What is the primary purpose of Vascular Targeted Photodynamic (VTP) therapy?

The primary purpose of Vascular Targeted Photodynamic (VTP) therapy is to selectively destroy cancerous tissues. VTP utilizes a photosensitizing agent that preferentially accumulates in cancerous tissues and is activated by a specific wavelength of light. This process generates reactive oxygen species that lead to localized cell death and damage to the tumor vasculature, effectively targeting and destroying the cancerous cells while sparing the surrounding healthy tissue.

This selective destruction is central to the efficacy of VTP, as it aims to minimize damage to healthy cells and tissues while maximizing the therapeutic effect on the tumor. Thus, the capability of VTP to precisely attack cancerous areas distinguishes it from other therapeutic modalities.
