Laypersons versus experienced surgeons in assessing simulated robot-assisted radical prostatectomy.

Background: Feedback is important for surgical trainees but it can be biased and time-consuming. We examined crowd-sourced assessment as an alternative to experienced surgeons' assessment of robot-assisted radical prostatectomy (RARP).

Methods: We used video recordings (n = 45) of three RARP modules on the RobotiX, Simbionix simulator from a previous study in a blinded comparative assessment study.

Medical Students Cannot Assess Robotic Surgeons Performing Radical Prostatectomy.

Introduction: Medical students have previously been shown to be just as effective for video rating as experts. We want to compare medical students to experienced surgeons as video assessors of simulated robot-assisted radical prostatectomy (RARP) performance.

Materials And Methods: Video recordings of three RARP modules on the RobotiX (formerly Simbionix) simulator from a previous study were used.

Introduction of salvage prostatectomy in Denmark: the initial experience.

Objective: To introduce salvage prostatectomy in Denmark. Prior to this, no national curative treatment for recurrent prostate cancer following radiation therapy existed in Denmark. This pilot study represent our initial experiences and the feasibility of performing salvage robot-assisted radical prostatectomy for true local, high-risk recurrence after initial therapy with external beam radiation for high-risk prostate cancer.

Artificial intelligence-based detection of lymph node metastases by PET/CT predicts prostate cancer-specific survival.

Introduction: Lymph node metastases are a key prognostic factor in prostate cancer (PCa), but detecting lymph node lesions from PET/CT images is a subjective process resulting in inter-reader variability. Artificial intelligence (AI)-based methods can provide an objective image analysis. We aimed at developing and validating an AI-based tool for detection of lymph node lesions.

A prospective study of a urine and plasma biomarker test for the prediction of gleason ≥3 + 4 prostate cancer in a mixed cohort.

Definitive diagnosis of prostate cancer is based on biopsies, a procedure associated with side-effects. The use of biomarkers in blood and urine could potentially help clinicians select patients for whom biopsies are needed. The aim of the study was to test a new urine and plasma biomarker test in detecting medium and high grade prostate cancer.

F-Fluoromethylcholine-positron emission tomography/computed tomography for diagnosing bone and lymph node metastases in patients with intermediate- or high-risk prostate cancer.

Background: The use of molecular imaging in staging of prostate cancer (PC) is debated. In patients with newly diagnosed PC we investigated the diagnostic value of F-flouromethylcholine positron emission tomography/computed tomography (F-FCH-PET/CT) for the detection of bone and lymph node metastases compared to whole-body bone scintigraphy (WBS) with technetium-99-methylene diphosphonate (Tc-MDP) and results of extended pelvic lymph node dissection, respectively.

Materials And Methods: Between January 2013 and April 2016, 143 patients, aged 49-83, mean 69, years with newly diagnosed PC and disease characteristics necessitating WBS underwent both WBS and F-FCH-PET/CT using magnetic resonance imaging as standard.

Does therapy of the primary tumor matter in oligometastatic prostate cancer? A prospective 10-year follow-up study.

The effect of curative treatment for oligometastatic prostate cancer patients is unsolved, both with regard to morbidity and mortality. With this study, we provide some of the first long-term follow-up data on progression and mortality in oligometastatic prostate cancer patients after curative treatment of their primary tumor. A cohort of 210 patients with diagnosed prostate cancer was established between 2008 and 2010.

A prospective study on dual time F-FDG-PET/CT in high-risk prostate cancer patients.

Objective: This proof of concept study investigated whether dual time point FDG-PET/CT with image acquisition after 1 and 3 h could be useful in preoperative staging of patients undergoing robot-assisted radical prostatectomy and extended pelvic lymph node dissection for high-risk prostate cancer.

Results: Twenty patients with high-risk prostate cancer underwent dual time point FDG-PET/CT before undergoing surgery. Histologically confirmed lymph node metastases were found in 9/20 (45%).

[Metastasis in testis from prostate cancer].

We present a case of an 89-year-old male diagnosed with a prostatic adenocarcinoma. He developed a metastasis to his left testis and was treated with bilateral orchiectomy. Histology showed a ductal adenocarcinoma with positive immunohistochemical markers for PSA and p501.
