ATP-competitive RAF inhibitors elicit profound but often temporary antitumor responses in patients with BRAF-mutant melanoma. Analysis of tumor samples collected at the time of disease progression indicates that alterations within the extracellular signal-regulated kinase (ERK) pathway that result in reactivation of ERK signaling are present in most patients. Mutations in the phosphoinositide 3-kinase/AKT pathway that enhance the adaptive response to RAF inhibitors also contribute to RAF inhibitor resistance in a subset of patients.
三磷酸腺苷(ATP)竞争型 RAF 抑制剂在 BRAF 突变型黑色素瘤患者中引发显著但往往是短暂的抗肿瘤反应。对疾病进展时采集的肿瘤样本的分析表明,大多数患者存在导致 ERK 信号重新激活的细胞外信号调节激酶(ERK)通路改变。磷酸肌醇 3-激酶/AKT 通路中的突变增强了对 RAF 抑制剂的适应性反应,也导致了一部分患者对 RAF 抑制剂产生耐药性。
