What treatment options are available for a metastatic brain tumor?

The three main options available for metastatic brain tumors are surgical treatment, radiotherapy, and stereotactic surgery.

There are three options for the treatment of metastatic brain tumors:

  • Surgical treatment: Removal of the tumor is usually advised in patients with single brain metastasis and limited spread of cancer in other body parts. An advantage of surgical removal of metastasis is the good demarcation between the tumor and neighboring normal brain tissues, thus the amount of manipulation required in tumor resection is minimized. In addition, the metastatic tumors lie superficially and are close to the brain surface. Computer-assisted surgeries using a frame-less stereotactic system or a robotic microscope may be employed in brain tumor resection.
  • Radiotherapy to the brain is another treatment option for patients with metastatic brain tumors. It is given daily on an outpatient basis for 2-3 weeks. Patients who have undergone surgical removal of a single metastasis are also given radiotherapy as there will always be few cells remaining even after tumor removal.
  • Stereotactic radiosurgery is a new, more advanced type of focused radiation employed in the treatment of metastatic brain tumors.
