Brain metastasis treatment guidelines: consensus by the Spanish Society of Neurosurgery Tumor Section.

Brain metastases are tumors that arise from a tumor cell originated in another organ reaching the brain through the blood. In the brain this tumor cell is capable of growing and invading neighboring tissues, such as the meninges and bone. In most patients a known tumor is present when the brain lesion is diagnosed, although it is possible that the first diagnose is the brain tumor before there is evidence of cancer elsewhere in the body. For this reason, the neurosurgeon must know the management that has shown the greatest benefit for brain metastasis patients, so treatments can be streamlined and optimized. Specifically, in this document, the following topics will be developed: selection of the cancer patient candidate for surgical resection and the role of the neurosurgeon in the multidisciplinary team, the importance of immunohistological and molecular diagnosis, surgical techniques, radiotherapy techniques, treatment updates of chemotherapy and immunotherapy and management algorithms in brain metastases. With this consensus manuscript, the tumor group of the Spanish Society of Neurosurgery (GT-SENEC) exposes the most relevant neurosurgical issues and the fundamental aspects to harmonize multidisciplinary treatment, especially with the medical specialties that are treating or will treat these patients.

Consenso sobre guías de tratamiento de los glioblastomas elaborado por el Grupo de Trabajo de Neurooncología (GTNO) de la SENEC / Glioblastoma treatment guidelines: Consensus by the Spanish Society of Neurosurgery Tumor Section

INTRODUCCIÓN: El tratamiento de los glioblastomas (GMB) comienza en la mayor parte de los pacientes con una cirugía, ya sea para la extirpación tumoral, ya sea para la obtención de tejido con el que determinar un diagnóstico histológico. Con el fin de obtener el máximo beneficio de estos tratamientos cada paciente debe ser valorado de forma individualizada por un equipo multidisciplinar, constituido por aquellas especialidades involucradas tanto en el diagnóstico como en el tratamiento. MATERIAL Y MÉTODOS: El objetivo de este trabajo es elaborar unas recomendaciones de tratamiento para los pacientes con GBM, para lo cual un experto en cada campo ha descrito lo más relevante de dicha área basado tanto en su experiencia como en la literatura. RESULTADOS: Se han desarrollado los distintos apartados sobre el tratamiento de los GBM y al final de cada apartado se concluye la recomendación del GTNO. CONCLUSIONES: A pesar de que los GBM son tumores agresivos y el pronóstico es malo, los pacientes se pueden beneficiar de tratamientos que mejoren no solo la supervivencia global sino también la calidad de vida. El neurocirujano debe conocer las distintas opciones de tratamientos, sus indicaciones y riesgos para poder participar activamente en la toma de decisiones y ofrecer un tratamiento neuroquirúrgico oportuno a cada situación

INTRODUCTION: Glioblastoma (GBM) treatment starts in most patients with surgery, either resection surgery or biopsy, to reach a histology diagnose. Multidisciplinar team, including specialists in brain tumors diagnose and treatment, must make an individualize assessment to get the maximum benefit of the available treatments. MATERIAL AND METHODS: Experts in each GBM treatment field have briefly described it based in their experience and the reviewed of the literature. RESULTS: Each area has been summarized and the consensus of the brain tumor group has been included at the end. CONCLUSIONS: GBM are aggressive tumors with a dismal prognosis, however accurate treatments can improve overall survival and quality of life. Neurosurgeons must know treatment options, indications and risks to participate actively in the decision making and to offer the best surgical treatment in every case
