Abstract

The therapeutic landscape for melanoma has evolved drastically in the past decade. Currently, immune checkpoint inhibitors and small-molecule inhibitors targeting the mitogen-activated protein kinase (MAPK) pathway are the two mainstay therapies for BRAF mutant advanced melanoma. Although MAPK dependence has been variably demonstrated in melanomas lacking BRAF mutations, definitive evidence of benefit with MAPK inhibitors has not been demonstrated. Thus, in the BRAF 'wild-type' setting, immune checkpoint inhibitors are the standalone option(s). In the BRAF mutant setting, there is no definitive evidence prioritizing one therapeutic modality over another. Herein, we review the updated data of the pivotal phase III randomized controlled trials that established the standard-of-care first-line treatment for advanced melanoma, as it provides insights into long-term benefit, which is a major factor in therapy selection. We discuss the clinical considerations for choosing between these therapies in the front-line setting and beyond, specifically for patients with BRAF mutant melanoma based on currently available evidence. We have previously proposed a time-dependent resistance paradigm in which future therapeutic development strategies can be rooted. We also discuss how these Food and Drug Administration (FDA)-approved therapeutic modalities are being pursued earlier in the course of disease management, namely in adjuvant and neoadjuvant settings. FDA-approved interlesional oncolytic virotherapy in the modern era is also briefly discussed.

摘要

在过去的十年中,黑色素瘤的治疗格局发生了巨大变化。目前,针对 BRAF 突变的晚期黑色素瘤,免疫检查点抑制剂和靶向丝裂原活化蛋白激酶(MAPK)通路的小分子抑制剂是两种主要的治疗方法。尽管在缺乏 BRAF 突变的黑色素瘤中已经证明了 MAPK 依赖性,但尚未证明 MAPK 抑制剂具有明确的获益证据。因此,在 BRAF“野生型”环境中,免疫检查点抑制剂是唯一的选择。在 BRAF 突变环境中,没有明确的证据表明一种治疗方法优于另一种。在此,我们回顾了关键的 III 期随机对照临床试验的最新数据,这些试验确立了晚期黑色素瘤的标准一线治疗方法,为长期获益提供了见解,这是治疗选择的一个主要因素。我们讨论了在一线治疗环境及其他环境中,基于当前可用证据,在这些疗法之间进行选择的临床注意事项,特别是对于 BRAF 突变型黑色素瘤患者。我们之前提出了一个时间依赖性耐药的范例,未来的治疗开发策略可以以此为基础。我们还讨论了这些已获得美国食品和药物管理局(FDA)批准的治疗方法在疾病管理过程中的更早阶段是如何被采用的,即在辅助和新辅助治疗环境中。我们还简要讨论了现代时代获得 FDA 批准的肿瘤内溶瘤病毒治疗。
