Epidemiology of central nervous system metastases.

摘要: Brain metastases are overwhelmingly the most common type of brain tumor, out numbering primary tumors in incidence by more than four-to-one. They associated with poor prognosis both from a length-of-life as well quality-of-life standpoint. Once metastasis is detected, without treatment, patients die within months, either widespread systemic disease, or due to itself. The complications also devastating. Patients can suffer seizures, weakness paralysis, language and communication deficits, cognitive decline. These negatively impact on quality life through effects functional independence, impairment capacity participate activities relationships, distortion individual personality identity. At same time, there great financial burdens care treatment metastases. Early detection cancer critical for limiting these complications, minimizing improving outlook regarding survival life. Understanding epidemiology lead development new strategies early identification successful patients.
