Abstract

About half of all cutaneous melanomas harbor activating mutations in the BRAF oncogene. Dependence on this pathway makes the tumors vulnerable to BRAF (and downstream MEK) inhibition, and three drug combinations are approved to target this vulnerability in advanced melanomas with BRAFV600 mutations. Responses to BRAF/MEK inhibitors are usually fast, but durability of response can be limited. Five-year data from BRAF/MEK inhibitors show long-term survival benefit for a third of the patients. There is a wide variety of known mechanisms of resistance to BRAF/MEK inhibition, such as mitogen-activated protein kinase reactivation, activation of parallel pathways, alterations in cell-cycle regulation, and non-genetic resistance mechanisms. Strategies that have been explored to overcome these mechanisms include alternative dosing regimens, addition of another kinase inhibitor, and use of anti-PD-1 immunotherapy either in combination or post-relapse on BRAF/MEK inhibitor therapies.

摘要

大约一半的皮肤黑色素瘤存在 BRAF 癌基因的激活突变。对该途径的依赖性使肿瘤容易受到 BRAF(和下游 MEK)抑制的影响,并且有三种药物联合方案被批准用于靶向具有 BRAFV600 突变的晚期黑色素瘤的这种脆弱性。对 BRAF/MEK 抑制剂的反应通常很快,但反应的持久性可能有限。BRAF/MEK 抑制剂的 5 年数据显示,三分之一的患者有长期生存获益。已知有多种对 BRAF/MEK 抑制的耐药机制,例如丝裂原活化蛋白激酶的再激活、平行途径的激活、细胞周期调控的改变以及非遗传耐药机制。为克服这些机制而探索的策略包括改变给药方案、添加另一种激酶抑制剂,以及在 BRAF/MEK 抑制剂治疗后或复发后使用抗 PD-1 免疫治疗。
