OBJECTIVE To investigate whether prostate-specific antigen (PSA) fluctuation correlates with a prostate cancer and to assess whether PSA fluctuation could be used for diagnosis of prostate cancer. MATERIALS AND METHODS Our study included 229 patients who were performed a prostate biopsy (non-cancer group, 177; prostate cancer group, 52). Enrolled patients were provided twice PSA tests within ...
PURPOSE To evaluate prospectively the role of prostate-specific antigen (PSA) density in predicting Gleason score upgrading in prostate cancer patients eligible for active surveillance (T1/T2, biopsy Gleason score≤6, PSA≤10 ng/mL, and ≤2 positive biopsy cores). MATERIALS AND METHODS Between January 2010 and November 2013, among patients who underwent greater than 10-core transrectal ultrasoun...
Fucosylation is an important oligosaccharide modification associated with cancer and inflammation. We investigated whether urinary fucosylated PSA (Fuc-PSA) levels could be used for the detection of high Gleason score prostate cancer. Urine samples were collected from men with abnormal digital rectal examination findings or elevated serum PSA levels, before prostate biopsy. Lectin-antibody ELIS...
preoperative gleason score (gs) obtained from trans rectal ultra sonography (trus) is the most common grading system to evaluate the appropriate treatment for patients with clinically localized prostate cancer. but this method showed upgraded and downgraded results in comparison to gleason score obtained from radical prostatectomy. the current study aimed to determine clinical or pathological v...
To evaluate the potential role of several clinical and pathological parameters in prediction of seminal vesicle invasion in patients with clinically localized prostate cancer undergoing radical prostatectomy. We retrospectively analyzed the medical records of patients who undergone radical prostatectomy from January 2005 until November 2010. Patients age, prostate volume, PSA, PSA density, perc...
Background and Aim: Prostate cancer is one of the most prevalent type of cancer and the second cause of death among American men. Its prevalence has a direct relationship with increasing age. The present study was carried out to determine the level of prostate specific antigen (PSA) in Birjandi males aged between 40 and 80 years. Material and Methods: In this prospective study, out of 62...
When used alone, prostate-specific antigen (PSA) is not sufficiently sensitive or specific to consider it an ideal tool for the early detection or staging of prostate cancer. To optimize the use of PSA, the concepts of PSA velocity, PSA density, and age-related PSA values were developed. Although PSA velocity provides excellent results, its determination requires three PSA values over a 2-year ...
