Levels of prostatic intraepithelial neoplasia (PIN) could allow for a more precise prognosis for prostate cancer, suggests study published in Cancer Epidemiology, Biomarkers & Prevention.

The researchers evaluated men with localized prostate cancer diagnosed following a surgical procedure to treat benign prostatic hyperplasia. Of these men, 228 died of prostate cancer and 387 were diagnosed with prostate cancer, but were still alive after 10 years. Those with PIN were 89 percent more likely to die of prostate cancer.

Even after accounting for age, Gleason score, year of diagnosis, inflammation and type of focal atrophy present, PIN still managed to independently predict the lethality of a given tumor. There was also a suggestion that the degree of chronic inflammation adjacent to the tumor could predict lethal outcome.

"Identifying features surrounding the tumor that can predict prognosis, such as the presence of PIN or inflammation, can improve our understanding of the biology of aggressive prostate cancer and help to guide clinical decision-making," said Rider.

The study was funded by the United States Department of Defense, the National Institutes of Health, the Prostate Cancer Foundation and the Swedish Cancer Society.
