Gatekeeper Mutations and Intratumoral Heterogeneity inFGFR2-Translocated Cholangiocarcinoma.
MetadataShow full item record
<b/>FGFR2genetic translocations are frequent in cholangiocarcinoma, yet despite initial sensitivity to FGFR inhibitors in clinic, patients quickly become resistant to targeted therapies. The work published by Goyal and colleagues demonstrates that acquisition of gatekeeper mutations inFGFR2and intratumoral heterogeneity drive resistance in patients withFGFR2-translocated intrahepatic cholangiocarcinoma, which will have important implications for management of the disease in clinic.Cancer Discov; 7(3); 248-9. ©2017 AACR.See related article by Goyal et al., p. 252.
