Photodynamic therapy: Toward a systemic computational model

Publication date: Available online 30 October 2018Source: Journal of Photochemistry and Photobiology B: BiologyAuthor(s): N. López-Marína, R. Mulet, R. RodríguezAbstractWe have designed a systemic model to understand the effect of Photodynamic Therapy (PDT) on long time scales. The model takes into account cell necrosis due to oxygen reactive species, cell apoptosis through the caspase pathway and the competition between healthy and tumor cells. We attempted to describe the system using state of the art computational techniques (necrosis and apoptosis) and simple models that allow a deeper understanding of the long time scale processes involved (healing and tumor growth). We analyzed the influence of the surface and tumor depth on the effectiveness of different treatment plans and we pr...
