There are different types of treatment for patients with osteosarcoma or malignant fibrous histiocytoma (MFH) of bone.

Different types of treatment are available for children with osteosarcoma or malignant fibrous histiocytoma (MFH) of bone. Some treatments are standard (the currently used treatment), and some are being tested in clinical trials. A treatment clinical trial is a research study meant to help improve current treatments or obtain information on new treatments for patients with cancer. When clinical trials show that a new treatment is better than the standard treatment, the new treatment may become the standard treatment.

Because cancer in children is rare, taking part in a clinical trial should be considered. Some clinical trials are open only to patients who have not started treatment.

Children with osteosarcoma or MFH should have their treatment planned by a team of health care providers with expertise in treating cancer in children.

Treatment will be overseen by a pediatriconcologist, a doctor who specializes in treating children with cancer. The pediatric oncologist works with other pediatric health care providers who are experts in treating osteosarcoma and MFH and who specialize in certain areas of medicine. These may include the following specialists:

• Orthopedic surgeon.
• Radiation oncologist.
• Rehabilitation specialist.
• Pediatric nurse specialist.
• Social worker.
• Psychologist.

Some cancer treatments cause side effects months or years after treatment has ended.

Side effects from cancer treatment that begin during or after treatment and continue for months or years are called late effects. Late effects of cancer treatment may include the following:

• Physical problems.
• Changes in mood, feelings, thinking, learning, or memory.
• Second cancers (new types of cancer).

Some late effects may be treated or controlled. It is important to talk with your child's doctors about the effects cancer treatment can have on your child. (See the PDQ summary on Late Effects of Treatment for Childhood Cancer for more information).

Four types of standard treatment are used:

Surgery

Surgery to remove the entire tumor will be done when possible. Chemotherapy may be given first, to make the tumor smaller so less tissue and bone needs to be removed. This is called neoadjuvant chemotherapy.

The following types of surgery may be done:

• Wide local excision: Surgery to remove the cancer and some healthy tissue around it.
• Limb-sparing surgery: Removal of the tumor in a limb (arm or leg) without amputation, so the use and appearance of the limb is saved. Most patients with osteosarcoma in a limb can be treated with limb-sparing surgery. The tumor is removed by wide local excision. Tissue and bone that are removed may be replaced with a graft using tissue and bone taken from another part of the patient's body, or with an implant such as artificial bone. If a fracture is found at diagnosis or during chemotherapy before surgery, limb-sparing surgery may still be possible in some cases. If the surgeon is not able to remove all of the tumor and enough healthy tissue around it, an amputation may be done.
• Amputation: Surgery to remove part or all of an arm or leg. This may be done when it is not possible to remove all of the tumor in limb-sparing surgery. The patient may be fitted with a prosthesis (artificial limb) after amputation.
• Rotationplasty: Surgery to remove the tumor and the knee joint. The part of the leg that remains below the knee is then attached to the part of the leg that remains above the knee, with the foot facing backward and the ankle acting as a knee. A prosthesis may then be attached to the foot.
