Photochemotherapy of Acute Graft-versus-host Disease (aGVHD) of the Skin - is Graft-versus-leukemia Preserved in Patients Transplanted for Acute Leukemia?
In Brief
An observational study evaluating Photochemotherapy for ALL and 3 related conditions. Completed, enrolled 47 participants across 1 site.
Detailed Summary
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

Timeline
Interventions
Oral 8-Methoxypsoralene (8-MOP), (0.4-0.8 mg/kg), are given 1.5-2 hours before phototherapy. Ultraviolet light type A (UVA, 320-400 nm) is administered in a Waldmann UV1000 supine unit through 26 100-W fluorescent PUVA lamps (Waldmann F85), if needed, UVA is given in a half body unit with 15 100-W PUVA-lamps (Waldmann F85), (Waldmann UV3003K), (Waldmann, Villingen-Schwenningen, Germany). Eye protection is applied during 24 h after oral 8-MOP and the genital area are shielded in males during therapy.The UVA is initiated at 0.2-1.5 J/cm2 and is amplified by 0.25-0.5 J/cm2 after two treatments if photo toxicity is absent. PUVA is given to the patients 3-5 times each week.
