A leiomyosarcoma (LMS) is a rare malignant (cancerous) smooth muscle tumor. The word is . The stomach, bladder, uterus, blood vessels, and intestines are examples of hollow organs made up of smooth muscles where LMS can be located; however, the uterus and abdomen are the most common sites.
Although leiomyosarcomas are rare, they belong to the more common types of soft-tissue sarcoma, representing 10–20% of new cases. This type of cancer is more frequently diagnosed in adults as compared to children. When considering LMS specifically in the context of the uterus, it affects approximately 6 individuals per 1 million people in the United States each year. LMSs are resistant cancers, meaning they are generally not very responsive to chemotherapy or radiation. The best outcomes occur when the tumor tissue can be removed surgically at an early stage, while it is small and has not yet spread from the original site (it remains in situ).
