Surgical morbidity in retroperitoneal sarcoma resection.

Resection of retroperitoneal sarcoma (RPS) typically involves multivisceral resection. The morbidity of RPS resection has decreased over time despite widespread adoption of radical resection. Certain patterns of resection are associated with higher complication rates and elderly patients are at increased risk of morbidity. Administration of preoperative radiotherapy does not increase morbidity, but intraoperative and brachytherapy techniques are associated with heightened toxicities. Long-term functional outcomes and quality of life scores after RPS resection are acceptable.
