The National Comprehensive Cancer Network (NCCN) guidelines for intra-abdominal sarcomas recommend evaluation and management prior to initiation of therapy by a multidisciplinary team with expertise and experience in sarcoma. A pretreatment chest/abdominal/pelvic CT scan with intravenous contrast, with or without MRI, is also indicated.

Pre-resection biopsy is not necessarily required, based on degree of suspicion of other malignancies. Biopsy is required for patients receiving preoperative radiation therapy (RT) or chemotherapy, because the treatment regimen is selected on the basis of the histologic subtype. [1]
