Background: this study was designed to establish a biomarker risk model for predicting bone metastasis in stage iii non-small cell lung cancer (nsclc). methods: the model consists of 105 cases of stage iii nsclc,who were treated and followed up. the patients were divided into bone metastasis group (n = 45) and non-bone metastasis group (other visceral metastasis and those without recurrence) (n = 60). tissue microarrays were constructed for immunohistochemical study of 10 molecular markers associated with bone metastasis,based on which a model was established via logistic regression analysis for predicting the risk of bone metastases. the model was prospectively validated in another 40 patients with stage iii nsclc. results: the molecular model for predicting bone metastasis was logit (p) = ? 2.538 + 2.808 cxcr4 +1.629 bsp +0.846 opn-2.939 bmp4. roc test showed that when p ≥ 0.408,the sensitivity was up to 71% and specificity of 70%. model validation in the 40 cases in clinical trial (nct 01124253) demonstrated that the prediction sensitivity of the model was 85.7%,specificity 66.7%,kappa: 0.618,with a high degree of consistency. conclusion: the molecular model combining cxcr4,bsp,opn and bmp4 could help predict the risk of bone metastasis in stage iiia and iiib resected nsclc. © 2012 zhou et al.
