Los depósitos metastásicos en el cerebro se presentan entre el 25 y 35% de los pacientes con cáncer sistémico. El tumor metastásico cerebral es la neoplasia intracraneal más común en adultos y su presentación es 10 veces mas frecuente que los tumores primarios del sistema nervioso central. Se han desarrollado avances significativos en el diagnóstico y tratamiento de las metástasis cerebres, y el nihilismo terapéutico del pasado, ha sido relativamente superado para muchos pacientes. Palabras Claves: SNC, metástasis única, metástasis múltiples, radioterapia, cirugía, quimioterapia.

Abstract: | |
Metastases to the brain occur in 25 to 35% of patients with systemic cancer. Cerebral metastatic is the most common intracranial tumor in adults and occur up to 10 times more frequently than primary tumors in the central nervous system. Significant advances have occured in the diagnosis and treatment of metastases to the brain, and the therapeutic nihilism of the past is now no longer warranted for most patients. With the currently available treatments, most patients do not die of their brain metastases and usually experience effective palliation of neurologic symptoms and meaning full extension o life. As a trial to limit the cerebral metastatic disease, many and diverse therapy options have been developed such as: chemotherapy, surgery plus whole-brain radiotherapy, only radiation therapy, therapy with neutron, intersticial brachytherapy, and stereotactic radiosurgery. In selected cases, surgery plus whole-brain radiotherapy is the conventional treatment for single metastases. However, recurrence usually limits the quality of life and greatly decrease the patients time life, and the therapy options are scarce. This piece of writing also includes a review of the available therapy forms to manage this kind of lesions.
