BACKGROUND Transrectal ultrasound guided biopsy of the prostate is the most common modality used to diagnose prostate cancer. OBJECTIVES The aim of this study was to evaluate the optimal number of cores at prostate biopsy, which have the most diagnostic value with least adverse effects. PATIENTS AND MATERIALS Transrectal ultrasonography (TRUS) guided biopsy was performed in 180 patients sus...

PURPOSE To evaluate parameters for determining repeat prostate biopsy in patients with 5α-reductase inhibitor (5ARI) treatment after initial negative biopsy. MATERIALS AND METHODS From January 2007 to December 2015, patients who underwent a repeat prostate biopsy after an initial negative biopsy were enrolled from multiple institutions. Serial prostate-specific antigen (PSA) levels after the ...

PURPOSE We evaluated the clinical utility of the PCA3 assay in guiding initial biopsy decisions in prostate cancer. MATERIALS AND METHODS A European, prospective, multicenter study enrolled men with a serum total prostate specific antigen of 2.5 to 10 ng/ml scheduled for initial biopsy. After digital rectal examination first catch urine was collected. PCA3 scores were determined using the PRO...

PURPOSE OF REVIEW We review recent literature surrounding the use of prebiopsy prostate MRI and MRI-targeted biopsy in men at risk for prostate cancer. RECENT FINDINGS Large series have strengthened the case for the use of MRI prior to prostate biopsy to maximize the detection of clinically significant disease, reduce the detection of clinically insignificant disease, and allow for tumor loca...

INTRODUCTION Despite all preventive measures and improved biopsy techniques, serious, life-threatening complications of prostate biopsy, including sepsis, still exist. In the present study, in order to identify the risk factors that may be associated with sepsis development after prostate-biopsy, we aimed to analyze retrospectively the data of our patients who underwent transrectal ultrasound-g...

Approximately 70% of men with a raised total serum PSA, defined as >4.0ng/ml will have an initial prostate biopsy negative for cancer. However, a persistently elevated PSA after initial biopsy is a relevant clinical problem and the decision to repeat the prostate biopsy in these patients is a common dilema. Prostate biopsy is not without morbidity; 1% of patients suffer sepsis or severe hemorrh...

BACKGROUND We evaluated the cancer detection rate of prostate cancer using transperineal template-guided saturation biopsy aimed at sampling one core for each milliliter of prostate volume for patients requiring repeated prostate biopsies. METHODS In total, 103 consecutive patients with repeated prostate biopsies were enrolled in this retrospective study. The number of biopsy cores was define...

OBJECTIVES Prostate biopsy involvement and Gleason score guide treatment decisions in prostate cancer. We evaluated concordance in Gleason score and laterality between biopsy and radical retropubic prostatectomy (RRP) specimens and factors that influenced this relationship. MATERIALS AND METHODS We reviewed 538 prostate cancer diagnoses at a Veterans Affairs medical center (2000-2005) to iden...

68Ga Prostate-specific membrane antigen (PSMA) is an increasingly popular radiopharmaceutical tracer in prostate cancer and is becoming increasingly researched in other cancers such as breast cancer, renal cell carcinoma, glioblastoma multiforme, among others. Cholangiocarcinoma is the second most common primary hepatic malignant tumor; it is an aggressive tumor with a 5-year surviva...

BACKGROUND Quinolone is recommended as an antimicrobial prophylaxis to prevent infectious complication after transrectal ultrasound-guided biopsy, but the increased appearance of quinolone-resistant organism has raised concerns about the efficacy of quinolone. The current study was performed to evaluate various clinical factors including antimicrobial regimens associated with infectious complic...
