The study involves the use of reagents or materials for diagnostic assessments that are not commercially available, specifically a metabolomic signature for screening endometrial carcinoma and/or other types of cancers, and follows a case-control design. This study aims to achieve several objectives that contribute to evaluating the diagnostic potential of a specific metabolomic signature to be used for screening endometrial carcinoma. Specifically, the study seeks to assess the signature's discriminative ability in differentiating between benign endometrial neoplasms and neoplasms of different histological origins.
