Background and Objectives: Liposarcoma (LPS) is a malignant mesenchymal tumor and the most common soft tissue sarcoma. Four different subtypes are described: well differentiated (WD) LPS or atypical lipomatous tumor (ALT), dedifferentiated (DD) LPS, myxoid LPS, and pleomorphic LPS (PLS). The objective of the study was to investigate prognostic factors and clinical outcome of liposarcoma.Methods: We retrospectively examined the clinico-pathological features of a series of 307 patients affected by Liposarcoma at a mean follow-up of 69 months (range 6-257). ALT/WD LPS were analyzed separately. The influence of site, size, type of presentation, grading, histotype and local recurrence on local and systemic control and survival was assessed.Results: The statistical analysis indicated that only surgical margins represented a significant prognostic factor for local recurrence in ALT/WD LPS (P = 0.0007) and other subtypes of LPS (P = 0.0055). In myxoid, PLS and DD LPS, significant prognostic factors for metastasis free survival (MFS) were surgical margins (P = 0.0009), size of the tumor (P = 0.0358), histology (P = 0.0117) and local recurrence (P = 0.0015). In multivariate analysis, surgical margins (0.0180), size (0.0432) and local recurrence (0.0288) correlated independently with MFS. Margins (P = 0.0315), local recurrence (P = 0.0482) and metastases (P < 0.0001) were prognostic factors for overall survival (OS).Conclusion: Marginal surgery can be an accepted treatment for ALT/WD LPS. In other liposarcoma subtypes (Myxoid, DD, PLS) wide or radical surgery is recommended as the margins significantly influence local recurrence-free survival (LRFS), metastasis-free survival (MFS) and overall survival (OS). Local recurrence and metastases were significant prognostic factors for OS. [ABSTRACT FROM AUTHOR] |
