摘要
目的评价伽玛刀治疗颅内转移瘤的疗效。方法回顾性分析476例接受伽玛刀治疗的转移瘤患者。伽玛刀治疗中位处方剂量20Gy(13～30Gy),等剂量曲线80%。结果所有接受伽玛刀治疗的转移瘤患者中3个月生存率为91.2%(434/476),6个月生存率75.4%(359/476),12个月生存率38.0%(181/476)。结论颅内转移瘤接受伽玛刀治疗可以很好地提高生存期,提高生活质量,复发的患者仍可以再次接受伽玛刀治疗。
Objective To assess the efficacy of gamma knife radiosurgery （GKRS） for brain metastases. Methods A total of 476 cases with brain metastasis who undergone GKRS were retrospectively analyzed. The median prescription dose was 20Gy （ 13 -30Gy） delivered to the 80% isodose line. Results Overall survival rate in 3 months was 91.2% , in 6 months was 75.4% ,in 12 months was 38.0%. Conclusion GKRS to the brain metastases achieves better outcome. Patients of recurrent metastases can obtain repeat therapy with gamma knife.
