How We Perform Photodynamic Therapy MAL in Clinical Practice
Many clinical trials have been reported on MAL-PDT for treating nonmelanoma skin cancer (NMSC), and acne vulgaris. Although response rates are high for NMSC, they do not match the response rates of (Mohs’ micrographic) surgery, especially for deeper lesions. The delivery of sufficient (precursor of) PpIX and light to the full depth of the lesion and sufficient supply of oxygen are critical in topical PDT. Optimization of these factors to improve the response rates for the deeper lesions is an area under investigation. Beside this technical limitation, pain associated with PDT is an important patient-related limitation of PDT. Although a lot of research has been done into the efficiency of PDT, more work needs to be done on the effect of various treatment variables on the efficiency and adverse effects of PDT in order to develop an optimum treatment protocol for both NMSC and acne vulgaris.
