The psychological distress and care needs of mesothelioma patients and asbestos-exposed subjects: A systematic review of published studies.

BACKGROUND: The purpose of this study is to present the results of a systematic review of published research that focuses on psychological aspects of malignant mesothelioma patients and asbestos-exposed people. METHODS: Our research includes primary studies published between 1980 and 2016, using information from the Cochrane Library, the Psychology Behavioral Sciences Collection, PsychINFO, PubMed, PubGet, PubPsych, and Scopus, in compliance with PRISMA guidelines. RESULTS: We identified 12 papers that investigated the psychological distress and care needs of mesothelioma patients, and nine papers for asbestos-exposed subjects. CONCLUSIONS: This paper highlights the paucity of studies on the psychological distress and care needs of mesothelioma patients and asbestos-exposed subjects. It confirms that malignant mesothelioma is associated with the physical, emotional, and social functioning of patients, while also suggesting that the risk of developing asbestos-related diseases among asbestos-exposed subjects is associated with high levels of psychological distress, despair, and mental health difficulties.

[National epidemiological surveillance systems of mesothelioma cases]. / I sistemi nazionali di sorveglianza dei casi di mesotelioma.

INTRODUZIONE: sebbene la relazione causale tra esposizione ad amianto e malattie neoplastiche sia ben nota, in molti Paesi il consumo del materiale è ancora rilevante e crescente. A causa della lunga latenza, nei Paesi dove è stato bandito (come in Italia) è oggi in corso un'epidemia di malattie correlate ad amianto. OBIETTIVI: descrivere i sistemi di sorveglianza dei mesoteliomi attivi nel mondo mediante un'analisi comparativa. METODI: è stata condotta una revisione bibliografica della letteratura disponibile sui sistemi di sorveglianza epidemiologica dei mesoteliomi attivi nel mondo, comparando metodi e risultati disponibili. RISULTATI: sistemi di ricerca dei casi incidenti e di analisi anamnestica dei soggetti ammalati sono attivi solo in Italia, Francia e Corea del Sud. I Paesi presso i quali sono attivi sistemi di rilevazione e controllo dei casi incidenti di mesotelioma sono quelli in cui vige il bando dell'amianto e che hanno sperimentato consumi rilevanti in passato. Non sono stati istituiti sistemi epidemiologici di sorveglianza in molti Paesi dove il consumo di amianto è ancora importante (inclusi Russia, Cina, India e Brasile). CONCLUSIONI: si conferma l'importanza dei sistemi di sorveglianza epidemiologica dei mesoteliomi per la sanità pubblica, il sostegno alle politiche di welfare e la prevenzione dei rischi. Lo sviluppo di progetti per tendere a una maggiore uniformità nei metodi di ricerca dei casi, di classificazione delle diagnosi e dell'esposizione e nelle tecniche di analisi dei dati potrebbe consentire una maggiore fruibilità dei dati aggregati. La disponibilità di dati internazionali confrontabili può essere di stimolo all'adozione di provvedimenti di bando internazionale.

OBJECTIVE: To show how malignant mesothelioma (MM) surveillance not only identifies settings of exposure representing past industrial history, but it may also detect conditions of current exposure relevant for the prevention, if the wide spectrum of asbestos uses is considered. DESIGN: Active search of MM cases and exposure assessment at individual level through a questionnaire; identification of exposure circumstances relevant for prevention. SETTING AND PARTICIPANTS: Italy, all the Regions where a Regional Operating Centre (COR) is established to identify all MM cases diagnosed in the population and analyze their occupational, residential, household and environmental histories. Period of diagnosis: 1993-2008. MAIN OUTCOME MEASURES: Descriptive analysis of MM cases and of asbestos exposures. RESULTS: ReNaM includes 15,845 cases of MM diagnosed between 1993 and 2008.The male/female ratio is 2.5. Mean age at diagnosis is 69 years. Pleural MMs represent 93% of all cases. Exposures have been investigated in 12,065 cases (76%). The median latency time is 46 years. In addition to clusters of MM cases in activities well known to entail asbestos use, different current exposure circumstances requiring intervention have been evidenced. CONCLUSIONS: On the basis of this experience, epidemiological surveillance of all occupational cancers should be implemented to foster synergies with the compensation system and the Local Health Authorities' occupational safety and health services, as required by the Italian Legislative Decree N. 81/2008.

National epidemiologic surveillance systems of asbestos-related disease and the exposed workers register.

INTRODUCTION: Italy was the main European producer of asbestos for most of the 20th century and raw asbestos imports wee also significant until the 1990's; there was a mean delay of about ten years in the pattern of asbestos consumption in Italy compared with the USA, Australia, UK and Scandinavian countries. METHODS: A national surveillance system (ReNaM) was implemented to identify cases of mesothelioma and investigate the modalities of asbestos exposure. A register of exposed workers and a database of companies presumably involved in the asbestos exposure problem was also developed. ReNaM has a regional structure and an operative centres (COR) have been established in 16 Italian regions. RESULTS: The ReNaM database currently contains more than 5,000 mesothelioma cases and for 3,500 of these exposure modalities have been defined. Cases of pleural mesothelioma represent 93% of the total but there were also 334 cases of peritoneal mesothelioma, 15 of the pericardium and 14 of the tunica vaginalis of the testicle. Cases with ascertained exposure are thus distributed: 67.4% occupational exposure (ascertained, probable, possible), 4.3% domestic, 4.2% environmental and 1.3% hobby-related exposure, totalling 77.2%; 22.8% had unlikely or unknown exposure. The latency period is very long: on average 43.6 years. The register of asbestos-exposed workers contains figures on exposed workers notified to ISPESL up to 2004 and refers to the exposure period 1993-2003. The data registered cover 160 firms and about 700 workers. CONCLUSIONS: A national, coordinated and uniform epidemiological surveillance system of cases of mesothelioma and the definition of asbestos exposure through active research is extremely important in identifying unexpected contaminating sources. The register of asbestos-exposed workers allows risk to be monitored and protection measures to be implemented.
