BACKGROUND: The immune escape or tolerance of cancer cells is considered to be closely involved in cancer progression. Programmed death-1 (PD-1) is an inhibitory receptor expressed on activating T cells, and several types of cancer cells were found to express PD-1 ligand 1 (PD-L1) and ligand 2 (PD-L2). METHODS: In the present study, we investigated PD-L1/2 expression in papillary renal cell carcinoma (pRCC). RESULT: We found PD-L1 expression in 29 of 102 cases, but no PD-L2 expression was seen...

BACKGROUND: The goal was to assess the natural history and management of patients with pathologically proven bilateral (synchronous) RO after undergoing initial partial nephrectomy (PN). METHODS: All patients underwent either robotic/laparoscopic or open PN by two experienced genitourinary oncologists from 2005-2013. Final pathology was determined by surgical excision, CT-guided percutaneous core biopsy (CT-biopsy) or fine needle aspiration (FNA). Patient demographics, tumor characteristics (pathologic data, location, size) type of surgery, pre/post estimated glomerular filtration rate (eGFR) and surgical complications were recorded...

BACKGROUND: Stone retropulsion represents a challenge for intracorporeal lithotripsy of ureteral calculi. The consequences are an increased duration and cost of surgery as well as decreased stone-free rates. The use of additional tools to prevent proximal stone migration entails further costs and risks for ureteral injuries. We present the simple technique of using a coil of the routinely used guidewire to prevent stone retropulsion. METHODS: We retrospectively evaluated all patients with mid-to-proximal ureteral stones in 2014, which were treated by ureteroscopic lithotripsy (Ho: YAG and/or pneumatic lithotripsy)...

BACKGROUND: Immunotherapy with high-dose interleukin-2 (HD-IL2) results in long-term survival in some metastatic renal cell carcinoma (mRCC) patients but has significant acute toxicities. Biomarkers predicting response to therapy are needed to better select patients most likely to benefit. NLR (absolute neutrophil count (ANC)/absolute lymphocyte count (ALC)) is a prognostic and predicative biomarker in various malignancies. The goal was to determine whether NLR can predict response to HD-IL2 in this setting...

BACKGROUND: Lower urinary tract symptoms are highly prevalent and a large proportion of these symptoms are known to be associated with a dysfunction of the afferent pathways. Diagnostic tools for an objective and reproducible assessment of afferent nerve function of the lower urinary tract are missing. Previous studies showed first feasibility results of sensory evoked potential recordings following electrical stimulation of the lower urinary tract in healthy subjects and patients. Nevertheless, a refinement of the methodology is necessary...

BACKGROUND: Anxiety disorders (ADs) are common with a high rate of medical comorbidities. Although the association between ADs and the overall cancer risk remains controversial, patients with ADs were found to be more likely to develop specific cancer types. Herein, we estimated the risk of developing urological cancers among patients with ADs in a 5-year follow-up period using a population-based database. METHODS: Two study cohorts were identified from the Taiwan Longitudinal Health Insurance Database 2005: patients with ADs, and comparison subjects selected by one-to-one matching for sex, age, and the year of recruitment...

BACKGROUND: C-C chemokine receptor type 7 (CCR7) overexpression correlated with lymphatic metastasis and poor prognosis is a major obstacle to bladder cancer treatment. Recent studies have revealed that miR-199a-5p was significantly abnormal expressed in several solid tumors and functioned as oncogene or tumor suppressor. This study was aimed to further investigate the effects of miR-199a-5p on the cell metastasis mediated by CCR7 in bladder cancer. METHODS: Quantitative Real Time PCR (qRT-PCR) was firstly performed to identified the expression of miR-199a-5p and CCR7 in human bladder cancer samples and cell lines...

BACKGROUND: Up to a fifth of patients diagnosed with prostate cancer (PC) will develop castration-resistant prostate cancer (CRPC), which has been associated with a poor prognosis. The aim of this study was to consider the patient perspective as part of the overall treatment decision-making process for CRPC, given that an alignment between patient preference and prescribing has been shown to benefit patient outcomes. This study examines preferences of patients with CRPC in Japan for treatment features associated with treatments like RA-223, abiraterone, and docetaxel and to examine the extent to which treatment preferences may vary between symptomatic and asymptomatic patients...
