OBJECTIVE Currently, transrectal ultrasound-guided (TRUS) systematic prostate biopsy is the standard procedure in the diagnosis of prostate cancer. Although TRUS-guided prostate biopsy is a safe method, it is an invasive procedure that is not free from complications. In this prospective study we evaluated the complications of a TRUS-guided 12-core prostate biopsy. MATERIAL AND METHODS The stu...
Prostate cancer is the most common cancer in men, with a one in eight lifetime risk and 46,690 new cases diagnosed in the UK in 2014. Between 1979 and 2011 the incidence of prostate cancer in the UK has increased by 155%. The introduction of PSA testing and systematic transrectal ultrasound (TRUS) biopsies is responsible for a significant proportion of these new diagnoses. Over the same period ...
PURPOSE In clinical practice, atypical small acinar proliferation (ASAP) and high-grade prostatic intraepithelial neoplasia (HGPIN) are two common findings on prostate biopsies. Knowing the frequency of a prostate cancer diagnosis on repeat biopsies would aid primary treating physicians regarding their decisions in suspicious cases. MATERIALS AND METHODS One hundred forty-three patients in wh...
PURPOSE To identify the prostate cancer detection rate on the patients who had second prostate biopsy out of the patients who were reported negative in their first biopsy. MATERIALS AND METHODS From July 2006 to February 2012, prostate biopsy was performed on 843 patients with over 4 ng/ml and on 618 biopsy negative patients PSA was performed from between 6 months and 9 months after biopsy. O...
Prostate cancer affects 1 in 6 men in the USA. Systematic transrectal ultrasound (TRUS)-guided biopsy is the standard method for a definitive diagnosis of prostate cancer. However, this "blind" biopsy approach can miss at least 20% of prostate cancers. In this study, we are developing a PET/CT directed, 3D ultrasound image-guided biopsy system for improved detection of prostate cancer. In order...
Transperineal prostate biopsy is a procedure that can be used to obtain histological samples from the prostate. To improve both the quality of the biopsy core samples and prostate cancer detection, we are currently performing a prospective, randomized trial comparing prostate biopsy samples obtained using an 18 G-needle to those obtained using a 16 G needle. The aim of this preliminary study wa...
PURPOSE To evaluate the effectiveness of 2 more core prostate biopsy protocol in detecting the prostate cancer (PCa) by comparing 10-core prostate biopsy with 12-core according to the prostate-specific antigen (PSA) level and the prostate volume. MATERIALS AND METHODS A total of 474 men with elevated serum levels of PSA between 2.5 and 20.0 ng/mL, regardless of abnormal finding on digital rec...
Background: In recent years the use of Prostate Specific Antigen test (PSA) has reduced the mortality rate of prostate cancer. Certain factors by affecting the levels of PSA, decrease or increase prostate cancer detection. Some studies suggest the effect of body weight and Body Mass Index (BMI) on PSA, while some others are contrary to the opinion mentioned.. Hence, in this study we ex...
PURPOSE To evaluate the effectiveness of digital rectal-compression immediately after transrectal prostate biopsy (P-bx) for improving the accuracy of prostate cancer (PCa) staging. MATERIALS AND METHODS Between July 2008 and June 2010, 94 consecutive patients who had a radical prostatectomy were included in our retrospective analysis. The exclusion criteria included a history of previous P-b...
PURPOSE We aimed to evaluate the efficacy of magnetic resonance imaging (MRI)-directed cognitive fusion transrectal ultrasonography (TRUS)-guided anterior prostate biopsy for diagnosis of anterior prostate tumors and to illustrate this technique. METHODS A total of 39 patients with previous negative TRUS biopsy, but high clinical suspicion of occult prostate cancer, prospectively underwent pr...
