转移性骨肿瘤是恶性肿瘤通过血液循环或淋巴系统转移到骨骼所产生的继发性肿瘤。近年来,随着癌症发病率的上升以及癌症诊疗水平提高后病人生存期的延长,转移性骨肿瘤的发病率也呈逐年上升的趋势。尸检证明70%~80%的肿瘤均可发生骨转移。目前转移性骨肿瘤已成为影响癌症病人生存质量、威胁病人生命的主要问题。
Metastatic bone tumors are secondary tumors that metastases from malignant tumors to the bone through the bloodstream or lymphatic system. In recent years, the incidence of metastatic bone tumors has also been increasing year by year with the increase of the incidence of cancer and the prolongation of the survival of patients after cancer diagnosis and treatment. Autopsy proved that 70% to 80% of the tumors can occur in bone metastases. At present, metastatic bone tumors have become the main issues that affect the quality of life of cancer patients and threaten their life.
