Abstract

To investigate the role of insulin-like growth factor-1 (IGF-1), in localized osteosarcoma, serum levels of IGF-1, IGFBP-2, and IGFBP-3 were measured in 224 similarly treated, newly diagnosed patients. We demonstrated that younger patients had lower concentrations of IGF-1 and IGFBP-3 compared to older (P<0.001) along with lower IGFBP-3:IGF-1 and IGFBP-2:IGF-1 ratios (P<0.001). IGFBP-2 did not correlate with age (P=0.16), yet IGFBP-2:IGF-1 ratios were higher in the younger population (P<0.001). These findings show that older patients have higher concentrations of free IGF-1. None of IGF-1, IGFBP-2, nor IGFBP-3 concentrations were associated with event-free nor overall survival.
