摘      要：A traditional belief widespread across the biomedical community was that dietary habits and genetic predisposition were the basic factors causing colorectal *** more recent times,however,a growing evidence has shown that other determinants can be very important in increasing(or reducing) incidence of this *** hypothesis that environmental and occupational risk factors are associated with colorectal cancer is gaining ground,and high risks of colorectal cancer have been reported among workers in some industrial *** aim of this study was to investigate the epidemiologic relationship between colorectal cancer and occupational exposures to several industrial activities,by means of a scientific literature review and *** work pointed out increased risks of colorectal cancer for labourers occupied in industries with a wide use of chemical compounds,such as leather(RR = 1.70,95%CI:1.24-2.34),basic metals(RR = 1.32,95%CI:1.07-1.65),plastic and rubber manufacturing(RR = 1.30,95%CI:0.98-1.71 and RR = 1.27,95%CI:0.92-1.76,respectively),besides workers in the sector of repair and installation of machinery exposed to asbestos(RR = 1.40,95%CI:1.07-1.84).Based on our results,the estimated crude excess risk fraction attributable to occupational exposure ranged from about 11% to about 15%.However,homogeneous pattern of association between colorectal cancer and industrial branches did not emerge from this review.
