Superficial radiation therapy in peyronie's disease: An effective and well-tolerated therapy.

PURPOSE: This study aimed to assess the safety, efficacy, and patient satisfaction of superficial radiation therapy in the treatment of Peyronie's disease (PD) in a retrospective analysis.

METHODS AND MATERIALS: We performed a retrospective analysis of 83 patients who underwent radiation therapy between 1999 and 2008 with 8 fractions of 4 Gy over a period of 6 months. With a mean follow-up time of 52 months, patients responded to a comprehensive questionnaire that covered patient characteristics, disease duration before radiation therapy, course of disease, treatment response, side effects, and patient satisfaction.

RESULTS

After a mean follow-up time of 52 months, 78% of the treated patients reported that PD progression had stopped. Furthermore 47% of patients had a symptom regression. Only 7% of patients reported PD progression. The penile curvature was improved in 49% of patients, and plaque induration could be reduced in 42% of patients. Moreover, 71% of patients reported substantial pain relief, as measured by a visual analogue scale (1 = not satisfied; 10 = very satisfied). Treatment satisfaction was rated with a median of 8 in a visual analogue scale out of 10. Side effects included transient erythema in 38.6% of patients and 9.6% reported of transient or chronic dryness. No severe side effects were observed.

CONCLUSIONS

Radiation therapy for PD in the disease's early stages proved to be a safe and well-tolerated method with good results in pain relief, especially in patients aged <62 years. No serious adverse events or malign transformations are expected using doses up to 32 Gy.
