Background: Gemcitabine plus cisplatin has been established as a standard chemotherapy regimen for advanced biliary tract cancers (BTCs) based on the phase III UK ABC-02 study, which included all types of biliary cancers. There is very limited data regarding the effectiveness of known chemotherapeutic regimens especially in IHCC.
Methods: Records of 63 patients diagnosis of IHCC who received Gemcitabine and Carboplatin (G-C Regimen) chemotherapy as a first line were retrospectively reviewed.
Aim: The aim of this study is to determine the incidence of T790M mutations after progression on epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKI) and median duration on TKI before progression on TKI.
Methods: Records of Rajiv Gandhi Cancer Institute and Research Centre, of patients who were diagnosed with metastatic adenocarcinoma of the lung and progressed on oral EGFR TKIs and underwent T790M mutation analysis in the last 6 months were retrospectively reviewed. The incidence of T790M positivity, sites of progression, and median duration of TKI treatment before progression was calculated.
