Primary intrathoracic liposarcomas: A clinicopathologic and molecular study of 43 cases in one of the largest medical centers of China. (PubMed, Front Oncol)
MPL is the most fatal subtype of this site. Further studies are needed to explore the role of TP53 in the pathogenesis of MPL.

Genomic Predictors of Recurrence Patterns in Localized Soft Tissue Sarcoma Treated With Radiation Therapy. (PubMed, Int J Radiat Oncol Biol Phys)
Our results suggest that somatic tumor mutations may contribute to the risk of local recurrence and distant metastasis in patients treated with RT for localized STS. Additional analysis and validation in larger multi-institutional cohorts will be critical to identify molecular predictors of prognosis and patterns of recurrence.

Expression of FRS2 in atypical lipomatous tumor/well-differentiated liposarcoma and dedifferentiated liposarcoma: an immunohistochemical analysis of 182 cases with genetic data. (PubMed, Diagn Pathol)
This study indicated that FRS2 IHC had relatively good consistency with FRS2 FISH, suggesting that FRS2 immunostaining could be utilized as an additional screening tool for the diagnosis of ALT/WDL/DDL. It must be emphasized that MDM2/CDK4/FRS2 especially MDM2 FISH remains the gold standard and the most recommended method to diagnose this entity.
