This study recruited 231 people with
Hodgkin lymphoma (HL). The research team took blood samples from most of the people taking part. They also looked at lymph node samples that were taken at diagnosis, if they were available.
These samples, along with samples from people who took part in other trials, have been looked at by various research teams. They compared them to blood and tissue samples of people who don’t have HL. These are called the controls. The researchers wanted to try and find out more about what causes HL.
They have looked at a number of things. They are trying to find out why some people develop Hodgkin lymphoma and others don’t, and more about the best way to treat it.
They have discovered a number of interesting things so far, including finding:
- several new genes that may increase the risk of developing HL
- out more about cells in the immune system called T cells, comparing lymph nodes of people with and without HL
- the differences between the genes in HL that is associated with the Epstein Barr virus (EBV), and HL that isn’t
- the proteins in HL cells which affect how the cells divide and grow
They also looked at other conditions that may be related to HL, including finding out:
- more about the importance of the EBV in the development of HL
- that the differences in how HL behaves depends on whether it is associated with EBV or not
- that having the measles virus does not appear to be related to the development of HL
- that a group of viruses called polyomaviruses don’t appear to increase the risk of developing HL
Hodgkin lymphoma is a complex disease, and finding out about what makes it develop and grow takes a long time. Research teams from all over the world, including the UK, are working hard to find out more about it and help people who are diagnosed in the future.
We have based this summary on information from the research team. The information they sent us has been reviewed by independent specialists (
peer reviewed 
) and published in a medical journal. The figures we quote above were provided by the trial team who did the research. We have not analysed the data ourselves.
