RT Journal Article SR Electronic A1 Nichols, Emma Hitt T1 Increased TSH Levels Do Not Affect Safety, Efficacy in Refractory Thyroid Cancer JF MD Conference Express YR 2015 FD SAGE Publications VO 15 IS 4 SP 15 OP 16 DO 10.1177/1559897715581825 UL http://mdc.sagepub.com/content/15/4/15.abstract AB In the SELECT trial, lenvatinib treatment of patients with radioactive iodine 131–refractory differentiated thyroid cancer was associated with increased thyroid-stimulating hormone levels. An exploratory analysis found that worst postbaseline thyroid-stimulating hormone levels were not associated with differences in overall safety, progression-free survival, overall survival, or overall response rate.
