Objective—To compare, for dogs with intracranial
meningiomas, survival times for dogs treated with
surgical resection followed by radiation therapy with
survival times for dogs treated with surgery alone.
Animals—31 dogs with intracranial meningiomas.
Procedure—Medical records of dogs with histologic
confirmation of an intracranial meningioma were
reviewed. For each dog, signalment, clinical signs,
tumor location, treatment protocol, and survival time
were obtained from the medical record and through
follow-up telephone interviews.
Results—Dogs that underwent tumor resection
alone and survived > 1 week after surgery had a
median survival time of 7 months (range, 0.5 to 22
months). Dogs that underwent tumor resection followed
by radiation therapy had a median survival time
of 16.5 months (range, 3 to 58 months).
Conclusions and Clinical Relevance—Results suggest
that in dogs with intracranial meningiomas, use
of radiation therapy as a supplement to tumor resection
can significantly extend life expectancy. (J Am Med Vet Assoc 2002;221:1597–1600)
