Even after chemotherapies and stem cell transplants, relapses still occur in leukemia patients. that study established a mouse model after bone marrow transplant and found that the immunization of mice with leukemia-cell-derived heat shock protein 70 (HSP) induced leukemia-specific immunities and prolonged their survival.

The tumor-derived-HSP binds the tumor-specific antigenic peptides, making it an effective cancer vaccination. It has reported that patients with peptide-specific antibodies survived longer than those without.

Using leukemia-specific antibodies induced by HSP-based vaccination would be useful for the prognosis of leukemia and facilitate the establishment of novel therapeutic strategies in the future.
