Definition

High-grade prostatic intraepithelial neoplasia (HGPIN) is a neoplastic proliferation of secretory cells within preexisting ducts and acini, with cytological changes resembling those seen in cancer. HGPIN is the most likely precursor of prostatic adenocarcinoma, according to virtually all available evidence.

Clinical Features

  • Incidence

    The mean incidence of HGPIN in prostatic needle biopsies is about 5%.

  • Age

    Patients aged 50–60 years.

  • Sex

    Male.

  • Site

    The most commonly location is in the peripheral zone of the prostate.

  • Treatment

    Treatment is not indicated. Prophylactic RP or radiation is not an acceptable treatment. Patients with isolated HGPIN in needle biopsy may be considered for enrolment into clinical trials with chemoprevention agents. Men with a single core positive for HGPIN do not require routine repeat biopsy. In multifocal HGPIN, follow-up monitoring could include serum and urine tests or imaging.

  • Outcome

    The...
