Background: Globally, prostate cancer is the second most common malignancy in males and fifth leading cancer-related cause of death. To build a reliable predictive system for screening performance, the study looking into the risk factors of BM in prostate cancer patients is warranted. Aim: Using the Surveillance, Epidemiology, and End Results database (SEER) to assess the incidence, and risk factors of morbidity and prognosis for bone metastases in initial metastatic prostate cancer. Methods: A total of 249,331 prostate cancer patients who were diagnosed between 2010 and 2014 in SEER database were obtained to investigate the risk factors for developing bone metastasis, and 9925 of them who registered before 2013 were retrieved (with at least 1 year follow-up) to explore the prognostic factors for bone metastasis. Multivariate logistic and Cox regression were used to identify risk factors and prognostic factors for bone metastases, respectively. Results: Totally, 12,794 patients (5.1%) were diagnosed with bone metastases at the initial diagnosis. Older age, unmarried status, higher tumor stage, lymph node metastasis, metastases at lung brain and liver were the homogeneous risk factors for the morbidity and prognosis of bone metastasis in prostate cancer. Race and histologic differentiation grade were the heterogeneities associated factors. Black race was positively associated with bone metastasis morbidity; however, it has no significant effect on the prognosis. Poor differentiated grade may be the risk factors for developing bone metastasis; however, grade II was negatively associated with prognosis of bone metastasis. Conclusion: The survival of prostate cancer was poor with the bone metastasis approximate 5%. The prostate cancer has homogeneous and heterogeneities risk factors for incidence and prognosis of bone metastasis, which may provide potential guideline for the screening and preventive treatment of the bone metastasis of prostate cancer.
