    Title:

    Selumetinib-Enhanced Radioiodine Uptake in Advanced Thyroid Cancer

    Excerpt:
    Nine patients had a BRAF V600E mutation, 5 had an NRAS mutation at codon 61 (Q→R or K), 3 had RET/PTC rearrangements....All five patients with NRAS-mutant tumors had increased iodine uptake in response to selumetinib; four had confirmed partial responses and one had stable disease after radioiodine administration
