[Retroperitoneal sarcoma: report of 6 cases]

Area of Science:

• Oncology
• Surgical Pathology

Context:

• Retroperitoneal soft tissue sarcomas (RPS) are uncommon malignancies.
• Delayed diagnosis is frequent due to nonspecific symptoms.
• Surgical resection is the primary treatment, achievable in 38-75% of cases.

Purpose:

• To review clinical characteristics, diagnosis, and outcomes of retroperitoneal soft tissue sarcomas.
• To highlight the role of CT scans in diagnosis and surgical planning.

Summary:

• A retrospective review of six RPS cases revealed a mean 5-month diagnostic delay.
• Common symptoms included abdominal mass and pain; compression signs appeared late.
• Histological types included liposarcoma, rhabdomyosarcoma, and fibrosarcoma.
• Complete resection was achieved in 4 cases; recurrence occurred in 2 liposarcomas.

Impact:

• RPS are prone to locoregional relapse and metastasis.
• Prognosis is influenced by histological type, tumor grade, and completeness of surgical resection.
• Early diagnosis and complete resection are vital for improving patient outcomes.
