UC Davis Comprehensive Cancer Center offers comprehensive, multidisciplinary care for young and adult patients with bone and soft-tissue sarcomas — cancers that affect bone, muscle, cartilage, blood vessels and other connective tissues in the body. Sarcoma treatment at UC Davis Cancer Center is aimed at preservation of critical functions, prevention of disease recurrence and optimization of quality of life.

Your team of cancer specialists will include experts in medical oncologysurgical and orthopaedic oncologyplastic surgery, and vascular surgery. Pre-operative and post-operative patient care also requires close coordination with radiation oncologymedical oncology and radiology.

Soft tissue sarcomas represent challenging malignancies for which care is best delivered at specialized, high-volume referral centers, such as UC Davis Comprehensive Cancer Center. Patients frequently have large tumors that are technically challenging to remove with surgery, and the pre- and post-operative care for these patients requires careful coordination among multiple disciplines.

UC Davis Comprehensive Cancer Center delivers high quality care to patients with sarcoma from Northern California, Southern California, Western Nevada and Oregon.

More about sarcoma

Dr. Canter © UC RegentsSurgery is the most common treatment for adult soft tissue sarcoma, and sometimes the only treatment needed. Specific surgical procedures may include:

Wide local excision: Removal of the tumor along with a cuff or “margin” of normal tissue around it.

Limb-sparing surgery: This approach involves a more extensive removal of the tumor and surrounding soft tissue in an arm or leg, but remains able to avoid amputation, so the use and appearance of the limb are preserved. Critical structures such as nerves, blood vessels, and bone may be removed and replaced with a graft using tissue and bone taken from another part of the patient's body, or with artificial implants designed to adapt to the body.

Amputation: Surgery to remove part or all of a limb or appendage, such as an arm or leg. Since survival rates are comparable when limb-sparing surgery is combined with radiotherapy, as compared to amputation, most specialized centers currently reserve amputation for rare cases of sarcoma (about 3-5 percent) where tumors are very advanced and it is not possible to perform a complete tumor resection without severely compromising limb function.

Radiation therapy or chemotherapy: These may be given before (neoadjuvant therapy) or after (adjuvant therapy) surgery to remove the tumor. When given before surgery, the therapy will shrink the tumor, reducing the amount of tissue that needs to be removed during surgery. When given after surgery, radiation therapy or chemotherapy will kill any remaining cancer cells.

Radiation therapy: This treatment uses high-energy X-rays or other types of radiation to kill cancer cells or keep them from growing. There are two types of radiation therapy:

  • External radiation therapy uses a machine outside the body to send radiation toward the cancer. One type of therapy, called fast neutron radiation therapy, aims neutrons (tiny, invisible particles) at the cancer cells to kill them. Using higher-energy radiation than X-ray radiation therapy allows the same amount of radiation to be given in fewer treatments.
  • Internal radiation therapy uses a radioactive substance sealed in needles, seeds, wires, or catheters, which are placed directly into or near the cancer.

Chemotherapy: This treatment uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. When chemotherapy is taken by mouth or injected into a vein or muscle, the drugs enter the bloodstream and can reach cancer cells throughout the body (systemic chemotherapy). When chemotherapy is placed directly into the spinal column, an organ, or a body cavity such as the abdomen, the drugs mainly affect cancer cells in those areas (regional chemotherapy).

Targeted therapy: This treatment uses drugs or other substances to find and attack specific cancer cells without harming normal cells. Imatinib (Gleevec) is a type of targeted therapy called a tyrosine kinase inhibitor used for abdominal tumors known as GI stromal tumors (GISTs). It finds and blocks an abnormal protein on cancer cells that causes them to divide and grow.
