Abstract
Introduction: Anaplastic thyroid cancer (ATC) is a highly aggressive thyroid cancer. Those ATC with genomic alterations (GAs) in TSC2, ALK, and BRAF may respond to targeted therapies. Methods: Comprehensive genomic profiling on 90 ATC specimens identified base substitutions, short insertions and deletions, amplifications, copy number alterations, and genomic rearrangements in up to 315 cancer-related genes and 28 genes commonly rearranged in cancer. Results: Median patient age was 65 (range, 33-86) years, 50 patients were male. There was a mean of 4.2 GA per case, range 1-11. The most common GA were TP53 (66%), BRAF (34%), TERT (32%), CDKN2A (32%), and NRAS (26%). BRAF V600E and NRAS/HRAS/KRAS alteration were mutually exclusive. BRAF, CDKN2A, PIK3CA, and JAK2 were more frequent in patients >70 years of age; while myc, PTEN, and NRAS were more common in those ≤50 years. Conclusion: ATC shows many GA with potential therapeutic significance and suggesting different molecular pathways can lead to ATC.
