title: The value of red blood cell distribution width in endometrial cancer.
abstract: BACKGROUND
  Red cell distribution width (RDW) is a routinely examined parameter with the complete blood count. In recent studies, RDW levels have been associated with cardiovascular, liver and renal diseases and solid tumors. The aim of this study was to evaluate the alterations of RDW levels in benign and malignant causes of postmenopausal bleeding and to investigate the association of RDW levels with clinicopathological parameters of endometrial cancer (EC) patients.
  
  
  METHODS
  A retrospective study was made of a total of 884 females who were admitted to hospital for postmenopausal bleeding between May 2009 and December 2013. After inclusion and exclusion criteria were applied, 222 patients remained. Complete blood count data was obtained from the recorded computerized database. After pathological evaluation, the patients were divided into two groups, benign and malignant (EC).
  
  
  RESULTS
  The EC group (n=113) had significantly higher RDW levels compared to the benign group (14.78±2.02 vs. 13.88±1.05; p=0.000). Grade II and above EC patients had higher levels of RDW than Grade I patients (15.2±2.3 vs. 14.1±1.00; p=0.005). Correlation analyses also revealed a negative correlation between RDW and hemoglobin levels (p=0.000), RDW and mean corpuscular volume (p=0.000), RDW and lymphocyte count (p=0.035) but a positive correlation between RDW and platelet to lymphocyte ratio (p=0.030).
  
  
  CONCLUSIONS
  The results of the current study revealed the potential predicitve role of RDW in patients with postmenopausal bleeding. Significant associations were also determined between RDW and clinicopathological characteristics in EC patients.
