Scientists have advanced the therapy to fight against acute lymphoblastic leukemia in children.
According to scientists, the discovery will have a big impact on treating the most common form of blood cancer.
A study showed that children whose acute lymphoblastic leukaemia (ALL) returns have a higher chance of survival if given the drug mitoxantrone.
After three years on it, 69 per cent of child victims were still alive compared to just 45 per cent on current standard treatment, idarubicin.
"These striking results offer hope to many families across the country," the Daily Express quoted Cancer Research UK expert Vaskar Saha, as saying.
More children die from leukemia than any other cancer and ALL accounts for eight in 10 cases.
