Time to progression for patients with acute lymphoblastic leukemia.

The time-to-progression analysis included all 48 patients with ALL. At the time of analysis, 41 patients had documented progression, and 7 were censored: 5 patients discontinued therapy within the first 2 months to undergo bone marrow transplantation (BMT) procedures and were censored at the time of discontinuation; 1 patient was censored after receiving interferon alfa after 7 months on the study, and 1 patient was progression-free and receiving treatment after 11 months on the study. The estimated median time to progression was 2.2 months with 95% CI = 1.8-2.8 months.
