AbstractPhotodynamic therapy (PDT) is an effective treatment option for the treatment of superficial basal cell carcinoma (sBCC). Recent publications have demonstrated that PDT with 7.8% 5-aminolaevulinic acid nanoemulsion-based gel (BF-200 ALA-PDT) is an effective and safe alternative for the treatment of sBCC). To investigate the efficacy and safety of 7.8% 5-aminolaevulinic acid nanoemulsion-based gel (BF-200 ALA)-PDT for the treatment of sBCC. A non-controlled, open-label single centre study was conducted. Patients received one PDT cycle with two PDT sessions one-week apart. In case that clinical-dermoscopy evaluation of treatment outcome revealed remaining lesions, a second PDT cycle was performed. The clinical results at the dermoscopy and fluorescence diagnosis level were histologically confirmed in all patients. Treatment response was evaluated 3, 6, and 12 months after last PDT session. A total of 31 patients (12 men and 19 women), with a median age of 63.74 years were included in this study. 3-month after PDT-session, 23/31 patients were complete responders (74.19%) after two BF-200 ALA -PDT sessions. Esthetic outcome was considered good-to-excellent. 5 Aminolevulinic acid 7.8% nanoemulsion-based gel (BF-200 ALA) PDT is an effective therapy option for the treatment of sBCC. Complete clearance rates were higher in those patients who received only one PDT cycle. These results show a similar tendency as shown in other publications.© 2020 Wiley Periodicals LLC.
