:: Leiomyosarcoma (LMS) Defined ::

Leiomyosarcoma (Gr. Leio- =smooth, myo- = muscle, sarcoma = fleshy growth) is a type of sarcoma which is a neoplasm of smooth muscle. (When a uterine neoplasm is benign, it is a leiomyoma.) Smooth muscle cells make up the involuntary muscles, which are found in most parts of the body: in uterus, stomach and intestines, walls of all blood vessels, and skin. It is therefore possible for leiomyosarcomas to appear at any site in the body. It is however most commonly found in the stomach, small intestine and retroperitoneum.

Leiomyosarcoma is a very rare cancer. It makes up 5-10% of soft tissue sarcomas, which are in themselves rare cancers.

:: About Leiomyosarcoma ::

Leiomyosarcoma is a form of cancer that affects the smooth muscle of the body. It spreads through the blood stream and can affect the lungs, liver, blood vessels, or any other soft tissue in the body.

LMS is a type of sarcoma which is a neoplasm of smooth muscle. Smooth muscle cells make up the involuntary muscles, which are found in most parts of the body: in the uterus, stomach and intestines, walls of all blood vessels, and skin.

Leiomyosarcoma is a very rare cancer. It makes up 7% of soft tissue sarcomas; in all, LMS affects 4 out of 1,000,000 people.

Presently there is no cure. Remission can be attained, but this rare cancer can reappear at any time. Because of its rarity, few doctors know how to treat it and it attracts very little research.

Study findings on leiomyosarcoma are outlined in reports from University of Vienna, Medical Department



2009 JAN 5
-- "Uterine leiomyosarcoma during pregnancy is an extremely rare event. The incidence of meningioma during pregnancy is comparable with that in nonpregnant women of the same age group," investigators in Vienna, Austria report.

"We report a case of both - a primary uterine leiomyosarcoma and additionally all atypical meningioma of the brain both diagnosed during pregnancy. The patient was admitted with generalised seizures at 31 weeks of gestation. A tumoural mass was detected and initial conservative treatment was started. The patient delivered her infant via caesarean section, at 34 weeks of gestation. During caesarean section a pedunculated uterine fibroid was removed and total gross resection due to the brain tumour was also performed. Histopathological diagnosis of both tumours revealed an atypical meningioma of the brain and a uterine leiomyosarcoma. The patient underwent laparatomy and received six cycles of adjuvant chemotherapy. We are the first to report a case of a woman with two separate primary neoplasms both diagnosed during pregnancy," wrote B. Bodneradler and colleagues, University of Vienna, Medical Department.

The researchers concluded: "Treatment options seem to be reduced in pregnant women and mainly depend on the patient's condition as well as the gestational age at presentation."

Bodneradler and colleagues published their study in Anticancer Research (Primary Uterine Leiomyosarcoma and Primary Atypical Meningioma Diagnosed during Pregnancy. Anticancer Research, 2008;28(5B):3083-3085).
