摘要: 目的 评价BRAF抑制剂维莫非尼(vemurafenib)治疗难治性颅咽管瘤(CP)的疗效和不良反应,增加临床用药经验。 方法分析 2例难治性CP的治疗过程并随访3~5年,评价药物疗效和不良反应。结合文献,提出CP治疗的新流程。结果 1)2例成年乳头型CP患者,多次手术和放射治疗难以控制肿瘤,临床处理困难。2)基因检测显示肿瘤存在BRAF-V600E突变。患者接受维莫非尼治疗6.5~7.5个月,肿瘤体积缩小95%~99 %。停药后随访3~5年,残留病灶稳定。3)主要不良反应为皮疹,呈剂量依赖性。4)文献报道33/34例患者治疗效果良好,肿瘤体积缩小50%~100%。结论 BRAF抑制剂维莫非尼能有效治疗BRAF-V600E突变导致的难治性CP,不良反应可耐受。药物治疗或许会改变CP将来的诊治流程。

Abstract: Objective To evaluate the efficacy and adverse reactions of BRAF inhibitor vermorafenib on the treatment of refractory craniopharyngioma carrying BRAF-V600E mutation. Methods Clinical data of two patients with refractory craniopharyngiomas (CP) were recorded and reviewed. The patients were followed up for 3-5 years. Literature on CPs receiving BRAF or BRAF/MEK therapy was reviewed. Results 1)Papillary CP progressed after multiple operations and radiotherapy in two patients. Further treatments were very difficult. 2)The presence of BRAF-V600E mutation in the tumor was confirmed, and vermorafenib was administered for 6.5-7.5 months. Tumor volumes remarkably shrank by 95%-99%. No tumor relapse was observed during the follow-up of 3-5 years after discontinuation of vemurafenib. 3)The main adverse reaction was rash, which was dose dependent. 4)Literature review showed the volume shrank by 50%-100% in 33/34 tumors during BRAF or BRAF/MEK inhibitor therapy. Conclusions BRAF inhibitor vemurafenib is effective in treating refractory craniopharyngioma carrying BRAF-V600E mutation with endurable side effects, which may bring some changes to the management of CP in future.
