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…
A new preprocessing tool of ECMWF data for CALMET forecasting simulations
2019
Today, strategies for emergency preparedness, in presence of accidental scenarios in high-risk plants with releases into the atmosphere, have become a priority. To achieve this goal, it is important to have forecast meteorological data in local areas to use in dispersion and transport models and so to respond in advance emergency situations. The paper reports results of research performed to develop a new tool, called FORCALM that is capable to elaborate European Centre for Medium-Range Forecasts (ECMWF) forecast data to use for simulations by CALMET/CALPUFF modeling system. A case study, relevant to an accident occurred in Mediterranean Refinery at Milazzo (Italy), has been examined to val…
Definizione della metodologia e degli input necessari per l’esecuzione di analisi integrate CALMET-CALPUFF ai fini della valutazione della dispersion…
2015
Il presente documento riporta l’attività condotta durante l’ultima annualità dell’AdP ENEAMSE, linea progettuale LP1: “Sviluppo competenze scientifiche nel campo della sicurezza nucleare”, Task B2.3 “Definizione della metodologia e degli inputs necessari per l’esecuzione di analisi integrate Calmet-Calpuff ai fini della valutazione della dispersione di inquinanti radioattivi in atmosfera”. La linea di ricerca si inserisce nell’ambito degli studi condotti dall’ENEA a supporto delle attività di pre-emergenza a seguito di situazioni incidentali in uno degli impianti nucleari dislocati nei Paesi frontalieri dell'Italia.
Analisi dei modelli validi per lo studio dei processi di deposizione secca e sui dati meteo previsionali dell’ECMWF
2017
The DEIM's research group in collaboration with ENEA –C.R. Bologna, has performed the following activities: "Analysis of models to study dry deposition processes of pollutants in atmosphere onto urban surface", and "Preliminary study of compatibility between ECMWF forecast data and CALMET model". Regarding the first activity, a dry deposition model, based on electrical analogy, is developed to analyze complex phenomena,such as inertial impact processes and wind turbulence effects, that influence the transport of pollutants in the interface between urban canopy and quasi-laminar sublayer. The model allows the deposition rate assessment for particles with different diameters and various atmos…
Interleukin-17-positive mast cells influence outcomes from BCG for patients with CIS: Data from a comprehensive characterisation of the immune microe…
2017
The tumour immune microenvironment is considered to influence cancer behaviour and outcome. Using a panel of markers for innate and adaptive immune cells we set out to characterise and understand the bladder tumour microenvironment of 114 patients from a prospective multicentre cohort of newly-diagnosed bladder cancer patients, followed-up for 4.33±1.71 years. We found IL-17-positive cells were significantly increased in primary and concomitant carcinoma in situ (CIS), p<0.0001, a highly malignant lesion which is the most significant single risk factor for disease progression. Further characterisation of the tumour immunophenotype identified IL-17+ cells as predominantly mast cells rather t…
Trattamento endovescicale alternativo al BCG nel carcinoma vescicale NMI a rischio intermedio o elevato
2013
Endovesical treatment as an alternative to BCG for intermediate or high-risk NMI bladder cancer A shortage of BCG is foreseen till the end of 2013. Which will be the management of intermediate and high-risk NMI-BC if BCG will not be available? In patients harboring high-risk NMI tumors, particularly T1G3 and Tis, the first therapeutic choice is radical cystectomy. Device-assisted therapies, although showing promising results, should be considered only for selected patients. In intermediate risk patients, intravesical chemotherapy remains a legitimate option even if BCG is available. Thus, in a period of BCG shortage, intravesical chemotherapy should be offered, preferably preceded by early …
Phenotypical and functional analysis of memory and effector human CD8 T cells specific for mycobacterial antigens
2006
Abstract Mycobacterium tuberculosis infects one-third of the global population and claims two million lives every year. Because memory CD8 T cells exhibit a high heterogeneity in terms of phenotype and functional characteristic, we investigated the frequency, phenotype, and functional properties of Ag85A epitope-specific HLA-A*0201 CD8 T cells in children affected by tuberculosis (TB) before and 4 mo after chemotherapy and healthy contact children. Using Ag85A peptide/HLA-A*0201 pentamer, we found a low frequency of blood peptide-specific CD8 T cells in tuberculous children before therapy, which consistently increased after therapy to levels detected in healthy contacts. Ex vivo analysis of…
The Factors Affecting Expansion of Reactive Tumor Infiltrating Lymphocytes (TIL) From Bladder Cancer and Potential Therapeutic Applications
2021
Tumor infiltrating lymphocytes (TIL) therapy was shown to provide durable objective response in patients with metastatic melanoma. As a fundamental first step to bring TIL therapy to clinical use, identification of patients whose tumors yield optimal numbers of reactive TIL is indispensable. We have previously shown that expansion of tumor reactive TIL from primary bladder tumors and lymph node metastases is feasible. Here, we performed TIL harvesting from additional surgical specimens (additional 31 primary tumors and 10 lymph nodes) to generate a heterogenous cohort of 53 patients with bladder cancer (BC) to evaluate the tumor characteristics that lead to tumor-reactive TIL expansion. Amo…
Although rare, severe complications following intravesical bacillus Calmette-Guerin treatment should not be overlooked!

An interesting series of 22 patients affected by severe systemic toxicity following bacillus Calmette-Guerin (BCG) intravesical adjuvant therapy for bladder cancer is presented in this issue of Inf...
Prognostic factors and risk groups in T1G3 non-muscle-invasive bladder cancer patients initially treated with Bacillus Calmette-Guérin: results of a …
2014
Contains fulltext : 153742.pdf (Publisher’s version ) (Closed access) BACKGROUND: The impact of prognostic factors in T1G3 non-muscle-invasive bladder cancer (BCa) patients is critical for proper treatment decision making. OBJECTIVE: To assess prognostic factors in patients who received bacillus Calmette-Guerin (BCG) as initial intravesical treatment of T1G3 tumors and to identify a subgroup of high-risk patients who should be considered for more aggressive treatment. DESIGN, SETTING, AND PARTICIPANTS: Individual patient data were collected for 2451 T1G3 patients from 23 centers who received BCG between 1990 and 2011. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Using Cox multivariable re…
