We computed the prevalence and prognosis of bone metastases in each cancer and compared their survival in different stages. The Kaplan-Meier method and Cox logistic regression were used to analyse survival and quantify the effect of bone metastases.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>This study included 89\u2009782 patients with bone metastases at diagnosis. Lung cancer had the highest prevalence (18.05%), followed by liver cancer (6.63%), nasopharyngeal carcinoma (6.33%) and renal cancer (5.45%). Breast cancer (32.1%), prostate cancer (25.9%), thyroid cancer (46.9%) and nasopharyngeal carcinoma (24.8%) with only bone metastases had a 5-year survival rate of over 20%. Compared with patients at the stage previous to metastasis, bone metastases significantly increased the risk of mortality and decreased survival, especially for those with prostate cancer (adjusted HR: 18.24). Other concomitant extraosseous metastases worsened patient survival. Bone was the most common site of metastasis for prostate cancer, while for colorectal cancer, multiorgan metastases were predominant.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>This study provides the prevalence and prognosis of bone metastases at the initial diagnosis of common solid cancers.
