The Evolving Landscape of Systemic Therapy for Liposarcoma.

BACKGROUND/

OBJECTIVES

Liposarcoma represents a heterogeneous group of mesenchymal malignancies with distinct molecular profiles and clinical behaviors. While localized disease is managed with surgical resection, advanced or metastatic liposarcoma poses a significant therapeutic challenge due to limited response to traditional cytotoxic chemotherapy. This review summarizes current evidence-based systemic therapies and highlights recent advances in subtype-driven treatment strategies.

METHODS

We review key clinical trials supporting the use of anthracycline regimens, trabectedin, eribulin, and nuclear export inhibition with selinexor, as well as emerging targeted approaches directed at MDM2 and CDK4 amplification. In addition, we discuss the evolving role of immunotherapy, including checkpoint inhibitors and engineered T-cell receptor therapies targeting cancer-testis antigens.

RESULTS

Integrating molecular biology with therapeutic development, we emphasize the importance of histologic and genomic classification in guiding treatment selection and clinical trial design.

CONCLUSION

Continued progress in biomarker-driven strategies and rational combination therapies is expected to further refine personalized treatment approaches and improve outcomes for patients with advanced liposarcoma.
