Name of journal: Journal of the Endocrine SocietyAbstract: Background and Objective: The brain is an unusual site for distant metastases of differentiated thyroid carcinoma (DTC). The aim of this study was to document the prevalence of brain metastases from DTC at our institutions and to analyze the current therapies and the outcomes of these patients.Conclusion: The prevalence of brain metastases of DTC in our institutions was 0.3% over 15 years. The median survival time after diagnosis of brain metastases was 19 months. In our study population, the use of TKI improved the survival rates.Methods: We performed a retrospective chart review of patients with DTC and secondary neoplasia of the brain.Results: From 2002 to 2016, 9514 cases of thyroid cancer were evaluated across our institutions and 24 patients met our inclusion criteria, corresponding to a prevalence of 0.3% of patients with DTC. Fourteen (58.3%) were female and 10 (41.7%) were male. Fifteen patients had papillary thyroid cancer (PTC) (62.5%). Brain metastases were diagnosed 0 to 37 years (mean +/- SD, 10.6 +/- 10.4 years) after the initial diagnosis of thyroid cancer. Patients undergoing surgery had a median survival time longer than those that did not undergo surgery (27.3 months vs 6.8 months; P = 0.15). Patients who underwent stereotactic radiosurgery (SRS) had a median survival time longer than those that did not receive SRS (52.5 months vs 6.7 months; P = 0.11). Twelve patients (50%) were treated with tyrosine kinase inhibitors (TKIs), and they had a better survival than those who have not used a TKI (median survival time, 27.2 months vs 4.7 months; P < 0.05).All authors: Aulisi EF, Burman KD, Deeb H, Gomes-Lima CJ, Hritani R, Jonklaas J, Mete M, Punukollu S, Rao SN, Van Nostrand D, Wartofsky L, Wu D, Zeymo AFiscal year: FY2019Digital Object Identifier: ORCID: Date added to catalog: 2019-03-14
