title: Penile intraepithelial neoplasia: results of photodynamic therapy.
abstract: Failure of response to treatment or recurrent disease is often noted in patients with penile intraepithelial neoplasia. Photodynamic therapy has recently been added to the list of treatment modalities used for this diagnosis. Our primary objective was to study the results of photodynamic therapy in the treatment of penile intraepithelial neoplasia in men over the age of 40 years. Ten patients aged 42-82 years with histopathologically confirmed lesions were studied. Lesions initially responded to photo-dynamic therapy in 7 out of 10 patients. Four of these patients presented no recurrences during a mean follow-up of 35 months, and were completely cleared after 2-8 treatments (mean 4.5 treatments). Three patients presented recurrences after treatment. No patient developed invasive penile cancer (mean follow-up 46.5 months). Photodynamic therapy is an alternative in the treatment of penile intraepithelial neoplasia, although prospective randomized trials are required to provide therapeutic guidelines.
