Overall survival curves for different groups.
Notes: The mean and median survival time for Lipiodol® (Guerbet, Villepinte, France) (Group A, n = 16), nanoplex/Lipiodol (Group B, n = 25), nanoplex-p53/Lipiodol (Group C, n = 30), nanoplex-Rb/Lipiodol (Group D, n = 25), and nanoplex-(p53+Rb)/Lipiodol (Group E, n = 25) are 39.7 and 39.0 days, 52.8 and 52.0 days, 60.4 and 59.0 days, 49.8 and 50.0 days, and 60.0 and 61.0 days, respectively. Log-rank testing showed that Groups B, C, D, and E all had a significantly longer survival time than Group A (all P = 0.000). Groups C and E could prolong the survival time longer than Group B (all P = 0.000) and Group D (C versus D, P = 0.003; E versus D, P = 0.005). There was no significant difference in survival prolongation between Groups B and D (P = 0.462) or between Groups C and E (P = 0.500).
