Sarcoma is a rare cancer that starts in connective tissues such as bone, cartilage, and muscle. It develops when the cells that make up these tissues (called mesenchymal cells) begin to grow out of control.

Where are sarcomas derived from?

Sarcomas are cancers that develop from bones or soft tissues, such as fat, muscles, nerves, and more. Because bone and soft tissues can be found nearly everywhere in the body, a sarcoma can start in any part of the body.

Where does soft tissue sarcoma start?

Soft tissue sarcoma is a broad term for cancers that start in soft tissues (muscle, tendons, fat, lymph and blood vessels, and nerves). These cancers can develop anywhere in the body but are found mostly in the arms, legs, chest, and abdomen.

What is the main cause of sarcoma?

DNA mutations in soft tissue sarcoma are common. But they're usually acquired during life rather than having been inherited before birth. Acquired mutations may result from exposure to radiation or cancer-causing chemicals. In most sarcomas, they occur for no apparent reason.

Where are most soft tissue sarcomas found?

Soft tissue sarcoma can occur anywhere in your body, but the most common types occur in the arms and legs, and in the abdomen. Surgical removal is the most common treatment, although radiation and chemotherapy also may be recommended — depending on the size, type, location and aggressiveness of the tumor.

What is the most common site of sarcoma?

The most common locations are the hip, knee, ankle, and shoulder. This tumor is more common in children and young adults, but it can occur in older people. Undifferentiated pleomorphic sarcoma (UPS) was once called malignant fibrous histiocytoma (MFH).

How long can you have sarcoma without knowing?

Synovial sarcoma symptoms develop over time. Tumors can grow undetected for as long as two years.

What virus causes sarcoma?

Kaposi's sarcoma is caused by a virus called the human herpesvirus 8 (HHV-8), also known as the Kaposi's sarcoma-associated herpesvirus (KSHV). This virus is thought to be spread during sex, through saliva, or from a mother to her baby during birth.

Does stress cause sarcoma?

No, being stressed doesn't directly increase the risk of cancer. The best quality studies have followed up many people for several years. They have found no evidence that those who are more stressed are more likely to get cancer.

Do most people survive sarcoma?

The overall 5-year survival rate for sarcoma is 65%. About 60% of sarcomas are found as a localized sarcoma. The 5-year survival rate for people with localized sarcoma is 81%. About 18% of sarcomas are found in a locally advanced stage.

Where does sarcoma spread to first?

The lungs are the most common site where sarcomas spread, although metastases have been reported in most organs, including the liver, lymph nodes and bones.

What can be mistaken for sarcoma?

Since sarcomas can be mistaken for a benign tumor, a hematoma, an abscess or simply a lump of fat, it may sometimes be diagnosed at a late stage.

How long does it take for sarcoma to metastasize?

Synovial sarcomas usually metastasize after >5 years: a multicenter retrospective analysis with minimum follow-up of 10 years for survivors.

What does the beginning of sarcoma look like?

Most sarcomas start as a lump in the arm or leg. A lump that keeps growing is the most common symptom. Sometimes the lump hurts. When sarcomas start in the belly, they can cause belly pain or changes in the way you eat or go to the bathroom.

What were your first sarcoma symptoms?

Signs and symptoms of sarcoma include: A lump that can be felt through the skin that may or may not be painful. Bone pain. A broken bone that happens unexpectedly, such as with a minor injury or no injury at all.

Where does sarcoma spread to first?

The lungs are the most common site where sarcomas spread, although metastases have been reported in most organs, including the liver, lymph nodes and bones.

How do you know if you have soft tissue sarcoma?

There are often no obvious symptoms in the early stages of soft tissue sarcomas, although you may notice a soft, painless lump under your skin or deeper, that can't easily be moved around and gets bigger over time. You should speak to your GP if you have a worrying lump or any other troublesome symptoms.

How to save a sarcoma?

Surgery is the most common form of the treatment for most sarcomas that have not spread to other parts of the body. Limb-sparing surgery , as opposed to amputation, can now be used to save the limbs of patients in at least 90% of extremity (arm or leg) sarcoma cases. Additional treatments, including chemotherapy, radiation therapy (also called "radiotherapy") and proton therapy, may be administered before surgery (called " neoadjuvant " chemotherapy or radiotherapy) or after surgery (called " adjuvant " chemotherapy or radiotherapy). The use of neoadjuvant or adjuvant chemotherapy and radiotherapy significantly improves the prognosis for many sarcoma patients. Treatment can be a long and arduous process, lasting about a year for many patients.

How is sarcoma graded?

Like some other cancers, sarcomas are assigned a grade (low, intermediate, or high) based on the appearance of the tumor cells under a microscope. In general, grade refers to how aggressive the cancer is and how likely it is to spread to other parts of the body ("metastasize"). Low-grade sarcomas have a better prognosis than higher-grade sarcomas, and are usually treated surgically, although sometimes radiation therapy or chemotherapy are used. Intermediate- and high-grade sarcomas are more frequently treated with a combination of surgery, chemotherapy, or radiation therapy. Since high-grade tumors are more likely to undergo metastasis (invasion and spread to locoregional and distant sites), they are treated more aggressively. The recognition that many sarcomas are sensitive to chemotherapy has dramatically improved the survival of patients. For example, in the era before chemotherapy, long-term survival for pediatric patients with localized osteosarcoma was only about 20%, but now has risen to 60–70%.

How many people die from bone sarcoma in 2019?

The American Cancer Society (ACS) estimates that 1,660 people in the US will die in 2019 from bone sarcomas, accounting for 0.3% of all cancer deaths. The median age at death is 61 years old, although death can occur in any age group. Thus, 12.3% of bone sarcoma deaths occur in people under 20 years old, 13.8% occur in people 20–34 years old, 5.5% occur in people 35–44 years old, 9.3% occur in people 45–54 years old, 13.5% occur in people 55–64 years old, 16.2% occur in people 65–74 years old, 16.4% occur in people 75–84 years old, and 13.1% occur in people 85 years or older.

What are the two major groups of sarcomas?

Sarcomas are typically divided into two major groups: bone sarcomas and soft-tissue sarcomas, each of which has multiple subtypes. In the United States, the American Joint Committee on Cancer (AJCC) publishes guidelines that classify the subtypes of sarcoma. These subtypes are as follows:

How do you know if you have a bone sarcoma?

Signs and symptoms. Symptoms of bone sarcomas typically include bone pain, especially at night, and swelling around the site of the tumor. Symptoms of soft-tissue sarcomas vary, but they often present as firm, painless lumps or nodules.

What is a sarcoma?

Specialty. Oncology. A sarcoma is a malignant tumor, a type of cancer that arises from transformed cells of mesenchymal ( connective tissue) origin. Connective tissue is a broad term that includes bone, cartilage, fat, vascular, or hematopoietic tissues, and sarcomas can arise in any of these types of tissues.

What is the Ewing sarcoma gene?

Most cases of Ewing sarcoma are associated with a chromosomal translocation in which part of chromosome 11 fuses with part of chromosome 22. This results in the EWS gene becoming fused to other genes, including the FLI1 gene in 90% of Ewing cases and ERG gene in 5-10% of cases.

What are the different types of sarcomas?

Types of Sarcoma. Sarcomas are categorized as soft tissue or bone sarcomas, depending on where they develop in the body. Soft Tissue Sarcomas. Soft tissue sarcomas originate in the soft tissues of the body and are most commonly found in the arms, legs, chest or abdomen. Soft tissue tumors can occur in children and adults.

How many cases of sarcoma are there in the US?

According to the National Cancer Institute, about 12,000 cases of soft tissue sarcomas and 3,000 cases of bone sarcomas are diagnosed in the U.S. each year.

What are the symptoms of bone sarcoma?

The most common symptoms of bone sarcomas include the following: Pain and/or swelling in an arm or leg, the trunk, the pelvis or the back; swelling may or may not feel warm to the touch. A limited range of motion in a joint.

How is sarcoma treated?

Sarcoma Treatment. 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. Your treatment plan and recovery will depend on a variety of factors, including the following: type of sarcoma.

How do you know if you have a sarcoma?

Sarcoma Symptoms. 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.

Why is radiotherapy used for tumors?

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 body), stereotactic radiosurgery offers a noninvasive alternative to surgery.

What are the risk factors for sarcoma?

The most common sarcoma risk factors include the following: History of radiation therapy. Patients who have received radiation therapy for previous cancers may have a higher risk of developing a sarcoma. Genetic disorders.

How much does osteosarcoma cancer survive?

More aggressive sarcomas are harder to treat successfully. The survival rate for osteosarcoma is between 60% and 75% if the cancer has not spread outside the area it started. It is more likely to be cured if all of the cancer can be removed by surgery. Pagination. 1.

What is the first treatment for cancer?

Chemo is often the first treatment when the cancer has spread. Targeted therapies are newer treatments that use drugs or manmade versions of antibodies from the immune system to block the growth of cancer cells while leaving normal cells undamaged. Surviving Sarcoma.

What tests are needed for sarcoma?

If your doctor thinks you may have a sarcoma, you'll probably need a full exam and tests, including: A sample of cells from the tumor, called a biopsy. Imaging tests, such as a CT scan, an ultrasound, or an MRI, to help see inside your body. A bone scan, if you might have osteosarcoma. Sarcoma Treatments.

What to do if your child has a sarcoma?

Diagnosing Sarcoma. If your doctor thinks you may have a sarcoma, you'll probably need a full exam and tests, including:

What are the risk factors for sarcoma?

Sarcoma Risk Factors. We don't yet know what causes sarcoma, but we do know some things that raise the risk of developing one: You have a genetic disorder such as neurofibromatosis, Gardner syndrome, retinoblastoma, or Li-Fraumeni syndrome.

How is sarcoma treated?

How your sarcoma is treated depends on what type you have, where in your body it is, how developed it is, and whether or not it has spread to other parts of your body, or metastasized. Surgery takes the tumor out of your body.

What is a soft tissue sarcoma?

Sarcomas are different from the much more common carcinomas because they happen in a different kind of tissue. Sarcomas grow in connective tissue -- cells that connect or support other kinds of tissue in your body.

What causes a sarcoma?

In some cases, sarcomas have been linked to past exposure to radiation, certain chemicals or viruses.

Are sarcomas hereditary?

Not that we know of. However, you may inherit genes that could make you more likely to get a sarcoma. For example, children with familial retinoblastoma syndrome have a gene mutation that makes them predisposed to osteosarcoma .

Where can sarcoma spread?

The larger the tumor, or the higher the grade, the more likely it is to metastasize. The lungs are the most common site where sarcomas spread, although metastases have been reported in most organs, including the liver, lymph nodes and bones.

Can a sarcoma come back?

Like most other cancers, a sarcoma may recur. When we perform sarcoma surgeries at Johns Hopkins, we aim for what we call a negative margin. This means cutting out the tumor and enough surrounding tissue to remove as many cancerous cells as possible. We may also use radiation treatment or chemotherapy to kill any remaining sarcoma cells.

What if a sarcoma spreads to my lungs?

If sarcoma spreads to the lungs, we try to determine if the tumors can be safely removed. If surgery is not an option, other treatments, such as biological therapy, chemotherapy and radiation therapy, may be recommended. Biological therapy uses living microorganisms to target cancer cells directly or stimulate your entire immune system. One example of biological therapy is the drug pazopanib, which was approved for treatment of soft tissue sarcomas. Radiation and chemotherapy are two other options for a sarcoma that has spread to the lungs. If these treatments are not successful, you may be eligible to participate in a clinical trial.

What happens after a sarcoma surgery?

Once the surgery is finished, you will go through a period of recovery. It may include rehabilitation, physical therapy, occupational therapy and other care to manage the side effects of your treatment.

Is there a link between diet and recurrence of sarcoma?

A healthy diet is good for you whether you have a sarcoma or not. But there is no known link between diet and sarcoma recurrence. Regardless, getting nutrients from healthy foods can help your body better manage side effects of sarcoma treatment.

What is the most common soft tissue sarcoma in children?

Infantile fibrosarcoma is the most common soft tissue sarcoma in children under one year of age. It tends to be slow-growing and is less likely to spread to other organs than adult fibrosarcomas.

Where does sarcoma start?

A sarcoma is a type of cancer that starts in tissues like bone or muscle. Bone and soft tissue sarcomas are the main types of sarcoma. Soft tissue sarcomas can develop in soft tissues like fat, muscle, nerves, fibrous tissues, blood vessels, or deep skin tissues. They can be found in any part of the body.

What is a stromal tumor?

What age do you get a soft part sarcoma?

It's most common in people between the ages of 20 and 60, but can occur in people of any age, even in infants. Alveolar soft-part sarcoma is a rare cancer that mostly affects young adults. These tumors most commonly start in legs.

What does it mean when a tumor is benign?

The word benign means they're not cancer. These tumors can't spread to other parts of the body. Some soft tissue tumors behave in ways between a cancer and a non-cancer. These are called intermediate soft tissue tumors. When the word sarcoma is part of the name of a disease, it means the tumor is malignant (cancer).

Why are spindle cell tumors called spindle cell tumors?

Spindle cell tumors. Spindle cell tumor and spindle cell sarcoma are descriptive names used because the cells look long and narrow under the microscope. Spindle cell tumor is not a specific diagnosis or a specific type of cancer.

How long does it take for a sarcoma to recur?

You may need abdominal, pelvic, or bone scans depending on which type of sarcoma you had. “While most sarcoma recurrences happen in the first two years after diagnosis, there are types of sarcoma that can recur many years later,” Dr. Crago adds.

What does it mean when a sarcoma recurrence is local?

Some sarcoma recurrences are local. This means the sarcoma has come back in the same location as the original tumor. Other sarcomas are distant (also called metastatic sarcoma). This means the disease has spread to another part of the body.

Where does metastatic sarcoma happen?

Aimee M. Crago soft tissue sarcoma surgeon. Metastatic sarcoma, on the other hand, happens most often in the lungs, and you will not be able to detect it on your own.

What is the third type of recurrence?

A third type of recurrence, called regional recurrence, is much less common and refers to sarcoma that has spread to nearby tissues such as the lymph nodes. Treatment recommendations vary based on the exact location of the recurrence as well as which sarcoma subtype you have.

How long does it take for a soft tissue sarcoma to come back?

Fear of the cancer coming back is common among people who’ve recently been treated for soft tissue sarcoma. Most recurrences tend to happen within two years of diagnosis. It may be exhausting to think about but preparing yourself with some important information may help you feel less overwhelmed.

Can sarcoma come back?

1. Soft tissue sarcoma can recu r in different areas of the body. One of the most important things to know about sarcoma recurrence is that it can come back in the same location or in a different area of the body, says soft tissue sarcoma surgeon Aimee Crago. Some sarcoma recurrences are local. This means the sar coma has come back in ...

Does MSK have immunotherapy?

MSK has among the largest number of clinic al trials for sarcoma in the world, including an extensive immunotherapy program specifically for soft tissue sarcoma . “Clinical trials are where the rubber meets the road, where cutting-edge science converges with patient care,” says Dr. Tap. “For a patient, clinical trials are really about options. And we have a lot of options we can offer people with advanced sarcoma.”

How is osteosarcoma treated?

Treatment usually involves chemotherapy, surgery and, sometimes, radiation therapy . Doctors select treatment options based on where the osteosarcoma starts, the size of the cancer, the type and grade of the osteosarcoma , and whether the cancer has spread beyond the bone.

What to do if your child has osteosarcoma?

Make an appointment with your child's doctor if your child has any persistent signs and symptoms that worry you. Osteosarcoma symptoms are similar to many more-common conditions, such as sports injuries, so your doctor may investigate those causes first. There is a problem with information submitted for this request.

Where does osteosarcoma start?

Osteosarcoma is a type of bone cancer that begins in the cells that form bones. Osteosarcoma is most often found in the long bones — more often the legs, but sometimes the arms — but it can start in any bone. In very rare instances, it occurs in soft tissue outside the bone. Osteosarcoma tends to occur in teenagers and young adults, ...

What is the purpose of DNA in a cell?

A cell's DNA contains the instructions that tell a cell what to do. The changes tell the cell to start making new bone when it isn't needed. The result is a mass (tumor) of poorly formed bone cells that can invade and destroy healthy body tissue. Cells can break away and spread (metastasize) throughout the body.

Can osteosarcoma be controlled with chemotherapy?

The aggressive chemotherapy needed to control osteosarcoma can cause substantial side effects, both in the short and long term. Your health care team can help you manage the side effects that happen during treatment and provide you with a list of side effects to watch for in the years after treatment.

Can osteosarcoma spread to other bones?

Osteosarcoma can spread from where it started to other areas, making treatment and recovery more difficult. Osteosarcoma that spreads most often spreads to the lungs and to other bones. Adapting to limb amputation. Surgery that removes the tumor and spares the limb is used whenever possible.

Can you use an artificial limb to remove cancer?

Surgery that removes the tumor and spares the limb is used whenever possible. But sometimes it's necessary to remove part of the affected limb in order to remove all of the cancer. Learning to use an artificial limb (prosthesis) will take time, practice and patience. Experts can help you adapt.

How does liposarcoma form?

Doctors know that liposarcoma forms when a fat cell develops errors (mutations) in its genetic code. The mutations tell the cell to multiply rapidly and to go on living when other cells would die. The accumulating abnormal cells form a mass (tumor). Several types of liposarcoma exist.

What are the symptoms of a liposarcoma?

Liposarcoma that forms in the arms and legs can cause: A growing lump of tissue under your skin. Pain. Swelling. Weakness of the affected limb. Liposarcoma that forms in the abdomen can cause: Abdominal pain. Abdominal swelling.

Where does liposarcoma occur?

Liposarcoma can occur in fat cells in any part of the body, but most cases occur in the muscles of the limbs or in the abdomen. Liposarcoma occurs most often in older adults, though it can occur at any age. Treatment for liposarcoma typically involves surgery to remove the cancer.

Does liposarcoma spread quickly?

Several types of liposarcoma exist. Some grow slowly and the cells stay in one area of the body. Other types grow very quickly and may spread to other areas of the body. By Mayo Clinic Staff. Liposarcoma care at Mayo Clinic.

Overview

A sarcoma is a malignant tumor, a type of cancer that arises from transformed cells of mesenchymal (connective tissue) origin. Connective tissue is a broad term that includes bone, cartilage, fat, vascular, or hematopoietic tissues, and sarcomas can arise in any of these types of tissues. As a result, there are many subtypes of sarcoma, which are classified based on the specific tissue and typ…

Classification

Sarcomas are typically divided into two major groups: bone sarcomas and soft-tissue sarcomas, each of which has multiple subtypes. In the United States, the American Joint Committee on Cancer (AJCC) publishes guidelines that classify the subtypes of sarcoma. These subtypes are as follows:
• Osteosarcoma

Signs and symptoms

Symptoms of bone sarcomas typically include bone pain, especially at night, and swelling around the site of the tumor.
Symptoms of soft-tissue sarcomas vary, but they often present as firm, painless lumps or nodules. Gastrointestinal stromal tumors (a subtype of soft tissue sarcoma) often are asymptomatic, but can be associated with vague complaints of abdominal pain, a feeling of fullness, or other signs …

Cause

The cause of most bone sarcomas is not known, but several factors are associated with an increased risk of developing bone sarcoma. Previous exposure to ionizing radiation (such as prior radiation therapy) is one such risk factor. Exposure to alkylating agents, such as those found in certain cancer chemotherapeutic medicines, also increases the risk of bone sarcoma. Certain inherited genetic syndromes, including Li-Fraumeni syndrome, heritable RB1 gene mutations, and Paget's …

Mechanisms

The mechanisms by which healthy cells transform into cancer cells are described in detail elsewhere (see Cancer main page; Carcinogenesis main page). The precise molecular changes that result in sarcoma are not always known, but certain types of sarcomas are associated with particular genetic mutations. Examples include:
• Most cases of Ewing sarcoma are associated with a chromosomal translocation in which part of c…

Diagnosis

Diagnosis of bone sarcomas begins with a thorough history and physical examination which may reveal characteristic signs and symptoms (see Signs and Symptoms above). Laboratory studies are not particularly useful in diagnosis, although some bone sarcomas (such as osteosarcoma) may be associated with elevated alkaline phosphatase levels, while others (such as Ewing Sarcoma) can be associated with elevated erythrocyte sedimentation rate. Importantly, however…

Screening

In the US, the US Preventive Services Task Force (USPSTF) publishes guidelines recommending preventive screening for certain types of common cancers and other diseases. As of March 2019, the USPSTF does not recommend screening for sarcoma, possibly because it is a very rare type of cancer (see Epidemiology below).
The American Cancer Society (ACS) also publishes guidelines recommending preventive scree…

Treatment

Surgery is the most common form of the treatment for most sarcomas that have not spread to other parts of the body. Limb-sparing surgery, as opposed to amputation, can now be used to save the limbs of patients in at least 90% of extremity (arm or leg) sarcoma cases. Additional treatments, including chemotherapy, radiation therapy (also called "radiotherapy") and proton therapy, may be administered before surgery (called "neoadjuvant" chemotherapy or radiother…
