To clarify the relationship between standardized uptake values（SUV） of integrated FDG PET/CT and histopathologic findings in patients with endometrial cancers.

 Thirty consecutive women (mean age, 54.9 years) with endometrial cancer who underwent radical hysterectomy and pelvic dissection were investigated for maximum SUV of FDG PET/CT in correlation with tumor size, tumor depth, histopathologic grade and associated histopathologic inflammation.

Maximum SUV of FDG PET/CT was positively correlated with tumor size (correlation coefficient, 0.87; P < .0001). The group of endometrial cancer associated with histopathologic active inflammation had significant higher maximum SUV than the group of endometrial cancer associated with histopathologic inactive inflammation. Neither tumor depth nor histopathologic grade correlated with maximum SUV.

Standardized uptake values for endometrial cancers correlated with tumor size and with the degree of histopathologic inflammation.

 The correlation between FDG uptake and tumor grade can not demonstrate for endometrial cancers.
