New trends in skeletal reconstruction after resection of chest wall tumors.

Involvement of the chest wall in malignant tumors, either primary or resulting from contiguous or metastatic spread, occurs in less than 5% of thoracic malignancies. From 1963 through 1978, 155 patients had chest wall resection in continuity with the tumor. Eighty-five tumors were carcinomas, and 70 were sarcomas. Since 1973 reconstruction of chest wall defects in 12 patients has included the use of a composite of Marlex mesh and methyl methacrylate. It provides an excellent replacement both physiologically and esthetically. Such a reconstructed chest wall has obviated the need for postoperative respiratory support. The overall mortality was 4.5% (7 out of 155). The 5-year survival in this varied group of patients is 20%. We believe excellent palliation can be achieved even in patients who are not potentially curable.
