Cellular senescence has been theorized to oppose neoplastic transformation triggered by activation of oncogenic pathways in vitro, but the relevance of senescence in vivo has not been established. The PTEN and p53 tumour suppressors are among the most commonly inactivated or mutated genes in human cancer including prostate cancer. Although they are(More)
PURPOSE Prostate-specific antigen (PSA) defined biochemical recurrence (BCR) of prostate cancer is widely used for reporting the outcome of radical prostatectomy (RP). A standardized BCR definition is lacking, and overall progression-free probability and risk of subsequent metastatic disease progression may vary greatly depending on the PSA criterion used.(More)
Complete inactivation of the PTEN tumor suppressor gene is extremely common in advanced cancer, including prostate cancer (CaP). However, one PTEN allele is already lost in the vast majority of CaPs at presentation. To determine the consequence of PTEN dose variations on cancer progression, we have generated by homologous recombination a hypomorphic Pten(More)
BACKGROUND The treatment for and long-term outcome of renal angiomyolipoma (AML) at high-risk for bleeding has not been determined. OBJECTIVE To evaluate the complication rates and the long-term outcomes among patients treated by selective arterial embolization (SAE) for a large or symptomatic renal AML. DESIGN, SETTING, AND PARTICIPANTS Forty-one(More)
PURPOSE We evaluated risk factors for positive soft tissue surgical margins and the impact of soft tissue surgical margins on metastatic progression and disease specific survival in patients treated with radical cystectomy for bladder cancer. MATERIALS AND METHODS A total of 1,589 patients who underwent radical cystectomy for primary urothelial cancer at(More)
PURPOSE A postoperative nomogram for prostate cancer recurrence after radical prostatectomy (RP) has been independently validated as accurate and discriminating. We have updated the nomogram by extending the predictions to 10 years after RP and have enabled the nomogram predictions to be adjusted for the disease-free interval that a patient has maintained(More)
PURPOSE Physicians often order periodic bone scans (BS) to check for metastases in patients with an increasing prostate-specific antigen (PSA; biochemical recurrence [BCR]) after radical prostatectomy (RP), but most scans are negative. We studied patient characteristics to build a predictive model for a positive scan. PATIENTS AND METHODS From our(More)
The purpose of this study was to assess the indwelling time and retrievability of the Optease IVC filter. Between 2002 and 2009, a total of 811 Optease filters were inserted: 382 for prophylaxis in multitrauma patients and 429 for patients with venous thromboembolic (VTE) disease. In 139 patients [97 men and 42 women; mean age, 36 (range, 17–82) years],(More)
PURPOSE Candidates for prostatectomy who require chronic anticoagulant therapy present a major perioperative management problem due to the threat of significant hemorrhage associated with surgery and the risk of thromboembolism associated with discontinuation of the anticoagulants. We evaluated prospectively a perioperative routine using low molecular(More)
PURPOSE We report our experience with laparoscopic partial nephrectomy for central tumors compared to peripheral tumors to analyze the feasibility and safety of the laparoscopic approach to these complex cases. MATERIALS AND METHODS Between October 2002 and July 2007, 212 patients underwent laparoscopic partial nephrectomy. In 53 patients the tumor was(More)
