title: Prostatic adenocarcinoma of ductal origin.
abstract: Adenocarcinomas that arise from primary or secondary prostatic ducts have distinctive histopathologic features. The age of patients, symptoms, findings on digital rectal examination and determinations of serum acid and alkaline phosphatase are similar to those of patients with acinic carcinomas. Carcinomas of secondary ducts may be less responsive to endocrine manipulation and of greater malignancy than carcinomas of primary ducts. The course and survival of patients with ductal carcinomas treated conservatively are poor.
