Photodynamic therapy with 5‐aminolevulinic acid in actinic cheilitis: an 18‐month clinical and histological follow‐up

Abstract

PDT represents a moderately effective treatment modality in AC. Optimization of treatment procedure and protocols is still needed for higher response rates to be achieved. Moreover, the high treatment cost should be given consideration. Further long-term follow-up studies are needed for assessment of clinical and histological very late recurrences that could be expected after PDT.
