Aggressive B-cell lymphomas are the most common form of lymphoma and ~50% of patients are cured with modern treatments. However, the outcomes for patients whose disease is not cured are dismal with ~10% of those patients alive at 5 years. This shows that these lymphomas, although grouped together on the basis of what they look like down the microscope, represent clusters of different lymphoma groups. A better understanding of the 'molecular wiring'of these lymphomas is critical to identify patients at high risk of resistant lymphoma and providing better treatments.
This project will provide a rational new way to group lymphomas based on differences in the molecular wiring. This will be acheived by performing and analysing genomic sequencing on a large number of aggressive B-cell lymphomas brought together through an international lymphoma consortium. Further, tumour samples will be analysed from the time of diagnosis and when the lymphoma relapses to see whether this molecular wiring remains stable or changes with treatment. It is anticipated that this major step forward in our knowledge will be translated into new tools for matching a patient's lymphoma to the correct treatment and improving patient outcomes.
