Aims: To describe the cases of MM that occurred in the Friuli Venezia Giulia Region in the period 1995-2009 and evaluate the diagnostic contribution of autopsy findings. Methods: Via the Regional Register a search for MM cases was made following standardized criteria for diagnosis and past asbestos exposure assessment. Pleural plaques were identified by autopsy findings; the relationship between presence of pleural plaques and assessment of past asbestos exposure was analyzed. Results: 834 cases of MM were recorded and 458 autopsy findings were available; for 142 cases (15% of males and 23% of women) the first diagnosis was made at autopsy. Data were available on previous asbestos exposure in 91% (416 subjects) of cases with autopsy findings: 255 had “certain occupational exposure” (group 1), 116 “other occupational and non- occupational exposure” (group 2), 45 “negative and unknown exposure” (group 3). Logistic regression showed that significant predictors for pleural plaques were age at diagnosis (OR=1.03 each year (95% CI=1.01-1.05), asbestos exposure in group 1 versus group 2 (OR=6.8 (95% CI=4-12), and exposure in group1 versus group 3 (OR=6.4 (95% CI=3-13). Among subjects in groups 1 and 2, the presence of pleural plaques was significantly associated with latency (OR=1.03 for each year of latency; 95% CI=1.01-1.22) and asbestos exposure in group 1 versus group 2 (OR=7.8; 95% CI=4.4-13.0). Conclusions: Autopsy findings improved the diagnostic level of MM in elderly subjects, for whom reliable data on past asbestos exposure is often lacking. In subjects suffering from MM direct interview is always the best tool to evaluate past asbestos exposure; autopsy findings of pleural plaques cannot replace the anamnestic history when this is lacking, although such findings can act as a support

Abstract

Aims: To describe the cases of MM that occurred in the Friuli Venezia Giulia Region in the period 1995-2009 and evaluate the diagnostic contribution of autopsy findings. Methods: Via the Regional Register a search for MM cases was made following standardized criteria for diagnosis and past asbestos exposure assessment. Pleural plaques were identified by autopsy findings; the relationship between presence of pleural plaques and assessment of past asbestos exposure was analyzed. Results: 834 cases of MM were recorded and 458 autopsy findings were available; for 142 cases (15% of males and 23% of women) the first diagnosis was made at autopsy. Data were available on previous asbestos exposure in 91% (416 subjects) of cases with autopsy findings: 255 had “certain occupational exposure” (group 1), 116 “other occupational and non- occupational exposure” (group 2), 45 “negative and unknown exposure” (group 3). Logistic regression showed that significant predictors for pleural plaques were age at diagnosis (OR=1.03 each year (95% CI=1.01-1.05), asbestos exposure in group 1 versus group 2 (OR=6.8 (95% CI=4-12), and exposure in group1 versus group 3 (OR=6.4 (95% CI=3-13).
