Treatment Considerations to Overcome the Barriers Associated with Skin Cancer Targeting

Abstract

Abstract: Skin cancer is a prevalent and diverse group of malignancies affecting the skin, with three primary types: basal cell carcinoma, squamous cell carcinoma, and melanoma. Each subtype varies in terms of its histological origin, behavior, and potential for metastasis. Despite advances in treatment, skin cancer poses challenges due to biological barriers that hinder drug delivery, multidrug resistance mechanisms that limit treatment effectiveness, and the complex interplay of genetic alterations driving tumorigenesis. Current treatment strategies encompass a spectrum of approaches, including chemotherapies, immunotherapies, gene therapies, and innovative techniques such as photothermal therapy, iontophoretic therapy, electroporation therapy, microneedle array therapy, and nanotechnology-based treatments. The latter involves liposomes, niosomes, carbon nanotubes, dendrimers, hydrogels, and gold nanoparticles, all tailored to enhance drug delivery and therapeutic efficacy. Additionally, herbal drug-based therapy harnesses the potential of natural compounds to target various aspects of skin cancer progression. This review provides an overview of skin cancer types, challenges in treatment, and an extensive exploration of current therapeutic strategies, highlighting the everevolving landscape of innovative approaches that promise to transform how skin cancer is managed.
