Abstract

Objectives: To evaluate the influence of mucinous differentiation in endometrioid endometrial cancer regarding spread and prognosis.

Material and methods: Endometrioid endometrial cancer cases between 2015 and 2020 were collected retrospectively and divided into two groups according to the cytoplasmic mucin including. Prognostic factors and cancer spread related parameters were evaluated.

Results: A total of 219 patients were enrolled in this study. One hundred twenty-two (55.7%) were endometrioid and 97 (44.3%) were in the mucinous differentiated endometrioid catagory. Age was similar between the groups (59.3 vs 58.7, p = 0.62), however, grade 3 lesions were more frequent in endometrioid type endometrial cancer (8.7% vs 1.4%, p < 0.01). Poor prognostic factors including myometrial invasion, lymphovascular space invasion (LVSI), lymph node metastases, peritoneal cytology, endocervical involvement, and stage were not significantly different between groups (p = 0.23, p = 0.49, p = 0.40, p = 0.15, p = 0.17, p = 0.55). The median overall survival time of endometrioid and mucinous differentiated endometrioid type endometrial cancer patients was determined 88.5 and 96.8 months, respectively (p = 0.46).

Conclusions: Mucinous differentiation in the endometrioid type of endometrial cancer does not seem to affect the prognosis in endometrioid endometrial cancer patients.
