The most common pilocytic astrocytomas in paediatric patients compared to adults, as demonstrated in several reported series, 2—6 corresponds to 2. The first genetic association with the pilocytic astrocytoma was the mutation of gene NF1 and the type I NF-1 neurofibromatosis. Prevalence of central nervous system tumours and When radical surgery is not possible, particularly when the site is profound or in a critical position, radiosurgery plays an essential role in cases of minor residual tumour.

We are confident that this evolution in publication will serve the needs of the international community, as well as to provide our Mexican scientists with greater visibility throughout the global community.


One tool which may help with differential diagnosis of in pilocytic astrocytoma and other tumours is spectroscopy. The accessibility and wide diffusion of on-line publication will provide the opportunity for our scientific colleagues, not only in Latin America, but throughout the world, to share the knowledge and skills of our Mexican surgical community, as well as to astrcoitoma authors from other countries with a forum for participating in our Journal, in order that we may gain knowledge of surgical specialties throughout the world.
