Key result
Surgical resection of retroperitoneal liposarcomas demonstrated that well-differentiated subtypes had more favorable outcomes compared to dedifferentiated subtypes, which exhibited higher recurrence risk.
Why the study?
Retroperitoneal liposarcomas often present asymptomatically, leading to delayed diagnosis and challenging management, prompting this exploration of how histological subtypes impact prognosis and recurrence.

This case series highlights that histological subtype, tumor size, and grade are critical prognostic factors in retroperitoneal liposarcomas, necessitating individualized surgical strategies and vigilant surveillance.
Subtype stratification may refine surveillance after retroperitoneal liposarcoma resection; leaves open validation in prospective cohorts.
INTRODUCTION AND IMPORTANCE: Retroperitoneal liposarcomas (RPLPS) are rare soft tissue sarcomas that often present asymptomatically, leading to delayed diagnosis and challenging management. This case series highlights the impact of histological subtypes on prognosis and recurrence. CASE PRESENTATION: Three male patients with recurrent RPLPS were compared. Two cases of well-differentiated liposarcoma (WDLPS) had favorable outcomes with tumor-free margins, despite recurrence in one. The third case, a dedifferentiated liposarcoma (DDLPS), presented with a larger, high-grade tumor requiring extensive resection and had a higher recurrence risk. CLINICAL DISCUSSION: Histological subtype, tumor size, and grade were key prognostic factors. WDLPS showed better outcomes, while DDLPS was more aggressive despite radical surgery. Recurrence remained a major concern, emphasizing the need for early detection and vigilant long-term surveillance. CONCLUSION: This case series underscores the variability in RPLPS presentation and outcomes, highlighting the need for individualized surgical strategies and close follow-up to improve long-term prognosis.

Eghlimi et al. (2025) conducted a case report in Retroperitoneal liposarcoma (n=3). Surgical resection was evaluated on Clinical outcomes and recurrence. Surgical resection of retroperitoneal liposarcomas demonstrated that well-differentiated subtypes had more favorable outcomes compared to dedifferentiated subtypes, which exhibited higher recurrence risk.
