Objective To explore the correlation of S100 protein with the prognosis of patients with primary retroperitoneal liposarcoma. Methods Analyzed the clinical data about 108 patients with primary retroperitoneal liposarcoma managed with surgery from January 2009 to June 2014. All patients were followed up. Patients were divided into S100-positive group(58 patients) and S100-negative group (50 patients) according to the immunohistochemical staining results. The overall survival time and all clinical data between two group were compared. Results All patients with primary retroperitoneal liposarcoma received radical surgical resection for the first time. The overall 5-year recurrence rate were 88.9%(96/108), and the median recurrence time was 32.7 months. The 1-year, 2-year, and 5-year recurrence rates of the S100- positive group were 25.9% (15/58), 53.4% (31/58), 96.6% (56/58), respectively, and the median recurrence time were 26.2 mouths. The 1-year, 2-year, and 5-year recurrence rates of the S100-negative group were 10.0%(5/50), 36%(18/50), 80.0%(40/50) and the median recurrence time were 40.0 mouths. Log-rank test showed that S100 protein expression was significantly associated with postoperative recurrence rates (c2=9.931, P=0.002) and survival time (c2=4.571, P = 0.033). The difference between gender, age, removal of the joint organs and tumor size showed no statistical significance on disease special survival (P>0.05). Cox regression analysis showed that S100 protein expression (OR=1.582, 95%CI:1.005-2.491) and histologic subtype (OR=1.531, 95%CI: 1.254-1.870) were independent risk factors of the prognosis of primary retroperitoneal liposarcoma patients. Conclusions S100 protein played a critical role in retroperitoneal liposarcoma carcinogenesis and its expression may be used as a potential survival predictor in patients with primary retroperitoneal liposarcoma.
