PDQ is a computer system that gives up-to-date information on cancer and its prevention, detection, treatment, and supportive care. It is a service of the National Cancer Institute (NCI) for people with cancer and their families and for doctors, nurses, and other health care professionals.
To ensure that it remains current, the information in PDQ is reviewed and updated each month by experts in the fields of cancer treatment, prevention, screening, and supportive care. PDQ also provides information about research on new treatments (clinical trials), doctors who treat cancer, and hospitals with cancer programs. The treatment information in this summary is based on information in the PDQ summary for health professionals on this cancer.
PDQ can be used to learn more about current treatment of different kinds of cancer. You may find it helpful to discuss this information with your doctor, who knows you and has the facts about your disease. PDQ can also provide the names of additional health care professionals who specialize in treating patients with cancer.
Before you start treatment, you also may want to think about taking part in a clinical trial. PDQ can be used to learn more about these trials. A clinical trial is a research study that attempts to improve current treatments or finds information on new treatments for patients with cancer. Clinical trials are based on past studies and information discovered in the laboratory. Each trial answers certain scientific questions in order to find new and better ways to help patients with cancer. Information is collected about new treatments, their risks, and how well they do or do not work. When clinical trials show that a new treatment is better than the treatment currently used as "standard" treatment, the new treatment may become the standard treatment. Listings of current clinical trials are available on PDQ. Many cancer doctors who take part in clinical trials are listed in PDQ.
To learn more about cancer and how it is treated, or to learn more about clinical trials for your kind of cancer, call the National Cancer Institute's Cancer Information Service. The number is 1-800-4-CANCER (1-800-422-6237); TTY at 1-800-332-8615. The call is free and a trained information specialist will be available to answer cancer-related questions.
PDQ is updated whenever there is new information. Check with the Cancer Information Service to be sure that you have the most up-to-date information.
Adult soft tissue sarcoma is a disease in which cancer (malignant) cells are found in the soft tissue of part of the body. The soft tissues of the body include the muscles, connective tissues (tendons), vessels that carry blood or lymph, joints, and fat.
A lump or swelling in part of the body may appear if a person has a soft tissue sarcoma. The lump may not be painful. If there are symptoms, a doctor may cut out a piece of tissue from the swollen area. This is called a biopsy. The tissue will be looked at under a microscope to see if there are any cancer cells. A patient may need to go to the hospital for this test.
The chance of recovery (prognosis) and choice of treatment depend on the size and stage of the cancer (how far the cancer has spread), and the patient's age and general health.
Once adult soft tissue sarcoma is found, more tests will be done to find out if cancer cells have spread to other parts of the body. This testing is called staging. A doctor needs to know the stage of the disease to plan treatment. Unlike most other cancers, the size of a soft tissue sarcoma is not as important as how the cancer cells look under a microscope. The more different the cancer cells look from normal cells, the higher the stage. The following stages are used for adult soft tissue sarcoma:
The cancer cells look either very much like or somewhat different from normal cells (well-differentiated or moderately well-differentiated). The cancer is either near the surface or deep and is less than 5 centimeters in size (about 2 inches), but it has not spread to lymph nodes or other parts of the body (lymph nodes are small bean-shaped structures that are found throughout the body; they produce and store infection-fighting cells).
The cancer cells look either very much like or somewhat different from normal cells (well-differentiated or moderately well-differentiated). The cancer is near the surface and more than 5 centimeters in size, but it has not spread to lymph nodes or other parts of the body.
The cancer cells look either very much like or somewhat different from normal cells (well-differentiated or moderately well-differentiated). The cancer is deep and more than 5 centimeters in size, but it has not spread to lymph nodes or other parts of the body.
The cancer cells look very different from normal cells (poorly differentiated or undifferentiated). The cancer is either near the surface or deep and is less than 5 centimeters in size, but it has not spread to lymph nodes or other parts of the body.
The cancer cells look very different from normal cells (poorly differentiated or undifferentiated). The cancer is near the surface and is more than 5 centimeters in size, but it has not spread to lymph nodes or other parts of the body.
The cancer cells look very different from normal cells (poorly differentiated or undifferentiated). The cancer is deep and is more than 5 centimeters in size, but it has not spread to lymph nodes or other parts of the body.
The cancer may have spread to lymph nodes in the area or may have spread to other parts of the body, such as the lungs, head, or neck.
Recurrent disease means that the cancer has come back (recurred) after it has been treated. It may come back in the tissues where it first started, or it may come back in another part of the body.
There are treatments for all patients with adult soft tissue sarcoma. Three kinds of treatment are used:
Radiation therapy uses x-rays or other high-energy rays to kill cancer cells and shrink tumors. Radiation may come from a machine outside the body (external-beam radiation therapy) or from putting materials that produce radiation (radioisotopes) through thin plastic tubes in the area where the cancer cells are found (internal radiation therapy).
Chemotherapy uses drugs to kill cancer cells. Chemotherapy may be taken by pill, or it may be put into the body by a needle in a vein or muscle. Chemotherapy is called a systemic treatment because the drug enters the blood stream, travels through the body, and kills cancer cells throughout the body. Chemotherapy that is given after surgery when no cancer cells can be seen is called adjuvant chemotherapy. In soft tissue sarcoma, chemotherapy is sometimes injected directly into the blood vessels in the area where the cancer is found. This treatment is called regional chemotherapy.
Chemotherapy and/or radiation therapy may be used to shrink the cancer so it can be removed without taking off an entire arm or leg.
Treatments for adult soft tissue sarcoma depend on the stage of the disease, and the patient's age and general health.
Patients may consider standard therapy, because of its effectiveness in past studies, or participation in a clinical trial. Not all patients are cured with standard therapy, and some standard treatments may have more side effects than are desired. For these reasons, clinical trials are designed to find better ways to treat cancer patients and are based on the most up-to-date information. For more information about clinical trials, call the Cancer Information Service at 1-800-4-CANCER (1-800-422-6237); TTY at 1-800-332-8615.
Treatment may be one of the following:
2. Surgery with radiation therapy, before or after the surgery.
3. High-dose radiation therapy followed by surgery and radiation therapy.
2. Radiation therapy followed by surgery.
Treatment may be one of the following:
2. Surgery to remove the cancer followed by radiation therapy.
3. Radiation therapy alone.
4. Radiation therapy and/or chemotherapy before surgery, possibly followed by radiation therapy.
If the cancer has spread to the lymph nodes, treatment may be one of the following:
2. Radiation therapy before and after surgery to remove the cancer and lymph node dissection.
3. A clinical trial of surgery and/or radiation therapy followed by chemotherapy
2. Surgery to remove the primary cancer.
3. Surgery to remove the primary cancer followed by radiation therapy.
4. Radiation therapy, possibly followed by chemotherapy.
2. Chemotherapy to reduce the pain and discomfort caused by the cancer.
Treatment depends on the kind of treatment the patient had before. Treatment may be one of the following:
2. Surgery to remove the cancer followed by radiation therapy.
3. Chemotherapy alone.
