The use of biochemical markers of bone remodeling in multiple myeloma: a report of the International Myeloma Working Group

Posted · Add Comment

Lytic bone disease is a frequent complication of multiple myeloma (MM). Lytic lesions rarely heal and X-rays are of limited value in monitoring bone destruction during anti-myeloma or anti-resorptive treatment. Biochemical markers of bone resorption (amino- and carboxy-terminal cross-linking telopeptide of type I collagen (NTX and CTX, respectively) or CTX generated by matrix metalloproteinases (ICTP)) and bone formation provide information on bone dynamics and reflect disease activity in bone. These markers have been investigated as tools for evaluating the extent of bone disease, risk of skeletal morbidity and response to anti-resorptive treatment in MM. Urinary NTX, serum CTX and serum ICTP are elevated in myeloma patients with osteolytic lesions and […]
