[Management of toxicities of BRAF inhibitors and MEK inhibitors in advanced melanoma].

Major therapeutic advances have been made recently in the treatment of metastatic melanoma, due to the development of targeted therapies, namely BRAF and MEK inhibitors, in patients with BRAF V600 mutation. Combinations of vemurafenib+cobimetinib, dabrafenib+trametinib, et encorafenib+binimetinib, evaluated in coBRIM, COMBI-d/COMBI-v and COLUMBUS trials respectively have been approved in this indication. Toxicities induced by combination therapies are different from those reported with monotherapies, in terms of frequency and intensity. Physicians who treat melanoma patients thus face news issues relating to prevention, detection and treatment of these adverse events. This paper summarizes tolerance data from the three pivotal trials (coBRIM, COMBI-v and COLUMBUS) and issues recommendations for the specific management of main toxicities, based on experts' opinion. We discuss dermatological, ophthalmological, cardiovascular, digestive, musculoskeletal, renal and general toxicities and propose a timetable for examinations to be performed before and during treatment.
