Popis: | Accurate prognostic parameters in prostate biopsies are needed to better counsel individual patients with prostate cancer. We evaluated the prognostic impact of morphologic and immunohistochemical parameters in preoperative prostate cancer biopsies. A consecutive series of prostate biopsies of 279 men (72% with clinical stage T1c and 23% with T2) who subsequently underwent radical prostatectomy was prospectively analysed for Gleason score, number and percentage of positive cores (NPC, PPC), total percentage of biopsy tissue with tumour (TPT), maximum tumour percentage per core (MTP), and expression of Ki67, Bcl-2 and p53. All biopsy features were significantly associated with at least one feature of the radical prostatectomy specimen. pT stage was independently predicted by PSA, seminal vesicle invasion by Ki67 LI, positive margins by PSA and MTP, large tumour diameter by PSA and PPC, and Gleason score by biopsy Gleason score, MTP, and Ki67 LI, respectively. Biopsy Gleason score, NPC (1 vs. >1), TPT ( |
