• The use of various special types of radiotherapy beams.
• Radiotherapy after limb-sparing surgery.
Stage III
These are poorly differentiated or undifferentiated (high-grade) tumors that have not spread to nearby lymph nodes or to distant sites. This stage is further divided into IIIA and IIIB according to the size of the primary tumor .
Standard Treatment Stage IIIA sarcomas are highly treatable and often curable but have an increased chance of metastatic spread. The standard treatment is surgery with radiotherapy or chemotherapy , or sometimes all three.
Sarcomas of the arms or legs are treated in a similar way to Stage II tumors. Sarcomas of the abdomen, trunk, and head and neck are treated with surgery followed by high-dose radiation. Radiotherapy is also sometimes given before surgery, and high-dose radiation sometimes combined with chemotherapy is given if the tumor cannot be completely removed surgically.
Stage IIIB sarcomas are treated much like Stage II and IIIA tumors. Because these tumors are larger, however, in many cases of tumors of the arms or legs amputation will be necessary. In some cases, preoperative
