CORSO Carcinoma vescicale non muscolo invasivo : qualità del trattamento endoscopico

Sebbene la resezione endoscopica per via transuretrale (TURBT) rappresenti lo standard per la diagnosi, la stadiazione e il primo trattamento delle neoplasie vescicali, la sua efficacia rimane ad oggi limitata a causa di numerose limitazioni intrinseche alla stessa procedura. I principali limiti oncologici della TURBT sono rappresentati da – violazione della asportazione en bloc della neoplasia, -inefficacia nei confronti delle lesioni piatte o non riconoscibile endoscopicamente, -incompletezza della resezione. Anche la qualità della esecuzione tecnica della resezione, in mancanza di adeguati standard e programmi di insegnamento è ridotta in moltissimi contesti clinici. Di conseguenza, la T…

Postoperative nomogram for invasive bladder cancer: does it really work? A multicenter cohort study.

Objectives: Nomograms are statistical models designed to maximize predictive accuracy. We have tested the statistical correlation between the predictions of International Bladder Cancer Nomogram Consortium and the clinical outcomes in a multicenter Italian cohort of patients treated with radical cystectomy (RC) and pelvic lymph-nodes dissection. Methods and materials: Two hundred four patients who underwent RC were selected for multiple variable and then enrolled in the study. Patients were tested by the "online tool" based on the nomogram, then stratified and risk grouped for 5-year predicted disease-free survival (pDFS): low risk (67%-100%), intermediate risk (34%-66%), and high risk grou…

Prognostic factors and risk groups in T1G3 patients initially treated with BCG: Results of a multicenter retrospective series in 1743 patients

Introduction and Objectives: The impact of prognostic factors in T1G3 patients (pts) is critical for proper treatment decision making, however most available data are from small series of pts. The aim of the current study is to assess prognostic factors in a large group of pts who received BCG as initial treatment of T1G3 tumours and identify a subgroup of high risk pts who should be considered for early cystectomy. Patients and Methods: Individual pt data were collected for 1743 ptsfrom 20 centers who received induction or maintenance BCG between 1990 and 2008. Using Cox regression analysis, the prognostic importance of the following variables were assessed for time to recurrence, progress…

THE IMPACT OF RE-TUR ON CLINICAL OUTCOMES IN A LARGE COHORT OF T1G3 PATIENTS TREATED WITH BCG.

Scopo del lavoro Re-TUR is strongly advocated for T1G3, because of the high incidence residual disease and mainly the risk of substaging. Its real clinical value remains to be determined and the clinical factors that may influence the decision. Some authors suggest that when muscle is present in the specimen, re-TUR may be avoided. To evaluate if the presence of muscle or not at the first TUR in T1G3 bladder cancer makes a difference in recurrence, progression and cancer specific survival after re-TUR. Materiali e metodi In a large retrospective cohort of 2530 primary T1G3 initially treated with BCG, 953 (37.7%) had a re-TUR. According to the presence or not of muscle in the specimen of pri…

Analisi delle varianti rare del carcinoma a cellule uroteliali della vescica nei Pazienti sottoposti a cistectomia radicale: impatto sulla prognosi.

Determination of organophosphorus pesticides in honeybees after solid-phase microextraction.

A method based on solid-phase microextraction (SPME) followed by gas chromatography with nitrogen-phosphorus detection was developed for the purpose of determining 18 organophosphorus pesticide residues in honeybee samples (Apis mellifera). The extraction capacities of polyacrylate and poly(dimethylsiloxane) fibers were compared. The main factors affecting the SPME process, such as the absorption time profile, salt, and temperature, were optimized. The method involved honeybee sample homogenization, elution with an acetone:water solution (1:1) and dilution in water prior to fiber extraction. Moreover, the matrix effect on the extraction was evaluated. In samples spiked at the 0.2 mg kg(-1) …

Open Question in UrologiaIl Tumore vescicale non muscolo-invasivo

Open Questions in Practical Urology (OpenQ) è un’iniziativa formativa nata spontaneamente durante il congresso EAU del 2008 dal suggerimento di alcuni giovani urologi e specializzandi intervenuti in una nostra discussione relativamente alle attese che ciascuno di noi ha nel partecipare ai convegni scientifici. L’osservazione più comune è stata che spesso ci si trova ad ascoltare relazioni di alto contenuto scientifico in un contesto in cui non è facile intervenire con domande semplici, dirette e di immediato impatto pratico. Limite questo particolarmente vero per i colleghi più giovani che, in parte per timidezza e in parte per il tempo limitato dedicato alla discussione, non riescono a pre…
