ABSTRACT Bladder cancer is the fourth most common cancer in the United States. Urothelial carcinoma that originates from the urinary bladder is the most common subtype. These NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) provide recommendations on the diagnosis and management of non-muscle-invasive and muscle-invasive urothelial carcinoma of the bladder. This version of the guidelines provides extensive reorganization and updates on the principles of chemotherapy management.

    ABSTRACT: Bladder cancer exhibits a broad spectrum of heterogenous clinical behavior. Conventionally used clinicopathological factors are associated with certain limitations regarding the accurate prediction of outcome. Recent studies have focused on the predictive role of cellular regulatory markers. The present case aimed to describe an extremely rare case of non-muscle invasive bladder cancer (NMIBC) patient with early isolated bone metastases following curative surgery. An assessment of the alterations of cellular regulatory biomarkers using immunohistochemistry was performed and a review of previous literatures is presented. It is very unusual feature that the patients with NMIBC who developed bone metastases without regional lymph node metastasis or local invasion. The patient had a solitary, high-grade T1 tumor which was not associated with carcinoma in situ and microscopic lymphovascular invasion. However, it had rapidly metastasized to distant sites following definitive surgery and exclusively limited to bones. Of special interest appears that altered expressions of combined cellular biomarkers including p53, Ki-67, and epidermal growth factor receptor were not observed focally, but rather diffusely and intensively throughout the tumor tissue. As an accurate prediction of outcome in patient with bladder cancer is currently limited, individual targeted approach based on pathological biomarkers may be helpful to determining what treatments are best or when the optimal time is.

    ABSTRACT: To summary the procedure and experience of a novel surgical management for male infertility secondary to midline prostatic cyst (MPC). From February 2012 to February 2014, 12 patients were diagnosed with PMC by semen analysis, seminal plasma biochemical analysis, transrectal ultrasonography (TRUS), and pelvic magnetic resonance imaging (MRI). All patients underwent the transurethral unroofing of MPC using resectoscope, the dilation of ejaculatory duct, and the irrigation of seminal vesicle using seminal vesiculoscope. All patients were followed up at least 3 months after operation. Preoperative semen analyses of 12 patients showed oligoasthenozoospermia (5/12) or azoospermia (7/12), low semen volume (0-1.9 mL), and low pH level (5.5-7.0). Preoperative seminal plasma biochemical analyses showed reduced semen fructose. TURS and MRI revealed a cyst lesion located in the midline of prostatic. After 3 months follow up, the semen quality of 80% patients (4/5) with oligoasthenozoospermia improved obviously. The spermatozoa were present in the semen in 5 of 7 cases with azoospermia. In one patient, the spermatozoa occurred in the urine after ejaculation. Surgical management using transurethral resectoscopy and seminal vesiculoscopy is effective, minimally invasive, and safe for male infertility secondary to MPC.

    ABSTRACT: Objectives. To investigate the prognostic factors for bladder recurrence after radical nephroureterectomy (RNU) in patients with upper urinary tract urothelial carcinoma (UUT-UC). Methods. From 1994 to 2012, 695 patients with UUT-UC treated with RNU were enrolled in National Taiwan University Medical Center. Among them, 532 patients with no prior bladder UC history were recruited for analysis. We assessed the impact of potentially prognostic factors on bladder recurrence after RNU. Results. The median follow-up period was 47.8 months. In the Cox model, ureteral involvement and diabetes mellitus (DM) were significantly associated with a higher bladder recurrence rate in the multivariate analysis (hazard ratio [HR]: 1.838; P = 0.003 and HR: 1.821; P = 0.010, resp.). In the Kaplan-Meier analysis, DM patients with concomitant ureteral UC experienced about a threefold increased risk of bladder recurrence as compared to those without both factors (HR: 3.222; P < 0.001). Patients with either of the two risk factors experienced about a twofold increased risk as compared to those without both factors (with DM, HR: 2.184, P = 0.024; with ureteral involvement, HR: 2.006, P = 0.003). Conclusions. Ureteral involvement and DM are significantly related to bladder recurrence after RNU in patients with UUT-UC.
