The abnormally expressed LncRNAs played irreplaceable roles in the prognosis of prostate cancer (PCa). Therefore, we conducted this systematic review and meta-analysis to summarize the association between the expression of LncRNAs, prognosis and clinicopathology of PCa. 18 eligible studies were recruited into our analysis, including 18 on prognosis and 9 on clinicopathological features. Results indicated that aberrant expression of LncRNAs was significantly associated with biochemical recurrence-free survival (BCR-FS) (HR = 1...

Y-box binding protein 1 (YB-1) is an RNA and DNA binding factor with potential prognostic cancer. To evaluate the clinical impact of YB-1, a tissue microarray with 11,152 prostate cancers was analysed by immunohistochemistry. Cytoplasmic and nuclear staining was separately analysed. Cytoplasmic YB-1 was absent or weak in normal epithelium but seen in 86,3% of carcinomas. Cytoplasmic staining was weak, moderate, and strong in 29.6%, 43.7% and 13.0% of tumours and was accompanied by nuclear YB-1 staining in 32...

REVIEW
Juan D Garisto, Laurence Klotz
Prostate cancer is the most common malignancy affecting men. There has been a nearly 70% increase in new prostate cancer cases, mostly classified as low risk, that have been diagnosed in early stages as a consequence of prostate-specific antigen (PSA) screening. Data regarding the natural history of this disease confirm the clinical insignificance of low-grade prostate cancer, which is associated with scant or no metastatic dissemination. Active surveillance is a conservative management approach, conducted for those patients with "low-risk" or "favorable-risk" disease, which avoids long-term adverse effects on the patient's quality of life...

The presence and extent of cribriform pattern of prostate cancer portend recurrence and cancer death. Therelative expressions within this morphology of the prognostically adverse loss of PTEN, and the downstream inactivation of cell cycle inhibitor p27/Kip1 had been uncertain. In this study, we examined 52 cases of cribriform cancer by immunohistochemistry (IHC) for PTEN, p27, and CD44 variant (v)7/8, and a subset of 17 casesby chromogenic in situ hybridization (ISH) using probe for PTEN or CDKN1B (gene for p27)...

INTRODUCTION: The 4Kscore Test is a prebiopsy blood test that incorporates four prostate protein biomarkers along with patient clinical information to determine a man's risk for high-grade, aggressive (Gleason ≥7) prostate cancer. However, some men likely to benefit from the test may be seen in primary care settings where the digital rectal examination (DRE) information is not always obtained. In this study, we assessed the clinical validity of the 4Kscore Test when the DRE information was not included in the algorithm...

Links between metabolic syndrome and prostate cancer after androgen deprivation therapy are emerging. The aim of the research was to investigate the association of metabolic syndrome and aggressive prostate malignancy, at initial diagnosis, without the influence of hormonal treatment. Retrospective analysis of 133 patients with prostate tumor diagnosis between 2007 and 2009 was conducted. Patients with prostate cancer were subdivided in 2 groups according to Gleason score: Gleason score≥7 as high-grade prostate tumor (Group 1) and <7 (Group 2) as low-grade prostate tumor...

PURPOSE: Gleason score upgrading should be considered when indicating surgery in prostate cancer (PCa) patients. In elderly patients, definitive treatment of low-risk PCa must be weighed with the risks of overtreatment. Our aim was to evaluate rates of Gleason score upgrading in patients ≥75 years undergoing radical prostatectomy (RP) for localized PCa and to identify predictors associated with upgrading. METHODS: 3296 patients undergoing RP were retrospectively evaluated and categorized into age groups: <70 years (n = 2971) vs...

Prostate Cancer (PCa) is a complex and heterogeneous disease. The androgen receptor (AR) and the signal transducer and activator of transcription 3 (STAT3) could be effective targets for PCa therapy. STAT3, a cytoplasmatic latent transcription factor, is a hub protein for several oncogenic signalling pathways and up-regulates the expression of numerous genes involved in tumor cell proliferation, angiogenesis, metastasis and cell survival. STAT3 activity can be modulated by several Post-Translational Modifications (PTMs) which reflect particular cell conditions and may be implicated in PCa development and progression...

INTRODUCTION: Transrectal rectal ultrasound (TRUS)-guided systematic biopsy is the gold standard for diagnosis of prostate cancer. However, systematic biopsy has high false-negative rate and often misses anteriorly located tumors. Magnetic resonance imaging (MRI)-TRUS fusion biopsy can potentially improve cancer detection by better visualization and targeting of cancer focus. We evaluated the role of fusion biopsy in detection of prostate cancer and the association of prostate imaging reporting and data system (PI-RADS) score for predicting cancer risk and its aggression...

Polymorphisms of the base excision repair gene APE1 may be associated with an increased risk for developing prostate cancer. In other cancer types, altered APE1 protein expression is a candidate prognostic marker. Using immunohistochemistry, we thus analyzed APE1 expression in 9,763 prostate cancers in a tissue microarray (TMA) with attached clinical and molecular data. The comparison with normal prostate tissue revealed an upregulation of APE1 in cancer samples. APE1 immunostaining was considered weak in 20...

Programmed cell death protein 1 (PD-1) and its ligand Programmed death ligand 1 (PD-L1) have gained massive attention in cancer research due to recent availability and their targeted antitumor effects. Their role in prostate cancer is still undetermined. We constructed tissue microarrays from prostatectomy specimens from 535 prostate cancer patients. Following validation of antibodies, immunohistochemistry was used to evaluate the expression of PD-1 in lymphocytes and PD-L1 in epithelial and stromal cells of primary tumors...

Numerous investigations have addressed the correlation between MMP2-1306C/T polymorphism and prostate cancer (PCa) susceptibility. However, these conclusions were controversial. Thus, we conducted this current meta-analysis based on six studies from PubMed, Embase, Cochrane Library, China Biology Medicine disc (CBM), China National Knowledge Infrastructure (CNKI) up to October 21st, 2016. Odds ratios (ORs) with 95% confidence intervals (CIs) were calculated to evaluate the strength of the correlations. Additionally, different subgroup analyses and publication bias tests were performed...
