The primary course of action described in medical literature is surgical removal (ressection), a craniotomy(to open the skull) to best access the tumor site, currently minimal invasive techniques are being studied but far from being common practice. The prime re mediating objective of surgery is to remove as many tumor cells as possible, in any case surgery will reduce the tumor size and will attempt to completely remove the neoplasm. In some cases access to the tumor is impossible and impedes surgery.
Many meningiomas, with the exception of some tumors located at the skull base, can be successfully removed surgically. Most can be removed surgically, often using a minimally invasive approach through the nasal cavity and skull base (trans-nasal, trans-sphenoidal approach). Large pituitary adenomascraniotomy (opening of the skull) for their removal. Radiotherapy, including stereotactic approaches, is reserved for the inoperable cases. require a
Although there is no generally accepted therapeutic management for primary brain tumors, a surgical attempt at tumor removal or at least cytoreduction (that is, removal of as much tumor as possible, in order to reduce the number of tumor cells available for proliferation) is considered in most cases.[13] However, due to the infiltrative nature of these lesions, tumor recurrence, even following an apparently complete surgical removal, is not uncommon. Several current research studies aim to improve the surgical removal of brain tumors by labeling tumor cells with a chemical (5-aminolevulinic acid) that causes them to fluoresce.[14] Postoperative radiotherapy and chemotherapy are integral parts of the therapeutic standard for malignant tumors. Radiotherapy may also be administered in cases of "low-grade" gliomas, when a significant tumor burden reduction could not be achieved surgically.
The main treatment option for single metastatic tumors is surgical removal, followed by radiotherapy and/or chemotherapy. Multiple metastatic tumors are generally treated with radiotherapy and chemotherapy. Stereotactic radiosurgery (SRS), such as Gamma Knife, Cyberknife or Novalis Tx, radiosurgery, remains a viable option. However, the prognosis in such cases is determined by the primary tumor, and it is generally poor.
