There are racial disparities in bone metastasis development and survival among lung cancer patients. Asian and Pacific Islander patients have the highest prevalence of BM and longer survival compared to white and black patients. Individualized screening and treatment based on race could improve overall survival outcomes.
Objective: Race disparities exist in bone metastasis (BM) development and survival in lung cancer (LC) patients. The Surveillance, Epidemiology, and End Results (SEER) database was used to investigate different patterns of BM development and survival in different races. Design: LC patients with BM were identified from the database from 2010 to 2014. Risk factors were investigated by univariable and multivariable logistic regression. Potential factors for prognosis were evaluated by univariable and multivariable Cox regression. Results: Asian and Pacific Islander (API) patients presented the highest prevalence of BM (24.6%), followed by white (20.7%) and black patients (19.9%) (chi 2 = 78.74; p < .001). After adjusting for the demographic and clinical factors, API race was independently associated with a high risk of BM development. The median survival times for the API, white and black LC patients with BM were 16 months (95% CI: 15.2-16.8), 11 months (95% CI: 10.9-11.1) and 10 months (95% CI: 9.7-10.3), respectively, with significant differences (p < .001). Multivariable Cox regression showed that API race was positively associated with greater overall survival compared with white and black patients. Male gender, larger tumor size, lymph node involvement, lower tumor differentiated grade, and the presence of lung, liver and brain metastases were independently associated with a high risk of developing BM and worse survival with LC across all races. Age, income, insurance and histological types had different impacts on BM among different races. Conclusion: Homogeneous and heterogeneous associated factors for BM were revealed among different races. Individualized screening and treatment should be performed race-specifically.
