Acute lymphoblastic leukaemia: making treatment even better

Published on 2 December 2015

Around 300 children develop a type of cancer called acute lymphoblastic leukaemia (ALL) each year in the UK.1 This cancer is most common in young children who are less than five years old. Most children with ALL are cured. However, treatment has side effects and some children still lose their lives. Dr Owen Williams, of University College London’s Institute of Child Health, is searching for new treatments for children with a common type of ALL in the hope of reducing side effects and saving more children’s lives.

Action Medical Research and Great Ormond Street Hospital Children's Charity are jointly funding this research.‚Äč

How are children’s lives affected now?

ALL is the most common type of cancer to affect children.2 It’s an aggressive cancer that develops rapidly, so urgent treatment is needed, but with today’s care children with ALL have a high chance of surviving. Treatment usually involves chemotherapy and steroids, but radiotherapy and sometimes a bone marrow transplant can also be needed.

“Although the outlook is normally very good for children with ALL, it remains important to look for ways to improve treatment,” says Dr Williams. “Children have to go through intensive treatment, which typically lasts for years and can cause unpleasant side effects. Sadly, a small number of children with this type of cancer still die.”

“Possible side effects during treatment include nausea, vomiting, tiredness and hair loss,” continues Dr Williams. “Some children also have problems later in life. For example, their growth might be restricted, they may be infertile and their ALL can recur.”

How could this research help?

The researchers are searching for new drug treatments for a type of ALL that’s called TEL-AML1, after the cancer gene that causes it. One in four children with ALL has this.3

“We’ve discovered that the TEL-AML1 cancer gene turns on a particular pathway inside cancer cells that the cells need to survive,” says Dr Williams. “We’re therefore looking for drugs that turn off this pathway and investigating whether they destroy cancer cells in the laboratory.”

“We’re focusing on drugs that are already used to treat other illnesses,” says Dr Williams. “This speeds up the development process, because information on the safety of those drugs is already available.”

“We hope to find a drug that can be used alongside chemotherapy, so the intensity of chemotherapy can be reduced,” continues Dr Williams. “Our ultimate goal is to spare children from some of the side effects of chemotherapy and protect more children from relapses.”
