radiotherapy or combination chemotherapy may allow tumors to be surgically removed when it would not have been otherwise possible.
Stage IIIB sarcomas of the abdomen, trunk, and head and neck are treated with surgery, often followed by high-dose radiotherapy . If the tumor cannot be completely removed, high-dose radiotherapy combined with chemotherapy may relieve symptoms.
Five-Year Survival 20 to 50 percent
Investigational
• Investigational treatments similar to those for Stage II.
• Intraoperative radiotherapy for Stage IIIA abdominal sarcomas.
Stage IV
This stage is divided into two groups. Tumors of any grade or size that have spread to regional lymph nodes but not to distant sites are Stage IVA. Tumors that have spread to distant sites beyond the lymph nodes draining the area of the cancer (most commonly to the lung) are Stage IVB.
