Abstract
Photodynamic therapy was used to treat 111 lesions in 27 cases with squamous and basal cell carcinoma. There were 82 squamous cell carcinomas and 29 basal cell carcinomas. Photofrin was administered intravenously at either 1.0 mg/kg or 0.75 mg/kg. An argon/dye laser was used to deliver 630 nm light to the lesion superficially at either 215 J/cm2 or 240 J/cm2. In some cases the laser light was delivered both superficially and interstitially. The laser light was delivered two to four days after the Photofrin injection. There were 105 complete responses and 5 partial responses. One patient was lost to follow-up. Among partial responses were basal cell carcinoma on the tip of the nose and morphea basal cell carcinoma of the left cheek. Another partial response occurred in a basal cell carcinoma patient where insufficient margins were treated due to the proximity to the eye. When 0.75 mg/kg drug dose was used, the selectivity of tumor necrosis was improved. Decreased period of skin photosensitivity was documented in some cases.
