The mainstay of the treatment of brain tumors is surgery. Other supportive therapies like chemotherapy, radiotherapy etc. helps in disease free survival. No medical management is available to treat brain tumors completely. Some drugs are used to reduce tumor edema (steroids), treat seizures and headache but have no role in treatment of tumor itself.
It is the mainstay of treatment. The aim of surgery to remove mass effect, get tissue for histopathological diagnosis and excision of mass to cure the disease. Surgery aims at total or gross total excision, but in case of inoperable tumors (eloquent areas) near total excision or simple decompression is also done. Surgery causes immediate relief in mass effect. Benign tumors are usually cured by surgery itself but malignant tumors require chemotherapy or radiotherapy as an adjuvant. Recurrence is the rule in case of malignant brain tumors but recurrence free survival depends upon the type and grade of the tumor. Even after recurrence, surgery is the first line of management. Now a day, advances in surgical techniques facilitate more excision with less deficits and morbidity. Tractography, neuronavigation, CUSA, intraoperative MRI, flouroscine microscopy, intraoperative neurophysiological monitoring are few advances in surgical techniques which improve the result of surgery.
