Complete surgical resection of a giant retroperitoneal liposarcoma with multi-organ involvement can be successfully performed with no early recurrence.
BACKGROUND: Retroperitoneal liposarcoma (RPLPS) is a relatively rare disease. Liposarcomas vary in size, but sizeable RPLPS larger than 30 cm in diameter are very rare, and their diagnosis and treatment present significant challenges. CASE PRESENTATION: We report a 58-year-old male patient who was admitted to the hospital with an increased abdominal circumference and was later diagnosed with a giant RPLPS. The liposarcoma was found to adhere to the right kidney and the entire ureter, invading the ascending colon. The patient underwent complete combined surgical resection. The tumor was removed intact, measured 55.0 cm × 30.0 cm × 18.0 cm, and weighed 19.8 kg. Histopathologic analysis revealed well-differentiated liposarcoma (WDLPS). The patient was successfully discharged from the hospital and followed up for 6 months with no signs of recurrence. CONCLUSION: RPLPS is a rare tumor with atypical clinical presentation. Surgery remains the most effective method of treatment for retroperitoneal sarcomas, with complete removal if there is local invasion. Preoperative examination, including three-dimensional (3D) reconstruction, is essential for surgical success. The role of adjuvant radiotherapy or chemotherapy remains controversial. However, clinicians should not rule them out as viable options.
Sun et al. (Thu,) conducted a case report in Giant retroperitoneal liposarcoma (n=35). Surgical resection was evaluated on Recurrence. Complete surgical resection of a 19.8 kg giant retroperitoneal liposarcoma, aided by 3D reconstruction, was successfully performed with no signs of recurrence at 6 months.
