Urinary Metabolic Signatures Detect Recurrences in Non-Muscle Invasive Bladder Cancer

2019

Patients with non-muscle invasive bladder cancer (NMIBC) undergo lifelong monitoring based on repeated cystoscopy and urinary cytology due to the high recurrence rate of this tumor. Nevertheless, these techniques have some drawbacks, namely, low accuracy in detection of low-grade tumors, omission of pre-neoplastic lesions and carcinomas in situ (CIS), invasiveness, and high costs. This work aims to identify a urinary metabolomic signature of recurrence by proton Nuclear Magnetic Resonance (1H NMR) spectroscopy for the follow-up of NMIBC patients. To do this, changes in the urinary metabolome before and after transurethral resection (TUR) of tumors are analyzed and a Partial Least Square Dis…

Cigarette Smoking Status at Diagnosis and Recurrence in Intermediate-risk Nonemuscle-invasive Bladder Carcinoma

2013

Objective To study the effect of smoking status at diagnosis on recurrence in intermediate-risk non–muscle-invasive bladder carcinoma treated by transurethral resection (TUR) of the bladder and early intravesical chemotherapy. Methods Tumor characteristics and smoking status were recorded in 395 patients entered in a randomized multicenter trial comparing 2 different schedules of early intravesical chemotherapy. All patients received intravesical epirubicin (80 mg/50 mL) within 6 hours after TUR, followed by 5 more weekly instillations with (arm B) or without (arm A) monthly instillations for 1 year. Smoking habit was investigated at diagnosis through a structured questionnaire. Multivariat…

Are referral centers for non-muscle invasive bladder cancer compliant to EAU guidelines? A report from the vesical antiblastic therapy Italian study

2011

<i>Introduction:</i> Adherence to international guidelines is viewed as a prerequisite for optimal medical care delivery. Previously reported surveys for non-muscle-invasive bladder cancer (NMIBC) employed mailed questionnaires to urologists or patients resulting in conflicting degrees of agreement with existing guidelines. In the current study, contemporary information on the management of NMIBC was generated from a sample of Italian centers. <i>Patients and Methods:</i> Eight Italian referral centers for the treatment of NMIBC were asked to collect information relative to all consecutive patients with a histology-proven NMIBC undergoing a transurethral resection fr…

Does the Compliance to Intravesical BCG Differ between Common Clinical Practice and International Multicentric Trials?

2015

<b><i>Introduction:</i></b> The aim of this study was to analyze the reasons for intravesical BCG interruption in clinical practice. BCG for at least one year is advocated as the best regimen to treat high-risk non-muscle invasive bladder cancer (NMIBC). However, almost 50% of patients don't complete it. Toxicity accounts for 10% of dropouts in international trials. <b><i>Materials and Methods:</i></b> Patients with T1HG NMIBC undergoing 1-year BCG were enrolled in this study. BCG was administered for one year. Toxicity and causes of treatment interruption were recorded. <b><i>Results:</i></b> A total of 411 patients we…

TUR and Adjuvant Intravesical Chemotherapy in T1G3 Bladder Tumors: Recurrence, Progression and Survival in 137 Selected Patients Followed Up to 20 Ye…

2003

Abstract OBJECTIVES: To evaluate a highly selected population of patients affected by T1G3 bladder transitional cell carcinoma (TCCB) treated by transurethral resection (TUR) and adjuvant intravesical chemotherapy. MATERIALS AND METHODS: Between January 1976 and April 1999, 137 patients with T1G3 TCCB were treated by TUR plus intravesical chemotherapy. Particularly, a sequential combination of mitomycin C (MMC) and epirubicin (EPI) was adopted in 91 patients (66.4%). The main exclusion criteria were concomitant or previous Tis, previous T1G3 TCCB, tumor size greater than 3 centimeters and number of tumors more than 3. TUR was repeated if a superficial tumor recurred. Patients went off study…

PATIENT’S COMPLIANCE TO BCG. DO WE ADEQUATELY CONSIDER IT?

2014

Introduction: Several studies and meta-analysis demonstrated that BCG is the best treatment for conservative management of high-risk NMI-BC with a net benefit in terms of both recurrence-free and progression-free survival (1, 2). Maintenance lasting minimum one year is recommended. In spite of the effectiveness, the amount of patients who complete the manteinance schedule does not exceed 50% (3). The reasons of BCG maintenance interruption remain still unclear. The aim of our study was to investigate the causes of low adherence to 1-year full dose maintenance BCG in a large series. Patients and Methods: The clinical files of consecutive patients affected by T1 HG NMI-BC and undergoing adjuv…

THE ROLE OF PERI-OPERATIVE BLOOD TRANSFUSION ON CANCER SPECIFIC AND OVERALL MORTALITY AFTER RADICAL CYSTECTOMY FOR BLADDER CANCER

2014

Only few studies investigated the impact of the peri-operative blood transfusion (PBT) rate on both cancerspecific (CSM) and overall mortality (OM) after radical cystectomy (RC) for bladder cancer (Bca). To date, no study has taken into account the possible prognostic role of the pre-operative hemoglobin level (Hb). The aim of this study was to evaluate the impact of both pre-operative Hb level and PBT rate on CSS and OS of patients who underwent RC. Materiali e metodi The study cohort included 1575 patients treated with RC for BCa between 1990 and 2012 at a single tertiary referral center. Complete clinical, pathological and follow up-data was available for all the patients. Kaplan- Meier …

Risk factors for residual disease at re-TUR in a large cohort of T1G3 patients

2021

Item does not contain fulltext Introduction and objectives: The goals of transurethral resection of a bladder tumor (TUR) are to completely resect the lesions and to make a correct diagnosis in order to adequately stage the patient. It is well known that the presence of detrusor muscle in the specimen is a prerequisite to minimize the risk of under staging. Persistent disease after resection of bladder tumors is not uncommon and is the reason why the European Guidelines recommended a re-TUR for all T1 tumors. It was recently published that when there is muscle in the specimen, re-TUR does not influence progression or cancer specific survival. We present here the patient and tumor factors th…
