Patient risk stratification using Gleason score concordance and upgrading among men with prostate biopsy Gleason score 6 or 7.
PURPOSE To define the impact of discordant Gleason sum (GS) between prostate biopsy (Pbx) tissue and radical prostatectomy (RP) specimen among men initially diagnosed with Gleason 6 or 7 prostate adenocarcinoma. MATERIALS AND METHODS We evaluated patients diagnosed with GS 6 or 7 and treated primarily with RP. We defined the frequency of GS discordance between Pbx and RP pathology reports. We...
متن کاملFactors predicting prostatic biopsy Gleason sum under grading.
PURPOSE We determined clinical factors affecting the under grading of biopsy Gleason sum compared with prostatectomy pathology and developed a model predicting the probability of under grading. MATERIALS AND METHODS We analyzed a cohort of 1,701 patients treated for prostate cancer at our institution between 1988 and 2007 with complete biopsy and pathological data available. Patients with a b...
متن کاملProstate biopsy and radical prostatectomy Gleason score correlation in heterogenous tumors: proposal for a composite Gleason score.
When prostate biopsy cores are separately identified in multiple containers, current recommendations are to grade each specimen individually. For treatment algorithms, the highest Gleason score (HGS) is typically used as the overall score, even if a lower score predominates. This practice has the potential to misrepresent the overall cancer in the entire gland for some patients and place them i...
متن کاملAdenocarcinoma of the prostate with Gleason score 9-10 on core biopsy: correlation with findings at radical prostatectomy and prognosis.
PURPOSE There is a paucity of data on the prognosis after radical prostatectomy for Gleason score 9-10 disease on needle biopsy. To our knowledge we report the largest study to date to specifically analyze the correlation of Gleason score 9-10 on needle core biopsy with radical prostatectomy outcomes. MATERIALS AND METHODS We identified 259 men with Gleason score 9-10 on biopsy who underwent ...
متن کاملCorrelation between Gleason scores in needle biopsy and corresponding radical prostatectomy specimens. A twelve-year review.
Background: Presence of discordance between the Gleason score on needle biopsy and the score of radical prostatectomy specimen is common and universal. In this study, we determined the accuracy of Gleason grading of biopsies in predicting histological grading of radical prostatectomy specimens and the degree of overgrading and undergrading of prostatic adenocarcinoma i...
