Abstract
Sarcomas represent a heterogeneous group of malignancies of mesenchymal origin that can arise from any anatomical site. Of soft tissue sarcomas, retroperitoneal sarcoma represents approximately 15-20%. They usually grow more than 20 cm and unlike epithelial solid tumors, retroperitoneal sarcomas infiltrate several larger viscera and neurovascular structures, so surgery is often of high complexity. Radiation therapy and chemotherapy play an adjuvant or neoadjuvant role, but surgery remains the basis of treatment for resectable retroperitoneal sarcomas.
