Although they represent a small proportion of uterine cancers, they disproportionately contribute to mortality. Their biologic behaviors are highly variable, ranging from a locally invasive process with minimal metastatic risk to highly aggressive tumors that are characterized by intra-abdominal or disseminated hematogenous spread. This reflects the complex origin of the malignant tissue components: endometrium, endometrial stroma, and smooth muscle, plus supportive elements of the uterine corpus.
