Brief Summary
In consideration of the fact that the vascular endothelium has been shown to be a target of GvHD in early stage and that the count of CEC may represent a marker of endothelial damage, we want to evaluate the changes in CEC counts of patients affected by hematological disorders undergoing allo-HSCT, as a function of endothelial damage. We will enroll 50 patients affected by hematologic disorders undergoing allo-HSCT. Peripheral blood will be drawn before (T1, baseline) and at the end of the conditioning regimen (T2, pre-transplant), upon confirmation of hematopoietic recovery (T3, engraftment) and thereafter at onset of GVHD (GVHD T4) and one week after the start of steroid therapy (T5, post-GvHD). All patients will also be checked for CEC at day + 28. CEC enumeration will be performed by using the CellSearch® System and a flowcytometry procedure. Through the conduct of this study, we expect to confirm our preliminary results on a larger series of patients, and to evaluate the predictive role of CEC on the occurrence of GvHD and prognostic response to treatment of GvHD. The possibility of early identification of patients who do not respond to traditional treatments of GvHD, and for this reason at a higher risk of morbidity and mortality, may allow greater individualization of the therapeutic program, for example with the introduction as early as possible of alternative treatments. In addition, the identification of patients at higher risk of non-responsiveness to steroid treatment, would allow, through a closer monitoring, the early introduction of additional treatment before the development of resistance/refractoriness to treatment of GvHD. The present study takes the form of a prospective study. The primary endpoint is the identification and enumeration of CECs in peripheral blood of patients with hematological disorder undergoing allo-HSCT, as a function of endothelial damage. The secondary endpoint is to define the prognostic and predictive value of the changes of CEC counts on the diagnosis of GvHD and response to treatment.

Outcome Measures
Primary Outcomes (1)
Changes from baseline (Timepoint 1) in Circulating Endothelial Cell (CEC) count at GvHD onset (Timepoint 4)
CEC count changes will be evaluated between baseline and time of GvHD onset, within day + 100 post-transplant. In our preliminary series of 40 patients GvHD have manifested at a median of 27 days post-transplant (range 15-103).
Basal (Timepoint 1) versus GvHD onset (Timepoint 4)
Secondary Outcomes (3)
Changes from baseline (Timepoint 1) in Circulating Endothelial Cell (CEC) count at time of transplant (Timepoint 2)
Basal (Timepoint 1) versus pre-transplant (Timepoint 2)
Changes from baseline (Timepoint 1) in Circulating Endothelial Cell (CEC) count at time of engraftment (Timepoint 3).
Basal (Timepoint 1) versus engraftment (Timepoint 3)
Changes from GvHD onset (Timepoint 3) in Circulating Endothelial Cell (CEC) count at one week after the start of steroid therapy (Timepoint 5).
GvHD onset (Timepoint 3) versus one week after the start of steroid therapy (Timepoint 5)
Study Arms (1)
Patients undergoing allo-HSCT, who manifest GvHD.
Patients undergoing allo-HSCT, that manifest GvHD. Patients undergoing allo-HSCT will have CEC count performed at the following timepoints: T1 (baseline), T2 (pre-transplant), T3 (engraftment), T4 (GvHD onset) and T5 (post-GvHD). All patients will also be checked for CEC at day + 28.
