Photodynamic therapy (PDT) utilizes photosensitizers and laser light for targeted cancer treatment. This review covers PDT's mechanisms, photosensitizers, and clinical applications for effective tumor eradication.

Area of Science:

  • Oncology
  • Biochemistry
  • Photomedicine

Background:

  • Photodynamic therapy (PDT) is an emerging local treatment for malignant tumors.
  • PDT relies on the selective accumulation of photosensitizers in cancerous tissues.
  • Subsequent laser irradiation triggers therapeutic effects.

Purpose of the Study:

  • To review photosensitizers, photochemistry, and lasers used in PDT.
  • To discuss subcellular targets and side effects of PDT.
  • To present in vitro/in vivo mechanisms and clinical applications of PDT.

Main Methods:

  • Review of scientific literature on photodynamic therapy.
  • Analysis of biological, photochemical, and photophysical processes in PDT.
  • Compilation of data on photosensitizer absorption, retention, and laser irradiation.

Main Results:

  • PDT involves photosensitizer absorption, tumor retention, and laser activation.
  • Key components include photosensitizers, lasers, and understanding of photochemical reactions.
  • The report details various aspects from molecular mechanisms to clinical outcomes.

Conclusions:

  • Photodynamic therapy is a versatile modality for cancer treatment.
  • Further research enhances understanding of PDT mechanisms and applications.
  • PDT offers a promising approach for localized tumor management.
