Is the Recommendation of a Pelvic Lymphadenectomy in Conjunction with Radical Prostatectomy in Prostate Cancer Patients Justified? Report from a Multidisciplinary Expert Panel Meeting.

Introduction: Pelvic lymphadenectomy (pLA) in prostate cancer (PCa) is one of the most common uro-oncologic surgical procedures. An increased complication rate is accompanied by unproven oncologic benefit. Extent of pLA and mechanisms of metastasis are discussed controversially.

[Secondary malignancies in urinary diversions].

In contrast to ureterosigmoidostomy no reliable clinical data exist for tumor risk in different forms of urinary diversion using isolated intestinal segments.In 44 German urological departments, operation frequencies, indications, patient age, and operation dates of the different forms of urinary diversion, operated between 1970 and 2007, could be registered. The secondary tumors up to 2009 were registered as well and related to the numbers of the different forms of urinary diversions resulting in tumor prevalences.

Perioperative activation of disseminated tumor cells in bone marrow of patients with prostate cancer.

Purpose: The outcome of prostate cancer is highly unpredictable. To assess the dynamics of systemic disease and to identify patients at high risk for early relapse we followed the fate of disseminated tumor cells in bone marrow for up to 10 years and genetically analyzed such cells isolated at various stages of disease.

Patients And Methods: Nine hundred bone marrow aspirates from 384 patients were stained using the monoclonal antibody A45-B/B3 directed against cytokeratins 8, 18, and 19.

Radioguided surgery in urological malignancies.

The current literature was reviewed for articles focusing on radioguided surgery in urological malignancies.In penile cancer sentinel lymph node dissection is part of international guidelines. By detailed histopathological analysis (serial sections, immunohistochemical staining) more micrometastases are detectable improving the histopathological staging.

[Sentinel node dissection in prostate cancer: current status].

Sentinel lymph node (SLN) dissection is an excellent staging procedure with high sensitivity (>95%) for detecting positive nodes. When the sentinel node is negative, there is high certainty that other lymph nodes are also negative. Limitations of this technique include the use of hormone therapy over several months and a preceding transurethral resection or suprapubic adenomectomy.
