为了评估成人恶性胶质瘤在体外照射后近距离放疗的剂量效应关系,对这类病人进行了一时性植入~(125)Ⅰ的推量放疗研究。 旧金山加利福尼亚大学自1987年6月以来在该项研究中,采用了准标器箱进行相互垂直的放射照像技术,以此检验植入脑内的放射源位置,并制出剂量-体积矩形图。对自1987年6月至1992年12月间进行过近距离推量放疗的成人恶性胶质瘤病例的肿瘤体积进行了重新描绘,旨在使该项研究的前后标准统一,并对其剂量-体积矩形图进行再计算。对各种病人及其治疗参数进行了单变量及多变量分析,以此评估剂量因素对
To evaluate the dose-response relationship of brachytherapy in adult glioblastoma after brachytherapy in vitro, we performed a bolus radiotherapy study of ~ (125) I in this group. In the study, the University of California, San Francisco, since June 1987, a quasi-standard box was used for vertical radiography to test the position of the radioactive source implanted in the brain and to create a dose-volume rectangular chart . Tumor volumes of adult glioblastoma cases treated with brachytherapy at a brachytherapy from June 1987 to December 1992 were redrawn to align the pre- and postmortem criteria for this study and to quantify the dose-volume Rectangular chart recalculation. Univariate and multivariate analyzes were performed on various patients and their treatment parameters to assess the effects of dose factors
