Key result
Complete resection of a 12.6 kg retroperitoneal liposarcoma yields no recurrence at one year.
Case Report (n=1)
No
Demonstrates the successful complete resection of a giant retroperitoneal liposarcoma utilizing three-dimensional reconstruction techniques without recurrence at one year.
Supports feasibility of 3D-assisted resection in select giant cases; leaves open durability and generalizability beyond this single report.
Retroperitoneal liposarcoma is a rare soft-tissue malignancy that occurs in middle-aged to older males. In the present case, the tumor was so large that it occupied almost the entire abdominal cavity. With the help of a three-dimensional reconstruction technique, we completely resected the tumor, and the pathology showed that it was a well-differentiated sarcoma, and the tumor did not recur after one year of postoperative follow-up. We present the clinical, radiographic, and pathological findings of such a case.

Zhang et al. (2025) conducted a case report in Retroperitoneal liposarcoma (n=1). Complete surgical resection was evaluated on Tumor recurrence. Complete surgical resection of a 12.6 kg giant well-differentiated retroperitoneal liposarcoma resulted in no tumor recurrence after one year of follow-up.
