Purpose: There is a lack of data on true long-term functional outcome of orthotopic bladder substitution. The primary study objective was to report our 35-year clinical experience.

Materials And Methods: Since October 1985, 259 male patients from a large single center radical cystectomy series with complete followup of more than 60 months (median 121, range 60-267) without recurrence, irradiation or undiversion that might have affected the functional outcome, were included.

Background: The extent of lymph node dissection (LND) in bladder cancer (BCa) patients at the time of radical cystectomy may affect oncologic outcome.

Objective: To evaluate whether extended versus limited LND prolongs recurrence-free survival (RFS).

Design, Setting, And Participants: Prospective, multicenter, phase-III trial patients with locally resectable T1G3 or muscle-invasive urothelial BCa (T2-T4aM0).

Acute scrotal pain in childhood is an emergency.Sudden scrotal pain may be caused by a variety of diseases. Therefore, it is important to carefully consider the specific medical history and possible differential diagnoses in each case for fast and decisive action (e.

Objectives: To identify which patients with macroscopic bladder-infiltrating T4 prostate cancer (PCa) might have favourable outcomes when treated with radical cystectomy (RC).

Materials And Methods: We evaluated 62 patients with cT4cN0-1 cM0 PCa treated with RC and pelvic lymph node dissection between 1972 and 2011. In addition to descriptive statistics, the Kaplan-Meier method and log-rank tests were used to depict survival rates.

Background: No data exist on the patterns of biochemical recurrence (BCR) and their effect on survival in patients with high-risk prostate cancer (PCa) treated with surgery. The aim of our investigation was to evaluate the natural history of PCa in patients treated with radical prostatectomy (RP) alone.

Materials And Methods: Overall, 2,065 patients with high-risk PCa treated with RP at 7 tertiary referral centers between 1991 and 2011 were identified.

Background: Pretreatment tables for the prediction of pathologic stage have been published and validated for localized prostate cancer (PCa). No such tables are available for locally advanced (cT3a) PCa.

Objective: To construct tables predicting pathologic outcome after radical prostatectomy (RP) for patients with cT3a PCa with the aim to help guide treatment decisions in clinical practice.

Background: High-risk prostate cancer (PCa) is an extremely heterogeneous disease. A clear definition of prognostic subgroups is mandatory.

Objective: To develop a pretreatment prognostic model for PCa-specific survival (PCSS) in high-risk PCa based on combinations of unfavorable risk factors.

Background: The current role of radical prostatectomy (RP) in patients with high-risk disease remains controversial.

Objective: To identify which high-risk prostate cancer (PCa) patients might have favorable pathologic outcomes when surgically treated.

Design, Setting, And Participants: We evaluated 1366 patients with high-risk PCa (ie, at least one of the following risk factors: prostate-specific antigen [PSA]>20 ng/ml, cT3, biopsy Gleason 8-10) treated with RP and pelvic lymph node dissection (PLND) at eight European centers between 1987 and 2009.

Objective: • To assess the feasibility of radical prostatectomy (RP) in a series of patients with prostate cancer with very high prostate-specific antigen (PSA) levels by comparing the clinical outcomes of different PSA thresholds (20.1-50 ng/mL, 50.1-100 ng/mL and >100 ng/mL, respectively).

Background: Prostate cancer (PCa) patients with pretreatment prostate-specific antigen (PSA) >20 ng/ml have a high risk of biochemical and clinical failure and even cancer-related death after local therapy. Pretreatment predictors of outcome after radical prostatectomy (RP) in this patient group are necessary.

Objective: Our aim was to assess how the use of additional high-risk factors (biopsy Gleason score [bGS] > or = 8 or clinical stage 3-4) can improve prediction of treatment failure and cancer-related death after RP in patients with PSA >20.

Purpose: To present the long-term outcome of high-risk prostate cancer patients treated by radical retropubic prostatectomy (RRP) and stage-dependent adjuvant androgen deprivation therapy.

Patients And Methods: Between 1989 and 2005, 2,655 patients underwent RRP by 9 surgeons. All cases (n = 372) with high-risk prostate cancer (serum PSA >20 ng/ml, and/or clinical stage T2c or greater, and/or biopsy Gleason score 8 or greater) were identified and analyzed retrospectively.

Purpose: Radical cystectomy as standard treatment of muscle-invasive urothelial carcinoma of the urinary bladder cures less than 50% of patients with locally advanced bladder cancer. We compared two adjuvant combination chemotherapies in patients with stage pT3a-4a and/or pathologic node-positive transitional-cell carcinoma of the bladder after radical cystectomy.

Patients And Methods: A total of 327 patients were randomly assigned to either adjuvant systemic chemotherapy with three cycles of cisplatin 70 mg/qm(2) on day 1 and methotrexate 40 mg/qm(2) on days 8 and 15 of a 21-day cycle (CM) or three cycles of methotrexate 30 mg/qm(2) on days 1, 15, and 22, vinblastine 3 mg/qm(2) on days 2, 15, and 22, epirubicin 45 mg/qm(2) on day 2, and cisplatin 70 mg/qm(2) on day 2 of a 28-day cycle (M-VEC).
