Summary
Photodynamic therapy (PDT) effectively treats superficial skin tumors and deep prostate cancers. This review highlights optical diagnostics, dosimetry, and light dose delivery for optimal oncological PDT outcomes.
Area of Science:
- Oncology
- Photomedicine
- Biomedical Engineering
Background:
- Photodynamic therapy (PDT) is a promising oncological treatment modality.
- PDT utilizes light, a photosensitizer, and oxygen to generate cytotoxic effects.
- Superficial and interstitial applications present distinct challenges in PDT delivery.
Purpose of the Study:
- To review photodynamic therapy (PDT) applications in oncology, focusing on skin tumors and prostate cancer.
- To illustrate the challenges and advancements in superficial and interstitial PDT.
- To highlight the integration of optical diagnostics and dosimetry for effective light dose delivery.
Main Methods:
- Review of over 20 years of experience with PDT at Lund University.
- Examination of superficial PDT for skin lesions and interstitial PDT for prostate cancer.
- Discussion of interactive multiple-fiber interstitial procedures for precise light delivery.
Main Results:
- PDT demonstrates efficacy in treating both superficial and deep-lying tumors.
- Optical diagnostics and dosimetry are crucial for optimizing therapeutic light dose.
- An interactive interstitial procedure allows real-time adjustments for effective treatment.
Conclusions:
- PDT is a versatile oncological treatment with distinct approaches for superficial and interstitial applications.
- Accurate dosimetry and real-time monitoring are key to successful PDT outcomes.
- Advancements in interstitial PDT enhance treatment precision and efficacy for deep-seated tumors.
