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...
Autopsy studies of men without known prostate cancer suggest that a substantial reservoir of prostate cancer that does not cause symptoms or death exists within the population. The majority of these cancers are Gleason 6 tumors and are frequently detected by prostate-specific antigen-based prostate cancer screening.There is strong evidence from longitudinal cohort studies of men with both treat...
BACKGROUND Men of Black African descent are known to have the highest incidence of prostate cancer. The disease is also more aggressive in this group possibly due to biologically more aggressive tumor or late presentation. Currently, serum prostate-specific antigen (PSA) assay plays a significant role in making the diagnosis of prostate cancer. However, the obtained value of serum PSA may not d...
BACKGROUND Human glandular kallikrein (hK2) has been shown to add important information regarding the early detection and staging of prostate cancer. Preliminary analysis pointed out that hK2 may discriminate between pT2 and pT3 tumors, and that hK2 may predict Gleason grade 4/5 cancer volume, better than prostate-specific antigen (PSA) or percent free PSA (%fPSA). We investigated the role of h...
Studies on the relationship between obesity and prostate cancer incidence are inconsistent. In part, this inconsistency may be due to a differential effect of obesity on low-grade and high-grade cancer or confounding of the association of obesity with prostate cancer risk by diabetes. We investigated the associations of obesity and diabetes with low-grade and high-grade prostate cancer risk. Da...
PURPOSE To predict the malignant potential of prostate cancer (PCa) according to prostate-specific antigen velocity (PSAV), PSA density (PSAD), free/total PSA ratio (%fPSA), and digital rectal examination (DRE). MATERIALS AND METHODS From January 2009 to December 2012, 548 adult male patients were diagnosed with PCa by prostate biopsy at four hospitals in Korea. We retrospectively analyzed 15...
Prostate cancer is the most commonly diagnosed cancer in men and the second leading cause of cancer related mortality. Localized prostate cancer is treated by either radical pros‐ tatectomy or radiotherapy. Low levels of testosterone have been associated with prostate cancer progression. These tumor presented advanced tumor stage, high Gleason scores, and had significantly worse overall surviva...
Our aim was to study the level of interobserverconcordance in the Gleason scores of prostate needlebiopsy specimens reported at 1 institution. Aretrospective review of all prostate needle biopsyspecimens in which a diagnosis of adenocarcinoma wasmade during the year 2000 was conducted. Parametersevaluated included the Gleason score, Gleason gradesidentified, the perc...
Answer questions and earn CME/CNE The eighth edition of the American Joint Committee on Cancer (AJCC) tumor-node-metastasis (TNM) Staging Manual has been updated and improved to ensure the highest degree of clinical relevance and to improve its utility for patient evaluation and clinical research. Major changes include: 1) pathologically organ-confined disease is now considered pT2 and is no lo...
