Biopsy techniques for soft tissue and bowel sarcomas

There is overlap in the clinical presentation of benign soft tissue tumors and soft tissue sarcomas. A preoperative sarcoma diagnosis would allow for consideration for neoadjuvant therapy, including preoperative radiation, as well as optimal surgical treatment planning, and patient counseling. Image guided core needle biopsy is a low morbidity, cost-effective, highly accurate approach for obtaining a definitive pathologic diagnosis. Any biopsy approach should minimize the potential for tumor seeding of otherwise uninvolved anatomic structures.
