Soft tissue sarcoma resection volume associated with wound-healing complications

Area of Science:

• Surgical Oncology
• Orthopedic Surgery

Background:

• Limb-salvage surgery is standard for soft tissue sarcomas.
• Primary closure can lead to wound complications, especially with prior radiation or tension.
• Factors influencing wound healing after sarcoma resection require further investigation.

Purpose of the Study:

• To investigate the relationship between the volume of resected soft tissue and the incidence of wound-healing complications.
• To compare outcomes between primary wound closure and primary muscle flap closure in limb-salvage sarcoma surgery.

Main Methods:

• Retrospective review of 108 patients undergoing limb-salvage surgery for soft tissue sarcomas over 17 months.
• Analysis of wound-healing complications in relation to resected tissue volume.
• Comparison of outcomes between primary closure (87 patients) and muscle flap closure (21 patients).

Main Results:

• Patients with wound-healing complications had a significantly greater mean resected tissue volume (919 cm³) compared to those without (456 cm³).
• Primary muscle flap closure involved a mean resected tissue volume (1908 cm³) more than double that of primary closure.
• Higher resected volumes are associated with increased wound complications in primary closure settings.

Conclusions:

• Resected soft tissue volume is a key factor associated with wound-healing complications after limb-salvage surgery.
• Muscle flap closure may be a more suitable option for larger resections to mitigate wound complications.
• Optimizing surgical planning based on expected resection volume can improve patient outcomes.
