Fractionated aminolevulinic acid–photodynamic therapy provides additional evidence for the use of PDT for non‐melanoma skin cancer

Abstract

ALA-PDT using a twofold illumination scheme of 20 plus 80 J/cm(2) separated by a 2-h dark interval leads to high complete response rates at 2 years and can be regarded as an evidence-based treatment modality for superficial growing non-melanoma skin cancer and the (pre)malignant AK. The Rotterdam fractionated approach should be included in future guidelines.
