摘要: Background Imatinib mesylate inhibits several tyrosine kinases, including BCR-ABL, the C-KIT receptor, and platelet-derived growth factor receptors α β, all of which are associated with disease. We observed that hypophosphatemia developed in some patients either chronic myelogenous leukemia or gastrointestinal stromal tumors who were receiving imatinib. Methods identified 16 had low serum phosphate levels 8 normal levels, whom performed following biochemical measurements: whole-blood ionized calcium, plasma intact parathyroid hormone, total phosphate, 25-hydroxyvitamin D, 1,25-dihydroxyvitamin magnesium, markers bone formation (bone alkaline phosphatase osteocalcin) resorption (N-telopeptide collagen cross-links); urinalysis; creatinine “spot” urine specimens.
