About leiomyosarcoma

Leiomyosarcomais a very rare, but very treatable cancer. It’s a type of soft tissue sarcoma (cancer) that grows in muscle tissue in muscles, including muscles in the skin and organs. In children, it usually grows in the gastrointestinal tract. Since it is in the soft tissue areas, it can be difficult to detect because they are covered by other structures such as skeletal muscle.

  • Leiomyosarcoma can spread (metastasize) to other areas of the body, but usually does not if it is removed early.
  • Its cause is unknown but has been linked to genetics and inherited diseases.
  • Children with AIDS are at risk for developing this kind of cancer.
  • A tumor may exist for a long time before being discovered.
  • Treatment usually involves surgery and potentially radiation and/or chemotherapy.
  • Leiomyosarcoma is very treatable, with 80% success rate if the tumor is completely removed.
  • There are no gender related risks among children. Girls and boys have equal risks of having leiomyosarcoma.
  • It is extremely rare. There are only 20 to 30 cases of child leiomyosarcoma cases per year in the United States.
  • The outlook is very good if the tumor is completely removed.
