视神经胶质瘤在小儿所有颅内肿瘤中占1～5%。对于这些肿瘤的处理目前仍有争论。报告1956-1977年18例视神经胶质瘤用外源性放射治疗。小儿均为视力低下,其中有5例为单眼盲。没有一例是单独视神经受损,其中8例视交叉受损,10例肿瘤已扩展到额叶和/或下丘脑。7例做了活组织检查,2例做了肿瘤探查术,7例部分切除。2名根据放射科所见作了放射治疗。照射剂量为5.5-6.5周内5000-6000拉德。在能评价的病人中,有78%的患儿视力减退或改善者得以稳定。10年存活率为73%。说明放射疗法对肿瘤的消退有一定的疗效。作者的印象是:对预后较
Optic gliomas account for 1 to 5% of all intracranial tumors in children. The treatment of these tumors is still debated. Report 1956-1977 18 cases of neurogenic glioma with exogenous radiation therapy. Children have low vision, of which 5 were monocular blind. In none of the cases, optic nerve alone was impaired, with 8 cases of optic chiasm impaired and 10 cases of tumors extended to the frontal and / or hypothalamus. Seven patients underwent biopsy, two underwent tumor exploration and seven underwent partial resection. Two people were treated according to radiology. Radiation dose of 5.5-6.5 radon for 5.5-6.5 weeks. In evaluable patients, 78% of children with visual impairment or improvement were stabilized. The 10-year survival rate was 73%. Radiation therapy shows that the tumor regression has a certain effect. The author’s impression is: the prognosis than
