Melanoma is the most aggressive of the skin cancers, with historically high rates of morbidity and mortality due to its resistance to traditional cytotoxic therapies. Recently, however, breakthroughs in new therapies have dramatically changed clinical outcomes of this disease. These advances emerged from an improved understanding of tumor oncogenesis and the interacting tumor microenvironment. Small molecules that target the oncogenic mitogen-activated protein kinase (MAPK) pathway, specifically the tyrosine kinase BRAF and its downstream signaling partner MEK, have demonstrated an improved overall survival and progression-free survival for BRAF-mutant melanoma. Additionally, manipulation of tumor immune surveillance by inhibitors of the immune suppressive programmed cell death 1 receptor (PD-1) and cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) pathways have recently demonstrated durable responses in various cancers by promoting an anti-tumor immune response. Application of these targeted and immune-modulatory therapies has shown promising outcomes in melanoma. Combinations of these therapies may hold promise to enhance responses further. In this review, we will discuss the current targeted therapies and immunotherapies, and review the results of combination studies and speculate on future treatment paradigms.
黑色素瘤是皮肤癌中最具侵袭性的一种,由于其对传统细胞毒性疗法的耐药性,其发病率和死亡率历来较高。然而,最近新疗法的突破极大地改变了这种疾病的临床结果。这些进展源于对肿瘤发生和相互作用的肿瘤微环境的更好理解。针对致癌丝裂原活化蛋白激酶(MAPK)途径的小分子,特别是靶向酪氨酸激酶 BRAF 及其下游信号伙伴 MEK 的小分子,已证明 BRAF 突变型黑色素瘤的总生存率和无进展生存率得到改善。此外,通过抑制免疫抑制程序性细胞死亡 1 受体(PD-1)和细胞毒性 T 淋巴细胞相关抗原 4(CTLA-4)途径的肿瘤免疫监视的操纵,最近通过促进抗肿瘤免疫反应,在各种癌症中显示出持久的反应。这些靶向和免疫调节疗法在黑色素瘤中的应用显示出有希望的结果。这些疗法的联合应用可能有望进一步提高疗效。在这篇综述中,我们将讨论目前的靶向治疗和免疫疗法,并回顾联合研究的结果,并对未来的治疗模式进行推测。
