AIM This study was designed to evaluate the performance of shear-wave elastography as a diagnostic tool for prostate cancer in a larger cohort of patients than previously reported. PATIENTS AND METHODS Seventy-three patients with suspected prostate carcinoma were investigated by ultrasound elastography followed by directed biopsy. The elastographic and histological results for all biopsies we...

A new 30-gene signature has been described that separates prostate cancers of Gleason score ≤6 from those of Gleason score ≥8. It provides independent prognostic information for prostate cancers of intermediate risk (Gleason score of 7), which has the potential to stratify these patients into different risk groups.

Most tissue microarray studies have used a single 0.6-mm tissue core per donor tissue. It has been suggested that multiple cores per donor can increase the representativity of tissue microarray studies. To estimate the potential benefit of multiple cores, we analyzed Ki67 and p53 in triplet cores taken from three different areas of 3,261 prostate ...

Purpose. To identify pathological characteristics of prostate cancer according to patient age at diagnosis. Methods. A retrospective review of 2,929 men diagnosed with prostate cancer was performed. Pathological characteristics were compared across age groups: ≤55, 56-75, and >75 years. Results. The study cohort included 133 patients (4.5%), 2,033 patients (69.5%), and 763 patients (26.0%) in t...

The leading motivation behind wanting to call a 'malignant' prostate lesion 'benign' is the evidence of indolent prostate cancer that is not associated with a fatal outcome and in part makes therapeutic measures such as surgery and radiotherapy appear like overtreatment for some or possibly the majority of such patients. The present article reviews the definitions of 'precancerous lesion' and '...

Iron overload has been measured in 100 hepatic biopsies by three different methods: (i) biochemical assay of the liver iron concentration (LIC), (ii) histological grading (HISTO) and (iii) automated image analysis with a Leitz Texture Analysis System by estimating two parameters, (a) the total iron area (TIA) and (b) the first grey level step (FGLS) at which the iron is detected. Image analysis...

AIMS To evaluate concordance, upgrades and downgrades from biopsy to prostatectomy, and associated clincopathological parameters, using the recently proposed Gleason grade groups/International Society of Urologic Pathology (ISUP) grades. METHODS AND RESULTS We evaluated 2529 patients who underwent biopsy and prostatectomy in our institution from 2005 to 2014. A global grade group (GR)/Gleason...

BACKGROUND In this population-based study, we investigated the degree of concordance between Gleason scores obtained from prostate biopsies and those obtained from prostatectomy specimens, as well as the determinants of biopsy understaging. METHODS We considered for this study all 371 prostate cancer patients recorded at the Geneva Cancer Registry diagnosed from 2004 to 2006 who underwent a r...

PURPOSE The PSA recurrence develops in 27 to 53% within ten years after radical prostatectomy (RP). We investigated the factors (disease grade and stage or the surgeon's expertise,) more likely to influence biochemical recurrence in men post-radical prostatectomy for organ-confined prostate cancer by different surgeons in the same institution. MATERIALS AND METHODS A total of 510 patients tha...

OBJECTIVE To more clearly elucidate the association between prostate volume and Gleason score (GS) upgrading. PATIENT AND METHODS We reviewed 451 patients with prostate cancer with a GS of 6 on biopsy, who underwent radical prostatectomy without neoadjuvant treatment. As a preoperative variable, we assessed the independent effect of prostate volume on GS upgrading. To evaluate the association...
