Patients with unresectable and advanced intrahepatic cholangiocarcinoma (ICC) usually have short survival due to a lack of effective treatment. This multicenter, single arm, open labeled, prospective study was conducted to evaluate the effectiveness and safety of sorafenib combined with best supportive care (BSC) in these patients. We enrolled 44 patients with unresectable and advanced ICC who were treated with sorafenib (400 mg, twice daily) and BSC. The primary endpoint was disease control rate (DCR) at week 12, and the secondary endpoints included time to progression (TTP), progression-free survival (PFS), overall survival (OS), duration of therapy (DOT), and adverse events (AEs). Our results showed that the DCR was 15.9%, the median TTP was 5.6 months, and the median PFS and OS were 3.2 and 5.7 months (95% confidence interval [CI]: 2.4-4.1 months; 3.7-8.5 months), respectively. The median DOT was 1.8 months (95% CI: 1.9-3.9 months). AEs of grades 1 and 2 events occurred in 75% of patients, and AE of grade 4 (severe) was observed in 1 patient. Therefore, sorafenib in combination with BSC had an acceptable DCR and safety profile in patients with unresectable and advanced ICC.
