Hemoglobin A1c and the relationship to stage and grade of endometrial cancer
OBJECTIVES/OBJECTIVE:To determine if elevated markers of poor glycemic control (HgA1c and fasting glucose levels) in patients surgically staged for type I endometrial cancer is related to a higher stage or higher grade at the time of diagnosis. Also, to assess if these markers impact overall survival. METHODS:A retrospective chart review was performed from January 2000 to June 2010 at three academic medical centers. Patients were included if they underwent surgical staging and had HgA1c drawn within 3Â months before surgery. Demographic data, fasting blood glucose levels and overall survival data were also obtained. RESULTS:Eighty-two patients fitting the inclusion criteria were identified during the study period. There was a strong positive correlation between HgA1c and fasting glucose. There was no statistical difference with regard to stage alone, grade alone, or when stratified together with regard to HgA1c or fasting glucose levels. There was a trend toward increased mean HgA1c across increasing stages, but this was not statistically significant. Diabetes, HgA1c and tumor grade did not affect overall survival, but advanced stage was a poor prognostic measure for overall survival. CONCLUSIONS:Elevated preoperative HgA1c has a trend toward a higher stage at the time of diagnosis. Advanced stage is a poor prognostic measure for overall survival.
