Precision-Oriented Reconstruction After Spinal Sarcoma Resection: Integrating Surgical Strategy, Biologic Risk, and...

Area of Science:

• Oncology
• Orthopedic Surgery
• Reconstructive Surgery

Background:

• Primary spinal sarcomas present complex reconstruction challenges due to varied biology and compromised host environments.
• Factors like radiation, systemic therapy, and prior surgery significantly impact reconstructive success.
• A precision-medicine approach is needed for tailored spinal reconstruction.

Purpose of the Study:

• To reframe post-resection spinal reconstruction through a precision-medicine lens.
• To identify key determinants of reconstructive success in spinal sarcoma patients.
• To propose a framework for guiding reconstructive strategy selection.

Main Methods:

• A structured literature review of PubMed and Scopus databases (2000-2026).
• Searches focused on spinal sarcoma reconstruction, radiation, fusion, biologic reconstruction, and emerging technologies.
• Analysis of factors influencing reconstructive environment quality.

Main Results:

• Tumor grade, radiation, and systemic therapy timing are critical for reconstructive success.
• Vascularized bone grafts offer reliable fusion in compromised hosts.
• A precision-oriented reconstructive ladder framework is proposed, with potential for hybrid constructs.

Conclusions:

• Individualized strategies based on tumor biology and host environment are essential for durable spinal sarcoma reconstructions.
• The proposed framework requires prospective validation.
• Standardized outcomes, registries, and stratified analyses are needed to advance the field.
