PURPOSE We determined the incidence of positive pelvic lymph nodes in men undergoing radical retropubic prostatectomy and describe the correlation with prostate specific antigen, histological grade and stage. We examined whether tumor cells are localized in the sentinel nodes only or also in other nonsentinel lymph nodes. MATERIALS AND METHODS A total of(More)
OBJECTIVES To determine how many men with high-risk prostate cancer (prostate-specific antigen [PSA]>20 ng/ml or biopsy Gleason score 8-10) have positive lymph nodes (sentinel lymph nodes [SLNs] and nonsentinel lymph nodes [NSLNs]) and whether these positive nodes are localised in the region of SLN dissection or in other regions, too. METHODS In 228 men(More)
Sentinel lymph node dissection (SLND) has replaced extended lymphadenectomy for nodal staging in several solid tumours. We present our results of SLND in prostate cancer in regard to detection and false-negative rate. In a 2-day protocol about 300 MBq 99mTc-nanocolloid are injected into the prostate. Two hours later static scans of the pelvis are performed(More)
AIM Evaluation of the significance of lymphoscintigraphy and intraoperative probe measurement for the identification of the sentinel lymph node (SLN) in prostate cancer. PATIENTS AND METHOD In 117 patients with prostate cancer scintigrams in various projections were acquired till approximately 6 hours p.i. after ultrasound guided transrectal(More)
OBJECTIVE To investigate the reliability of preoperative diagnostics in predicting the true histopathological stage and grade of prostate cancer, and to examine whether lymph node (LN) metastases in unilateral prostate cancer are located unilaterally and therefore whether it is justified to dissect only the ipsilateral LNs in presumed unilateral disease.

OBJECTIVE To investigate how many men with low-risk prostate cancer had positive lymph nodes detected by radio-guided surgery and whether they had a higher biochemical relapse rate after radical prostatectomy, because in such patients most urologists dispense with operative lymph node staging, as nomograms indicate only a low percentage of lymph node(More)
UNLABELLED The clinical significance of (18)F-FDG-PET/CT in the follow-up of patients with differentiated thyroid carcinoma was evaluated and the results were compared with those of (18)F-FDG-PET, (131)I-whole-body scintigraphy including SPECT/CT (WBS) and ultrasound. In addition, it was the aim to investigate the impact of (18)F-FDG-PET/CT on the(More)
AIM To visualise the sentinel lymph nodes (SLNs) of the prostate we injected the radiotracer into the parenchyma of the prostate. The activity was deposited in liver, spleen, bone marrow, urinary bladder and regional lymphatic system. The aim of this work is to determine biokinetical data and to estimate radiation doses to the patient. METHODS The(More)
