Oncolytic virotherapy with mutants derived from Herpes simplex virus (HSV) type 1 exhibit significant antitumor effects in preclinical models. Several mutants have now been tested in clinical trials for a variety of cancer types, and all have been found to be safe. While there have been hints of antitumor efficacy with prolonged survival in some cases compared with historical controls, dramatic responses have been elusive. We review the clinical experience published to date and discuss some of the biologic factors that may be limiting for virus infection and spread, as well as new strategies currently under development to enhance antitumor efficacy.
溶瘤病毒疗法使用从单纯疱疹病毒 1 型(HSV-1)衍生的突变株,在临床前模型中显示出显著的抗肿瘤作用。目前已有多种突变株在各种癌症类型的临床试验中进行了测试,均被证实是安全的。虽然与历史对照相比,某些情况下的生存期延长提示具有抗肿瘤疗效,但仍难以达到显著反应。我们回顾了迄今为止发表的临床经验,并讨论了一些可能限制病毒感染和传播的生物学因素,以及目前正在开发的增强抗肿瘤疗效的新策略。
