Abstract    Because of distorted anatomical structure and severe invasion into vascular and surrounding organs in comparison with primary retroperitoneal tumors, the reoperative surgical managements of recurrent retroperitoneal soft tissue tumors are more difficult and risky. Currently, there is no other effective curative treatment method except surgery. Adopting positive surgical method and complete resection as far as possible is still beneficial to the patients.
