[BRAF-MEK inhibitor therapy in melanoma]

We investigated the efficacy and safety of vemurafenib+cobimetinib (V+C) and dabrafenib+trametinib (D+T) based on real-life data. From 2015 and 2018 we have selected 118 BRAF-mutated metastatic melanoma patients, treated with V+C and D+T in our institute. We retrospectively analyzed the overall response rate (ORR), the progression-free survival (PFS), the overall survival (OS) and the adverse events of the therapies. The median follow-up time was 18 months (3-43) with V+C and 12 months (3-43) with D+T. The median PFS was 8 months in the V+C and 8.5 months in the D+T group. Median OS was 18 months in V+C group and 12 months with D+T. The ORR was revealed to be 82% in D+T group and 76% in V+C group. Each combination displayed a slightly different safety profile. In our retrospective analysis both BRAF-MEK inhibitor combination therapies showed favorable efficacy with a slightly different spectrum of toxicity profile.
