Case series reveals effective local response in metastatic thyroid carcinoma treatment, indicating future guidelines need to include radioembolization.
Liver metastases from well-differentiated thyroid carcinomas are rare. We report 3 patients, 1 with follicular and 2 with oncocytic thyroid cancers, treated for liver metastases with yttrium-90 radioembolization. The 2 patients with oligometastatic disease received ablative radiation doses, while 1 patient with diffuse metastatic liver disease was treated palliatively with 2 sessions of reduced nonablative radiation dose due to a large hepatopulmonary shunt fraction diagnosed at work-up. The 2 cases of oligometastatic disease had a complete local response by imaging criteria, while the third case had a pronounced local partial response, without adverse events. Future guidelines should include radioembolization as a viable option for locoregional therapy of liver metastases of differentiated thyroid cancer not responsive to radioiodine in patients that do not qualify for or refuse hepatic surgery.
