BACKGROUND: Metastatic spreading to the lungs is a negative prognostic factor in patients with prostate cancer (PC). Aim of our study was to assess the prevalence of lung PC metastases in patients with fluorine-18 fluoroethyl-choline (F-18-FECh) PET-CT positive lung lesions and the role of Gleason Score (GS) and common biochemical markers in predicting metastatic spreading to the lungs. METHODS: We retrospectively evaluated the scans of 1283 patients ongoing (F-18-FECh) PET-CT for PC between May 2010 and July 2014...

There is an unmet clinical need for adequate biomarkers to aid risk stratification and management of prostate cancer (PCa) patients. Even within the high-risk PCa category not all patients will invariably have a poor prognosis, and improved stratification of this heterogeneous group is needed. In this context, components of the hedgehog (Hh) pathway may have promise as biomarkers, as the available evidence suggests increased Hh pathway activity may confer a poorer outcome in advanced and castrate-resistant PCa...

BACKGROUND: Noninvasive biomarkers to guide personalized treatment for castration-resistant prostate cancer (CRPC) are needed. In this study, we analyzed hypermethylation patterns of two genes (GSTP1 and APC) in plasma cell-free DNA (cfDNA) of CRPC patients. The aim of this study was to analyze the cfDNA concentrations and levels of the epigenetic markers and to assess the value of these biomarkers for prognosis. METHODS: In this prospective study, patients were included before starting new treatment after developing CRPC...

Prostate cancer is a highly heterogeneous disease, with remarkably different prognosis across all stages. Increased circulating tumor cell (CTC) count (≥ 5) using the CellSearch assay has been identified as one of the markers that can be used to predict survival, with added value beyond currently available prognostic factors. Recently, androgen receptor splice variant 7 (AR-V7) detection has been associated with worse outcomes for patients with castration-resistant prostate cancer (CRPC) treated with novel androgen receptor-signaling (ARS) inhibitors such as abiraterone and enzalutamide but not taxane chemotherapies...

The phosphatidylinositol 3-kinase (PI3K)/AKT/mTOR pathways and Bcl-2 family play a central role in prostate cancer (PC). The aim was to determine influence in the biochemical progression in PC. To evaluate the association between clinic pathological and immunohistochemical variables, Spearman's test was performed. Log-rank test and Kaplan-Meier curves were used for survival comparisons. To explore the correlation of the studied immunohistochemical parameters and the established prognostic variables with biochemical progression, univariate and multivariate Cox proportional Hazard regression analyses were performed...

Molecular diagnostics is a rapidly evolving area of surgical pathology, that is gradually beginning to transform our diagnostical procedures for a variety of tumors. Next to molecular prognostication that has begun to complement our histological diagnosis in breast cancer, additional testing to detect targets and to predict therapy response has become common practice in breast and lung cancer. Prostate cancer is a bit slower in this respect, as it is still largely diagnosed and classified on morphological grounds...

Tumor protein D54 (TPD54) has been reported to be involved in the prognosis of several cancers. However, the involvement of TPD54 in prostate cancer (PCa) is yet to be elucidated. In the present study, 117 patients with PCa were enrolled. The mRNA and protein levels of TPD54 in PCa tissues and adjacent normal prostate tissues were analyzed by quantitative polymerase chain reaction and western blotting. TPD54 expression was also determined by immunohistochemistry (IHC) in paraffin-embedded PCa tissues. The association between TPD54 expression and clinicopathological features and prognosis was evaluated...

INTRODUCTION: The association between lower-extremity venous thrombosis and cancer is well-established. However, the extent to which upper-extremity deep venous thrombosis (U-DVT) is a marker of cancer and a prognostic factor for all-cause mortality remains poorly understood. We examined the risk of cancer after a diagnosis of U-DVT compared with cancer risk in the general population. MATERIALS AND METHODS: Using Danish nationwide population-based medical registries, we identified all patients with first-time U-DVT during 1980-1993 and 2000-2013...

BACKGROUND: Neutrophil-lymphocyte ratio (NLR) is a widely used, representative marker of systemic inflammatory response within the body. NLR can be calculated from simple, inexpensive peripheral blood samples. High NLR is a negative prognostic factor in a variety of malignancies including urological tumors. In this study, we aim to assess the prognostic value of preoperative neutrophil- lymphocyte ratio (NLR) in patients treated with radical prostatectomy (RP) for localized prostate cancer (PCa)...

Cancer cells hijack metabolic pathways to support bioenergetics and biosynthetic requirements for their uncontrolled growth. Thus, cancer can be considered as a metabolic disease. In this review, we discuss the main metabolic features of prostate cancer with a particular focus on the link between oncogene-directed cancer metabolic regulation, metabolism rewiring, and epigenetic regulation. The potential of using metabolic profiling as a means to predict disease behavior and to identify novel therapeutic targets and new diagnostic markers will be addressed as well as the current challenges in metabolomics analyses...

Secreted protein acidic and rich in cysteine (SPARC) is a secreted matricellular glycoprotein and plays a key role in the development of many tissues and organ types. However, the role of SPARC in prostate cancer (PCa) is still controversial. The aim of the present study was to investigate the abnormalities in the expression of SPARC and its promoter hypermethylation in prostate cancers and in correlated clinicopathological profiles. We examined the hypermethylation of the SPARC promoter as a potential mechanism for suppressing SPARC in PCa...

Prognostic assessment is a key element in the management of patients with prostate cancer as it informs both treatment, follow-up and outcome prediction. Tumour grade should be based upon the novel and evidence-based recommendations of the International Society of Urological Pathology (ISUP) Consensus Conference of 2014, with ISUP grades 1-5 being derived from 2005 ISUP modified Gleason grading, i.e., ISUP grade 1 (3 + 3 = 6), grade 2 (3 + 4 = 7), grade 3 (4 + 3 = 7), grade 4 (3 + 5 = 8, 5 + 3 = 8, 4 + 4 = 8), and grade 5 (4 + 5 = 9 5 + 4 = 9, 5 + 5 = 10)...

BACKGROUND: Overexpression of the androgen receptor (AR) splice variant 7 (AR-V7) has recently been reported to be associated with resistance to antihormonal therapy. Herein, we address the question whether tumor cells with AR-V7 expression can be detected at the time of radical prostatectomy, that is, before long-term hormonal manipulation and castration resistance, and what the potential prognostic impact on the biochemical recurrence (BCR)-free survival may be. METHODS: An anti-AR-V7 antibody was first validated in a training set of prostate cancer specimens by a comparison of AR-V7 protein to AR-V7 mRNA expression...

Prostate cancer is one of the most common cancers among men and can in its later stages cause serious medical problems. Due to the limited suitability of current diagnostic biochemical markers, new biomarkers for the detection of prostate cancer are highly sought after. An ideal biomarker should serve as a reliable prognostic marker, be applicable for early diagnosis, and be applicable for monitoring of therapeutic response. One potential candidate is glutamate carboxypeptidase II (GCPII), also known as prostate specific membrane antigen (PSMA), which has a promising role for direct imaging...

BACKGROUND: The proto-oncogene MYC is implicated in prostate cancer progression. Whether MYC tumor expression at the protein or mRNA level is associated with poorer prognosis has not been well studied. METHODS: We conducted a cohort study including 634 men from the Physicians' Health Study and Health Professionals Follow-up Study treated with radical prostatectomy for prostate cancer in 1983-2004 and followed-up for a median of 13.7 years. MYC protein expression was evaluated using immunohistochemistry, and we used Cox regression to calculate hazard ratios (HRs) and 95% confidence intervals (CIs) of its association with lethal prostate cancer (distant metastases/prostate cancer death)...
