作者总结了1981年4月～1990年5月间18例患颅底或颈椎脊索瘤的儿童。年龄4～18岁,中位13岁;男性7例,女性11例;肿瘤位于颅底者15例,位于颈椎者3例;组织类型为非软骨样脊索瘤者16例,软骨样脊索瘤2例。所有病人均先行手术,但手术均不能彻底切除肿瘤,术后肿瘤体积从13.9～282cm~3,中位80cm~3。病人均未出现远处转移。术后放疗采用高能X线与160MeV质子线的混合线束 The authors summarized 18 children with skull base or cervical chordomas from April 1981 to May 1990. Aged 4 to 18 years, with a median age of 13 years; 7 males and 11 females; 15 tumors located in the skull base and 3 patients located in the cervical spine; 16 were non-chondral chordomas, 16 were cartilage-like chordomas example. All patients were surgically treated, but the surgery can not completely remove the tumor, the tumor volume from 13.9 ~ 282cm ~ 3, the median 80cm ~ 3. None of the patients showed distant metastases.
