Chest-wall resection can be performed with low morbidity and mortality rates and remains the primary treatment for most chest-wall tumors. However, some lesions are best treated with a multimodality approach including preoperative chemotherapy. Therefore, pretreatment tissue diagnosis is essential in planning. The biopsy should be done at the medical center where the definitive treatment will be undertaken, and frequently, a needle biopsy will be sufficient. Osteosarcoma, rhabdomyosarcoma, Ewing's sarcoma, and other small-cell sarcomas are sensitive to chemotherapy, which should be given preoperatively, continued postoperatively, and modified according to the tumor response. Chondrosarcomas and most adult soft-tissue sarcomas are well controlled by primary excision and selective use of adjuvant irradiation. Better systemic and local therapy is needed for the recurrent soft-tissue sarcomas and the aggressive unclassified sarcomas. Chest-wall resection continues to play a primary role in the management of locally and regionally recurrent breast cancer but is best combined with systemic chemotherapy. Chest-wall resection can provide a long disease-free survival in patients with isolated metastases from sarcomas or carcinomas. In addition, significant palliation can be afforded patients with symptomatic chest-wall metastases and a shortened life expectancy.

Twenty-one patients underwent sternal resection and reconstruction. Surgical indications included sternal infection in 9 patients, recurrent breast cancer in 6, metastatic carcinoma from an unknown primary in 2, pectus excavatum in 2, and osteogenic sarcoma and eosinophilic granuloma in 1 each. Management included partial sternectomy in 10 patients (group 1) and complete sternectomy in 11 (group 2). Chest wall reconstruction was by various flaps and mesh repairs. Blood transfusions averaged 2 units in group 1 versus 5.5 units in group 2 (p = 0.02). Average number of days until extubation was 2.6 in group 1 versus 7.3 in group 2 (p = 0.04). Average number of intensive care unit days was 4.4 for group 1 versus 9.4 for group 2 (p = 0.03). The number of days until discharge was 14 days for group 1 versus 20 days for group 2. Complications occurred in 40% of group 1 and 82% of group 2 patients. Overall mortality was 9.5%. Sternal resection and reconstruction, particularly complete sternal resections, are a major undertaking with substantial morbidity. Using a multidisciplinary approach (cardiothoracic, plastic and reconstructive, critical care medicine, and infectious disease) and aggressive pulmonary support, acceptable cosmetic and functional results are possible.
