Eligibility Criteria
DISEASE CHARACTERISTICS:
Histologically confirmed soft tissue sarcoma meeting the following criteria:
Lesion originates in extremity
Upper extremity lesions may occur from the medial border of the scapula to tumors as far distal as the finger tips
- No lesions of the chest wall arising adjacent to the scapula but not originating in the shoulder bone
- Lower extremity regions include hip girdle tumors commencing at the iliac crest, excluding lesions arising from within the pelvis, and extends to include lesions as far distal as the toes
- Imaging and pathology from first surgery are required
Has undergone surgical resection of the tumor within the past 12 weeks
- No macroscopic tumor in situ after surgery
- Microscopically irradical surgical margin allowed
- Excisional biopsy with positive margins or other inadequate surgery (macroscopically involved margins) allowed only after further definitive re-excision
- Positive margins and no further surgery possible except amputation or major functional loss allowed provided no macroscopic residual disease is present
- Local recurrence within 3 months of prior surgery (or other treatment) allowed provided patient undergoes subsequent re-excision
No diagnosis of any of the following:
- Rhabdomyosarcoma (alveolar or embryonal)
- Primitive neuroectodermal tumor
- Soft tissue Ewing's sarcoma
- Extraskeletal osteosarcoma
- Aggressive fibromatosis (desmoid tumors)
- Dermatofibrosarcoma protuberans
- Gorlin's syndrome
- No regional nodal disease or unequivocal distant metastasis
PATIENT CHARACTERISTICS:
- Not pregnant or nursing
- Negative pregnancy test
- Fertile patients must use effective contraception during and for 3 months after completion of study treatment
- No other major medical illness that would preclude study treatment
- No other malignancy except adequately treated nonmelanomatous carcinoma of the skin or in situ carcinoma of the cervix

Research arm
Radiotherapy Conventional treatment arm A total of 33 fractions each of 2Gy should be given once a day for 5 days per week over 6 weeks and 3 days in week 7, totalling 66Gy. The first 50 Gy in 25 fractions will be given to CTV1 and subsequent 16 Gy in 8 fractions will be delivered to CTV2.
Radiotherapy Research arm A total of 33 fractions each of 2Gy should be given once a day for 5 days per week over 6 weeks and 3 days in week 7, totalling 66Gy. The 66Gy in 33 fractions will be delivered to CTV2 alone. No attempt will be made to include drain/biopsy sites or the surgical scar.
