Morbidity and Mortality after Surgery for Retroperitoneal Sarcoma

Area of Science:

• Oncology
• Surgical Oncology
• Rare Diseases

Background:

• Retroperitoneal sarcoma (RPS) is a rare malignancy comprising 10-15% of soft tissue sarcomas, with over 100 histologic subtypes.
• The Transatlantic RPS Working Group (TARPSWG) was formed by European and North American sarcoma centers to address the rarity of RPS and standardize management.
• Complete resection is the gold standard for RPS, often necessitating multi-visceral resection and potentially en bloc compartmental resections to minimize local recurrence.

Purpose of the Study:

• To review factors contributing to perioperative complications in retroperitoneal sarcoma surgery.
• To outline strategies for mitigating poor surgical outcomes in patients with RPS.

Main Methods:

• Literature review focusing on perioperative complications and management strategies for RPS.
• Analysis of current guidelines and emerging evidence regarding surgical approaches and patient optimization.

Main Results:

• Complete tumor resection, including microscopic disease, is crucial for optimal outcomes in RPS.
• En bloc compartmental resections may reduce local recurrence but require careful consideration of associated morbidity.
• Preoperative patient optimization (nutrition, pre-habilitation) and enhanced recovery protocols are key to mitigating postoperative complications.

Conclusions:

• Managing retroperitoneal sarcoma demands a multidisciplinary approach, balancing aggressive resection with complication mitigation.
• Referral to high-volume sarcoma centers and adherence to enhanced recovery protocols are vital for improving patient outcomes.
• Further research and collaboration through groups like TARPSWG are essential for advancing RPS treatment strategies.
