Survival Data at 1, 2, and 3 Years according to EASL Criteria

Note.—Unless otherwise noted, data are mean survival rates (in percentages) ± standard errors of the mean. Among patients who did not respond to initial chemoembolization according to EASL criteria, those who responded to the second chemoembolization had significantly better 1-, 2-, and 3-year survival rates than did those who did not. N1 = patients who did not respond to the first chemoembolization, R1 = patients who responded to the first chemoembolization, N1N2 = patients who did not respond to either the first or second chemoembolization, N1R2 = patients who did not respond to the first chemoembolization but did respond to the second chemoembolization, R1N2 = patients who responded to the first chemoembolization but not to the second chemoembolization, R1R2 = patients who responded to both the first and second chemoembolizations.

^*Standard error of the mean was unavailable because only one patient was in the last risk set.

^†P = .005 for the survival comparison of 3 years for N1R2 group versus 788 days for N1N2 group, so P = .005 for the comparison of 3 years for N1R2 group versus 3 years for N1N2 group.
