Abstract    Surgical resection remains the mainstay of treatment for extremity soft tissue sarcomas (STS). With the development of modern surgical technologies and theories, the surgical treatment of STS has been developed into a multidisciplinary model which mainly includes limb-sparing resection and functional reconstruction. Wide local excision with at least 1 cm of normal tissue around the tumor is the current surgical goal. Marginal resection combined with adjuvant therapy could be used in case of proximity to vital structures. Removal of neurovascular bundles or bony structures necessitates reconstruction in limb-sparing surgeries. Amputation should be taken into consideration when a non-functional residual limb will be left after massive resection of neurovascular bundles and surrounding soft tissue.
