Sarcoma

Treatment

Sarcoma is often hard to treat, so it’s important to receive care at a specialized center with sarcoma expertise. Seattle Cancer Care Alliance (SCCA) experts offer comprehensive, team-based soft tissue sarcoma treatment as well as bone cancer treatment, including advanced therapies and new options available only through clinical studies.

In most cases, you have time to consider your options and get a second opinion — even a third opinion — before deciding what kind of treatment is right for you. A diagnosis of cancer can feel overwhelming. We have an experienced, compassionate team ready to help.

Clinical trial A type of research study that tests how well new medical approaches work in people. These studies test new methods of screening, prevention, diagnosis or treatment of a disease.

Sarcoma treatment tailored to you

We view treatment as a collaborative effort. Your SCCA doctors will explain all your options and recommend a treatment plan based on the size, location, grade and subtype of your tumor; whether it has spread; and the possible impact of treatment on your body and general health.

Grade In cancer, a grade is a description of a tumor based on how abnormal the cancer cells and tissue look under a microscope and how quickly the cancer cells are likely to grow and spread. In cancer, a grade is a description of a tumor based on how abnormal the cancer cells and tissue look under a microscope and how quickly the cancer cells are likely to grow and spread. Low-grade cancer cells look more like normal cells and tend to grow and spread more slowly than high-grade cancer cells. Grading systems are different for each type of cancer. They are used to help plan treatment and determine prognosis. Also called histologic grade and tumor grade. Treatment plan A detailed plan with information about a patient’s disease, the goal of treatment, the treatment options for the disease and the possible side effects and expected length of treatment. A detailed plan with information about a patient’s disease, the goal of treatment, the treatment options for the disease and the possible side effects and expected length of treatment. A treatment plan may also include information about how much the treatment is likely to cost and about regular follow-up care after treatment ends.

A team of experts all in one place

We bring everyone to you — your surgeon, medical oncologist and radiation oncologist — on the same day whenever possible. Your personal team will talk with each other and with you to help you make treatment decisions. Additional experts who specialize in treating people with cancer will be involved in your care if you need them — experts like a palliative care professional, social worker, physical therapist or dietitian.

Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS-HIPEC)

This treatment is for people with sarcoma that has spread to the abdominal lining (peritoneum). Cancer that has spread here is called peritoneal carcinomatosis, or peritoneal cancer.

CRS-HIPEC may be able to control advanced disease while also giving you good quality of life. It combines two parts in one operation:

A surgery to remove all the cancer that surgeons can see
Chemotherapy, in liquid form, that is warmed and then put into your abdomen to kill any cancer cells left behind after surgery

SCCA has an experienced team that provides CRS-HIPEC.

Chemotherapy

Chemotherapy is a major and important component of sarcoma care. It may be given before or after sarcoma surgery to reduce the risk of the cancer coming back or to allow complete surgical removal when this would otherwise be difficult. Chemo may also be used to reduce the size of tumors or to relieve pain and other symptoms.

Many chemotherapy medicines are given through an intravenous (IV) line in repeating cycles. There are also chemotherapy treatments for sarcoma given in tablet form.

Your SCCA team will talk with you about the specific medicines we recommend for you, how you’ll receive them, your treatment schedule and what to expect. We’ll also explain how to take the best possible care of yourself during treatment and after, and we’ll connect you with medical and support resources throughout SCCA.

Proton therapy

Proton therapy is an especially important treatment option if:

The tumor is located close to critical organs
The patient is trying to preserve particular functions, such as fertility
A patient has had prior radiation
The disease is recurrent

Recurring sarcomas may appear in different locations around the body over time. Protons can spare healthy tissue surrounding the tumor and minimize the area exposed to radiation. This is especially important if treatment is required several times over a life expectancy of many years.

The images above show a comparison plan between proton therapy (top) and conventional radiation (bottom) for leiyomyosarcoma of the left buttock. In this scenario, the reproductive organs are spared from harmful radiation.

Sarcomas that may be appropriate for proton therapy:

Chordoma
Leiomyosarcoma
Liposarcoma
- Myxoid liposarcoma
- Well-differentiated liposarcoma
- Dedifferentiated liposarcoma
- Pleomorphic liposarcoma
Undifferentiated pleomorphic sarcoma
Myxofibrosarcoma
Fibrosarcoma
Clear cell sarcoma
Angiosarcoma
Chondrosarcoma
Ewing’s sarcoma
Malignant peripheral nerve sheath tumor
Rhabdomyosarcoma
Synovial sarcoma
Gastrointestinal stromal tumor
Many childhood sarcomas

Gastrointestinal Refers to the stomach and intestines. Also called GI.

Proton therapy

Proton therapy limits radiation exposure to healthy tissue and helps preserve additional treatment options for recurrences.

Radiation therapy

You may have radiation therapy before or after surgery to reduce the risk of your sarcoma coming back. If your tumor cannot be removed surgically, doctors may use radiation therapy to control it. Radiation may also be used to reduce the size of the tumor or to relieve pain and other symptoms.

We've opened several studies looking at combinations of radiation therapy and immunotherapy — using radiation to make immunotherapy more effective, increasing the body's immune response against cancer.

Conventional external-beam radiation therapy (EBRT)

Conventional EBRT uses a machine called a linear accelerator to send beams of high-energy X-rays (photons) toward the cancer. Typically, EBRT is given five days a week (Monday through Friday) for several weeks. The procedure is painless, and each treatment lasts only a few minutes.

There are several forms of EBRT. Your radiation oncologist will determine the form that’s most appropriate for your tumors, set the dosage and schedule for your treatments and help you manage any side effects. Learn more about EBRT.

Intraoperative radiation therapy (IORT)

IORT is a fast, effective and precise form of radiation used during surgery to treat tumors. It may be used to treat tumors that came into contact with the tumor during surgery.

IORT takes just a few minutes to deliver and uses only a fraction of the total radiation given over a traditional multi-week course of EBRT. UWMC is the only hospital in the WWAMI region (Washington, Wyoming, Alaska, Montana and Idaho) to offer this treatment. Learn more about IORT.

Proton therapy

Proton therapy delivers radiation with great precision, significantly limiting radiation exposure to surrounding healthy tissues. This may reduce side effects from treatment and make proton therapy a better choice for certain sarcomas that are anatomically complex, such as those in the skull or spine. Learn more about proton therapy.

Fast neutron therapy

Neutron therapy bombards cancer cells with neutrons. There are two advantages to using neutrons instead of photons or electrons.

Neutron beams are much more powerful. They deposit about 20 to 100 times as much energy into the target tissue.
Neutron beams are more likely to damage both strands of a cancer cell’s DNA, rather than only one strand, making it harder for the cells to repair themselves and survive.

UWMC is the only place in the United States to offer neutron therapy, and doctors here are internationally recognized for their neutron therapy expertise. We sometimes use neutron therapy to treat sarcomas when we believe this may be more effective than conventional forms of radiation therapy. Read more about fast neutron therapy on the UW Medicine website.

Immunotherapy A type of therapy that uses substances to stimulate or suppress the immune system to help the body fight cancer, infection and other diseases. A therapy that uses substances to stimulate or suppress the immune system to help the body fight cancer, infection and other diseases. Some immunotherapies only target certain cells of the immune system. Others affect the immune system in a general way. Types of immunotherapy include cytokines, vaccines, bacillus Calmette-Guerin (BCG) and some monoclonal antibodies. Oncologist A physician who has special training in diagnosing and treating cancer.

The use of high-energy radiation from x-rays, gamma rays, neutrons, protons and other sources to kill cancer cells and shrink tumors. Radiation may come from a machine outside the body (external-beam radiation therapy), or it may come from radioactive material placed in the body near cancer cells (internal radiation therapy or brachytherapy). Systemic radiation therapy uses a radioactive substance, such as a radiolabeled monoclonal antibody, that travels in the blood to tissues throughout the body. Side effects A problem that occurs when treatment affects healthy tissues or organs. Some side effects of cancer treatment are nausea, vomiting, fatigue, pain, decreased blood cell counts, hair loss and mouth sores. Symptom A physical or mental problem that a person experiences that may indicate a disease or condition. Symptoms cannot be seen and do not show up on medical tests.

Surgery

Surgery is the most common treatment for sarcoma, and it may be curative for some people. Chemotherapy, radiation therapy or both may be given before or after surgery to reduce the risk of the cancer coming back.

UW Medicine surgeons who provide care at both SCCA and University of Washington Medical Center perform surgery for our sarcoma patients. They perform more surgeries on adults with sarcoma than surgeons at any other cancer center in the Northwest.

We offer leading-edge options, including limb-sparing surgery, bone transplants and metallic implants, if you need them, and we use minimally invasive techniques, such as laparoscopic surgery (through small "keyhole" incisions), whenever possible.

The exact surgery you need will depend on many factors, including the location and size of your tumor. Your team will explain:

The details of your procedure
The benefits and risks
How to prepare before surgery
What to expect during your recovery and beyond

During surgery, intraoperative ultrasound helps our surgeons better delineate the borders of your tumor to more effectively remove the whole tumor while saving healthy structures nearby. After your surgery, your care team follows evidence-based guidelines to enhance your recovery ("early-recovery after surgery" protocols).

In some situations, a tumor cannot be removed surgically because of its size or location or how aggressive it is. In these cases, a multidisciplinary team can identify another course of treatment to control the sarcoma, reduce its size and relieve pain and other symptoms.

Targeted therapy and immunotherapy

Targeted therapies are another type of medicine that can be used in sarcoma treatment. They target a gene or protein responsible for allowing cancer to grow, they seek out and damage cancer cells, or they prompt your immune system to attack particular cells (also called immunotherapy).

Targeted therapies for sarcoma include:

For bone cancer — denosumab (Xgeva)
For soft tissue sarcoma — olaratumab (Lartruvo) and pazopanib (Votrient)

There are many different types of sarcoma, and other targeted therapies are used to treat particular types, such as:

For gastrointestinal stromal tumors — imatinib (Gleevec), sunitinib (Sutent) and regorafenib (Stivarga), as well as pazopanib
For desmoid tumors — sorafenib (Nexavar)

SCCA has one of the most comprehensive sarcoma immunotherapy research programs anywhere. We have multiple immunotherapy clinical trials, testing a wide range of options, such as T-cell therapy, immune checkpoint inhibitors, vaccines, virus therapies, additional antibody therapies and other medicines that boost the body’s anti-cancer immune response.

Learn more about immunotherapy.

Antibody A protein made by immune system cells and released into the blood. Antibodies defend the body against foreign substances, such as bacteria. Gastrointestinal Refers to the stomach and intestines. Also called GI. Gene The functional and physical unit of heredity passed from parent to offspring. Genes are pieces of DNA, and most genes contain the information for making a specific protein.

A type of treatment that uses drugs or other substances to identify and attack specific types of cancer cells while causing less harm to normal cells. Some targeted therapies block the action of certain enzymes, proteins or other molecules involved in the growth and spread of cancer cells. Other types of targeted therapies help the immune system kill cancer cells, or they deliver toxic substances directly to cancer cells and kill them. Targeted therapy may have fewer side effects than other types of cancer treatment. Most targeted therapies are either small molecule drugs or monoclonal antibodies.

About benign bone and soft tissue tumors

Although some bone tumors are cancerous, most are not. Benign tumors usually do not spread or become life-threatening. However, they can grow aggressively and cause complications such as pain, fracture, or injury to other body parts; or, in rare circumstances, become cancerous.

Because these tumors are rare, many general or even specialized physicians may never see or learn about them, and therefore it is important that you seek a comprehensive evaluation by an expert in bone and soft tissue tumors. Management can range from observing the tumor over time to make sure it does not change to removing it with surgery.

Complex bone and soft tissue reconstruction

Complex limb reconstruction (or “limb salvage surgery”) is a type of orthopedic surgery. These surgeries are complicated and must be done by experts. At SCCA, we use these highly-advanced surgeries to make major repairs to a bone or joint that that has been damaged by tumors of the bones and soft tissues, trauma or failed prior reconstructive procedures. The goal of these surgeries is to keep as much movement in your limb as possible.
