Massive chest wall resection and reconstruction for malignant disease

Area of Science:

• Thoracic surgery
• Surgical oncology
• Neoplasm research

Background:

• Malignant chest wall tumors are rare and aggressive.
• Wide-free margin resection is critical for prognosis.
• Massive chest wall resection and reconstruction are frequently required.

Purpose of the Study:

• To investigate correlations between tumor characteristics, surgical approach, and patient outcomes.
• To analyze short- and long-term results of chest wall tumor resection and reconstruction.
• To identify factors influencing recurrence and survival in malignant chest wall neoplasms.

Main Methods:

• Retrospective case series of 20 patients (2006-2014).
• Detailed recording of tumor size, histology, resection extent, and reconstruction techniques.
• Analysis of short- and long-term follow-up data, including recurrences and survival.

Main Results:

• Median tumor diameter was 10 cm; 80% were soft tissue, bone, or cartilage sarcomas.
• Reconstruction utilized sandwich technique (mesh/methyl methacrylate/mesh) or e-PTFE mesh.
• Local recurrences (26%) were linked to larger tumors, malignant fibrous histiocytoma, and incomplete resection.

Conclusions:

• Malignant chest wall tumors predominantly comprise mesenchymal neoplasms.
• Radical resection of low-grade tumors offers long-term survival.
• Large tumor size and specific histologies like malignant fibrous histiocytoma are associated with higher recurrence rates.
