Of the 119 patients in the 600-mg dose group, 24 have died, and overall survival was censored for the remaining 95; 1 of these 95 patients discontinued therapy with imatinib to undergo BMT. Of the 62 patients in the 400-mg dose group, 27 have died, and overall survival was censored for the remaining 35; 1 of these 35 patients discontinued treatment with imatinib to undergo BMT. The difference between dose groups was statistically significant (P = .014, log-rank test).
