Terapia fotodinâmica de câncer – Revisão bibliográfica

Abstract

Photodynamic therapy (TFD) is an innovative medical treatment that uses the interaction of light, oxygen and a chemical compound called a photosensitizer to treat various health conditions. The process begins with the application of a photosensitizer to the target tissue. This compound has the ability to absorb light of a specific wavelength and transfer this energy to the oxygen present in the tissue, resulting in the production of free radicals and reactive oxygen derivatives. These highly reactive agents cause tissue damage, leading to necrosis or cell death. This property makes TFD a powerful tool in the treatment of various diseases, including cancer, infections and other pathological conditions. As research in this area has advanced, it has become clear that the effectiveness of TFD depends largely on the characteristics of the photosensitizer used. Therefore, there is a growing need to develop a variety of photosensitizers with specific characteristics to treat a wider range of diseases that can be targeted by phototherapy. In this literature review, we discuss the current challenges associated with the use of TFD, including the need for more effective and specific photosensitizers. We also summarize some of the most recent advances in the field of photosensitizers, highlighting their main applications in cancer treatment. TFD has emerged as a strong ally in the therapeutic field, offering a promising approach to treating cancer. TFD has emerged as a strong ally in the therapeutic field, offering a promising approach to treating a variety of health conditions. However, much remains to be done to optimize this technique and expand its use in clinical practice. With continued research and development in this area, TFD has the potential to revolutionize the field of medicine.
