Introduction/Background We aimed to evaluate the consistency of the preoperative, intraoperative and postoperative pathology of endometrial cancer.

Methodology This was a retrospective study on 134 women (mean age 59.2±11.7 years) operated for endometrial cancer.

Results Preoperative pathologic diagnosis was endometrioid carcinoma in 85.1% of patients. Frozen section evaluation revealed endometrioid adenocarcinoma in 75.7%, and final pathology in 83.6% of patients. Myometrial invasion was 50% or over in 23.5% in frozen section and 27.1% in final pathology. The corpus-cervix border was involved in 25.9% intraoperatively and 18.9% postoperatively. The rate of consistency between preoperative and final assessment was 76.1% for histology. The rate of consistency between frozen section and final pathology was 68.5% for histology, 61.9% for myometrial invasion and 93% for the involvement of corpus-cervix border.

Conclusion Frozen section pathology results are not consistent with final pathology; thus unreliable in predicting the surgical stage of endometrial cancer.
