There are several reasons why PIN is the most likely prostate cancer precursor. [3] PIN is more common in men with prostate cancer. High grade PIN can be found in 85 to 100% of radical prostatectomy specimens, [4] nearby or even in connection with prostate cancer. It tends to occur in the peripheral zone of the prostate.

34βE12, often written as 34betaE12 and also known as CK34βE12 and keratin 903 (CK903), is an antibody specific for high molecular weight cytokeratins 1, 5, 10 and 14. [1] [2]It is sometimes, less precisely, referred to as high-molecular weight keratin (HMWK) and high-molecular weight cytokeratin (HMWCK).
