Summary
Brief summary (as posted)
The purpose of this study is to compare two different therapies for actinic keratoses in organ transplant recipients with regard to efficacy and tolerability. The investiagtors are planning to examine treatment with Imiquimod 5% cream versus treatment with Methyl-aminolaevulinate 16% cream and subsequent irradiation with red light, so-called photodynamic therapy, in this patients' group. A secondary objective of our study is to investigate the reduction in the field cancerisation after both treatments using fluorescence diagnostic method and digital imaging.

- description
- Methyl-aminolaevulinate 16% cream (Metvix 160mg/g cream) will be applied 1 mm thick on the treated area, which has a maximal diameter of 8 cm2, and will be covered with a semipermeable dressing (Suprasorb F, Lohmann \& Rauscher, Vienna, Austria)for 3 hours. Afterwards the cream leftovers will be removed by 0.9% NaCl solution. Following the treated area will be irradiated with heat-free visible red light at a peak wavelength of 630 nm with a single dose of 37 J/cm2 (Actilite model: CL128, PhotoCure, Norway). This treatment will be repeated in two weeks.
