Intraductal carcinoma of the prostate in an Irish prostate cancer patient cohort-an aggressive pathology and a strong familial link.

Background: The prevalence of intraductal carcinoma of the prostate (IDC-P) is poorly studied in the Irish population. This study investigated the incidence and clinicopathologic characteristics of IDC-P in an Irish prostate cancer (PCa) patient cohort. The study also discusses the rationale for genetic counseling and screening in Irish patients with familial risk factors for IDC-P.
