Nonmelanoma Skin Cancer: Photodynamic Therapy


Topic Overview

Photodynamic therapy (PDT) is being studied as a treatment for nonmelanoma skin cancer. PDT is a process of applying a medicine to a skin cancer and then shining a special laser light on it.

Results of early studies with the medicine 5-aminolevulinic acid (ALA) show that topical PDT may be effective in treating actinic keratoses on the face and scalp, squamous cell carcinoma in situ (Bowen's disease), and superficial basal cell carcinomas. Studies report good results with skin appearance after treatment and a low rate of side effects.1

Studies of PDT with methyl aminolevulinate (MAL) found that this treatment was as effective as cryosurgery for actinic keratoses and squamous cell carcinoma in situ (Bowen's disease).2
