While PIN was initially divided into high- and low-grade lesions, low-grade PIN is not a precursor to carcinoma and therefore receives little attention. 2009 Dec;104(11):1554-6. doi: 10.1111/j.1464-410X.2009.08923.x. endobj It is typically discovered in prostate biopsies taken to rule-out There are several reasons why PIN is the most likely prostate cancer precursor.The risk for men with high grade PIN of being diagnosed with prostate cancer after repeat biopsy has decreased since the introduction of biopsies at more than six locations (traditional sextant biopsies).Several architectural variants of PIN have been described, and many cases have multiple patterns. Despite large differences in serum lycopene following intervention, no treatment effects were apparent on either the serum or benign tissue endpoints. 0000003554 00000 n <> 0000014104 00000 n HGPIN in isolation is asymptomatic. In early stages, prostate cancer generally causes no symptoms and is typically detected by screening.
