Survival after surgical resection for high-grade chest wall sarcomas

Indications for chest wall resection of metastatic or locally recurrent sarcoma and for subsequent bony reconstruction are controversial. Twenty-eight patients had chest wall resection for high-grade primary, metastatic, or recurrent sarcoma. In all patients, resection with selective reconstruction of the bony thorax was performed without operative mortality. Since 1980, only patients with four or more ribs resected have had selective bony reconstruction. Follow-up ranged from 8 to 132 months (median follow-up, 42 months). All deaths were related to sarcoma recurrence. The overall actuarial survival rate was 85% at 1 year, 65% at 3 years, and 59% at more than 5 years. The overall actuarial proportion without disease recurrence was 64% at 1 year, 52% at 3 years, and 40% at more than 5 years. There was no significant difference in overall or disease-free survival for patients with primary, metastatic, or recurrent tumors. The most important prognostic factors were positive margins and concomitant pulmonary resection for synchronous lung metastases. These data support aggressive resection to obtain pathologically tumor-free margins for chest wall sarcomas, whether primary, metastatic, or recurrent. Reconstruction can be individualized based on the extent of resection.
