Liposarcoma: State of the Art-A Scoping Review

Background/Objectives: The most common soft tissue sarcomas in adults are liposarcomas, a heterogeneous group of malignant tumors. A structured literature search was conducted to better understand the clinical-imaging aspects and molecular behavior underlying the therapeutic approach. Methods: A scoping review was performed according to the PRISMA-ScR guidelines. Searches were conducted in MEDLINE, Web of Science Core Collection, and Google Scholar for the period of 1 January 2016-27 March 2026. Studies that addressed liposarcomas and their subtypes were included. Data were extracted descriptively and synthesized narratively. Results: We identified 113 studies that met the inclusion and exclusion criteria. Most studies have focused on a subtype of liposarcomas or on aspects such as clinical, imaging, histopathological, molecular, therapeutic, or prognostic features. The collected data identify, in each case, the need to develop new techniques useful for their identification and deeper molecular analysis. These needs arise from the need to improve treatment and to provide better prognosis, especially in rare or high-grade subtypes. Conclusions: The heterogeneity of these tumors requires the provision of a diagnosis that takes into account all possible instruments: clinical, imaging, and histo-molecular. Therefore, further research and translational medicine are needed to discover new pathogenic mechanisms in order to develop individualized therapies that increase quality of life.
