Thyroid Carcinoma in Cats

Hibbert, A., T. Gruffydd-Jones, et al. (2009). "Feline thyroid carcinoma: diagnosis and response to high-dose radioactive iodine treatment." Journal of Feline Medicine & Surgery 11(2): 116-124.

Thyroid carcinoma is considered to be the cause of hyperthyroidism in 1 to 3% of hyperthyroid cats. Eight cats were included in the study based on pre-mortem histopathologic diagnosis of thyroid carcinoma, scintigraphic evaluation, and sole treatment with high-dose radioiodine. Scintigraphic findings were variable and could not distinguish whether the thyroid tissue was malignant. In all cases, histopathology confirmed malignancy, and the authors recommend histopathology should be done in every case of thyroid surgery. Successful treatment of carcinomas with radioiodine requires ablative doses three- to 10-fold higher than those used for thyroid adenoma. High-dose radioiodine was well tolerated in this group of cats and none of the cats developed clinical hypothyroidism after treatment. The study indicated that the prognosis for cats with thyroid carcinoma and treated with high-dose radioiodine is good, and extended survival times are common. [VT]
