RT Journal Article SR Electronic A1 Boltz, Kathy T1 Targeted and Salvage Therapies Benefit Patients With Thyroid Cancer JF MD Conference Express YR 2015 FD SAGE Publications VO 15 IS 4 SP 25 OP 26 DO 10.1177/1559897715581829 UL http://mdc.sagepub.com/content/15/4/25.abstract AB Sorafenib and lenvatinib can be effective for advanced differentiated thyroid cancer, and vandetanib and cabozantinib can be effective options for advanced medullary thyroid cancer. When first-line tyrosine kinase inhibitors fail for patients, evidence supports salvage therapy for differentiated thyroid cancer but is less compelling for medullary thyroid cancer.
