In March 2011, investigators from Australia and several other countries published the results of the DECRA [5] trial in The New England Journal of Medicine.This was a randomized trial comparing decompressive craniectomy to best medical therapy run between 2002 and 2010 to assess the optimal management of patients with medically refractory ICP following diffuse non-penetrating head injury.

If the tumor continues to grow and push on the optic nerve, all vision will be lost in that eye as the nerve atrophies. Proptosis , or anterior displacement of the eye, and palpebral swelling may also occur when the tumor impinges on the cavernous sinus by blocking venous return and leading to congestion.

An average GBM tumor contains 10 11 cells, which is on average reduced to 10 9 cells after surgery (a reduction of 99%). Benefits of surgery include resection for a pathological diagnosis, alleviation of symptoms related to mass effect ...
Especially in the case of larger tumors, there may be a tradeoff between tumor removal and preservation of nerve functionality. There are different defined degrees of surgical excision, termed 'subtotal resection', 'radical subtotal resection', 'near-total resection', and 'total resection' in order or increasing proportion of tumor removed.
