Multiply recurrent retroperitoneal liposarcoma.

Retroperitoneal liposarcomas (RPLPS) are rare tumors that represent at least 50% of all retroperitoneal sarcomas. Surgical resection remains the standard of care. Unfortunately, many RPLPS patients will develop a local recurrence and subsequently die in the absence of distant metastasis. This review outlines the factors that predict local recurrence and influence the management of first and subsequent multiply recurrent RPLPS.
