Advances in Immunotherapy and Targeted Therapy of Malignant Melanoma.

Malignant melanoma (MM) is a malignant tumor, resulting from mutations in melanocytes of the skin and mucous membranes. Its mortality rate accounts for 90% of all dermatologic tumor mortality. Traditional treatments such as surgery, chemotherapy, and radiotherapy are unable to achieve the expected results due to MM's low sensitivity, high drug resistance, and toxic side effects. As treatment advances, immunotherapy and targeted therapy have made significant breakthroughs in the treatment of MM and have demonstrated promising application prospects. However, the heterogeneity of tumor immune response causes more than half of patients to not benefit from clinical immunotherapy and targeted therapy, which delays the patient's condition and causes them to suffer adverse immune events' side effects. The combination of immunotherapy and targeted therapy can help improve therapeutic effects, delay drug resistance, and mitigate adverse effects. This review provides a comprehensive overview of the current development status and research progress of immune checkpoints, targeted genes, and their inhibitors, with a view to providing a reference for the clinical treatment of MM.
