Abstract
Background The efficacy and safety of methyl aminolevulinate daylight photodynamic therapy (MAL DL-PDT) for actinic keratosis (AK) treatment has previously been demonstrated in several studies. Objective To evaluate patient-reported outcomes, effectiveness and tolerability of patient self-applied MAL DL-PDT. Patients and methods An open study was conducted in Germany in patients with thin or non-hyperkeratotic and non-pigmented AK. At baseline, the investigator delimited the target anatomical area and skin preparation was discretionary. On day 1, the patient performed MAL DL-PDT at home, in accordance with instructions (after applying sunscreen and skin preparation by abrasive pad). Patient questionnaires were completed on day 1 and 3 months post-treatment. Effectiveness was assessed by investigator at 3 months. Pain and adverse events (AE) were recorded. Results Patients (n = 50) were mostly elderly (mean age: 73.4 years) men (86%). After treatment on day 1, 94% of patients were overall satisfied or very satisfied with the treatment and 98% found the instructions convenient. At 3 months, most patients were satisfied or very satisfied with treatment effectiveness (88%) and aspect of their skin (80%). At 3 months, 62% of overall lesions were completely clear. The main related AEs were mild and expected (erythema, procedural pain and skin burning sensation). Conclusions Patient self-application of MAL DL-PDT resulted in high levels of patient satisfaction, effectiveness and tolerability.
