RESUMO

Fifty cases of nonmetastatic osteosarcoma of the extremities treated between 1986 and 2006 at the Instituto de Ortopedia e Traumatologia do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo were evaluated regarding the expression of VEGF. There were 19 females and 31 males. The mean age was 16 years (528) and the mean followup was 60,6 months (25 167). The variables studied were age, gender, anatomic location, type of surgery, surgical margins, tumor size, post chemotherapy necrosis, local recurrence, pulmonary metastasis and death. Thirtysix patients showed VEGF expression equal or under 30% of the cells (low expression), as the remaining 14 cases had VEGF expression above 30% (high expression). Among the 36 patients with low VEGF expression, nine developed pulmonary metastasis and four died (11,1%). Among the 14 patients with high VEGF expression, six developed pulmonary metastasis and three died (21,4%). There was no statistical significant correlation between the VEGF expression and any of the variables studied
