Recent progress in topical and transdermal approaches for melanoma treatment

The global incidence of melanoma, the most lethal form of skin cancer, continues to escalate, emphasizing the urgent need for more effective therapeutic strategies. This review assesses the latest advancements in topical and transdermal drug delivery systems, positioning them as promising alternatives. These systems allow for the direct application of therapeutic agents to tumor sites, enhancing drug effectiveness, improving patient compliance, and reducing systemic toxicity. Specifically, innovations such as nanoparticles, microneedles, and vesicular systems are explored for their potential to optimize topical and localized drug delivery. By incorporating a graphical overview of these drug delivery vehicles, we visually underscore their roles in enhancing therapeutic outcomes across various treatment categories such as chemotherapy, immunotherapy, phototherapy, phytotherapy, and targeted therapy. This article critically evaluates recent breakthroughs, addresses the current challenges faced by researchers, and explores the future directions of topical and transdermal approaches in melanoma management. By presenting a summary of the latest research and predicting future trends, this review aims to inform ongoing developments and encourage further innovation in strategies for treating melanoma.Graphical abstractIllustration of the drug delivery carriers used for the melanoma topical and transdermal treatment approaches since 2016
