Currently, complete surgical resection represents the only potentially curative treatment option for cholangiocarcinoma (CCA, including intrahepatic, hilar and distal CCA) and gallbladder carcinoma (GBCA). However,only less than 25% of patients are resectable at diagnosis and, even in this subset of patients, relapse rate is high.~Cisplatin and gemcitabine combination was identified as the standard first-line chemotherapy, yielding a median progression free survival (PFS) and median OS of 8.5 and 11.7 months, respectively. FOLFOX was the standard second-line chemotherapy. But the benefit of FOLFOX was limited.
This is a prospective, Two-arm, comparative, randomized, controlled phase II trial, to explore the efficacy and safety of Regorafenib and HAIC vs. FOLFOX as Second Line Therapy for Advanced Intrahepatic Cholangiocarcinoma.
