PURPOSE We evaluated oncologic outcomes following radical prostatectomy (RP) in patients with a Gleason score (GS) of 7 with tertiary Gleason pattern 5 (TGP5). MATERIALS AND METHODS We retrospectively reviewed the medical records of 310 patients who underwent RP from 2005 to 2010. Twenty-four patients who received neoadjuvant or adjuvant antiandrogen deprivation or radiation therapy were excl...

OBJECTIVES To identify post-prostatectomy prognostic factors for biochemical recurrence (BR). METHODS We retrospectively analyze a series of patients with clinically localized prostate cancer who were treated with radical prostatectomy (RP)as monotherapy between 1996 and 2007, pN0-pNx, with a minimum of 12 months of follow-up. BR is considered to be persistence or elevation in PSA after RP gr...

The Prostate Health Index (PHI) has been used increasingly in the context of prostate cancer (PCa) diagnostics since 2010. Previous studies have shown an association between PHI and a tumor volume of >0.5 cm³. The aim of this study was to investigate the correlation between PHI and tumor volume as well as the Gleason score. A total of 196 selected patients with prostate cancer treated with radi...

BACKGROUND Discordance between the Gleason scores of prostate needle biopsies and radical prostatectomy specimens has been reported by several investigators. We conducted this study to determine if increasing the number of prostate needle biopsies in patients with prostate cancer improves the accuracy of Gleason scores in the Taiwanese population. METHODS Between March 2000 and September 2009...

OBJECTIVE To evaluate the sensitivity of multiparametric magnetic resonance imaging (mp-MRI) for detecting prostate cancer foci, including the largest (index) lesions. PATIENTS AND METHODS In all, 115 patients with biopsy confirmed prostate cancer underwent mp-MRI before radical prostatectomy. A single expert radiologist recorded all prostate cancer foci including the index lesion 'blinded' t...

OBJECTIVE To test the expandability of active surveillance (AS) to Gleason score 3+4 cancers by assessing the unfavorable disease risk in a large multi-institutional cohort. MATERIALS AND METHODS We performed a retrospective analysis including 2,323 patients with localized Gleason score 3+4 prostate cancer who underwent a radical prostatectomy between 2005 and 2013 from 6 academic centers. We...

OBJECTIVE To evaluate the impact of the extent of extraprostatic extension (EPE) on biochemical recurrence-free survival (BCRFS) after radical prostatectomy (RP). MATERIALS AND METHODS We queried our RP database from 2004 to 2013. Extent of EPE on RP was divided into 3 groups: no EPE, focal EPE (F-EPE; a few extraprostatic cancer glands on 1-2 slides), and nonfocal EPE (NF-EPE). Multivariate ...

BACKGROUND PCDH8 is a newly-discovered suppressor gene that is frequently inactivated by aberrant methylation in several human cancers, including prostate cancer. The identification of PCDH8 methylation can be used as a potential predictive biomarker. Prostate cancer patients with high Gleason score are considered as being at high risk for tumor recurrence and progression, and adjuvant therapy ...

Systemic inflammatory status has been reported to impact survival of prostate cancer (PCa) patients; however, evidence is lacking on whether the inflammatory potential of diet can influence prognosis of PCa patients. To investigate the association between a dietary inflammatory index (DII) and PCa survival, we conducted a retrospective cohort study including 726 men with PCa originally enrolled...

BACKGROUND Recommendations for active surveillance versus immediate treatment for low risk prostate cancer are based on biopsy and clinical data, assuming that a low volume of well-differentiated carcinoma will be associated with a low progression risk. However, the accuracy of clinical prediction of minimal prostate cancer (MPC) is unclear. OBJECTIVES To define preoperative predictors for MP...
