The Onkonet database: taking stock of an Internet-based, multi-centre database on surgical prostate cancer treatment.

CONCLUSIONS:  Comprising 21 474 documented patients and over 200 parameters, Onkonet is one of the most comprehensive clinical registers for the documentation of prostate cancer patients in Germany. The data analysis showed that the limitations of such a database are mainly due to the high number of parameters and the high susceptibility to errors due to manual data submission.

Authors: Murray NP, Aedo S, Fuentealba C, Salazar A, Reyes E, Lopez MA, Minzer S Abstract INTRODUCTION: Minimal residual disease (MRD) is that which persists after curative treatment for prostate cancer. It has the potential to grow and cause metastasis. The detection of circulating prostate cells (CPCs) and bone marrow micro-metastasis could represent different sub-types of MRD. OBJECTIVE: To determine biochemical failure free survival and time to failure, the presence of circulating prostate cells and bone marrow micro-metastasis in men treated for low risk prostate cancer. HYPOTHESIS: The presence of MRD...

Abstract OBJECTIVES: To investigate the prognostic utility of multifocal extraprostatic extension (EPE) on biochemical recurrence after radical prostatectomy. METHODS: We conducted retrospective analysis of biochemical recurrence and prognostic pathologic variables in 673 men with stage pT3a/pT3b prostate cancer from 2000 to 2012. Extent of EPE on radical prostatectomy was divided into three groups: focal EPE (tumor dimension

AbstractSimple prostatectomy is an option for management of patients with enlarged prostates and obstructive symptoms. However, the guidelines still do not state a gold-standard treatment for men with BPH and some of these patients with BPH are also known to harbor prostate cancer. This issue can be a challenge because, in the traditional simple prostatectomy, the prostate capsule is often left in place, and that is usually the area of the prostate cancers. With the robotic approach, our goal is to analyze the outcomes of modified simple prostatectomy (MSP) by the elimination of the entire prostate tissue. Thirty-four pati...

Patients diagnosed with clinically node-positive prostate cancer represent a population that has historically been thought to harbor systemic disease. Increasing evidence supports the role of local therapies in advanced disease, but few studies have focused on this particular population. In this review we discuss the limited role for conventional cross sectional imaging for accurate nodal staging and how molecular imaging, although early results are promising, is still far from widespread clinical utilization. To date, evidence regarding the role of radical prostatectomy and pelvic lymph node dissection in clinically node-...

The objective of the present study was to evaluate the beneficial effect of endorectal power Doppler/grayscale ultrasound-guided biopsy over that of mpMRI/TRUS-guided biopsy for decision-making regarding prostatectomy in males with a high risk of prostate cancer. Data regarding endorectal power Doppler/grayscale ultrasound-guided biopsies and mpMRI/TRUS-guided biopsies of 1,094 males with elevated specific prostate antigen, were included. Radical prostatectomy was performed in males aged

Two cases with 68Ga-PSMA–avid prostate cancer recurrence in the vas deferens are presented. These cases highlight the clinical importance of imaging the pattern of local prostate cancer recurrence and the potential difficulties that arise due to the altered anatomy in the prostate bed after prostatectomy or radiotherapy.

68Ga-PSMA PET/CT has become a well-established imaging modality to detect prostate cancer (PCa) metastases in biochemical recurrence. Despite its claimed specificity for PCa, 68Ga-PSMA uptake in tissues unrelated to PCa, particularly in the neovascular tissue of other cancers, has been reported in numerous studies. A 73-year-old man underwent 68Ga-PSMA PET/CT for biochemical recurrence of PCa 7 years after radical prostatectomy. The 68Ga-PSMA PET/CT showed 1 lesion with PSMA uptake in the distal left ureter. Histology revealed a low-grade noninvasive papillary urothelial carcinoma. By immunohistochemistry, PSMA expression ...

Most prostate cancers (PC) overexpress the ERG oncogene and karyopherin α 2 (KPNA2). These genes play a role in prostatic carcinogenesis, but their prognostic significance is still debated. The aim of this study was to determine the prognostic significance of ERG and KPNA2 expression, and their association to early prostate-specific antigen (PSA) biochemical recurrence in advanced PC with lymph node metastases. A series of 65 consecutive pN1 M0 R0 PC samples obtained by radical prostatectomy with lymphadenectomy has been analyzed for ERG and KPNA2 expression by immunohistochemistry. For each case, the following clini...

Authors: Bratu OG, Diaconu CC, Mischianu DLD, Constantin T, Stanescu AMA, Bungau SG, Ionita-Radu F, Marcu RD Abstract Prostate cancer is the second most common form of cancer in men in Europe. The primary treatment of this type of cancer is radical prostatectomy, which has shown good oncological results. Radical prostatectomy (open, laparoscopic or robotic) has high success and low morbidity rates in patients with localized prostate cancer. The life expectancy is>10 years after radical prostatectomy. Studies have shown that ~20%-30% of the patients who have undergone radical prostatectomy can develop biochemical...
