ABSTRACT The efficacy and cost/performance benefit of radionuclide bone scintigraphy in monitoring metastatic bone activity remain controversial. Recently developed bone metabolic markers are expected to play an additional role in the diagnosis of bone metastasis. We measured osteoclastic and osteoblastic markers in 267 patients with breast cancer (100 with bone metastasis), 38 patients with prostatic cancer (25 with bone metastasis), 50 patients with lung cancer (12 with bone metastasis) and 33 patients with miscellaneous cancers (13 with bone metastasis) and compared the values in the presence and absence of bone metastasis. Bone metabolic markers, both osteoclastic and osteoblastic, increased significantly in patients with bone metastasis. In breast cancer (bone metastasis is mostly of the mixed type), osteoclastic markers were good in detecting bone metastasis. In prostatic cancer (bone metastasis is mostly osteoblastic), osteoclastic and osteoblastic markers were equally effective in detecting bone metastasis. In lung cancer (bone metastasis is mostly osteolytic), osteoclastic markers were elevated preferentially in bone metastasis. Over all, osteoclastic markers were more sensitive in the diagnosis of bone metastasis, and among osteoclastic markers, serum pyridionoline-cross-linked carboxyterminal telopeptide was the most efficient in both specificity (91.0%) and sensitivity (48.6%) for detecting bone metastasis.
