ABSTRACT
Purpose This study was to investigate the clinical significance of MDM2 protein expression and gene amplification in atypical lipomatous tumour/well-differentiated liposarcoma (ALT/WDL).Methods MDM2 protein expression and gene amplification were detected by immunohistochemistry of EliVision two-step method and fluorescence in situ hybridization (FISH) in 58 cases of ALT/WDL.Results Immunohistochemical staining showed that the positive rate of MDM2 was 79.3%,MDM2 gene amplification rate by FISH assay was 96.5%.There was statistically significant differences between immunohistochemistry and FISH (P < 0.05).Conclusion MDM2 protein expression and MDM2 gene amplification provide the basis for diagnosis of ALT/WDL.However,a positive rate of MDM2 by immunohistochemistry is nearly 80%,so we recommand to carry out immunohistochemical MDM2 protein detection in most conditions without FISH which can help in the diagnosis of most cases of ALT/WDL.
