The repeated treatment of targeted therapy in the treatment of skin melanoma

Currently, patients with disseminated forms of skin melanoma have limited treatment options. The most effective treatments, according to research, are targeted drugs BRAF/MEK inhibitors when a mutation in exon 15 of the BRAF gene is detected in tumor biopsy tissue and immune synapse modulators, specifically anti-CTLA-4 and anti-PD-1 drugs. Both classes of drugs show a significant benefit in overall and progression-free survival, but convincing data on their effectiveness in second and subsequent lines of therapy are still lacking. Most often, with the progression of disseminated skin melanoma during tyrosine kinase inhibitor therapy, a dual immunotherapy combination is used. In the event of further progression, due to the limited treatment options, clinical oncologists face questions about the possibility of returning to targeted therapy, changing tyrosine kinase inhibitor drugs, or using the initial combination, and their impact on progression-free survival in choosing treatment strategies for such patients, as well as the potential use of BRAF/MEK inhibitors. Assessing the reuse of tyrosine kinase inhibitor drugs is a highly relevant issue in clinical oncology.
