Over the last decade, a range of different treatments were investigated with very limited success. Surgery is the principal component of standard care.3 The extent of GBM resection depends upon the site and eloquence of the brain area involved. Tumors that resides in sites like eloquent cortex, brain stem or basal ganglia are not amenable to surgical intervention and these patients usually have worse prognosis. The surgical success is limited due to the invasive growth of GBM and the difficulty to resect with an sufficient safety margin.5 Chemo- and radiotherapy have limited effectivity dure to early resistance and accumulation of side effects.
GBM remains incurable due to its heterogeneity and complex pathogenesis. More research efforts will in future help improve treatment options in the fight against the disease.
