As recommended by current NCCN guidelines, patients with very low-risk prostate cancer may be treated with active surveillance (AS), but this may be underutilized. Using the National Cancer Database (NCDB), we identified men (2010-2013) with biopsy-proven, very low-risk prostate cancer that met AS criteria as suggested by Epstein (stage ≤ T1c; Gleason score (GS) ≤ 6; PSA < 10; and ≤2 [or <33%] positive biopsy cores) and aged ≤76, and low comorbidity index (Charlson-Deyo score = 0). For those patients meeting this criteria, we performed generalized estimation equation (GEE) method with incorporation of correlation in patients clustered within facility to determine the likelihood of undergoing AS...

AIMS: Prostate cancer (PrCa) is the most frequently diagnosed non-cutaneous cancer in men. Without clear pathological indicators of disease trajectory at diagnosis, management of PrCa is challenging, given its wide-ranging manifestation from indolent to highly aggressive disease. This study examines the role in PrCa of the Pygopus (PYGO)2 chromatin effector protein as a risk stratification marker in PrCa. METHODS: RNA expression was performed in PrCa cell lines using Northern and RT-PCR analyses...

BACKGROUND: Five-year survival in patients with localized prostate cancer (PCa) is nearly 100%, but metastatic disease still remains incurable. Clinical management of metastatic patients has become increasingly complex as novel therapeutic strategies have emerged. This study aims at evaluating the impact of the first metastatic progression on the outcome of PCa patients treated with curative intent. METHODS: The analysis was conducted using data of 913 cases of localized PCa diagnosed between 2000 and 2014...

BACKGROUND: Besides clinical stage and Gleason score, risk-stratification of prostate cancer in the pretherapeutic setting mainly relies on the serum PSA level. Yet, this is associated with many uncertainties. With regard to therapy decision-making, additional markers are needed to allow an exact risk prediction. Eukaryotic translation elongation factor 1 alpha 2 (EEF1A2) was previously suggested as driver of tumor progression and potential biomarker. In the present study its functional and prognostic relevance in prostate cancer was investigated...

BACKGROUND: The majority of kidney transplants are performed in recipients (RTR) over 50; simultaneously their life expectancy is improving. The increasing age and number of RTR is likely to be paralleled by an increase of prostate cancer (PCa) incidence. However, little is known on the optimal management of these patients who represent a therapeutic challenge due to medical and anatomical graft-related issues. METHODS: AMED, Medline and Embase were searched until November 17(th) , 2016 adhering to the PRISMA guidelines and the AMSTAR checklist to investigate oncological and functional outcomes of PCa treatment in RTR...
