Furthermore, the drug repurposing approach is even more applicable for STS with oncogenic mutations: gastrointestinal stromal tumors (GIST) with activating mutations in c-KIT, PDGFA and BRAF, myxoid round cell liposarcoma with activating mutation in PI3K/Akt signaling component PI3CA ([24] and Table 2). Here, PDGFA is linked to gastrointestinal stromal tumor.
