Abstract:
Gliomas are a common form of intracranial malignancy in adults with poor overall survival and limited treatment strategies. There is significant genetic heterogeneity in this tumor group with a complex network of signaling that leads to rapid infiltrative growth as well as chemo- and radio-resistance. This chapter will delve into the complex processes and molecular alterations that feed into the formation and growth of these primary brain tumors.
Insights
Gliomas are aggressive primary brain tumors in adults with poor survival rates. This chapter explores the complex molecular changes driving glioma growth and resistance to treatment.
