Strengths and Limitations
As for the limitation, the data was restricted to the First Affiliated Hospital of Xi’an Jiaotong University, which was a single-center study with a small sample size. The collection place and sample size will be expanded to obtain more information.
Many pathologic types exist in endometrial cancer, including endometrioid adenocarcinoma, papillary serous carcinoma, clear cell carcinoma, adenosquamous carcinoma, mucinous adenocarcinoma (44). We calculated all types of them as a whole but not subdivided pathological patterns. It is not clear whether a difference between two methods exists in different pathological types of endometrial cancer. The histological and cytological results in the study were not completely in a single form, some of which combined different types of endometria. The most serious type was analyzed as the final pathological diagnosis. However, with the exception of the most severe lesion of endometria, it was not clear whether other types simultaneously affected the result.
