Aminolevulinic Acid 20% Solution Combined With Photodynamic Therapy for Treatment of Actinic Keratoses: A Review.

Actinic keratoses (AK) are lesions with potential to transform into nonmelanoma skin cancers. Numerous methods are available for treatment of AK. Here, we review clinical trial data on the use of photodynamic treatment combined with the sensitizing agent aminolevulinic acid 20% solution (ALA-PDT) for AK management. Although treatment guidelines for AK vary in their specific recommendations, efficacy of ALA-PDT is considered comparable or better relative to other FDA-approved treatments for AK. It is generally well tolerated and has a very acceptable long-term safety profile. ALA-PDT is typically recommended for patients who have multiple AKs and is associated with improved cosmetic outcomes compared with cryotherapy. Patients who undergo treatment with ALA-PDT should receive thorough education regarding the risks and benefits of treatment, the treatment regimen and the importance of adhering to it, how to manage local reactions, and signs and symptoms that warrant further evaluation.
