Photodynamic Therapy (PDT)
Photodynamic Therapy (PDT) is an emerging method capable of treating a variety of cancers.
• PDT uses the combination of a photosensitizing agent (PS), light and oxygen to destroy the cancer without the significant side effects that occur with other treatment modalities.
• It can be used to treat recurrent cancer and be used in combination with other therapies.
• The compounds (photosensitizers) used in PDT also fluoresce. Therefore, these same agents can also be used for detection by fluorescence imaging. This enables fluorescence image-guided surgery and therapy.
Cancer Treatment Today and the Advantages of PDT
Major problem of cancer recurrence: inefficient treatment .
With Chemotherapy, toxicity is the main issue and benefits are limited.
Emerging Onco-Immunology Therapy: limited, unpredictable, and expensive
Surgery can result in loss of function, is expensive, and is sometimes incomplete.
PDT treatment can be used before or after surgery and/or chemotherapy.
