对５０例胶质瘤患者实施伽玛刀治疗，肿瘤直径０８～８ｃｍ（平均３３５ｃｍ），肿瘤中心剂量２６７～６０Ｇｙ（平均３９５１Ｇｙ），覆盖病灶边缘的等剂量线为２０％～８０％（平均４０％）。结果表明，３７例随访１～２０个月（平均７８３个月），临床病灶改善２１例（５６７％），加重７例（１８９％），无变化９例（３４３％）；影像学随访１９例，病变消失３例（１５８％），缩小７例（３６８％），增大３例（１５８％），无变化６例（３１２％）。说明伽玛刀是治疗胶质瘤的一种有效手段。 Fifty patients with glioma underwent gamma knife radiosurgery. The tumor diameter ranged from 0.8cm to 8cm (mean, 3.35cm), and the tumor center dose ranged from 26.7g to 60Gy (average, 39.51Gy). The isodose coverage line 20% ~ 80% (average 40%). The results showed that 37 cases were followed up for 1 ~ 20 months (mean, 783 months), 21 cases (567%) were improved clinical symptoms, 7 cases (189%) were aggravated, 9 cases (343) (198%), 7 cases (368%) were reduced, 3 cases (158%) were enlarged, 6 cases were unchanged (312%), ). Gamma knife that is an effective means of treatment of glioma.
