The Efficacy and Safety of Apatinib Treatment for Patients with Unresectable or Relapsed Liver Cancer: a retrospective study

摘要

Purpose: Liver cancer is insensitive to chemotherapy. Sorafenib is currently the standard treatment for patients with advanced diseases, with mild survival extension and several intolerable drug-related side effects. The establishment of new treatments is an unmet clinical need. The aim of our study was to assess the efficacy and safety of apatinib, a novel antiangiogenic drug, in the treatment of patients with liver cancer. Materials and Methods: Patients with unresectable or relapsed liver cancer were included in a single center, retrospective, observational study and treated with apatinib until progressive disease or unacceptable toxicity. Results: 32 patients were reviewed from January 2015 to March 2017. No complete response (CR) occurred, 5 patients (16%) showed partial response (PR), 14 patients (44%) had stable disease (SD), 13 patients (41%) had progressive disease (PD), with disease control rate of 60%. Median progression-free survival (PFS) was 5 months (95% confidence interval [CI]: 4.3-6.1 months) for hepatocellular carcinoma (HCC) and 3 months (95% CI: 2.5-4.2 months) for intrahepatic cholangiocarcinoma (ICC). The median overall survival (OS) was 13 months (95% CI: 12.4-14.1 months) for HCC and 5 months (95% CI: 4.5-6.2 months) for ICC, respectively. The most common adverse effects (AEs) were proteinuria (31%), secondary hypertension (28%) and liver dysfunction (13%). Conclusion: Apatinib treatment was an effective for patients with liver cancer. The toxicities were mild and tolerable.
