Plain-English summary
An 8-year-old cat diagnosed with thyroid cancer received a single high dose of radioactive iodine treatment. This therapy successfully resolved the cat's hyperthyroidism and led to a significant improvement in its health. Out of eight cases treated, six cats showed complete recovery and lived much longer than expected, with survival times ranging from about six months to over six years. This treatment is considered safe and effective for cats with thyroid cancer, offering a good prognosis for those who respond well.

Abstract
This study reports the scintigraphy, histopathology, sole treatment with high-dose radioactive iodine and outcome of eight cases of feline thyroid carcinoma. Scintigraphic findings were variable and in 7/8 cases scintigraphic features could not reliably distinguish whether the thyroid tissue was malignant. Histopathology revealed typical criteria of malignancy in all cases, with mitotic activity described most frequently (7/8 cases), followed by infiltration of local tissues (4/8 cases). Cellular pleomorphism was infrequently observed. Single high-dose (1100MBq I(131)) radioiodine therapy was successful in 6/8 cases, with complete resolution of hyperthyroidism, and was associated with prolonged survival times (181-2381 days). Sole treatment with high-dose radioiodine is a safe and effective treatment for functional thyroid carcinoma. The prognosis for feline thyroid carcinoma successfully treated with radioiodine is good, with extended survival times commonly achieved.
