The Gleason grading system is among the most important prognostic factors in patients with prostate cancer. From the 2005 to the 2014 consensus conferences, organized by the International Society of Urological Pathology, the morphologic criteria for the identification of the Gleason patterns were redefined, thus resulting in the shrinkage of the Gleason pattern 3. This led to the expansion of the Gleason pattern 4. The newly proposed grade group system reduces the Gleason scores of prostate cancer to the lowest number, each associated with a unique behavior from the prognostic point of view...

INTRODUCTION: Hepatocellular carcinoma is a lethal disease worldwide and therefore the establishment of novel diagnostic biomarkers is imperative. In this study, it was hypothesized that an abnormal expression of the lysosomal-associated protein transmembrane 4 beta ( LAPTM4B) gene is crucial in the pathogenesis of hepatitis C virus-mediated hepatocellular carcinoma; hence we investigated the expression profile of LAPTM4B in hepatitis C virus-induced hepatocellular carcinoma. METHODS: A group of 189 consecutive patients (hepatitis C virus-related hepatocellular carcinoma as tumor cases; n=93, hepatitis C virus-related cirrhotics as disease controls; n=96) opting for living donor liver transplantation as a therapeutic surgical regimen were recruited with informed consent...

INTRODUCTION: Total PSA (tPSA) and free PSA (fPSA) are the most commonly used biomarkers for early detection of prostate cancer. Despite standardization efforts, many available PSA assays may still produce discordant results. In the present study, we compared four PSA assays calibrated to the WHO standards 96/670 and 96/668 for tPSA and fPSA, respectively. METHODS: Within the scope of the Prostate Cancer Early Detection Study Based on a ''Baseline'' PSA Value in Young Men (PROBASE), we tested tPSA and fPSA in serum samples from 50 patients in the four different PROBASE sites using four WHO-calibrated assays from Roche (Elecsys, Cobas), Beckman-Coulter (Access-II) and Siemens (ADVIA Centaur)...
