Reduction of lower urinary tract symptoms in prostate cancer patients treated with robot assisted laparoscopic prostatectomy.

Problem: The aim of this study was to evaluate the change in LUTS in patients treated with RALP and to assess factors that may predict an improvement of LUTS.

Materials And Method: In our institutional prospective research registry, 1935 patients operated in the period between 2009 and 2021 with complete baseline- and 12-month EPIC-26 questionnaire were eligible for the study. Also SF-12 data estimating general quality of life (QoL) were analyzed.

Low Blood Levels of LRG1 Before Radical Prostatectomy Identify Patients with High Risk of Progression to Castration-resistant Prostate Cancer.

Background: After radical prostatectomy (RP), depending on stage, up to 40% of patients with prostate cancer (PCa) will experience biochemical failure (BF). Despite salvage therapy, approximately one-third of these patients will need permanent hormone therapy (pHT) and are at risk of progression to castration-resistant PCa (CRPC). Prognostic markers herald the need for neoadjuvant, adjuvant, or multimodal treatment.

Robotic salvage pelvic lymph node dissection for locoregional recurrence after radical prostatectomy: a single institution experience.

Objectives: To assess treatment response (PSA < 0.2 ng/ml), need for additional therapy and complication rate after robot assisted salvage pelvic lymph node dissection (sPLND).

Material And Methods: Analysis of outcomes data from radical prostatectomy (RP) patients consecutively operated with robot assisted sPLND due to biochemical recurrence and positron-emission tomography (PET)/computed tomography (CT)-detected nodal recurrence of pelvic lymph nodes.

Improved patient-reported functional outcomes after nerve-sparing radical prostatectomy by using NeuroSAFE technique.

To explore whether prostatectomized men report improved post-operative erectile function and urinary control dependent on the application of intra-operative frozen section examination (NeuroSAFE) during nerve-sparing radical prostatectomies (NS-RPs). Pre- and post-RP responses to the sexual domain and the urinary incontinence subscale of EPIC-26 were analyzed in 95 and 312 men from a NeuroSAFEGroup (Martini-Klinik, Hamburg, Germany) and a Non-NeuroSAFE Group (Oslo University Hospital, Norway), respectively, undergoing NS-RPs for ≤ cT2 prostate cancer. All patients had intra-prostatic tumors as evaluated by Digital Rectal Examination.

Switching from laparoscopic radical prostatectomy to robot assisted laparoscopic prostatectomy: comparing oncological outcomes and complications.

Objectives: To compare oncological outcomes and complication rates based on the Clavien classification between laparoscopic radical prostatectomies (LRP) and robot-assisted laparoscopic radical prostatectomies (RALP).

Material And Methods: In a prospective quality registry clinical data were consecutively entered for 544 LRP and 1081 RALP patients operated from 2003 to the end of 2012. Complications within 90 days postoperatively were assessed according to the Clavien classification and compared between LRP and RALP patients.

Preclinical Amyloid-β and Axonal Degeneration Pathology in Delirium.

Background: The clinical relevance of brain β-amyloidosis in older adults without dementia is not established. As delirium and dementia are strongly related, studies on patients with delirium may give pathophysiological clues.

Objective: To determine whether the Alzheimer's disease (AD) cerebrospinal fluid (CSF) biomarkers amyloid-β 1-42 (Aβ42), total tau (T-tau), and phosphorylated tau (P-tau) are associated with delirium in hip fracture patients with and without dementia.

Tomato-based randomized controlled trial in prostate cancer patients: Effect on PSA.

Background & Aims: The effect of lycopene-containing foods in prostate cancer development remains undetermined. We tested whether a lycopene-rich tomato intervention could reduce the levels of prostate specific antigen (PSA) in prostate cancer patients.

Methods: Prior to their curative treatment, 79 patients with prostate cancer were randomized to a nutritional intervention with either 1) tomato products containing 30 mg lycopene per day; 2) tomato products plus selenium, omega-3 fatty acids, soy isoflavones, grape/pomegranate juice, and green/black tea (tomato-plus); or 3) control diet for 3 weeks.

PBX3 is a putative biomarker of aggressive prostate cancer.

There is a great need to identify new and better prognostic and predictive biomarkers to stratify prostate cancer patients for optimal treatment. The aims of this study were to characterize the expression profile of pre-B cell leukemia homeobox (PBX) transcription factors in prostate cancer with an emphasis on investigating whether PBX3 harbours any prognostic value. The expression profile of PBX3 and PBX1 in prostate tissue was determined by immunohistochemical and immunoblot analysis.

A Randomized Controlled Trial To Assess and Compare the Outcomes of Two-core Prostate Biopsy Guided by Fused Magnetic Resonance and Transrectal Ultrasound Images and Traditional 12-core Systematic Biopsy.

Background: Prostate biopsy guided by computer-assisted fusion of magnetic resonance imaging (MRI) and transrectal ultrasound (TRUS) images (MRI group) has not yet been compared with 12-core random biopsy (RB; control group) in a randomized controlled trial (RCT).

Objective: To compare the rate of detection of clinically significant prostate cancer (csPCa) between the two groups.

Design, Setting, And Participants: This RCT included 175 biopsy-naïve patients with suspicion for prostate cancer, randomized to an MRI group (n=86) and a control group (n=89) between September 2011 and June 2013.

Does preoperative magnetic resonance imaging reduce the rate of positive surgical margins at radical prostatectomy in a randomised clinical trial?

Background: Magnetic resonance imaging (MRI) has the potential to help the surgeon tailor radical prostatectomy (RP) more accurately according to the location and extent of the tumour and thereby reduce the rate of positive surgical margins (PSMs).

Objective: To evaluate the benefit of performing MRI prior to RP.

Design, Setting, And Participants: This single-institution randomised trial included 438 patients between December 2009 and June 2012 who were scheduled for robot-assisted laparoscopic prostatectomy.

Preoperative magnetic resonance imaging for detecting uni- and bilateral extraprostatic disease in patients with prostate cancer.

Objective: The objective of the study was to evaluate the diagnostic accuracy of preoperative magnetic resonance imaging (MRI) for detecting uni- and bilateral extraprostatic disease (T3) in patients with prostate cancer (PCa).

Materials And Methods: This prospective study included 199 patients with biopsy-proven PCa who underwent MRI prior to radical prostatectomy from December 2009 to July 2012. Extraprostatic extension and seminal vesicle invasion represented T3 disease, and was classified as uni- (right or left) or bilateral.

Does a surgeon's annual radical prostatectomy volume predict the risk of positive surgical margins and urinary incontinence at one-year follow-up? Findings from a prospective national study.

Objective: This study aimed to assess the prevalence of positive surgical margins (PSM) and urinary incontinence (UI) in relation to surgeons' annual radical prostatectomy (RP) volume.

Material And Methods: This national study prospectively assessed 521 preoperatively continent patients with prostate cancer (PCa), scheduled for RP by surgeons with high (>50), medium (20-50) or low annual volume (<20) at 14 urological departments in Norway. Patients responded to UI questions from the Expanded Composite prostate cancer index (EPIC-50) before and 1 year after RP.

Five-year progression-free survival in 577 patients operated on with laparoscopic radical prostatectomy for localized prostate cancer.

Objective: Laparoscopic radical prostatectomy (LRP) was introduced in the Department of Urology, Oslo University Hospital, in 2002. The aim of this study was to report mid-term oncology results and survival data.

Material And Methods: From February 2002 to November 2007, 582 consecutive patients with localized prostate cancer underwent LRP.
