高级别胶质瘤治疗后生存评估 ——基于增强MRI和IDH基因表型的初步研究
发布时间:2021-10-28 17:53
第一部分残腔外新增强化有助于改善高级别胶质瘤治疗后生存评估目的:高级别胶质瘤(HGG)经过标准化治疗后预后仍然较差,残腔外新增强化对预后的影响尚无定论。本研究旨在探讨残腔外新增强化是否有助于改善经标准化治疗后HGG生存预后的评估效能。方法:本研究回顾性分析142例HGG。将残腔外新增强化,包括新增室管膜下强化(n SVZE)和远处新增强化病灶(n DE),常规MRI特征和临床因素均纳入单因素分析。然后采用多因素分析评估以上各种因素对无进展生存期(PFS)和总生存期(OS)的预后判断作用。采用受试者工作特征曲线(ROC)比较将n SVZE和n DE联合其他预后因素的诊断效果。结果:该组病例中位随访时间为24(21-28)个月。中位PFS和OS分别为345(382-538)天、540(561-720)天。单因素分析显示:组织病理学分级(P=0.008)、n DE(P=0.0001)及n SVZE(P<0.0001)是影响PFS的不良预后因素。同样的,组织病理学分级(P=0.017)、n DE(P<0.0001)及n SVZE(P<0.0001)是影响OS的不良预后因素。多...
