| Resumen en inglés | Cancer patients with spinal metastases are a diagnostic and treatment challenge for the clinician. This challenge must be addressed through a multidisciplinary, multimodal, and individualized management. The presence of tumor cells in bone metastases results in homeostatic disruption between bone formation and remodeling. Bone destruction is a late event in the formation of lytic bone metastasis, starting when tumor cells proliferate; this in turn activates osteoclasts, seen as trabecular destruction in imaging studies. There may be excessive bone destruction and increased bone formation, which produce blastic lesions. Bone scintigraphy is currently the most widely used diagnostic method and is considered as the reference test for the diagnosis of spinal bone metastasis. However, we believe that in the near future positron emission tomography associated to computed tomography with 18F-NaF, or magnetic resonance using diffusion-weighted whole-body imaging with background body signal suppression, will replace bone scintigraphy due to their improved diagnostic accuracy. These new diagnostic tools will help prevent bone metastasis complications such as: intractable pain; spinal cord or cauda equina compression; hypercalcemia; pathological fractures; and spinal instability. With regards to the treatment, it can be uni- or multimodal, depending on the type and number of bone metastases. Among the types of treatment available for bone metastasis are chemotherapy, radiotherapy, and invasive procedures. The prognosis of patient survival depends on the histopathology of the primary tumor, the presence of bone metastasis, and the presence of neurological deficits |
