摘要: Angiosarcoma is an aggressive malignancy that arises spontaneously or secondarily to ionizing radiation chronic lymphoedema. Previous work has identified aberrant angiogenesis, including occasional somatic mutations in angiogenesis signaling genes, as a key driver of angiosarcoma. Here we employed whole-genome, whole-exome and targeted sequencing study the changes underpinning primary secondary We recurrent two PTPRB PLCG1, which are intimately linked angiogenesis. The endothelial phosphatase PTPRB, negative regulator vascular growth factor tyrosine kinases, harbored predominantly truncating 10 39 tumors (26%). signal transducer encoded recurrent, likely activating p.Arg707Gln missense variant 3 34 cases (9%). Overall, 15 (38%) at least one mutation genes. Our findings inform reinforce current therapeutic efforts target
