BACKGROUND/
AIMS:
Hyperglycemia is associated with decreased 2-18[F]fluoro-2-deoxy-D-glucose (FDG) uptake by tumors assessed by positron emission tomography (PET). In this retrospective study we investigated a comparison of standardized uptake values (SUVs) in patients with primary colorectal cancers who either had diabetes mellitus (DM) or were otherwise healthy.METHODS:
The medical records of 397 patients who were diagnosed with colorectal cancer and underwent PET-CT between January 2006 and December 2012 were analyzed. Eighty patients with DM and 317 patients without DM were included. Clinical characteristics were reviewed and maximal standardized uptake values (SUVmax) were calculated in the primary colorectal lesions.RESULTS:
There was no significant difference between tumor SUVmax in DM patients (10.60+/-5.78) and those without DM (10.92+/-5.44). In addition, no significant difference was detected between tumor SUVmax in DM patients with glycated hemoglobin (HbA1c) levels or =8% (10.61+/-7.27). The maximum size of the primary colorectal tumor was associated with SUVmax in a linear regression analysis.CONCLUSION:
The results of this study showed that DM did not influence FDG uptake values in colorectal cancer patients regardless of glucose levels.
