如何治疗耐药性罕见妇科癌症?免疫疗法Avelumab表现出众

2020-05-29 Allan MedSci原创

妊娠滋养细胞肿瘤(GTT)是一种非常罕见的妇科癌症,发生于怀孕期间或之后。

妊娠滋养细胞肿瘤(GTT)是一种非常罕见的妇科癌症,发生于怀孕期间或之后。GTT是由受孕期间子宫内膜异常生长发展而来。Avelumab是一种检查点抑制剂,可以阻断肿瘤细胞上的PD-L1。由于GTT过表达PD-L1,使Avelumab成为治疗GTT的潜在疗法。

一项小型II期研究显示,Avelumab(Bavencio)具有治愈GTT的可能性,这些结果将在2020年美国临床肿瘤学会(ASCO)年会的上披露。在这项研究中,对甲氨蝶呤或放线菌素-D耐药的15例GTT患者使用avelumab(Bavencio)治疗,其中有8例(53%)在随访29个月时没有疾病复发迹象。如果疾病在12个月后仍未复发,并且对人绒毛膜促性腺激素(hCG,GTT的生物标志物)的监测已完成,研究人员则认为患者已被治愈。

ASCO主席Howard A. Burris博士说:“鉴于无复发患者比例和良好的安全性数据,Avelumab值得进一步研究”。
