Bone metastases from prostate cancer, especially in the spine, can lead to pathological fractures, which can cause paraplegia and even fecal and urinary incontinence. This is because prostate cancer is most likely to develop bone metastasis, especially spinal bone metastasis. Once spinal metastasis occurs, the spinal bone is the weight-bearing bone, and fracture of the weight-bearing bone causes occupying lesions in the spinal canal, which can lead to paralysis, and this can seriously affect the life expectancy of patients with bone metastasis from prostate cancer. The prognosis of prostate cancer is good, but bone metastasis, especially spinal bone metastasis, needs to be treated actively by radiotherapy, local internal fixation or nuclear implantation. Of course, systemic treatment for the prostate, such as endocrine therapy, chemotherapy or radiotherapy, is a must.
