Long-term outcomes of computer navigation-assisted resection for primary pelvic sarcomas

This study shows that computer navigation-assisted surgery improves the ability to achieve negative bone margins for primary pelvic sarcomas and has better DSS at long-term follow-up. Obtaining adequate soft-tissue margins remains a challenge, and our results show navigation assistance did not result in significant soft-tissue margin improvement. No function improvement was found, and further research is warranted to focus on precise resection and the important preservation of normal structures.
