Photodynamic therapy (PDT) utilizing Photofrin II is proving to be an effective modality in the treatment of early stage lung cancer. However, wider clinical application of Photofrin II as a photosensitizer for various cancers is hampered by the potentially serious and prolonged skin photosensitivity. To prevent these side effects and reduce the inpatient period, we recently tried to give reduced doses of Photofrin II by bronchial artery infusion (BAI). Six patients with endoscopically evaluated early stage carcinoma of the lung were given 0.7 mg/kg of Photofrin II by BAI 48 hours before PDT. Complete remission was obtained in all 6 cases, and there was no evidence of skin photosensitivity when exposed to outside light under careful surveillance at one week after PDT. |
