title: Assessment of hepatic steatosis on contrast enhanced computed tomography in patients with colorectal cancer.
abstract: OBJECTIVE
  Non-alcoholic fatty liver disease is often seen in patients with colorectal cancer. Insulin resistance and metabolic syndrome are related to increased risk of colorectal cancer. The aim of this study was to quantitatively determine the relationship between non-alcoholic fatty liver disease and colorectal cancer with the examination of routine abdominopelvic computed tomography images taken for staging.
  
  
  METHODS
  A retrospective evaluation was made of the colonoscopy and histopathology reports of 1630 patients who presented for a scanning or diagnostic colonoscopy examination. Colorectal cancer was determined histopathologically in 129 cases. Colorectal cancer patients with distant metastasis or additional malignancies were excluded from the study. A total of 105 patients met the criteria and were included in the study. A control group was formed of 94 patients with no history of cancer. The liver density on abdominopelvic computed tomography and serum transaminase values were recorded for the patients and compared with those of the control group.
  
  
  RESULTS
  The groups were similar in respect of age, gender and aspartate aminotransferase levels. Although not statistically significant, the alanine aminotransferase levels of the patient group were high compared to the control group. The liver density on computed tomography was statistically significantly lower in the patient group than in the control group.
  
  
  CONCLUSIONS
  The liver density measurement on contrast abdominopelvic computed tomography of colorectal cancer patients was low, which is consistent with non-alcoholic fatty liver disease.
