Osteosarcoma is the most frequent primary high grade bone tumor, usually occurring in adolescents and children. The aim of the present study was to investigate parameters of bone turnover as urinary excretion of pyridinoline (Pyr), and deoxypyridinoline (D-Pyr), serum osteocalcin (OC), and total alkaline phosphatase (AP) in patients with osteosarcoma. Thirty-five patients aged 7-22 (median age 14) with primary high-grade osteosarcoma of the extremity entered the study. A control population of age- and sex-matched healthy individuals was studied. Urinary excretion of Pyr, D-Pyr was measured on fasting urine specimens, corrected for creatine excretion (Ucr), and expressed as pM/microM UCr. At the same time as urine collection, blood samples were taken for measurement of AP and OC. In patients with osteosarcoma the urinary excretion of D-Pyr (74.5 +/- 41) was significantly higher (P = 0.005) than in controls (38.2 +/- 22.5). The serum level of OC was significantly lower (P < 0.001) in patients with osteosarcoma than in controls. Moreover, significantly (P = 0.03) higher excretion of D-Pyr (85.3 +/- 43) was found in patients who relapsed after surgical removal of the tumor and chemotherapeutic treatment compared with those (58.1 +/- 22) who remained continuously free of disease. The present study showed significant abnormalities of urinary excretion of pyridinium crosslinks and serum OC level in patients with osteosarcoma. The relation between urinary excretion of D-Pyr and biological tumor aggressiveness observed in the present study requires further investigation.
