Patterns of Bladder Preservation Therapy Utilization for Muscle-Invasive Bladder Cancer
2016
Background: Trimodality bladder preservation therapy (BPT) in muscle invasive bladder cancer (MIBC) includes a maximal transurethral resection followed by concurrent chemoradiotherapy as an alternative to radical cystectomy (RC) in appropriately selected patients, or as a treatment option in non-cystectomy candidates. Several chemotherapy regimens can be used in BPT, but little is known about current practice patterns. Objective: To describe utilization patterns of BPT and associated survival outcomes in MIBC. Methods: Data were collected from the Retrospective International Study of Cancers of the Urothelial Tract (RISC), a database of 3,024 consecutive patients from 29 international acade…
Alpha-adrenergic drugs in retrograde ejaculation.
1974
6 men with complete or partial loss of ejaculation as a result of retroperitoneal lymphadenectomy (performed because of testicular tumor) were treated with an intravenous injection of 60 mg synephrine. Synephrine stimulates adrenergic alpha-receptors. Only 1 man with sustained retrograde ejaculation improved following treatment showing antegrade ejaculation. This temporary restoration of fertility was thought to be due to an increase in bladder neck tone and prevention of backflow of semen into the bladder as a result of stimulation of adrenergic alpha-receptors.
Long Term Results of Bladder Exstrophy
1999
After primary bladder closure or urinary diversion, other factors apart from the reconstruction gain importance for individuals with the exstrophy-epispadias complex: social integration and, after reaching puberty, sexuality and fertility.
Electrospun Polyhydroxyethyl-Aspartamide-Polylactic Acid Scaffold for Biliary Duct Repair: A Preliminary In Vivo Evaluation
2017
Abstract Tissue engineering has emerged as a new approach with the potential to overcome the limitations of traditional therapies. The objective of this study was to test whether our polymeric scaffold is able to resist the corrosive action of bile and to support a cell's infiltration and neoangiogenesis with the aim of using it as a biodegradable tissue substitute for serious bile duct injuries. In particular, a resorbable electrospun polyhydroxyethyl-aspartamide–polylactic acid (90 mol% PHEA, 10 mol% PLA)/polycaprolactone (50:50 w/w) plate scaffold was implanted into rabbit gallbladder to assess the in vivo effects of the lytic action of the bile on the scaffold structure and then as a tu…
Clinical use of BCG and its complications: a case series
2021
Bacillus Calmette-Guérin (BCG), a live, attenuated strain of Mycobacterium bovis, is the essential constituent of the vaccine against tuberculosis and the gold-standard adjuvant treatment for urothelial cancer of the bladder. Being a live, attenuated strain with a potential pathogenic action, bacilli can cause several complications, both locally near the inoculation site and remotely through blood dissemination. BCG-related disease can represent a side effect of anti-TB vaccination in patient with congenital or acquired immunodeficiency or a complication of the therapeutic schedule in oncologic patients. Herein we report five cases of BCG-related disease which occurred at the Infectious Dis…
FATTORI PROGNOSTICI NELL'EVOLUZIONE DEL REFLUSSO VESCICO-URETERALE IN ETA' PEDIATRICA
2002
Despite the large number of children with reflux, management among urologists is still controversial. One of the most debacted aspects is the choice between observation treatment or surgical treatment.
Research of prognostic biomarkers in Tunisian patients with bladder cancer
2016
Bladder cancer is the first most common urogenital cancer in men in Tunisia, with a high recurrence rate. Patients with muscle-invasive disease develop metastasis. The need for expensive continuous surveillance. In this thesis we try to search some candidate biomarkers. Their use for cancer staging and personalization of therapy at the time of diagnosis in order to identify a better treatment could improve patient care. The aim of this first part of our study was to investigate the clinical significance of three immune cell-related transcription factors, T-bet, GATA-3 and Bcl-6 in Tunisian patients with bladder cancer. We found that T-bet level was significantly higher in invasive carcinoma…
Visceral fat area as a new independent predictive factor of survival in patients with metastatic renal cell carcinoma treated with antiangiogenic age…
2011
Abstract Purpose. A better identification of patients who are more likely to benefit from vascular endothelial growth factor–targeted therapy is warranted in metastatic renal cell carcinoma (mRCC). As adipose tissue releases angiogenic factors, we determined whether parameters such as visceral fat area (VFA) were associated with outcome in these patients. Experimental Design. In 113 patients with mRCC who received antiangiogenic agents (bevacizumab, sunitinib, or sorafenib) (n = 64) or cytokines (n = 49) as first-line treatment, we used computed tomography to measure VFA and subcutaneous fat area (SFA). We evaluated associations linking body mass index (BMI), SFA, and VFA to time to progres…
Intravesical gemcitabine in superficial bladder tumors. Results of a phase I-II study
2004
the good tolerability of intravesical gemcitabine have been recently published. The evaluation of the activity on a papillary marker lesion is the best tool to measure the efficacy of a drug by intravesical route against superficial transitional cell carcinoma of the bladder (TCCB). The scientific background and the ethical acceptability of this approach have been validated by the European Organization for Research and Treatment of Cancer Urological Group. The aim of the present study was to evaluate the ablative efficacy of weekly intravesical instillations of gemcitabine against a histologically proven papillary marker lesion. MATERIAL & METHODS: Twenty-seven patients, affected by recurre…
The pathology of bladder cancer: An update on selected issues
2006
OBJECTIVE: To achieve a closer relationship between urologists and pathologists and to use a common language and identical objectives in the pathology of bladder cancer. METHODS AND RESULTS: Special emphasis was given to an analysis of the new World Health Organization (WHO) grading system, to the interpretation of the last Tumour-Nodes-Metastasis staging rules, and to identifying new markers of prognostic significance in clinical practice. A consensus was achieved on the main points. CONCLUSIONS: The 2004 WHO grading system must become acceptable to clinicians, perhaps by a minimal modification of the present terminology. Simple transurethral resection-biopsy should be expressed in terms o…
