Even after chemotherapies and stem cell transplants, relapses still occur in leukemia patients. This 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.

About Cancer Science

Cancer Science (formerly Japanese Journal of Cancer Research) aims to present research that has a significant clinical impact on oncologists or that may alter the disease concept of a tumor. The Journal publishes original articles and editorials, letters to the editor, review articles and reports describing original research in the fields of basic, translational and clinical cancer.

Subject categories include:
-- carcinogenesis
-- tumor biology and pathology
-- molecular biology and genetics
-- epidemiology and prevention
-- immunology and virology
-- experimental therapeutics
-- clinical medicine
