What is one of the challenges associated with VTP therapy?

One of the challenges associated with Vascular Targeted Photodynamic (VTP) therapy is the potential for adverse reactions and photosensitivity. VTP therapy utilizes photosensitizers that, when activated by specific wavelengths of light, generate reactive oxygen species to target blood vessels associated with tumors. While this can effectively destroy cancerous cells, patients may experience side effects, including skin reactions or systemic photosensitivity, making them more susceptible to adverse effects from light exposure following treatment.

These reactions can lead to discomfort, impose restrictions on a patient’s activities post-treatment, and create a need for additional patient education and support to manage these side effects. Understanding and managing these potential adverse reactions is crucial for both patient compliance with therapy and the overall success of VTP treatment.
