How to diagnose leiomyosarcoma?
Tests and procedures used to diagnose leiomyosarcoma depend on where the cancer occurs, but may include: 1 Physical exam. Your doctor may examine you to gather more clues about what's causing any signs and symptoms you may be experiencing. 2 Imaging tests. Imaging tests might include MRI, CT and positron emission tomography (PET). 3 Removing a sample of tissue for testing (biopsy). A biopsy procedure involves removing a sample of suspicious tissue for testing. The sample is sent to a lab where it's analyzed to see if it's leiomyosarcoma.#N#How the biopsy sample is collected depends on where the suspicious tissue is located. The procedure requires careful planning so that the biopsy is done in a way that won't interfere with future surgery to remove the cancer. For this reason, ask your doctor for a referral to a team of experts with experience in treating leiomyosarcoma.

What is a leiomyosarcoma?
Specialty. Hematology and Oncology. Leiomyosarcoma is a malignant ( cancerous) smooth muscle tumor. A benign tumor originating from the same tissue is termed leiomyoma. While leiomyosarcomas are not thought to arise from leiomyomas, some leiomyoma variants' classification is evolving.

Where are smooth muscle cells found?
Smooth muscle cells make up the involuntary muscles, which are found in most parts of the body, including the uterus, stomach and intestines, the walls of all blood vessels, and the skin, so leiomyosarcomas can appear at any site in the body. They are most commonly found in the uterus, stomach, small intestine and retroperitoneum.

What is a leiomyosarcoma?
Leiomyosarcoma is a malignant (cancerous) tumor that arises from smooth muscle Cells There are essentially two types of muscles in the body – voluntary and involuntary. Smooth muscles are involuntary muscles – the brain has no conscious control over them. Smooth muscles react involuntarily in response to various stimuli. For example, smooth muscle that lines the walls of the digestive tract causes wave-like contractions (peristalsis) that aid in the digestion and transport of food. Smooth muscles in the salivary glands cause the glands to squirt saliva into the mouth in response to taking a bite of food. Smooth muscle in the skin causes goose bumps to form in response to cold.
What is the function of smooth muscles?
Smooth muscles react involuntarily in response to various stimuli. For example, smooth muscle that lines the walls of the digestive tract causes wave-like contractions (peristalsis) that aid in the digestion and transport of food.

A rare, aggressive form of cancer called uterine leiomyosarcoma, which affects roughly 2,500 women every year in the U.S., is often discovered entirely by accident. The malignant smooth muscle tumor arises in the uterus and is frequently detected during a routine gynecological surgery. Most patients show no symptoms before diagnosis, but if the cancer has spread to other parts of the body, the prognosis is extremely poor.
What is olaparib used for?
The trial aimed to test a novel therapy for uterine leiomyosarcoma called olaparib, a PARP inhibitor originally developed for individuals with BRCA1 or BRCA2 mutations. “Uterine leiomyosarcoma is a deadly disease.
How long does olaparib last?
Six patients (27%) had a durable response that lasted an average of 12 months. Side effects of the therapy, which mostly included low blood counts, were tolerable without any serious complications.
How does olaparib work?
Olaparib works by blocking a family of proteins known as PARP that help repair damaged DNA. Harmful mutations in the BRCA1 or BRCA2 genes lead to faulty DNA repair, and further inhibiting this process with olaparib can cause cancer cells that carry a BRCA mutation to die.
Overview
Notable cases
People who have had leiomyosarcoma include:
• Leicester City footballer Keith Weller, who made over 300 appearances for the Foxes, scored 47 goals. Also, he made four appearances for England, scoring one goal.
• Katie Price
• Canadian public-health physician Sheela Basrur (1956–2008) developed uterine leiomyosarcoma in 2006.
Mechanism
Smooth muscle cells make up the involuntary muscles, which are found in most parts of the body, including the uterus, stomach and intestines, the walls of all blood vessels, and the skin, so leiomyosarcomas can appear at any site in the body. They are most commonly found in the uterus, stomach, small intestine and retroperitoneum.
Uterine leiomyosarcomas come from the smooth muscle in the muscle layer of the uterus. Cuta…
Diagnosis
Diagnosis of LMS is made by performing a soft-tissue biopsy and examining its histopathology.
Treatment
Surgery, with as wide a margin of removal as possible, has generally been the most effective and preferred way to attack LMS. If surgical margins are narrow or not clear of tumor, however, or in some situations where tumor cells were left behind, chemotherapy or radiation has been shown to give a clear survival benefit. While LMS tends to be resistant to radiation and chemotherapy, each case is different and results can vary widely.
