Metabolic syndrome has been identified as a risk factor for colorectal cancer and adenoma. The aim of our study was to assess the risk of colorectal cancer and adenoma in an adult Italian population with metabolic syndrome. Ninety patients with metabolic syndrome were prospectively compared against a matched population without the syndrome to assess the prevalence of colorectal adenoma. Another 1,500 patients undergoing screening colonoscopy were prospectively analyzed: 134 patients with metabolic syndrome and colorectal adenoma were compared against a group of 108 patients with colorectal adenoma without metabolic syndrome to assess the prevalence of cancer. The study was performed from January 2008 until December 2010. Data were analyzed from March to June 2011. The prevalence of colorectal adenoma was twice as high in patients with metabolic syndrome. The incidence of cancer was higher in patients with colorectal adenoma and metabolic syndrome. Associated obesity and liver steatosis were the only factors with independent statistical value. Metabolic syndrome is a risk factor for adenoma and cancer degeneration when obesity is present. Associated liver steatosis is a significant risk factor for colorectal cancer.
