Abstract: Objective To investigate factors impacting on local recurrence in cases of primary retroperitoneal liposarcoma (RPLS) after complete enbloc resection.Methods The clinical data of 47 cases of primary retroperitoneal liposarcoma were retrospectively analyzed.Results 3-year local recurrence rate was 62％.Single and multiple regression analysis showed preoperative needle biopsy,histological subtype,tumor size and capsular invasion were all risk factors related to postoperative local recurrence in primary retroperitoneal liposarcoma undergoing complete resection (P ＜ 0.05).Conclusion Preoperative aspiration biopsy,tumor poor differentiation,large tumor size tumor extracapsular spread all lead to high local recurrence rate after complete resection of primary retroperitoneal liposarcoma.
