SECONDARY outcome

Timeframe: 5 years

Population: Analysis was per protocol for 73 patients out of 80 patients due to 3 early deaths and 4 non engraftments.

Tacrolimus and Methotrexate used for acute graft versus host disease (aGVHD) prophylaxis, clinical grading AGVHD criteria (Days 1-100): Grade 1: + to ++ skin rash; no gut involvement; no decrease in clinical performance status; Grade 2: + to +++ skin rash; + gut involvement and/or + liver involvement; mild decrease in performance status; Grade 3: ++ to +++ skin rash; ++ to +++ gut involvement and/or ++ to ++++ liver involvement; marked decrease in performance status; Grade 4: Similar to Grade 3 with ++ to ++++ organ involvement and extreme decrease in performance status.
