In this study, the ultrasound-assisted extraction of polysaccharides (PSA) from Pinelliae Rhizoma Praeparatum Cum Alumine (PRPCA) was optimized by response surface methodology (RSM). The structural characteristics of PSA were analyzed by UV-vis spectroscopy, infrared spectroscopy, scanning electron microscopy, high performance gel permeation chromatography and high performance liquid chromatogr...

PURPOSE Controversy exists as to whether current pretreatment prostate-specific antigen (PSA) dynamics enhance outcome prediction in patients undergoing treatment for prostate cancer. We assessed whether pretreatment PSA velocity (PSAV) or doubling time (PSADT) predicted outcome in men undergoing radical prostatectomy and whether any definition enhanced accuracy of an outcome prediction model. ...

OBJECTIVE To assess the prognostic significance of positive surgical margins (PSMs) after minimally invasive radical prostatectomy (MIRP) in interaction with other established prognosis factors. PATIENTS AND METHODS We retrospectively analysed data prospectively collected between 1998 and 2010 for 4628 consecutive patients who underwent MIRP for clinically localized prostate cancer. The impac...

High Body mass index (BMI) has been directly associated with risk of aggressive or fatal prostate cancer. One possible explanation may be an effect of BMI on serum levels of prostate-specific antigen (PSA). To study the association between BMI and serum PSA as well as prostate cancer risk, a large cohort of men without prostate cancer at baseline was followed prospectively for prostate cancer d...

OBJECTIVES Considerable evidence has shown that diet can affect both the incidence and the progression of prostate cancer. The objective of this study was to determine whether men in this situation could make a change to a diet emphasizing plant-based foods and fish and to examine the effect on quality of life (QOL) and prostate-specific antigen (PSA) velocity. METHODS A total of 36 men and t...

BACKGROUND All authorities recommend against prostate specific antigen (PSA) screening in men 75 years and older. However, some primary care physicians (PCPs) continue to have high rates of PSA, with large variation in testing. We assessed the tests, treatments, and payments for prostate cancer care in men aged 75 or older who have PCPs with high or low PSA testing rates. METHODS We performed...

BACKGROUND A possible association between the level of prostate specific antigen (PSA) and the use of some commonly prescribed medications has been reported in recent studies. Most of these studies were carried out in general populations of men who were screened for prostate cancer using the PSA test. We reported on the association between the initial PSA level and the use of statins, metformin...

BACKGROUND We retrospectively evaluated the prognostic impact of neutrophil-lymphocyte ratio (NLR) as a marker for inflammatory and immune state in men with progressive metastatic castration resistant prostate cancer (mCRPC) following docetaxel. METHODS The SUN-1120 phase III trial comparing prednisone combined with sunitinib (n = 584) or placebo (n = 289) for mCRPC following docetaxel-based ...

  Abstract   Background: Regarding the variety of tests present for detecting and also screening   prostate cancer and also bearing in mind the advantages and disadvantages of   these tests we decided to re-evaluate these tests (total prostate specific antigen and all   of its modifications) in detecting prostate cancer in men with intermediate serum   PSAlevels.   Methods: Following a cross se...

Anthropometric measurements, e.g., body weight (BW), body mass index (BMI), as well as serum prostate-specific antigen (PSA) and percent-free PSA (%fPSA) have been shown to have positive correlations with total prostate volume (TPV). We developed an equation and nomogram for estimating TPV, incorporating these predictors in men with benign prostatic hyperplasia (BPH). A total of 1852 men, inclu...
