Summary
This phase III trial is studying observation to see how well a risk based treatment strategy works in patients with soft tissue sarcoma. In the study, patients are assigned to receive surgery +/- radiotherapy +/- chemotherapy depending on their risk of recurrence. Sometimes, after surgery, the tumor may not need additional treatment until it progresses. In this case, observation may be sufficient. Radiation therapy uses high-energy x-rays to kill tumor cells. Drugs used in chemotherapy, such as ifosfamide and doxorubicin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving chemotherapy and radiation therapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. Giving these treatments after surgery may kill any tumor cells that remain after surgery.

- Dermatofibrosarcoma protuberans meeting both of the following criteria:

- Non metastatic disease

- Tumor must be grossly resected prior to study enrollment

- Embryonal sarcoma of the liver

- Unclassified STS that is too undifferentiated to be placed in a specific
pathologic category (undifferentiated STS or STS NOS)

- Gross resection of the primary tumor ≤ 42 days prior to enrollment required except if
any of the following circumstances apply:

- Non metastatic high-grade tumor > 5 cm in maximal diameter and gross or
microscopic residual tumor is anticipated after resection

- Tumor of either high- or- low-grade that cannot be grossly excised without
unacceptable morbidity

- High-grade tumor with metastases

- Patients with metastatic low-grade tumor whose disease is amenable to gross
resection at all sites must undergo gross resection of all sites prior to
study entry

- Patients with a tumor recurrence after a gross total resection are not eligible

- Tumors arising in bone are not eligible

- Patients with epithelioid sarcoma, clear cell sarcoma, or clinical or radiologic
evidence of regional lymph node enlargement must undergo sentinel lymph node biopsies
or lymph node sampling to confirm the status of regional lymph nodes* NOTE: *Except in
cases where the study radiologist reviews the imaging and indicates that a biopsy is
not needed to confirm that the patient has lymph node involvement.

- If lymph node biopsies are positive for tumor (or the lymph nodes are classified
as positive by the study radiologist), formal lymph node dissection must be done
at the time of definitive surgery(prior to study entry for patients assigned to
study regimen C)

metastatic tumor if all metastases are < 1 cm in maximal diameter (except in cases
where the study radiologist reviews the imaging and indicated that a biopsy is not
needed to confirm that the patient has metastatic disease)
