Outcomes of chest wall resections in pediatric sarcoma patients

Purpose: Chest wall tumors in pediatric patients are rare. This study evaluates outcomes in pediatric patients who have undergone chest wall resections secondary to sarcomas. Methods: A retrospective review was performed for patients <19 years old who underwent chest wall resections for sarcoma 1999-2014 at the University of Texas MD Anderson Cancer Center. Results: Of 44 patients, Ewing's sarcoma (n=18) and osteosarcoma (n=16) were most common. Other sarcomas included synovial sarcoma, chondrosarcoma, and rhabdomyosarcoma. Gore-Tex (R) or a Marlexr (TM) mesh and methyl methacrylate sandwich was used in 22 patients, and 9 children did not require reconstruction. Twenty-four (54.5%) patients had normal activity, 3 (6.8%) had occasional discomfort, 2 (4.5%) had pain impairing function, 7 (15.9%) required medication or physical therapy for impairment, and S (182%) needed additional surgery. live children (11A%) developed scoliosis, and all of these patients had posterior rib tumors. Median overall survival for the entire cohort was 41.9 +/- 11.82 months. Histology (p=0.003), location of tumor on the ribs (p=0.007), and surgical margins (p=0.011) were significantly associated with overall survival. Tumors on the middle and posterior (p=0.003) portions of the ribs had a lower chance of death. Conclusion: Scoliosis is more common in posterior rib resections. Histology, location of the tumor, and surgical margins impact survival, but, type of reconstruction does not. (C) 2017 Published by Elsevier Inc.
