    Predictors of radioiodine (RAI)-avidity restoration for NTRK fusion-positive RAI resistant metastatic thyroid cancers. (PubMed, Eur Thyroid J)
    Case Presentation and We report two cases with RAI-resistant lung metastases treated with larotrectinib: 83-year-old male presenting with an ETV6::NTRK3 fusion-positive tumor with the TERT promoter mutation c.-124C>T, and a 31-year-old female presenting with a TPR::NTRK1 fusion-positive tumor (and negative for TERT promoter mutation)...In contrast, the TERT-negative tumor exhibited successful I-131 reuptake with a TDS of -0.060. As observed for RAI-resistance associated with concurrent TERT and BRAF mutations, the co-occurrence of TERT mutations and NTRK fusions may also contribute to re-sensitization failure.
