Diagnostic Ureteroscopy in CT Urography-Diagnosed Upper Tract Urothelial Carcinoma: Delay in Definitive Treatment and Increased Intravesical Recurrence.

Purpose To investigate the effect of diagnostic ureteroscopy (URS) on the delay to surgical treatment of upper tract urothelial carcinoma (UTUC) detected by imaging and the risk of intravesical recurrence. Materials and methods We undertook a retrospective case-note analysis of all patients who underwent radical nephroureterectomy (NUU) from November 2012 to July 2019. We identified those who underwent diagnostic ureteroscopy prior to NUU as Group 1 and those who did not undergo diagnostic URS as Group 2.

Accelerated methotrexate, vinblastine, doxorubicin, and cisplatin (AMVAC) as neoadjuvant chemotherapy for patients with muscle-invasive transitional cell carcinoma of the bladder.

Background: Meta-analysis data demonstrate a 5% absolute survival benefit for neoadjuvant chemotherapy (NAC) using cisplatin-based combination regimens in the radical treatment of muscle-invasive bladder cancer (MIBC). However, there are no randomized, controlled trial data on the optimum regimen. Accelerated methotrexate, vinblastine, doxorubicin, and cisplatin (AMVAC) is a dose-intense regimen that has the potential to minimize delays to definitive, potentially curative therapy.

Radiotherapy in localized bladder cancer: what is the evidence?

Purpose Of Review: Bladder-sparing bladder treatments have recently been rejuvenated with the introduction of concomitant chemotherapy usually as part of multimodality therapy including endoscopic resection and radiotherapy. This article reviews recent evidence for the role of radiotherapy in the treatment of localized bladder cancer.

Recent Findings: Several single institution series of multimodality radiochemotherapy have shown consistently fair disease-specific survival and local control in those who show a complete response after endoscopic resection.

Outcomes from Gleason 7, intermediate risk, localized prostate cancer treated with Iodine-125 monotherapy over 10 years.

Background And Purpose: The effect of predominating Gleason grade (3+4 versus 4+3) in Gleason sum score (GS) 7 prostate cancer (PCa) on brachytherapy outcomes is unclear. The 10 year experience of permanent brachytherapy monotherapy at a single UK centre for GS 7, intermediate risk (Memorial Sloan-Kettering model), PSA < or = 10 ng/ml, localised PCa is reported.

Materials And Methods: Between 1995 and 2004, the outcomes of 187 patients with GS 7 PCa (PSA < or = 10 ng/ml) were analysed from a cohort of 1298 men treated with permanent Iodine-125 prostate brachytherapy, including PSA relapse-free survival (PSA-RFS).

A 10-year retrospective review of a nonrandomized cohort of 458 patients undergoing radical radiotherapy or cystectomy in Yorkshire, UK.

Purpose: We have previously reported on the mortality, morbidity, and 5-year survival of 458 patients who underwent radical radiotherapy or surgery for invasive bladder cancer in Yorkshire from 1993 to 1996. We aim to present the 10-year outcomes of these patients and to reassess factors predicting survival.

Methods And Materials: The Northern and Yorkshire Cancer Registry identified 458 patients whose cases were subjected to Kaplan-Meier all-cause survival analyses, and a retrospective casenote analysis was undertaken on 398 (87%) for univariate and multivariate Cox proportional hazards modeling.

Fulguration of the lumen does not improve vasectomy sterilization rates.

Objectives: To assess the effect of adding lumen diathermy fulguration to our standard technique of vas ligation with polyglactin 910 (Vicryl(TM), Ethicon, Sommerville, NJ, USA) excision and fascial interposition, in an attempt to improve our sterilization rates. We previously reported the effect of changing suture material on vasectomy success rates; 3005 post-vasectomy semen analyses (PVSA) revealed a decrease in sterilization rates after surgery on changing from chromic catgut to polyglactin 910.

Patients And Methods: We retrospectively reviewed PVSA undertaken for vasectomies performed by urological surgeons at the Mid-Yorkshire NHS Trust for 18 months from September 2005 to February 2007.

Y-V preputioplasty for adult phimosis: a review of 89 cases.

Objectives: Numerous surgical techniques have been proposed for preputial relief to avoid circumcision. We aimed to review the indications, techniques, and outcomes of Y-V preputioplasty for men with phimosis treated at our institution between 1995 and the present.

Methods: We retrospectively examined the case notes of 89 patients who underwent Y-V preputioplasty since 1995.

Urinary biomarker profiling in transitional cell carcinoma.

Urinary biomarkers or profiles that allow noninvasive detection of recurrent transitional cell carcinoma (TCC) of the bladder are urgently needed. We obtained duplicate proteomic (SELDI) profiles from 227 subjects (118 TCC, 77 healthy controls and 32 controls with benign urological conditions) and used linear mixed effects models to identify peaks that are differentially expressed between TCC and controls and within TCC subgroups. A Random Forest classifier was trained on 130 profiles to develop an algorithm to predict the presence of TCC in a randomly selected initial test set (n = 54) and an independent validation set (n = 43) several months later.

Proteomic profiling of urinary proteins in renal cancer by surface enhanced laser desorption ionization and neural-network analysis: identification of key issues affecting potential clinical utility.

Recent advances in proteomic profiling technologies, such as surface enhanced laser desorption ionization mass spectrometry, have allowed preliminary profiling and identification of tumor markers in biological fluids in several cancer types and establishment of clinically useful diagnostic computational models. There are currently no routinely used circulating tumor markers for renal cancer, which is often detected incidentally and is frequently advanced at the time of presentation with over half of patients having local or distant tumor spread. We have investigated the clinical utility of surface enhanced laser desorption ionization profiling of urine samples in conjunction with neural-network analysis to either detect renal cancer or to identify proteins of potential use as markers, using samples from a total of 218 individuals, and examined critical technical factors affecting the potential utility of this approach.

Fibroblast growth factors and their receptors in transitional cell carcinoma.

Purpose: The recent identification in transitional cell carcinoma of mutations in a fibroblast growth factor (FGF) receptor, namely FGF receptor-3, has provoked great interest in the potential usefulness of FGF receptors and their ligands as molecular markers and as targets for bladder cancer therapy. We examined these possibilities in light of the published literature.

Materials And Methods: We reviewed the world literature on FGFs and their receptors from 1966 to January 2002 using PubMed.
