Real-life evaluation of the treatment of actinic keratoses by textile photodynamic therapy (FLUXMEDICARE® device).

INTRODUCTION:Actinic keratoses (AK) are a common precancerous skin condition in dermatology practice. Photodynamic therapy (PDT) with ALA or MAL is an effective but painful treatment of fields of cancerization particularly when conventional illumination sources and irradiation rates are used. Two prior studies showed that illumination with textile PDT was not inferior to conventional PDT. FLUXMEDICARE® (FLX-PDT) is the first medical device marketed with textile based lighting . We performeda real-life study to evaluate efficacy and tolerance of this device. METHODS:We carried out a single-center retrospective study. We collected data from patients treated with FLX-PDT with MAL for AKs localized on scalp and temples between November 2018 and November 2019. The primary endpoint was complete clearance rate (CR) at 3 months-follow up. RESULTS:Data of 39 patients were reviewed in the study, with a total of 417 AKs. The CR rate was 72.6 % (95 %CI 67.9-77.0) at 3 months-follow up and 67.5 % (95 %CI 61.2-73.3) at 6 months-follow up. The median pain felt during the session was 0 and there wasn't erythema after the session for 64.1 %. CONCLUSION:Our real-life study confirms efficacy and safety of textile PDT by FLUXMEDICARE device in the treatment of scalp and temples AKs, with excellent tolerance and minimal pain reported.
