Resumen

Todas las modalidades terapéuticas de que disponemos en la actualidad sobre los astrocitomas anaplásicos y glioblastoma multiforme son paliativas. La finalidad de dichos tratamientos es la de conseguir los más largos períodos de supervivencia con buena calidad de vida, pero incluso la combinación de los distintos tratamientos consigue resultados de supervivencia desalentadores.

En la actualidad, gracias al auge de los estudios citogenéticos y de biología molecular, nuevas perspectivas en la actividad investigadora nos abren futuras estrategias de tratamiento. Estas técnicas nos muestran cómo la iniciación y progresión de un tumor neuroepitelial es el resultado de la expresión inadecuada y exagerada de proto-oncogenes, a partir de los cuales se ponen en marcha sistemas con actividad biológica que conducen a la desdiferenciación y proliferación celular.

Por otro lado, las técnicas inmunohistológicas empleando anticuerpos monoclonales de alta especificidad, que nos valoran la cinética tumoral, nos permiten evaluar el pronóstico de los pacientes y la eficacia de las diversas opciones terapéuticas.

La presentación de los mecanismos implicados en la fisiopatología, diagnóstico y técnicas de estudio histológicas de los tumores anaplásicos neuroepiteliales del adulto y cómo dichos mecanismos convergen a nivel molecular repercutiendo en el conocimiento de la biología del ciclo celular, son el objetivo del presente artículo.

Abstract

All currently available therapies on anaplastic astrocytomas and glioblastoma multiforme are palliative. The goal of treatment is to provide the longest period of good quality life but the setup treatment achieve discouraging results.

Now, by the neurogenetics and the molecular biology of human brain tumors studies new approaches of research activity shows future treatment strategies. So, the initiation and progression of a neuroepithelial tumor is the result of inappropiate expresion of protooncogen, which encoding systems with biological activities that influence cell differentiation and proliferation.

With the production of monoclonal antibodies with high specific binding characteristics, inmunohistology, tumoral cytocinetics studies became the preferable method by which to evaluate the prognosis and treatment options. In this article, the pathogenesis and diagnosis technics are reviewed and we can appreciate Iike in cell cycle, all oncogenic influences must converge.
