer. Neoplastic (Wilm’s tumor) and Neuroblastoma are the most common and almost exclusively pediatric carcinomas in children. Both can be seen at any age, but most commonly seen around the age of three, occurs in men, no significant difference between the left and right side, a few can appear on both sides of the tumor. Kidney embryo and neuroblastoma have poor prognosis. According to the N.W.T S classification of neoplastic embryos, the survival rate of children with stage ⅠⅢⅢV is 80%, 52%, 36%, 30% and
