Glioblastoma is one of the most difficult to treat and most aggressive brain tumors, having a poor survival rate. The use of non-invasive modulated electro-hyperthermia (mEHT) and Tumor Treating Fields (TTF) devices has been introduced in the last few decades, both of which having proven anti-tumor effects.
A meta-analysis of randomized and observational studies about mEHT and TTF was conducted.
A total of seven and fourteen studies about mEHT and TTF were included, with a total number of 450 and 1309 cases, respectively. A 42% [95% confidence interval (95% CI): 25-59%] 1-year survival rate was found for mEHT, which was raised to 61% (95% CI: 32-89%) if only the studies conducted after 2008 were investigated. In the case of TTF, 1-year survival was 67% (95% CI: 53-81%). Subgroup analyses revealed that newly diagnosed patients might get extra benefits from the early introduction of the devices (mEHT all studies: 73% vs. 37%, = 0.0021; mEHT studies after 2008: 73% vs. 54%, = 0.4214; TTF studies: 83% vs. 52%, = 0.0083), compared with recurrent glioblastoma.
Our meta-analysis showed that both mEHT and TTF can improve glioblastoma survival, and the most benefit may be achieved in newly diagnosed cases.
胶质母细胞瘤是最难治疗且侵袭性最强的脑肿瘤之一，生存率很低。在过去几十年中，已引入了非侵入性调制式电超温治疗（mEHT）和肿瘤电场治疗（TTF）设备，这两种设备均已证明具有抗肿瘤作用。
对关于mEHT和TTF的随机和观察性研究进行了荟萃分析。
分别纳入了7项和14项关于mEHT和TTF的研究，病例总数分别为450例和1309例。发现mEHT的1年生存率为42%[95%置信区间（95%CI）：25 - 59%]，如果仅调查2008年后进行的研究，该生存率提高到61%（95%CI：32 - 89%）。对于TTF，1年生存率为67%（95%CI：53 - 81%）。亚组分析显示，与复发性胶质母细胞瘤相比，新诊断患者可能会从早期引入这些设备中获得额外益处（mEHT所有研究：73%对37%，P = 0.0021；2008年后的mEHT研究：73%对54%，P = 0.4214；TTF研究：83%对52%，P = 0.0083）。
我们的荟萃分析表明，mEHT和TTF均可提高胶质母细胞瘤患者的生存率，且在新诊断病例中可能获得最大益处。
