Surgery is the mainstay of treatment for glioblastoma.
- An average glioblastoma tumor contains 1011 cells, which is on average reduced to 109 cells after surgery (a reduction of 99%). It is used to take a section for a pathological diagnosis, to remove some of the symptoms of a large mass pressing against the brain, to remove disease before secondary resistance to radiotherapy and chemotherapy, and to prolong survival.
The greater the extent of tumor removal, the better. Removal of 98% or more of the tumor has been associated with a significantly longer healthier time than if less than 98% of the tumor is removed. The chances of near-complete initial removal of the tumor can be greatly increased if the surgery is guided by a fluorescent dye known as 5-aminolevulinic acid. Glioblastoma tumor cells are widely infiltrative through the brain at diagnosis, and so despite a "total resection" of all obvious tumor, most people with glioblastoma later develop recurrent tumors either near the original site or at more distant "satellite lesions" within the brain. Other modalities, including radiation, are used after surgery in an effort to suppress and slow recurrent disease.
