New Improved Diagnostic Marker For Severe Blood Cancer

Mantle cell lymphoma is an aggressive form of blood cancer that most commonly

afflicts older men. Accurate and early diagnosis is crucial to select an optimal

treatment and to increase the chances for survival. A research team at Lund

University has now found a novel way to diagnose mantle cell lymphomas (MCL).

The novel approach that will be tested in the routine diagnosis of lymphoma in

the Department of Pathology is based on a new biomarker, i.e., a factor that is

specific for a certain disease. The discovery is a result of research within

CREATE Health, a Center for Translational Cancer Research supported by the

Foundation for Strategic Research and the Wallenberg Foundation.

CREATE Health has integrated investigators from the faculties of medicine,

engineering, and natural sciences together with clinical oncologists from the

university hospital. The overall aim is to identify proteins and genes that can

be used as biomarkers for cancer, using emerging advanced technologies. Several

very promising projects are under development, but the novel diagnostic approach

for MCL has advanced the furthest. Scientist Sara Ek and colleagues have by

studying more than 50,000 gene fragments found those that are specifically

overexpressed in this disease. She has also identified the corresponding

proteins and it is one of these proteins that serves as a specific biomarker.

- In a collaboration with pathologists, we are now studying the biomarker to see

if it can be used as a novel routine test for this aggressive blood cancer. In a

longer perspective, knowledge about the function of these disease-specific

proteins can also lead to novel therapeutic modalities for blood cancer,

explains professor Carl Borrebaeck, program director for CREATE Health.

Dr. Dictor, pathologist at Lund University Hospital agrees.

- The biomarker Sox11 has shown to be a very sensitive and specific marker for

MCL in addition to providing new information on how the disease might arise.
