KIT V560_L576del KIT V654A | gastrointestinal stromal tumor | sensitive | Sunitinib | Preclinical | Actionable | In a preclinical study, a patient derived GIST cell line co-harboring KIT V560_L576del and KIT V654A demonstrated sensitivity to treatment with Sutent (sunitinib) (PMID: 25239608). | 25239608 | |
KIT V560_L576del KIT V654A | gastrointestinal stromal tumor | sensitive | Olverembatinib | Preclinical - Cell line xenograft | Actionable | In a preclinical study, Olverembatinib (HQP1351) treatment inhibited Kit downstream signalling, resulted in cell cycle arrest and apoptosis in a Gleevec (imatinib)-resistant gastrointestinal stromal tumor (GIST) cell line harboring KIT V560_L576del and V654A in culture, and inhibited tumor growth in a cell line xenograft model (PMID: 31673329). | 31673329 | |
KIT V560_L576del KIT V654A | gastrointestinal stromal tumor | sensitive | Regorafenib | Preclinical - Pdx | Actionable | In a preclinical study, Stivarga (regorafenib) inhibited tumor growth in a patient-derived xenograft (PDX) model of gastrointestinal stromal tumor harboring KIT V560_L576del and V654A with overexpression of GPR20 (IHC score 3+) (PMID: 33579785). | 33579785 | |
KIT V560_L576del KIT V654A | gastrointestinal stromal tumor | sensitive | Sunitinib | Preclinical - Pdx | Actionable | In a preclinical study, Sutent (sunitinib) inhibited tumor growth in a patient-derived xenograft (PDX) model of gastrointestinal stromal tumor harboring KIT V560_L576del and V654A with overexpression of GPR20 (IHC score 3+) (PMID: 33579785). | 33579785 | |
KIT V560_L576del KIT V654A | gastrointestinal stromal tumor | resistant | Imatinib | Preclinical - Pdx | Actionable | In a preclinical study, a patient-derived xenograft (PDX) model of gastrointestinal stromal tumor harboring KIT V560_L576del and V654A with overexpression of GPR20 (IHC score 3+) demonstrated resistance to treatment with Gleevec (imatinib) (PMID: 33579785). | 33579785 |
