Recent developments in immunotherapy have prolonged overall survival in metastatic melanoma with the possibility to reach a long-term benefit. Targeted therapies based on BRAF and MEK inhibition also seem to have a long-term beneficial effect, which is more evident in patients with favorable baseline characteristics, namely normal levels of lactate dehydrogenase, without brain metastases, and low tumor burden. This long-term benefit of targeted therapies might be related to an immune-modulation: indeed BRAF and MEK inhibitors affect tumor microenvironment and immune surveillance, and it has been shown that patients with complete response to targeted treatment have a pre-existing favorable immunologic signature.
免疫疗法的最新进展延长了转移性黑色素瘤患者的总生存期,并有可能带来长期益处。基于BRAF和MEK抑制的靶向治疗似乎也具有长期有益效果,这在具有良好基线特征的患者中更为明显,即乳酸脱氢酶水平正常、无脑转移且肿瘤负荷低的患者。靶向治疗的这种长期益处可能与免疫调节有关:事实上,BRAF和MEK抑制剂会影响肿瘤微环境和免疫监视,并且已经表明,对靶向治疗完全缓解的患者具有预先存在的良好免疫特征。
