Progression of Peyronie's Disease during Tamoxifen Treatment / 대한남성과학회지

ABSTRACT

PURPOSE: Medical treatment of Peyronie's disease with tamoxifen has been initially proposed as acting upon the early phase of the disease. As recent reports show no significant benefit of tamoxifen, we review the long term results of tamoxifen treatment of Peyronie's disease. MATERIALS AND METHODS: Time to progression during tamoxifen treatment of patients showing acute disease and chronic disease was compared. The acute phase was identified by pain during erection. Progression was defined as enlargement of plaque size or appearance of calcification. RESULTS: The average treatment duration was 15.9+/-13.8 months (range 3 to 48 months). The median time to progression was 7 months for acute patients and 20 months for chronic patients. Eighty percent of patients in the acute phase showed relief of pain; however, overall progression was 72.1% (78.0% for acute, 66.7% for chronic). Patient history, comorbidities, serum testosterone or initial plaque characteristics, and severity of curvature were not predictive of disease progression. CONCLUSIONS: Tamoxifen showed no significant benefit in slowing the progression of Peyronie's disease in the acute phase over the chronic phase. Peyronie's disease continued to progress, though at a dampened rate for patient's in the chronic phase.
