BACKGROUND: In the United States, disease-specific mortality from prostate cancer (PC) is highest among black men. While the introduction of widespread PSA testing has been associated with a downward stage migration, whether this trend continues in the late PSA era and for black men is unknown. The objective of our study was to evaluate current PC stage migration patterns in the United States by race. METHODS: The Surveillance, Epidemiology and End Results (SEER) registry was queried to obtain all cases of PC reported between 2000 and 2013...

BACKGROUND: The prognostic role of preoperative serum lipid levels in patients undergoing radical prostatectomy (RP) for clinically localized prostate cancer (PCa) is unclear. The aim of the present study was to investigate preoperative serum lipid levels in patients with clinically localized PCa undergoing RP and their association with clinicopathological features and oncological outcome. METHODS: Preoperative lipid levels (total cholesterol, LDL cholesterol, HDL cholesterol and triglycerides) and statin use from consecutive patients with clinically localized PCa undergoing RP in a tertiary referral center between 2008 and 2015 were recorded and patients were followed prospectively...

OBJECTIVE: Early-stage prostate cancer may be followed with active surveillance to avoid overtreatment. Our institution's active surveillance regimen uses annual MRI in place of serial biopsies, and biopsies are performed only when clinically necessary. The objective of our study was to report the multiparametric MRI characteristics of prostate cancer patients who discontinued active surveillance at our institution after repeat imaging revealed possible evidence of tumor upgrading. MATERIALS AND METHODS: The Department of Urology at Winthrop University Hospital prospectively maintains a database of prostate cancer patients who are monitored with active surveillance...

PURPOSE: To assess the efficacy of robotic-assisted laparoscopic sentinel lymph node (SLN) dissection (SLND) to select those patients with prostate cancer (PCa) who would benefit from additional pelvic external beam radiation therapy and long-term androgen deprivation therapy (ADT). METHODS AND MATERIALS: Radioisotope-guided SLND was performed in 224 clinically node-negative patients scheduled to undergo external beam radiation therapy. Patients with histologically positive SLNs (pN1) were also offered radiation therapy to the pelvic lymph nodes, combined with 3 years of ADT...

PURPOSE: We discuss our experience with the transition from CT-based to ultrasound-based HDR treatment planning for prostate cancer in a high-volume clinical setting. The details of switching from one afterloader vendor to another are also discussed. The four main stages of prostate HDR planning (image acquisition, target delineation, needle reconstruction, and plan optimization) are significantly modified when ultrasound imaging is used. METHODS: We employ a time-efficient needle reconstruction procedure that provides the necessary level of accuracy to rival the traditional CT-based method...

BACKGROUND: The urologist generally manages the treatment of men immediately following the diagnosis of prostate cancer (PCa). The role of other physician specialists in this setting is less clear. We investigated whether involvement of other physician specialty types immediately following diagnosis affects initiation of cancer-directed treatment. METHODS: This is a retrospective cohort study using linked cancer registry and claims data from 1999 to 2009, excluding stage I/II PCa...

BACKGROUND: Prostate-specific antigen (PSA) is widely used for prostate cancer screening, but low specificity results in high false positive rates of prostate biopsies. OBJECTIVE: To develop new risk assessment models to overcome the diagnostic limitation of PSA and reduce unnecessary prostate biopsies in North Chinese patients with 4-50 ng/mL PSA. METHODS: A total of 702 patients in seven hospitals with 4-10 and 10-50 ng/mL PSA, respectively, who had undergone transrectal ultrasound-guided prostate biopsies, were assessed...

Neuroendocrine differentiation of prostate cancer (PCa) is a relatively frequent event, generally understudied, that carries important prognostic information. It is most frequently observed during the advanced stages of disease, when PCa has lost its sensitivity to androgen deprivation therapy or to chemotherapy, moderate to diffuse bone metastatic spread dominates the imaging scenario and it is responsible for painful clinical symptomatology. However, evidences indicate that neuroendocrine differentiation is a progressive phenomenon that starts at the very early part of the pathogenesis of cancer transformation contributing to it...

The risk of recurrence for prostatic adenocarcinoma following prostatectomy, as detected by prostate specific antigen (PSA) or other modalities, is based primarily on Gleason score along with pathologic tumor stage and surgical margin status. Recent large multi-institutional data spanning the last decade have supported modification of risk of recurrence stratification based on Grade Groups: Grade Group 1 (3+3=6), Grade Group 2 (3+4=7), Grade Group 3 (4+3=7), Grade Group 4 (4+4=8), and Grade Group 5 (Gleason scores 9 and 10)...

OBJECTIVES: Prostate dose painting radiotherapy requires the accurate identification of dominant intra-prostatic lesions (DILs) to be used as boost volumes; these can be identified on multi-parametric MRI (mpMRI) or choline PET/CT. Planning scans are usually performed after 2-3 months of androgen deprivation therapy (ADT). We examine the effect of ADT on choline tracer uptake and boost volumes identified on choline PET/CT. METHODS: (18)F choline PET/CT were performed for dose painting radiotherapy planning in intermediate to high-risk prostate cancer patients...
