Targeted Drug Delivery in Periorbital Non-Melanocytic Skin Malignancies

Benedetta Tirone et al. Bioengineering (Basel). .

Abstract

Targeted drug delivery has emerged as a transformative approach in the treatment of periorbital skin malignancies, offering the potential for enhanced efficacy and reduced side effects compared to traditional therapies. This review provides a comprehensive overview of targeted therapies in the context of periorbital malignancies, including basal cell carcinoma, squamous cell carcinoma, sebaceous gland carcinoma, and Merkel cell carcinoma. It explores the mechanisms of action for various targeted therapies, such as monoclonal antibodies, small molecule inhibitors, and immunotherapies, and their applications in treating these malignancies. Additionally, this review addresses the management of ocular and periocular side effects associated with these therapies, emphasizing the importance of a multidisciplinary approach to minimize impact and ensure patient adherence. By integrating current findings and discussing emerging trends, this review aims to highlight the advancements in targeted drug delivery and its potential to improve treatment outcomes and quality of life for patients with periorbital skin malignancies.

Keywords: Merkel cell carcinoma; basocellular carcinoma; periorbital skin malignancies; squamocellular carcinoma; targeted drug delivery systems; targeted drugs.

Erlotinib is a small-molecule inhibitor that targets the epidermal growth factor receptor (EGFR), a transmembrane tyrosine kinase receptor involved in cell proliferation and survival. It works by competitively inhibiting the ATP-binding site of EGFR’s tyrosine kinase domain. By blocking EGFR activation, erlotinib prevents the downstream signaling pathways (such as the RAS-RAF-MEK-ERK and PI3K-AKT pathways) that promote tumor cell growth, survival, and proliferation.
