RESUMO
Objective:This study was aimed to investigate the value of osteoclast differentiation factor (ODF) and osteoclastogen-esis inhibitory factor (OCIF) detection for clinical diagnosis and assessment of patient condition in bone metastasis of lung cancer. Methods:Data from 186 lung cancer patients who were preliminary diagnosed between July 2009 and April 2012 were analyzed. Cas-es were divided into the bone metastasis group with 82 cases (group A) and the non-bone metastasis group with 104 cases (group B). Concentrations of serum ODF and OCIF in each group were detected by ELISA. Results: ODF and OCIF values of group A were (32.22±6.22) ng/L and (41.23±8.13) ng/L, respectively, which were significantly higher than the corresponding values in group B [(8.35 ±5.42) ng/L and (10.15±4.42) ng/L]. The differences between the two groups were statistically significant (P0.05). Conclusion:The serum ODF and OCIF concentrations significantly increase when bone metastasis oc-curs in lung cancer patients. Hence, these variables are useful as indices for monitoring bone metastases and evaluating patient condi-tion. An extensive application prospect is proposed.
