ALK and thyroid gland papillary carcinoma: The number of targetable variants was highest in the non-CNS solid tumor cohort (21.8%), including ALK variants in neuroblastoma, NTRK fusions in several different tumor types (including papillary thyroid cancer, mammary analogue secretory carcinoma, and myofibroblastic sarcoma), for whom targeted therapy with crizotinib or TRK inhibition (larotrectinib, entrectinib) was either recommended or available in the relapse setting [47–49].
