PURPOSE The factors that predict prostate cancer detection on repeat biopsy were evaluated in patients with atypical small acinar proliferation (ASAP) on the initial biopsy. MATERIALS AND METHODS From 2003 to 2008, 3,130 men with suspected prostate cancer underwent a prostate needle biopsy, and 244 (7.8%) were diagnosed as having ASAP. One hundred seventy of 244 patients were rebiopsied at le...

The aim of this study was to define the relation between silver stained nucleolar organizer regions (AgNORs) count and histological grade, and clinical stage in needle biopsy specimens of 65 prostatic adenocarcinomas. Histological grade was determined according to the modified Gleason system. AgNORs were evaluated by the counting method on routine histological sections stained with silver. Ther...

results a total number of 43 specimens were studied, from which 9 were obtained from patients with metastatic prostate cancer. the expression of five examined genes had no correlation with psa level and gleason score. the expression of amacr decreased in metastatic prostate cancer (p = 0.02). the expression of other genes showed no difference between metastatic and non-metastatic tumors (p > 0....

PURPOSE To investigate the incidence, clinical features, pathogenic bacteria, and risk factors associated with acute prostatitis after transrectal prostate biopsy. MATERIALS AND METHODS We retrospectively reviewed the medical records of 923 transrectal ultrasound-guided needle biopsies of the prostate in 878 patients performed at our institution from June 2004 to May 2009. The indications for...

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...

MRI-targeted biopsy of the prostate appears to have the potential to reduce the high rates of underdiagnosis and overdiagnosis associated with the current diagnostic standard of transrectal ultrasound guided systematic biopsy. Direct or "in bore" MRI-guided biopsy is one of the three methods for MRI-targeted core needle sampling of suspicious, generally Pi-RADS 4 or 5, foci within the prostate,...

This study aims to present the origins and the historical evolution of fine-needle aspiration biopsy and to also underline its importance in the history of modern cytology. The article focuses on the advances made in the 20th century that have led to the modern techniques associated with the procedure. The authors conducted a thorough review of early reports on needle biopsy, particularly those...

In July 2016 an 83-year-old male was referred to our institution for evaluation of a serum prostate antigen (PSA) level of 8, 79 ng/ml. The patient had personal history of hypertension and pancytopenia. He had personal or family history of malignancy. Levels of serum prostatic acid phosphatase (PAP) and carcinoembryonic antigen (CEA) were normal. Physical examination, including digital rectal e...

because of superficial location and not being covered by boney structure, thyroid is the ideal organ for 2-dimensional gray scale ultrasonography. availability of relatively low cost equipment and ever increasing number of endocrinologists with expertise in thyroid ultrasound has made it an integral part of thyroid practice in the office of endocrinologists. in particular, the current recommend...
