Occupational and environmental cancer in southern Sardinia: a survey on ten years of hospitalizations = Tumori ad elevata frazione eziologica occupazionale o ambientale nella ASL di Cagliari: Un'analisi di 10 anni di ricoveri

Based on hospital discharges in 1001-2010, we calculated risk of tumours with an elevated occupational and environmental etiological fraction by health district of residence within the Local Health Unit (LHU) N. 8 of Sardinia. With reference to the age and gender-specific hospitalization rates of the whole LHU, residents in the urban Cagliari health district showed an excess risk of haemolymphopoietic cancer (RR = 1.07; 95%CI 1.03-1.12) and bladder cancer (RR = 1.10; 95%CI 1.05-1.16); in both instances, risks were higher among female residents. The highest excess risk for lung cancer was observed among residents in the Quartu-Parteolla health district (RR = 1.13; 95%CI 1.05-1.21), and it was slightly higher among male residents. The results appear to confirm the role of urban factors in increasing cancer risk.
