EnglishTo add evidence to the limited data available from southern Europe, we assessed the association between processed meat consumption and colorectal cancer risk. We analyzed data from three case-control studies conducted between 1985 and 2010 in various Italian areas, including a total of 3745 incident cases and 6804 hospital-based controls. We calculated odds ratios (ORs) and 95% confidence intervals (CIs) by unconditional multiple logistic regression models. The median consumption of processed meat was around 20 g/day both in cases and controls. The OR of colorectal cancer was 1.02 (95% CI 0.99-1.04) for an increase of 10 g/day of processed meat. The association was statistically significant for colon cancer (OR 1.03, 95% CI 1.00-1.06), particularly for proximal colon cancer (OR 1.09, 95% CI 1.04-1.14), while there was no relation with rectal cancer (OR 0.99, 95% CI 0.95-1.03). The OR of proximal colon cancer was 1.38 (95% CI 1.08-1.75) for the highest sex-specific tertile of consumption (>25 g/day for men, >21.5 for women) compared with the lowest (<15 g/day), whereas no significant ORs were found for other anatomical subsites. Our findings indicate that there is no association with colorectal cancer overall, in the presence, however, of a positive association with proximal colon cancer.

| Abstract: | To add evidence to the limited data available from southern Europe, we assessed the association between processed meat consumption and colorectal cancer risk. We analyzed data from three case-control studies conducted between 1985 and 2010 in various Italian areas, including a total of 3745 incident cases and 6804 hospital-based controls. We calculated odds ratios (ORs) and 95% confidence intervals (CIs) by unconditional multiple logistic regression models. The median consumption of processed meat was around 20 g/day both in cases and controls. The OR of colorectal cancer was 1.02 (95% CI 0.99-1.04) for an increase of 10 g/day of processed meat. The association was statistically significant for colon cancer (OR 1.03, 95% CI 1.00-1.06), particularly for proximal colon cancer (OR 1.09, 95% CI 1.04-1.14), while there was no relation with rectal cancer (OR 0.99, 95% CI 0.95-1.03). The OR of proximal colon cancer was 1.38 (95% CI 1.08-1.75) for the highest sex-specific tertile of consumption (>25 g/day for men, >21.5 for women) compared with the lowest (<15 g/day), whereas no significant ORs were found for other anatomical subsites. Our findings indicate that there is no association with colorectal cancer overall, in the presence, however, of a positive association with proximal colon cancer. | |
