Objective To understand the pathogenesis and the research progress of comprehensive treatment of primary retroperitoneal liposarcoma (PRLPS) and to provide evidence for clinical diagnosis and treatment.Method The recent literatures on the pathological classification, pathogenesis of PRLPS, and comprehensive treatment including the surgery, radiotherapy, chemotherapy, and molecular targeted therapy were reviewed.Results The pathological types of PRLPS were highly differentiated, dedifferentiated, mucoid/round cell, polymorphic, and mixed. The main molecular pathogenesis was the synergistic effect of MDM2 with related genes, abnormal expressions of c-myc gene and microRNAs, Prune-nm23-H1 mechanism, and abnormal protein products of FUS-CHOP fusion gene which regulated the growth of tumor. The treatment of PRLRS included the radical resection, extended resection, and palliative resection combined with radiotherapy, chemotherapy, and molecular targeted therapy.Conclusions PRLPS is a rare malignant tumor with high recurrence rate, but early diagnosis and treatment are difficult. With the further study of the molecular mechanism of PRLPS, the treatment of PRLPS has been transformed into a comprehensive treatment based on surgery, adjuvant radiotherapy and chemotherapy, and molecular targeted therapy.
