Treatment of basal cell carcinoma: An overview

Abstract

Basal cell carcinoma (BCC) is the most common cutaneous cancer worldwide, but accounts for only 2–4% of skin cancers in Asian population. Tumor characteristics such as size, location, pathology, and risk of recurrence, as well as treatment tolerability, cost, and patient preference influence the selection of treatment. The goal of treatment is complete tumor removal in superficial/locally invasive BCCs and prolongation of survival in the rare setting of metastatic BCC. Various treatment options available include conventional surgical excision, Mohs micrographic surgery, cryosurgery, electrodesiccation and curettage, topical application of imiquimod or 5-fluorouracil, and photodynamic, and radiotherapy. Surgical excision and Mohs surgery are preferred because of low recurrence rate and the possibility to evaluate the clearance through histology. In the treatment of metastatic or locally advanced lesions, hedgehog pathway inhibitors and the recently approved drug cemiplimab can be beneficial. Sun protection and regular skin self-checks are recommended for all patients with BCC. This literature review gives an overview of the treatment of BCC.
