【摘要】 报道４４例脑深部神经胶质瘤采用ＣＴ导向立体定向技术，用放射性胶体磷酸铬（３２Ｐ）进行瘤内放射治疗，其中３０例联合甲氨蝶呤（ＭＴＸ）瘤内化疗。术后经临床和ＣＴ随访６～４８月，结果：临床症状和体征消失１３例，改善２２例，无效或恶化９例。ＣＴ证实显效４例，有效２７例，微效４例，无变化４例，恶化５例。囊性较实质性效果为好，联合治疗较单纯内放疗效果好。作者认为，此法操作简单，效果确定，特别适用于深部和重要功能区的囊性神经胶质瘤，并对联合作用的机理和并发症进行了讨论。更多还原

【Abstract】 cases of deep brain gliomas treated with CT-guide stereotactic interstitial radiotherapy of ￣(32)P, among them 30 cases combined with Methotrexate(MTX)chemotherapy with 6￣48 months followed-up, All clinical symptoms disappered in 13, improved in 22, no effects in 9. There were no mortality and serious complications. Authours suggest that this method is safe and precise for treatment of gliomas in the deep cerebral and brain stem,it is best for cystic gliomas.This study also demostrated the combined interstitial radiaotherapy and chemotherapy is better than interstitial radiotherapy used only.更多还原
