BACKGROUND: Prostate-specific antigen (PSA) screening more frequently detects early stage prostate cancer (PC). However, adverse pathologic features (APFs) after radical prostatectomy (RP) in low-risk PC occur. Previous related studies had utilized outdated staging criteria or small sample cohorts. In this study, we analyzed predictors of APFs after RP in low-risk PC using classification under the current criteria. MATERIALS AND METHODS: We retrospectively reviewed medical records of 546 low-risk PC patients who had undergone RP...

BACKGROUND: The accuracy of18 F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) to stage prostate cancer (PCa) is limited. However, Gleason 8-10 PCa and more aggressive metastatic PCa have been shown to exhibit a higher glycolytic activity. OBJECTIVE: To evaluate the potential of intraprostatic FDG uptake to prognose Gleason 8-10 PCa patients prior to prostatectomy, based on tumour intrinsic biology. DESIGN, SETTING, AND PARTICIPANTS: FDG-PET/CT and a bone scan were performed as a staging procedure prior to prostatectomy in 148 consecutive patients diagnosed with PCa with a Gleason sum of ≥8 at biopsy...

Background: After radical prostatectomy (RP) radiotherapy (RT) plays a role, both as adjuvant or salvage treatment. If negative features are present such as extracapsular extension, seminal vesicle invasion, lymph invasion, and positive surgical margins, RT after RP reduces the risk of recurrence, although it is associated with an increased risk of acute and late toxicities. An intensified RT delivered in a shortened time could improve clinical outcome and be safely combined with hormonal therapy (HT)...

INTRODUCTION: Prostate cancer (PC) most of the time presents with an indolent course. Thus, delays in treatment due to any causes might not affect long-term survival and may not affect cancer cure rates. PURPOSE: In this study, we evaluated the effect of delay-time between PC diagnosis and radical prostatectomy regarding oncological outcomes: Gleason score upgrade on surgical specimen, pathologic extracapsular extension (ECE) on surgical specimen, and postoperative biochemical recurrence (BCR) on follow-up...
