Background: Recently preoperative hematologic parameters have attracted attention for their capacity to predict
tumor characteristics and recurrence. Considering the established role of tumor-associated macrophages (TAM) in the
tumor microenvironment, we evaluated the role of the preoperative monocyte count as a surrogate for TAM. Methods:
We retrospectively reviewed 166 patients with histopathologically proven endometrial cancers from January 2011 to
March 2015 and assessed any association of preoperative monocyte count with tumor characteristics and recurrence.
Results: The majority of patients had tumors with the following characteristics: endometrioid histology (83.1%), low
grade (grade I-II, 71.7%) and stage I disease (68.1%). The mean ± SD monocyte, neutrophil and platelet counts were 8.23
x 109/L ± 3.56 x 109/L, 64.0 x 109/L ± 11.3 x 109/L and 261.6 x 109/L ± 74.6 x 109. Statistically significant associations
were noted with between preoperative monocyte count and tumor stage (p value=0.044), recurrence (p value<0.001) and
omentum involvement (p value< 0.001) but not with tumor grade (p value=0.897), depth of myometrium involvement
(p value=0.479), lymphovascular space invasion (p value=0.269) and lymph node involvement (p value=0.377).
Conclusion: An elevated preoperative monocyte count is related to more aggressive tumors and a higher recurrence
rate in patients with endometrial cancer.
