PURPOSE To evaluate endorectal magnetic resonance (MR) imaging and MR spectroscopic imaging for the depiction of locally recurrent prostate cancer after external beam radiation therapy. MATERIALS AND METHODS Endorectal MR imaging and MR spectroscopic imaging were performed in 21 patients with biochemical failure after external beam radiation therapy for(More)
PURPOSE The aim of this study was to measure interfraction prostate bed motion, setup error, and total positioning error in 10 consecutive patients undergoing postprostatectomy radiotherapy. METHODS AND MATERIALS Daily image-guided target localization and alignment using electronic portal imaging of gold seed fiducials implanted into the prostate bed(More)
OBJECTIVE We compared the results of transrectal sonography and endorectal MR imaging in the local staging of prostatic carcinoma. SUBJECTS AND METHODS 56 patients (mean age, 61.1 +/- 7.3 years) with the diagnosis of prostate cancer who by transrectal sonography had no evidence of gross extracapsular extension underwent endorectal coil MR imaging prior to(More)
OBJECTIVES To define the potential role of cryosurgical ablation of the prostate (CSAP) as a treatment option for patients with localized prostate carcinoma (PCA), we performed a retrospective outcomes analysis of a large database of patients undergoing CSAP constructed from five institutions and compared this with matching outcomes from contemporary(More)
PURPOSE We define the optimal systematic biopsy regimen to detect carcinoma of the prostate. MATERIALS AND METHODS A total of 483 consecutive patients referred for an abnormal digital rectal examination and/or prostate specific antigen (PSA) 4.0 ng./ml. or greater underwent transrectal ultrasound and systematic biopsy. Lateral biopsies of the peripheral(More)
What's known on the subject? and What does the study add? Very few comparative studies to date evaluate the results of treatment options for prostate cancer using the most sensitive measurement tools. PSA has been identified as the most sensitive tool for measuring treatment effectiveness. To date, comprehensive unbiased reviews of all the current(More)
Ultrasonography is an inexpensive, noninvasive, and reliable means of evaluating the integrity of the distal seminal tract. A variety of rare congenital anomalies can be demonstrated by ultrasound applied either transabdominally or by the transrectal route. Ultrasonography provides a unique insight into the function and pathology of ejaculation that may(More)
OBJECTIVES To define the sonographic characteristics of local cancer recurrence after radical prostatectomy. METHODS in 114 patients with an elevated prostate-specific antigen (PSA) and negative bone scan, 156 ultrasound-guided prostate fossa biopsies were carried out. RESULTS in 53.5%, biopsy proved local recurrence. More than one ultrasound-guided(More)
PURPOSE Active surveillance (AS) is an option for the initial management of early-stage prostate cancer. Current risk stratification schema identify patients with low-risk disease who are presumed to be most suitable for AS. However, some men with higher risk disease also elect AS; outcomes for such men have not been widely reported. PATIENTS AND METHODS(More)
