Genetic markers show the way to the most effective leukaemia treatment

Richard Rosenquist Brandell conducts research into how leukaemias arise, and how genetic markers can be used to assess prognosis and to select the most effective treatment. His research focusses primarily on chronic lymphatic leukaemia, CLL.

A third of patients diagnosed with CLL, chronic lymphatic leukaemia, have mild symptoms and will never need treatment. Others need immediate treatment and are at high risk of dying early from the disease. Richard Rosenquist Brandell is focusing his studies on how CLL arises, and how it could be possible to predict the various forms of the disease at an early stage.

“We want to understand which genetic changes characterise the various subgroups of the disease, from the mildest form to the most aggressive,” he says. “This will enable early and more correct risk assessment, as well as choosing the correct treatment for the individual patient. We are beginning to see a future in which we can treat CLL completely without the use of cytostatic drugs by combining small molecule inhibitors. This would be an important advance for the patients.”

Richard Rosenquist Brandell is one the leaders of an internatio¬nal consortium comprised of 24 research institutes with a total of 30,000 CLL patients.

“The very large size of this material gives us unique opportunities to find new associations. We have identified more than one hundred subgroups of the disease, of which 19 are large, and we are now investigating them carefully using the new sequencing techniques,” he comments.

In his research on the origins of CLL, Rosenquist Brandell has focussed on the B-cell receptors. His group has demonstrated that different antigens’ interaction with the receptors is key for the development of the disease. As a clinician, he is also committed to applying modern sequencing techniques in healthcare.
