Partial remission of metastatic papillary thyroid carcinoma with sunitinib. Report of a case and review of the literature.
Tyrosine kinase receptors have been implicated in thyroid cancer. Therefore, tyrosine kinase inhibitors may be used for the treatment of advanced metastatic thyroid carcinoma. The aim is to present a case of metastatic papillary thyroid carcinoma responding to the administration of sunitinib, a multi-targeted protein kinase inhibitor. A patient presented with metastatic papillary thyroid carcinoma and hyperthyroidism. After euthyroidism was achieved the patient was treated by the administration of therapeutic radioiodine (131)I, radiotherapy and sunitinib, a multi-targeted tyrosine kinase inhibitor. Thyroglobulin levels decreased from 9,594 to 6,816 ng/ml after 1 month, 6 months later being 2,776 ng/ml. The lesion in the pelvis was 12.5 × 9 cm before treatment decreasing thereafter and the patient improved clinically. The administration of sunitinib resulted in partial disease response in a patient with progressive metastatic papillary thyroid carcinoma. Protein kinase inhibitors may prove useful in the management of advanced metastatic papillary thyroid carcinoma.
