Photodynamic Therapy (PDT) in Lung Cancer

"Photodynamic Procedure:~Photofrin II will be injected at a dosage of 2 mm/Kg intravenously. Laser treatment will take place 40-50 hours later. An argon-dye or an excimer-dye laser tuned to 620-630 nm will be used.~It is anticipated that a microlens fiber will be used in almost all cases, but a cylinder-diffusing fiber can be used to treat lesions in segmental bronchi if needed.~Argon-dye laser: Power settings 200 milliwatt (mW) microlens and 400 mW for cylinder Excimer laser: 4 milliJoules (mJoules)/pulse at 30 hertz for the microlens~Energy density:~Argon-dye laser: 200-300 Joules/cm\^2 Excimer-dye laser: 100-200 Joules/cm\^2"
