About

The rationale of this study is to determine if an association exists between WT1 expression and relapse occurrence in patients with acute myeloid leukemia submitted to allogeneic stem cell transplantation. In particular, we want to studied WT1 expression level on bone marrow samples of day +60 in terms of predicting power on relapse incidence so as to determine a cut-off value for identify high risk patients.

Full description

This is a retrospective study which will be held on 50 patients with acute myeloid leukemia allografted in the transplant Units of Policlinico Agostino Gemelli in Rome, between June 2018 and July 2020, for whom WT1 level was assessed on bone marrow at day 60 after transplant. The minimum follow up for surviving patients will be 60 days. Patients will be classified according to European Leukemia Net criteria. For each patient a total of 24 ml of bone marrow was collected at day +60 post transplant, whereas the same quantity of bone marrow was collected from healthy donor during bone marrow harvest procedure.
