Abstract:	Anaplastic thyroid carcinoma (ATC) is rare but highly aggressive. We investigated the association of selected driver mutations, includingBRAF,RAS,PIK3CA,TERTpromoter,TP53,POLE, and mismatch repair deficiency (MMR-D) with the clinicopathological features of ATC to identify prognostic and predictive biomarkers. Thirty-nine retrospective cases from pathology archives were enrolled for clinicopathology analysis and immunohistochemistry, and 27 cases had sufficient specimens for further molecular testing using targeted next-generation sequencing and mass spectrometry.BRAF(V600E)andRASmutations were identified in 25.9% and 40.7% of ATC, respectively.BRAF(V600E)mutation was significantly associated with coexisting papillary thyroid carcinoma (p= 0.009) andRASmutations with female gender (p= 0.012). In univariant analysis, the non-BRAF/RAStumors were significantly associated with the presence of a sarcomatoid pattern (p= 0.045).PIK3CA,TERTpromoter, andTP53mutations were identified in 14.8%, 81.5%, and 70.4% of cases, respectively. No MMR-D orPOLEmutations were detected. In survival analyses,RASandPIK3CAmutations were significantly associated with inferior outcomes (p= 0.03 andp= 0.006, respectively). In conclusion, driver mutations in ATC are associated with distinct clinicopathological features.RASandPIK3CAmutations were negative predictors for patient survival. Emerging therapeutic agents targeting BRAF, RAS, and PI3 kinase may benefit a substantial proportion of ATC patients.
