Pathophysiology, clinical manifestations and supportive care of metastatic brain cancer.
Brain metastases (BrM) are tumours that originate in tissues outside the central nervous system and spread secondarily to involve mainly the brain. The management of patients with cerebral metastases is complex, costly, and in some instances controversial. Furthermore, even in patients with widespread systemic cancer, the symptoms of the disease are often controllable while the symptoms of the BrM may be disabling. The treatment of BrM is one of the few areas of neuro-oncology where real progress has been made in the last twenty years. Moreover, the costs of managing this disease are rising, as therapies become more intensive and the number of patients with BrM increases. Modern neuroradiological imaging techniques, which are able to discover BrM earlier in the course of systemic cancer, and the greater efficacy of specific treatments, which lengthens survival, have increased the prevalence. The aggressive treatment of BrM may add some benefits to the patient, but its excessive cost leads to the necessity for accurate cost-effectiveness analysis. The latter begins with a complete understanding of the disease: its diagnosis, natural history and results of various modalities of treatment. While the development of BrM usually indicates a poor prognosis for the patient, advances in supportive care have made it possible to reverse most of the neurological symptoms and to give patients a meaningful extension of useful life.
