: Informed consent was given by patients diagnosed with endometrial carcinoma between 2000 and 2018, for the use of their samples in research, at their first visit to our hospital. Information derived from our research, using the samples collected after informed consent was obtained, has been summarised on our hospital website. Patients were free to revoke their consent at any time point. In this study, only samples from patients who did not revoke their consent were used. We also informed patients treated before the year 2000 that the information summary of the study is published on the official hospital website. Patients who refused to provide consent for the use of their residual samples were excluded from this study.
