Description
Desmoid fibromatosis is a rare, nonmetastatic neoplasm marked by local invasiveness and relentless recurrence. Beta-Catenin deregulation has been commonly identified in sporadic desmoids. CTNNB1 mutations were observed in 117 of 138 (85%) of desmoids. Three discrete mutations in two codons of CTNNB1 exon 3 were identified: T41A (59%), S45F (33%), and S45P (8%). Five-year recurrence-free survival was significantly poorer in S45F-mutated desmoids (23%, P < 0.0001) versus either T41A (57%) or nonmutated tumors (65%). In conclusion, CTNNB1 mutations are highly common in desmoid tumors. Furthermore, patients harboring CTNNB1 (45F) mutations are at particular risk for recurrence and therefore may especially benefit from adjuvant therapeutic approaches.
