RODRIGUEZ RODRIGUEZ, Eugenio Isidro  y  FERNANDEZ GARCIA, Giselle. Malignant incidence of osseous tumors in children: a five-year study. AMC [online]. 2017, vol.21, n.4, pp. 510-517. ISSN 1025-0255.

Background: malignant bone tumors in children are quite rare. When compared to the rest of the childhood tumors it occupies only 3 to 4%. Despite their low frequency, they are important because of their high mortality, ranging from 80 to 95%, and the serious physical and emotional sequelae that their treatment entails in patients. The most frequent types of malignant bone tumor at that age are Ewing's sarcoma and osteogenic sarcoma. Objective: to determine the most frequent malignant bone tumors with a five-year study of the cases admitted to the Eduardo Agramonte Piña University Pediatric Hospital in Camagüey under the age of 19 years. Methods: an observational, descriptive, longitudinal and retrospective study was carried out through a review of the anatomy pathology file of the Eduardo Agramonte Piña University Pediatric Hospital in Camagüey. We studied all cases with histopathological diagnosis of malignant bone tumor from January 1, 2012 to December 31, 2016, with ages below 19 years. The source of information was the biopsy record book of the Department of Pathology. The data obtained were compiled in a form prepared for them. Statistical analysis was performed using the standard professional package S.P.S.S version 21 2012. The results were presented in tables. Results: Ewing’s sarcoma and osteogenic sarcoma were the most frequent malignant tumors. The most frequent age group of bone tumors was between 10 and 14 years. Conclusions: the results of the study are comparable to those reported in the medical literature where malignant bone tumors, Ewing's sarcoma and osteogenic sarcoma are the most common.
