Microsatellite instability (MSI) is one of the four types of endometrial carcinoma (EC) molecular classification based on The Cancer Genome Atlas (TCGA) [1], which refers to the high mutation load caused by the failure of EC to correct certain errors in small sequence replication due to the abnormal function of DNA mismatch repair system [2]. The purpose of this study is to explore the value of multiple quantitative parameters of APT and DKI sequences in evaluating EC MSI status.
