PTCy provides a suitable platform for exploring adoptive immunotherapy after both myeloablative and nonmyeloablative conditioning.
Early and sequential prophylactic G-CSF–mobilized DLI (G-DLI) after myeloablative conditioning improves progression-free survival with a modest increase in mild to moderate chronic GVHD.
NK cell alloreactive donor improves outcome after myeloablative conditioning, but prophylactic G-DLI improves the outcome irrespective of NK cell alloreactivity.
