Abstract:
Objective To explore skeletal‐related events (SREs) clinical factors and analysis prognosis factors on patients with non‐small cell lung cancer(NSCLC) with bone metastases .Methods We collected clinical data of pathology confirmed 383 patients with non‐small cell lung cancer between April 2007 and January 2007 in the third affiliated hospital of the third military medical uni‐versity .It was used to screening for Emission Computed Tomography (ECT ) for bone metastases .And then it was need to con‐firmed for CT ,MRI or PET‐CT or pathology .Statistics in patients between clinical features and the SREs prediction factor with Univariate and Multivariate .And Kaplan‐Meier method analysis of survival in the non‐small cell lung cancer patients with bone me‐tastases .Results Out of 383 patients with bone metastases ,178 patients with SREs .The incidence was 46 .5% .Univariate analysis showed that women ,adenocarcinoma ,never smoking history ,single bone metastases ,bisphosphonate therapy ,targeted therapy in patients with bone metastases are less likely to have SREs ,it was considered statistically significant (P<0 .05) .Multivariate analy‐sis showed multiple bone metastases and no bisphosphonate therapy is independent risk factors for SREs .Median survival time was 14 .5 months in non‐small cell lung cancer patients with bone metastases ,1 year survival rate was 46 .5% ,2 years survival rate was 15 .9% .The survival analysis shows that more bisphosphonate treatment and bisphosphonate with EGFR‐TKI therapy on the prog‐nosis of patients with statistically significance (P<0 .05) .Conclusion It was likely to occur SREs in NSCLC patients with bone metastases .No bisphosphonate and multiple bone metastases are independent risk factors for SREs .Bisphosphonate treatment may prevent or reduce occur SREs for NSCLC patients with bone metastases ,and it may prolong survival ,it speculated that bisphospho‐nate may have resistant NSCLC cell activity .
