Sarcoma in leg


Home » What is Sarcoma? Soft-tissue sarcomas are more common than bone sarcomas. The 50 different types of soft-tissue sarcomas differ in terms of their tissue of origin, clinical behavior, age of occurrence, aggressiveness, the way they spread, genetic alterations, and their sensitivity to certain therapies.

This extremely rare sarcoma typically arises in the thigh or buttock of patients in their 20s. Men are much more commonly affected than women. While it does not appear particularly aggressive under the microscope, it travels very early to other sites of the body, including lung, chest cavity, liver, and bone, and occasionally to the brain. This form of sarcoma is relatively resistant to standard chemotherapy. Despite its early spread, people with this diagnosis can live for years or more after diagnosis, in some cases.

This uncommon group of sarcomas appear to arise from the lining of blood vessels endothelial cells or their precursors. They include less aggressive epithelioid hemangioendothelioma or EHE and more aggressive forms angiosarcoma s. Some blood-vessel sarcomas can affect the lymphatic system which carries fluid from soft tissue to lymph nodes. The vessels of the lymphatic system are lined with cells very similar to those found in blood vessels and give rise to what is termed lymphangiosarcoma.

Kaposi sarcoma is a form of blood-vessel sarcoma that is caused by a virus, HHV-8 also called KSHVin patients with HIV disease, as well as a group of typically older persons who have intact immune systems. These tumors have a high risk of recurring where they start and can also travel to liver, bone, lung, and other sites.

Even rarer tumors can arise from the sensory organs that regulate blood flow to different parts of the body. These are termed glomus tumors and can be painful. Surgery is usually the best way to treat this rare form of sarcoma.

An unusual and relatively less aggressive form of sarcoma that shows features of both fibroblasts and cells that retain fat xanthomas. The primary treatment is surgical. Radiation is occasionally used to try and prevent tumor recurrence, and chemotherapy is largely ineffective for this diagnosis.

These tumors metastasize spread very, very rarely. Some sarcomas that arise in soft tissue mimic those that typically arise in cartilage or bone. Many of these sarcomas have some but not all features in common with their bone-tumor equivalents, and each has unique characteristics that must be considered in their treatment.Soft tissue sarcomas are a diverse group of cancers that arise from fat, muscle, tendon, cartilage, lymphoid tissues, vessels, and so forth.

There are more than 80 types of soft tissue sarcoma. Although most sarcomas are soft tissue sarcomas, slope unblocked unity can also affect bone. The diagnosis and treatment of soft tissue sarcomas are involved and multidisciplinary, requiring the input of oncologistssurgical oncologists, radiologists, interventional radiologists, and more.

Treatment includes surgery, radiotherapy, and, in some cases, chemotherapy. The American Cancer Society estimated that 13, new cases of soft tissue sarcoma would be diagnosed in 7, cases in men and 5, cases in women.

Angiosarcomas and Other Sarcomas of Blood Vessels

The exact cause of most soft tissue sarcomas is unknown, and these lesions typically occur for no apparent reason. There are several genetic cancer syndromes that predispose someone to different types of soft tissue sarcomas. However, in some cases of soft tissue sarcoma, DNA mutations acquired after birth and secondary to radiation or carcinogen exposure may play a role in pathogenesis.

The most common soft tissue sarcomas in adults are undifferentiated pleomorphic sarcoma previously called malignant fibrous histiocytomaliposarcoma, and leiomyosarcoma. Liposarcomas and undifferentiated pleomorphic sarcomas most often present in the legs, and leiomyosarcomas are the most common abdominal sarcomas.

In children, the most common type of soft tissue sarcoma is rhabdomyosarcomawhich affects skeletal muscle. Among those people who die of soft tissue sarcoma, metastasis—or spread—to the lungs is the most common cause of death. It can resemble a lipomaor a benign tumor made of fat.

In fact, lipomas are times more common than soft tissue sarcomas and should be considered part of the differential diagnosis. In other words, a skin lump located on your arm or leg is much more likely to be a benign lipoma than a soft tissue sarcoma. About two-thirds of soft tissue sarcomas arise on the arms and legs.

The other one-third arise in the head, abdomen, trunk, neck, and retroperitoneum. The retroperitoneum is a space located behind the abdominal wall that contains the kidneys and pancreas as well as part of the aorta and inferior vena cava. Because soft tissue sarcomas often cause no symptoms, they are usually noticed only incidentally after a traumatic event that requires medical attention brings a person to the hospital. Soft tissue sarcomas of the distal extremities the parts of the arm and leg farthest from the torso are often smaller when diagnosed.

Soft tissue sarcomas that occur in either the retroperitoneum or proximal portions of the extremities those closest to the torso can grow quite large before being noticed. If a soft tissue sarcoma becomes big enough, it can impinge on surrounding structures such as bone, nerves, and blood vessels, and cause symptoms including pain, swelling, and edema.

Depending on location, larger sarcomas can obstruct the gastrointestinal tract and cause gastrointestinal symptoms such as cramps, constipation, and loss of appetite. Larger sarcomas can also impinge on the lumbar and pelvic nerves, thus resulting in neurological problems.

Finally, sarcomas located in the extremities can present like deep venous thrombosis. Small soft tissue masses that are new, non-enlarging, superficial, and fewer than 5 centimeters in size can be observed by a clinician with no immediate treatment. Enlarging masses that are deeper or bigger than 5 centimeters require a full workup entailing history, imaging, and biopsy.

Before the biopsy, diagnostic testing is used to evaluate soft tissue sarcoma. Magnetic resonance imaging MRI is most useful when visualizing soft tissue sarcomas located in the extremities. With respect to tumors that are retroperitoneal, intra-abdominal within the abdomenor truncal, computed tomography CT is most useful.

Other diagnostic modalities that can play a role in diagnosis are positron emission tomography PET and ultrasound. Radiography X-rays is not useful when diagnosing soft tissue tumors. After diagnostic testing, a biopsy is performed to examine the microscopic anatomy of the tumor. Historically, open incisional biopsies, which are surgeries that require general anesthesia, have been the gold standard when obtaining adequate tissue samples for histological diagnosis.

However, core needle biopsy, which is safer, less invasive, and more accurate and cost-effective, has become the preferred type of biopsy. Fine-needle aspiration is another biopsy option, but it is generally discouraged because it may be difficult to make an accurate primary diagnosis based on a small sample size.

Finally, when a lesion is smaller and closer to the surface, an excisional biopsy can be done. Although biopsy of more superficial tumors can be performed in an outpatient or office setting, deeper tumors need to be biopsied in the hospital by an interventional radiologist using ultrasound or CT for guidance.

Microscopic evaluation of soft tissue sarcomas is complicated, and even expert sarcoma pathologists disagree on histologic diagnosis and tumor grade at times.A sarcoma is a rare type of cancer that is different from the more common cancerous tumor, known as a carcinoma.

About Soft Tissue Sarcoma

Sarcomas can be found in connective tissue, which are cells that connect other kinds of tissues in the body. They are often found in the bones, muscles, tendons, cartilage, nerves, fat and blood vessels of arms and legs. But, they can be found anywhere in the body. Although there are more than 50 types of sarcoma, they can be grouped into two main kinds: soft tissue sarcoma and bone sarcoma, or osteosarcoma. According to the American Cancer Societyabout 12, new soft tissue sarcomas and 3, new bone sarcomas will be diagnosed in While the causes of sarcoma are unknown, scientists believe that the following factors increase the risk of developing the disease:.

The first sign of the disease often is a painless lump. When the lump grows in size, it can press against nerves or muscles and create discomfort. It can also make it hard for the patient to breathe. There are no tests that can find these tumors, before they cause noticeable symptoms. Osteosarcoma happens more frequently in children and young adults.

Sometimes, osteosarcoma can be mistaken for growing pains or a sports injury. The treatments for sarcoma vary depending on the type, the location in the body, how developed it is and whether or not it has spread to other parts of the body metastasized. In most cases of osteosarcoma, the cancer cells can be removed by surgerywithout removing a leg or an arm. Radiation also can shrink the tumor before surgery or kill the cancer cells that remain after a surgery. When the cancer has spread, chemotherapy is recommended.

Chemotherapy drugs can be used with or in place of surgery. Newer treatments include targeted therapies that use drugs or man-made versions of antibodies from the immune system to stop the growth of the cancer cells without harming normal cells.

More aggressive sarcomas are harder to fight successfully. Osteosarcoma has a better chance of being cured, if all of the cancer can be removed by surgery. Treatments for cancer are more effective the earlier the cancer is detected.

Facebook Twitter Linkedin Email.Ewing sarcoma is a cancerous tumor that can happen in any bone in the body, but most often happens in bones of the arms, legs, rib, spine and pelvis.

Occasionally, a tumor can develop outside of a bone in the soft tissue around it. Most cases happen in teens and young adults 10 to 20 years old and Ewing sarcoma affects more males than females. If the cancer spreads, or metastasizesit usually goes to the lungs, other bones, or to the bone marrow the spongy material inside the bone.

To diagnose Ewing sarcoma, a doctor will do an exam, take a detailed medical historyand order some tests. If the doctor diagnoses Ewing sarcoma, the child will have other imaging tests to see if the cancer has spread to any other part of the body. Doctors will also order blood tests to make sure that organs like the heart, liver, and kidneys are working well enough to tolerate treatment. Chemotherapy: Chemotherapy often is given first to shrink the tumor, improve pain, and stop the spread of cancer.

Doctors also may use chemotherapy after radiation therapy or surgery to prevent the cancer cells from coming back. Chemotherapy usually lasts 6 months to a year. During treatment, the child will usually stay in the hospital for a 3—6 days every 2 to 3 weeks.

Some kids may need to return to the hospital between treatments if they have side effectslike fever or infection, or if they need a blood transfusion. After chemotherapy, the doctor's goal is to continue to kill tumor cells around the tumor.

This can be done with:. Radiation therapy : High-energy X-rays are directed at the tumor to kill cancer cells. Doctors may use radiation to shrink the tumor before surgery. They may also use it instead of surgery if the tumor's location makes surgery difficult and might lead to long-term problems.

Surgery: The surgeon removes the tumor by cutting it out and trying to remove all of the tissue around the tumor that contains cancer cells. The goal is to have "negative margins" this means cancer cells are not seen under the microscope in the tissue from the area outside the tumor. Doctors sometimes do reconstructive surgery to rebuild the area where the tumor and other tissue was.

They can do this with:. Sometimes, to make sure they remove all the cancer, doctors might need to amputate the affected limb surgically removing all or part of it along with the tumor.

The types of symptoms that people have from a sarcoma depend on where it starts. People with sarcoma may experience the following symptoms or signs. Sometimes, people with sarcoma do not have any of these changes.

Or, the cause of a symptom may be a different medical condition that is not cancer. STS rarely causes symptoms in the early stages. The first sign of a sarcoma in an arm, leg, or torso may be a painless lump or swelling. Most lumps are not sarcoma. The most common soft-tissue lumps are lipomas. Lipomas are made of fat cells and are not cancer. Lipomas have often been there for many years and rarely change in size.

In the uterus, benign tumors called fibroids leiomyomas far outnumber sarcomas, but sarcomas of the uterus are sometimes mistaken for benign fibroids. People with a sarcoma that starts in the abdomen may not have any symptoms, or they may have pain or a sense of fullness. Because sarcoma can develop in flexible, elastic tissues or deep spaces in the body, the tumor can often push normal tissue out of its way as it grows. Therefore, a sarcoma may grow quite large before it causes symptoms.

Eventually, it may cause pain as the growing tumor begins to press against nerves and muscles. Sarcomas that start in other parts of the body may cause other symptoms or signs. For example, sarcomas in the uterus can cause uterine bleeding or an increase in the size of the uterus.

Bone and soft tissue sarcoma - recognition and referral

Tumors that start in the heart or a lung may cause breathing problems or pain in the chest. If you are concerned about any changes you experience, please talk with your doctor. This is to help figure out the cause of the problem, called a diagnosis. If a sarcoma is diagnosed, relieving symptoms remains an important part of cancer care and treatment. This may be called palliative care or supportive care.

It is often started soon after diagnosis and continued throughout treatment. Be sure to talk with your health care team about the symptoms you experience, including any new symptoms or a change in symptoms.

Soft tissue tumors can occur in children and adults. Bone sarcomas are primary bone tumors, which means that they develop in the bones. They are most commonly diagnosed in children. In addition to osteosarcomathe most common form of primary bone cancer, there are several other types of bone tumors.

The most common sarcoma risk factors include the following:. Early signs of soft tissue sarcoma can include a painless lump or swelling. Some sarcomas may not cause any symptoms until they grow and press on neighboring nerves, organs or muscles. Their growth may cause pain, a feeling of fullness or breathing problems. These symptoms could be signs of many other medical conditions. Always check with your doctor for a proper diagnosis. Sarcoma is treated with a combination of chemotherapy, radiation therapy and surgery.

Reconstruction of the surgical area typically takes place at the same time the tumor is removed. For primary tumors, radiation is used in conjunction with surgery either before or after to reduce the risk of tumor recurrence.

For patients with metastatic disease cancer that has spread to other areas of the bodystereotactic radiosurgery offers a noninvasive alternative to surgery. Patients with isolated metastasis might be treated with radiation in conjunction with chemotherapy as well as stereotactic radiosurgery.

Radiation is an essential part of treating most high-grade tumors. Health Home Conditions and Diseases.

Soft tissue cancers

If a diagnosis of soft tissue sarcoma is confirmed, these and further tests will also help determine how likely the cancer is to spread known as the "grade"and whether or how far the cancer has spread known as the "stage".

People with a soft tissue sarcoma are cared for by a team of doctors and nurses at specialist centres who will help to plan the most appropriate treatment. The best treatment depends on things such as where the cancer developed, the type of sarcoma it is, how far it has spread, your age and your general health.

It usually involves removing the tumour along with a section of surrounding healthy tissue. This helps to ensure no cancer cells are left behind. Every effort will be made to reduce the impact of surgery on the appearance and function of the affected body part. But there is a chance you'll have some difficulty using the affected body part after surgery and sometimes further surgery may be needed to repair it. In a very small number of cases, there may be no option but to amputate the part of the body where the cancer is located, such as part of the leg.

In some sarcomas, radiotherapy is used before or after surgery to improve the chance of cure. This is done using a machine that directs beams of radiation at a small treatment area.

Radiotherapy alone may also sometimes be used when surgery is not possible, to reduce symptoms caused by the sarcoma or slow its progression. Common side effects of radiotherapy include sore skin, tiredness and hair loss in the treatment area.

Soft tissue sarcoma can occur anywhere in your body, but the most common types occur in the arms and legs, and in the abdomen.
