The aim of this study was to evaluate the efficacy and safety of apatinib for patients with unresectable ICC.Patients and Methods: A total of 10 patients with unresectable ICC were enrolled for this single-center observational study between March 2, 2016, and August 27, 2019. Subjects received 500 mg apatinib on a daily basis. Tumor response was assessed by 1.1 response evaluation criteria in solid tumors. The progression-free survival (PFS) and overall survival (OS) were calculated using the Kaplan–Meier method. The drug-related adverse effects were also monitored.Results: Based on the follow-up computed tomography and magnetic resonance imaging after treatment, 4 (40.0%), 4 (40.0%), and 2 (20.0%) patients achieved a partial response, stable disease, and progression of the disease, respectively. The response rate and disease control rate were 40.0% and 80.0%, respectively. The median PFS was 4.5 months (95% confidence interval: 3.157∼ 5.843 months); the median OS was 6.5 months (95% confidence interval: 4.744∼ 8.256 months). Furthermore, 3-, 6-, and 9-month OS rates were 77.5%, 61.7%, and 15.0%, respectively. The most common hematologic grade 3 adverse event was neutropenia (10%); the most common nonhematologic grade 3 adverse events were hypertension (20.0%) and hand-foot syndromes (20.0%). No treatment-related grade 4 or 5 adverse events were recorded.Conclusion: Apatinib revealed to have antitumour activity in unresectable ICC patients, with manageable toxicities, and thus might be used as a new treatment option for patients with unresectable ICC.Keywords: apatinib, intrahepatic cholangiocarcinoma, targeted therapy, efficacy, safety
