在某些脑恶性星形细胞瘤患者中通过~(125)碘籽植入间质的近距疗法,存活期已超过一般预料,Laperriere医师报告39例随机接受标准外照射加间质内近距疗法~(125)碘籽植入的患者中,中数存活达到64wk。在神经外科医师手术后转来的合适患者中,随机分为在5wk内分25份接受50Gy外照射及外照射加~(125)碘籽植入,即在肿瘤边缘再增加60Gy。~(125)碘籽植入的方法是使用一定向的头支架;
In patients with certain brain malignancies, brachytherapy with 125 Iodine seed implantation has surpassed normal expectations for survival. Dr. Laperriere reported that 39 patients were randomized to standard external exposure plus interstitial proximity. Among the patients treated with 125I seeds, the median survival was 64wk. Among the appropriate patients who were transferred after surgery by neurosurgeons were randomly assigned to receive 50 Gy external irradiation and external irradiation plus 125 iodine seeds within 5 wk, ie, 60 Gy at the edge of the tumor. ~ (125) Iodine seed implantation method is to use a certain head stent;
