Osteosarcoma is the most common primary bone malignancy in childhood and adolescence. Its peak age of onset has suggested a possible contribution to the pathogenesis of the tumor by the endogenous hormonal milieu, which accompanies the adolescent growth spurt. In support of this, recent in vitro and in vivo laboratory investigators suggest that Insulin-like growth factor I (IGF I) may play an important role in the pathobiology of osteosarcoma. Somatostatin (and its longer-acting analogues) directly inhibits the pituitary release of growth hormone, thereby indirectly reducing the level of ci...
