PURPOSE An increase of the serum PSA-level is a sensitive in vitro marker for recurrent prostate cancer. However, it remains difficult to differentiate between local, regional or distant recurrent disease. The aim of this study was to assess the relationship between the detection rate of [(11)C]Choline-PET/CT and the serum PSA-level in patients with a(More)
BACKGROUND In patients with bladder cancer (BCa) preoperative staging with (11)C-choline positron emission tomography-computed tomography (PET/CT) could be used to derive prognostic information and hence stratify patients preoperatively with respect to disease management. METHODS From June 2004 to May 2007, 44 patients with localized BCa were staged with(More)
OBJECTIVE To compare the BTA stat test (BTA stat), a new one-step immunochromatographic assay that can be performed in the urologist's office or in the laboratory, to voided urine cytology and bladder wash cytology (cytology) in the diagnosis and monitoring of cancer of the bladder (BC). METHODS BTA stat and cytology were performed in a double-blinded,(More)
The aim of this study was to prospectively evaluate the value of [11C] Choline PET/CT in monitoring early and late response to a standardized first-line docetaxel chemotherapy in castration refractory prostate cancer (mCRPC) patients. Thirty-two patients were referred for [11C] Choline PET/CT before the start of docetaxel chemotherapy, after one and ten(More)
Purpose: To evaluate the dependency of the sensitivity of [ 11 C]choline positron emission tomography/ computed tomography (PET/CT) for detecting and localizing primary prostate cancer (PCa) on tumor configuration in the histologic specimen. Experimental Design: Forty-three patients with biopsy-proven PCa were included. They underwent radical prostatectomy(More)

PURPOSE PET has been proven to be helpful in the delineation of gross tumour volume (GTV) for external radiation therapy in several tumour entities. The aim of this study was to determine if [(11)C]choline PET could be used to localize the carcinomatous tissue within the prostate in order to specifically target this area for example with high-precision(More)
Transurethral resection of the prostate still represents the "gold standard" in surgical treatment of symptomatic benign prostatic enlargement (BPE). New demands were made on transurethral electrosurgery with the appearance of alternative, minimal invasive procedures. Bleeding complications had to be reduced. Different attempts were made to improve the(More)
UNLABELLED Lymph node involvement is a major prognostic factor in bladder cancer, but the accuracy of conventional imaging modalities for the prediction of regional and distant metastatic diseases is limited. This study was performed to compare the diagnostic accuracies of contrast-enhanced CT and PET with (11)C-choline for the staging of urothelial bladder(More)
BACKGROUND Current imaging techniques are of limited value for lymph node (LN) staging in bladder cancer (BCa) patients scheduled for radical cystectomy (RC). OBJECTIVE Evaluate the diagnostic efficacy of [11C]choline positron emission tomography in combination with computed tomography (PET/CT) for LN staging of patients with BCa scheduled for RC and(More)
