Background and Objectives: Primary mesenteric liposarcoma (LPS) is an exceptionally rare malignancy, with most literature data limited to isolated case reports or small series. This papers aims to evaluate the clinicopathological features, treatment outcomes, and prognostic factors in patients with mesenteric LPS. Materials and Methods: Thirteen patients diagnosed with primary mesenteric LPS between 2010 and 2022 were retrospectively analyzed. Data included demographics, tumor location, histological subtype, surgical treatment, recurrence, and survival. Results: The median age was 56 years (range, 22-74), with a slight male predominance (53.8%). Most tumors arose from the small bowel (53.8%) and colonic (38.5%) mesenteries, with one involving the gastric mesentery. The predominant histological subtypes were myxoid (46.1%) and dedifferentiated (23.1%). R0 resection was achieved in 76.9% of patients. During a median follow-up of 55.2 months, nine patients (69.2%) developed recurrence. Mortality was higher in patients with dedifferentiated LPS (66.7%) than in those with myxoid LPS (40%). Five-year survival rate was 100% in patients without recurrence and 28.6% in those with recurrence (p = 0.112, not significant). Patients who received adjuvant chemoradiotherapy suggested longer survival (110.7 vs. 46.2 months; p = 0.620). Conclusions: This 12-year study highlights the aggressive nature of mesenteric LPS, particularly the dedifferentiated subtype which showed the poorest prognosis. Complete resection remains the primary treatment; however, it has high recurrence rates. To diminish the catastrophic poor results of the postoperative period, multidisciplinary treatment strategies become a keystone.
