Text: Double treatment produced better outcome in terms of event-free survival (median 22 vs 21 months, 28 % vs 14 % at 4 years and 15 % vs 7 % at 6 years after randomization ; logrank p = 0. 013 ; univariate HR 0. 74, 95 % CI, 0. 58-0. 94), progression-free survival (median 27 vs 24 months, 33 % vs 16 % at 4 years, and 17 % vs 9 % at 6 years after randomization ; logrank p = 0. 006 ; HR = 0. 71, 95 % CI 0. 56-0. 91), but not overall survival (median 50 vs 55 months, 52 % vs 56 % at 4 years and 39 % vs 36 % at 6 years after randomization ; logrank p = 0. 51 ; HR = 1. 10, 95 % CI 0. 83-1. 46).
