Clinical Pearls:
- In classic photodynamic therapy, a photosensitizer is injected into a patient or is topically applied. The photosensitizer is selectively taken up by cancer cells.
- A light of a specific wavelength is then applied to the site. This kills the cancer but reduces the damage to the surrounding tissue.
- If the tumor is too deep, the light will not be able to reach it.
- This study will evaluate a new approach where the light delivery device is placed directly into the tumor.
