Mechanism of Action

Day 1

You will be given an injection of the photoacive drug Photofrin.

Day 1

Day 3

40 to 50 hours after the Photfrin injection, light from a laser will activate the drug within the cancer cells, which will destroy them. The type of laser used in PDT is non-thermal, meaning no heat is involved, so it will not burn.

Day 3

The physician will direct the laser light through a fiberoptic guide that is passed through an endoscope (a thin tube) that is placed down your throat. The application of light takes anywhere from 5 to 30 minutes depending on the tumor amount your doctor wants to treat. For many patients the entire procedure takes under one hour.
