The research team has demonstrated that leukaemic cells can be eradicated by removing a carbohydrate modification displayed on the cell's surface.
Director of Griffith University's Institute for Glycomics, Professor Mark von Itzstein is the Australian team leader. He said the discovery is an important advance against leukemia, a cancer of malignant white blood cells that multiply uncontrollably. Acute lymphoblastic leukemia (ALL) is the most common childhood cancer.
"We have found that the leukaemic cell has an altered cell surface carbohydrate decoration compared to normal cells and this also conveys resistance to drug treatment," Professor von Itzstein said.
"We have now shown that with the removal of this carbohydrate alteration the cells die."
Professors Nora Heisterkamp and John Groffen, leaders of the US-based team, Professor von Itzstein and their colleagues have published their research findings in the latest edition of the Journal of Experimental Medicine.
Professor von Itzstein said the research could lead to new ways to fight the disease, particularly where it has become treatment resistant.
"Up until 40 years ago, only one child in five survived ALL," but advances in chemotherapy have changed that outcome and now nearly 80 percent of children with ALL will be cured," Professor von Itzstein said.
"For the remaining 20 percent, however, the disease returns necessitating additional rounds of intensive chemotherapy. Unfortunately, most relapsed patients die within one year because their cancer cells are resistant to chemotherapy.
