高級(jí)別膠質(zhì)瘤治療后生存評(píng)估 ——基于增強(qiáng)MRI和IDH基因表型的初步研究

第一部分殘腔外新增強(qiáng)化有助于改善高級(jí)別膠質(zhì)瘤治療后生存評(píng)估目的:高級(jí)別膠質(zhì)瘤(HGG)經(jīng)過(guò)標(biāo)準(zhǔn)化治療后預(yù)后仍然較差,殘腔外新增強(qiáng)化對(duì)預(yù)后的影響尚無(wú)定論。本研究旨在探討殘腔外新增強(qiáng)化是否有助于改善經(jīng)標(biāo)準(zhǔn)化治療后HGG生存預(yù)后的評(píng)估效能。方法:本研究回顧性分析142例HGG。將殘腔外新增強(qiáng)化,包括新增室管膜下強(qiáng)化(n SVZE)和遠(yuǎn)處新增強(qiáng)化病灶(n DE),常規(guī)MRI特征和臨床因素均納入單因素分析。然后采用多因素分析評(píng)估以上各種因素對(duì)無(wú)進(jìn)展生存期(PFS)和總生存期(OS)的預(yù)后判斷作用。采用受試者工作特征曲線(ROC)比較將n SVZE和n DE聯(lián)合其他預(yù)后因素的診斷效果。結(jié)果:該組病例中位隨訪時(shí)間為24(21-28)個(gè)月。中位PFS和OS分別為345(382-538)天、540(561-720)天。單因素分析顯示:組織病理學(xué)分級(jí)(P=0.008)、n DE(P=0.0001)及n SVZE(P<0.0001)是影響PFS的不良預(yù)后因素。同樣的,組織病理學(xué)分級(jí)(P=0.017)、n DE(P<0.0001)及n SVZE(P<0.0001)是影響OS的不良預(yù)后因素。多...
