BARROS, Gisela et al. Malignant bone tumors in Pediatrics. Five year experience in a pediatric referral center. rev.fac.med. [online]. 2016, vol.64, n.3, pp.403-407. ISSN 0120-0011. https://doi.org/10.15446/revfacmed.v64n3.50475.
Background:
Osteosarcoma (OS) and Ewing's Sarcoma (ES) are the two most common malignant bone tumors in children. A retrospective review of the records of children diagnosed in a pediatric hospital over a five year period (2008-2013) was performed.
Objective:
To present the experiences acquired during the treatment of these types of tumors and to compare the results obtained with those reported in the literature.
Methodology:
The database of the Oncology and Pathology Service of Fundación Hospital de la Misericordia (HOMI) was reviewed to identify patients with primary bone tumors referred for histopathology analysis.
Results:
22 patients were diagnosed with OS, with a mean age of 11.9 years. 96% of cases were located in the lower extremities. All patients received neoadjuvant chemotherapy and 86% underwent surgical treatment; 13% survived. 15 patients were diagnosed with ES, with a mean age of 12.4 years. 67% of cases were located in flat bones, 53% of patients had metastasis when diagnosed, and all received neoadjuvant chemotherapy. 40% of patients received surgical intervention and 20% received radiotherapy. Survival at the completion of the reseearch was 33%.
Conclusions:
Cure and survival rates are lower than those reported in the literature despite efforts to improve treatments.
