记者从中山大学肿瘤防治中心获悉,该中心张力教授团队牵头开展的鼻咽癌免疫治疗研究取得重大突破。相关研究9月11日以快审通道的形式发表于《柳叶刀?肿瘤学》。香港大学教授Dora L W Kwong在同期评论中指出,这是迄今为止在鼻咽癌领域报道免疫治疗疗效最好的研究。

据悉,张力为该文章独立通讯作者,方文峰、杨云鹏、马宇翔、洪少东及广州中医药大学附属第一医院教授林丽珠为该文共同第一作者。方文峰表示,一直以来,晚期鼻咽癌仍以化疗为主,缺乏高效、低毒的靶向药物及新的治疗手段。因此寻找新的高效、低毒的治疗手段成为鼻咽癌研究领域的迫切任务。

张力教授团队于2012年启动首个晚期鼻咽癌一线治疗的III期临床试验,对比了顺铂联合吉西他滨与顺铂联合5氟尿嘧啶一线治疗复发或转移性鼻咽癌的疗效与安全性。结果显示,顺铂联合吉西他滨方案的中位无进展生存期,有效率、总生存期均优于传统的顺铂联合5氟尿嘧啶方案,从此确立了晚期鼻咽癌癌一线优选方案。但是,患者接受一线治疗后平均7个月左右会出现耐药,一旦发生耐药,则治疗选择非常有限,预后较差。

为了寻找更好的高效、低毒的治疗方案,张力教授团队于2016年起开展了两项临床研究,分别探索了PD-1单抗单药治疗一线化疗失败后的晚期鼻咽癌的一期临床研究,以及PD-1单抗联合化疗一线治疗晚期鼻咽癌的一期临床研究,评价其安全性及有效性。

该研究显示:单药治疗组,患者最佳总体有效率为34%,疾病控制率为59%;中位无疾病进展时间达到了5.6个月;PD-1单抗单药治疗引起的3度及3度以上和严重不良反应发生率均较低。联合治疗组,总体有效率达到91%,疾病控制率高达100%,中位起效时间为1.6个月。经过10.2个月的中位随访时间,目前联合治疗组的中位无疾病进展时间尚未达到,6个月及12个月无进展生存率分别为86%和61%。联合化疗组的毒性以化疗毒性为主,基本可管控。

张力表示,该研究为复发及转移性鼻咽癌的临床治疗提供了新的方案,未来免疫治疗可能改变鼻咽癌的治疗模式。目前,他的团队正带领全国多家医院进行PD-1单抗在晚期鼻咽癌两线治疗后的注册临床研究及化疗联合PD-1单抗对比化疗的一线适应症研究。
