In univariate and multivariate analysis, patients with age over than 60 or stable primary liver mass showed the better OS and TTP. The patients with partial response or stable disease also had better survival outcome but not in time to progression in multivariate analysis. PR: Partial response; PD: Progressive disease. OS: Overall survival: TTP: Time to progression.
