Dual and triple combination therapies with RAF inhibitors plus other targeted agents have demonstrated promising clinical utility in BRAFV600-mutant solid tumors. However, despite vertical inhibition at multiple nodes on the MAPK signaling pathway, resistant tumors emerge. Ahronian and colleagues show that in BRAF-mutant colorectal cancer, resistance involves reactivation of RAS/RAF/MEK/ERK signaling and may be overcome by newly emerging ERK inhibitors.
RAF抑制剂与其他靶向药物的双联和三联联合疗法已在BRAFV600突变实体瘤中显示出有前景的临床应用价值。然而,尽管在MAPK信号通路的多个节点进行了垂直抑制,但仍会出现耐药肿瘤。阿罗尼安及其同事表明,在BRAF突变型结直肠癌中,耐药涉及RAS/RAF/MEK/ERK信号的重新激活,并且可能被新出现的ERK抑制剂克服。
