Popis: Background Photodynamic therapy is a less invasive therapeutic procedure for carcinomas. The goal of this study was to evaluate the utility of Photofrin (porfimer sodium)-mediated photodynamic therapy in patients with head and neck squamous cell carcinoma. Methods Forty-two head and neck squamous cell carcinoma patients who underwent Photofrin-mediated photodynamic therapy were treated by intraoperative light activation at 630 nm via a fiber optic microlens, 48 h after injection. We evaluated the impact of age, sex, tumor stage, primary site, light dose, and cancer history on overall survival using a Cox proportional hazards model. Information on the survival status of patients was obtained after a mean follow-up period of 51 months (range, 6–180 months). Results The 5-year overall survival for all patients was 57.8 % (95 % confidence interval of the survival rate: 39.8 %–72.1 %). The complete response rate was 69.0 %, and the efficacy (complete response + partial response) was 97.6 %. Earlier tumor stage was associated with increased survival (p = 0.012). Diseases of the respiratory tract also showed significant association with survival as compared to those of the alimentary tract (p = 0.01). Conclusions Photofrin-mediated photodynamic therapy is useful for treating head and neck squamous cell carcinomas, and provides an improved quality of life in patients with recurrent or residual disease.
