内容記述
Prostate ductal adenocarcinoma is a rare variant of prostate cancer and considered to be more aggressive than the common acinar type of adenocarcinoma. The appropriate treatment guideline for prostate ductal adenocarcinoma has not been established. The aim of the present study was to examine the clinical characteristics and the effectiveness of treatment for prostate ductal adenocarcinoma. From 2005 to 2012, 41 patients were diagnosed to have prostate ductal adenocarcinoma in Kyoto University Hospital. The mean±SD age was 68.6±7.0 years, and the median (range) initial serum PSA level was 9.3 (3.7-217) ng/ml. Among 17 patients who underwent radical prostatectomy, 10 (58.8%) had pT3 disease and 5 (29.4%) had biochemical recurrence during median follow-up of 22.9 months. Out of 19 patients treated with definitive EBRT with endocrine therapy, 2 patients (10.5%) experienced biochemical recurrence with median follow-up of 37.3 months. Five patients were treated with endocrine therapy alone, and 2 (40.0%) of them died of prostate ductal adenocarcinoma. In conclusion, patients with prostate ductal adenocarcinoma were more likely diagnosed as locally advanced diseases than those with prostate acinar adenocarcinoma. However, for patients without metastasis, either surgery or EBRT with endocrine therapy is effective with goodprognosis.
