Are large, inoperable schwannomas treatable or able to be shrunk with chemotherapy or radiation?

There are typically three methods of treatment for people with a vestibular schwannoma: observation, radiotherapy, and surgery. The best option is often determined based on the size of the tumor; the location of the tumor; the symptoms; and/or the person's age and general health. Each option has unique risks and benefits.[1][2]

Stereotactic radiation therapy (commonly called radiosurgery) is a method of delivering a radiation dose in such a way as to minimize the dose of radiation to surrounding normal tissues (brain) while delivering a very high dose to the tumor. Low dose beams of radiation are aimed from many different directions by a computer to focus on the tumor. However, this form of treatment may not be appropriate for schwannomas in other areas of the body, or for an people with a tumor larger than 2.5 to 3 cm in diameter, as radiosurgery may be ineffective in larger tumors.[3]

Chemotherapy is generally not used for treating schwannomas.[1][2]
