Single-institution, multidisciplinary experience with surgical resection of primary chest wall sarcomas.

Introduction: Primary chest wall sarcomas are rare mesenchymal tumors and their mainstay of therapy is wide surgical resection. We report our single-institution, multidisciplinary experience with full-thickness resection for primary chest wall sarcomas.

Methods: A retrospective review of our prospectively maintained databases revealed that 51 patients were referred for primary chest wall sarcomas from 1990 to 2009.

Results: All patients required resections that included rib and/or sternum. Twenty-nine patients (57%) had extended resections beyond the chest wall. Forty-two patients (82%) required prosthetic reconstruction and 17 patients (33%) had muscle flap coverage. Overall, 51% (26/51) of patients received neoadjuvant therapy. Seventy-three percent (11/15) of high-grade soft tissue sarcomas, 77% (10/13) of high-risk bony sarcomas, and 67% (4/6) of desmoid tumors were treated with induction therapy. Negative margins were obtained in 46 patients (90%). There were no perioperative mortalities. Eight patients (16%) experienced complications. Local recurrence and metastasis was detected in 14 and 23%. Five-year overall and disease-free survivals were 66% and 47%, respectively. Favorable prognostic variables for survival included age ≤50 years, tumor volume ≤200 cm, desmoid tumor, bony tumor, chondrosarcoma, and low-grade soft tissue sarcoma.

Conclusions: We report our multidisciplinary experience with primary chest wall sarcomas that included induction therapy in the majority of high-risk soft tissue and bony sarcomas and desmoid tumors. Despite aggressive preoperative treatments, acceptable surgical results with low morbidity and mortality can be achieved. Neoadjuvant systemic therapy may reduce local and distant recurrence and improve overall survival.
