Aims. Exposure to asbestos represents an important risk factor for the onset of pleural and peritoneal mesothelioma. An association with gastrointestinal and bile duct adenocarcinoma may also be possible. Patients and methods. In 2007, 55 patients with bile duct neoplasm who were admitted to our centre were investigated extensively about their exposure to known risk factors for their pathology and about exposure to asbestos. For each patient their medical history, their past, recent and current pathology was collected in detail. Information on the workplace and characteristics of their working environment, job description, use and frequency of direct and indirect exposure to asbestos, sources of non-occupational exposure, residential and daily life background was collected. Exposure to asbestos is considered significant only in cases where the latency period is equal to or longer than ten years. Results. From the medical history of the 55 cases, it emerged that 18 had been exposed to asbestos. In 3 cases the patients had been exposed by inhalation in a workplace setting, while in the other 15 cases an exposure linked to a presumable ingestion of asbestos fibres contained in the water collected in domestic asbestos-cement water tanks was postulated. Conclusions. A weak association between tumours of the bile ducts and exposure to asbestos has already been postulated in the past on the basis of studies conducted on cohorts of workers exposed to asbestos. Our analysis also indicates a possible association between exposure to asbestos and neoplasms of the biliary ducts. Eur. J. Oncol., 13 (3), 171-179, 2008

Finalità. L’esposizione all’amianto rappresenta un importante fattore di rischio per l’insorgenza di mesoteliomi pleurici e peritoneali. È possibile che l’associazione possa esistere anche con i carcinomi del tratto gastrointestinale e delle vie biliari. Pazienti e metodi. Nel 2007, 55 pazienti affetti da neoplasie delle vie biliari afferiti al nostro centro sono stati indagati in maniera esaustiva circa l’esposizione a fattori di rischio conosciuti per la patologia e sull’esposizione all’amianto. Per ogni paziente è stata raccolta accuratamente l’anamnesi fisiologica, la patologica remota, recente e attuale. Sono state raccolte informazioni su sede e caratteristiche dell’ambiente lavorativo, tipologia delle mansioni svolte, utilizzo e frequenza dell’esposizione diretta o indiretta all’amianto, fonti di esposizione non occupazionali, storia residenziale e familiare. L’esposizione all’amianto è stata considerata significativa solo nei casi in cui il tempo di latenza sia stato uguale o superiore a dieci anni. Risultati. Dall’anamnesi è emersa un’esposizione all’amianto in 18 dei 55 casi. In 3 casi i pazienti erano stati esposti per via aerea per ragioni occupazionali, mentre negli altri 15 si trattava di una esposizione legata a presumibile ingestione di fibre di amianto contenute nell’acqua, raccolta in serbatoi domestici di cementoamianto. Conclusioni. Una debole associazione fra tumori delle vie biliari ed esposizione all’amianto è stata postulata già in passato sulla base di studi condotti su coorti di lavoratori esposti all’amianto. Anche nel nostro caso si può ipotizzare una associazione tra esposizione ad amianto e neoplasia delle vie biliari. Eur. J. Oncol., 13 (3), 171-179, 2008

Abstract

Aims. Exposure to asbestos represents an important risk factor for the onset of pleural and peritoneal mesothelioma. An association with gastrointestinal and bile duct adenocarcinoma may also be possible. Patients and methods.

For each patient their medical history, their past, recent and current pathology was collected in detail. Information on the workplace and characteristics of their working environment, job description, use and frequency of direct and indirect exposure to asbestos, sources of non-occupational exposure, residential and daily life background was collected.
