OBJECTIVE To use the national Surveillance, Epidemiology, and End Results (SEER) cancer registry to describe the natural history, national incidence and treatment patterns for ductal prostate cancer (PCa) over the last 20 years, as the available literature on ductal PCa is limited to small case series because of few patient numbers. PATIENTS AND METHODS From the SEER registry, 693 men with ductal PCa were identifi ed from 1970. The demographics, clinical features and cause of death data were collected from men with ductal and acinar histological types. RESULTS The incidence of ductal PCa has increased over each decade, but the overall percentage of ductal relative to acinar PCa has remained stable. Men with ductal PCa were more likely to present with advanced disease (30% T3 with ductal PCa, compared with 7% with acinar PCa). Men with ductal PCa underwent similar rates of radical surgery, lower rates of radiotherapy but a higher frequency of outlet (transurethral resection) procedures. Men with ductal PCa had a signifi cantly greater rate of death from PCa (12% vs 4%) than men with acinar PCa. Comparing PCa- specifi c mortality, men with ductal PCa had similar rates of death to men with Gleason 4 + 4 grade acinar PCa. CONCLUSIONS Despite a stable incidence, ductal PCa remains an aggressive PCa usually presenting with advanced clinical stage and resulting in a high rate of PCa- specifi c mortality similar to Gleason 4 + 4 acinar PCa. Patients would probably benefi t from combined modalities including radical surgery, radiotherapy and palliative outlet procedures.
