Status: Trial

Results: chance of VS tumor stability

Aspirin for the chance of Vestibular Schwannoma (VS)/Acoustic Neuroma (AN) - Studies so far reveal best chance is tumor stability, not a reduction. Are the side effects with the possible chance of stability?

The over-the-counter medication (OTC) aspirin, includes both blood thinners and nonsteroidal anti-inflammatory agents which has been found beneficial to Vestibular Schwannoma (VS) tumor control in mouse trials. Common side effects for the use of aspirin of tinnitus, nausea/vomiting, dizziness, hearing loss, and kidney failure are also common effects of VS tumor growth, specifically from vestibular nerve and cochlear nerve damage, as well as brain tumor-induced migraines.

Aspirin use for Vestibular Schwannoma (VS) may be a good option for individuals who have NF2 but have not developed any nerve damage from existing VS yet and are looking to delay issue development before it occurs. Options this simple are the reason for confirmed proof of NF2 diagnosis if another family has NF2, or if other symptoms of NF2 are present.

While aspirin is an over the counter medication, discuss considering it as something to take with your doctor if considering it.

* Many prescriptions and supplements are known to have negative interactions with aspirin.

Possible Side Effects

  • difficulty hearing
  • tinnitus (ringing in the ears)

  • gastrointestinal bleeding
  • kidney problems (watch for change in urine color or amount of urine)
  • persistent or severe nausea/vomiting
  • unexplained tiredness
  • dizziness
  • yellowing eyes/skin

Furthermore, there was no apparent relationship between aspirin dosage, non-aspirin NSAID use, and COX-2 selectivity with VS growth, presenting tumor diameter at presentation, or mean VS growth rate."
