Cure of leukemia after hematopoietic stem cell transplantation (HSCT) is sustained by the
anti-leukemic effect of the grafted cells (graft-versus-leukemia (GVL)). However, it is not
known whether the tumor-immunity is affected by photochemotherapy (psoralene
photosensitization and ultraviolet light radiation) administered to attenuate graft-versus
host disease (GVHD).
The present study aim to investigate what happens to the GVL after photochemotherapy of aGVHD
in a predominantly retrospective setting with 10-years follow-up after HSCT
