Optimizing Morbidity in Unplanned Soft Tissue Sarcoma Excisions: Should We Skip the Reconstructive Ladder?

Area of Science:

• Oncology
• Surgical Oncology
• Reconstructive Surgery

Background:

• Soft tissue sarcomas (STSs) are rare malignancies, often requiring secondary tumor bed excisions (TBEs) after initial unplanned excisions.
• Reconstructive outcomes following TBEs are not well-understood, necessitating further investigation to guide patient care.

Purpose of the Study:

• To compare reconstructive outcomes between initial mass excisions (MEs) and secondary tumor bed excisions (TBEs) for soft tissue sarcomas.
• To identify factors influencing postoperative complications in STS tumor bed reconstructions.

Main Methods:

• Retrospective cohort study comparing patients undergoing ME versus TBE for STS.
• Categorization of reconstructive approaches into simple (e.g., primary closure, skin grafts) and advanced (e.g., flaps).
• Comparison of postoperative outcomes including complications, recurrence, and mortality.

Main Results:

• TBEs with simple reconstruction had higher rates of overall and major complications compared to MEs.
• MEs with simple reconstruction showed higher rates of minor complications than TBEs.
• Simple reconstruction of TBEs was associated with significantly higher odds of major complications (90%) and reoperation (180%) compared to simple reconstruction of MEs.

Conclusions:

• Tumor bed excisions (TBEs) are associated with increased major complications, challenging the assumption that simpler reconstruction suffices.
• Advanced reconstructive techniques should be considered for TBEs, even when they appear suitable for simpler methods, to improve outcomes.
