Around 1 in 5 people diagnosed with cancer in the UK take part in a clinical trial.
This trial was for people whose follicular lymphoma had come back after earlier treatment (relapsed).
Cancer Research UK supported this trial.
Follicular lymphoma is the most common type of non-Hodgkin lymphoma (NHL). CHOP chemotherapy and a called rituximab is the usual treatment. This is known as R-CHOP. Sometimes, doctors use radiotherapy too, but this combination of treatments can cause a lot of side effects.
Having a shorter course of chemotherapy and adding a drug called Zevalin (instead of radiotherapy) may cause fewer side effects.
Zevalin (ibritumomab) is a 'radio labelled' monoclonal antibody. This means it has a radioactive molecule called yttrium 90 attached to it. The antibody finds lymphoma cells by seeking out a protein called CD20 on the cells’ surface. The radioactive yttrium (pronounced it-ree-um) then kills them.
The aims of this trial were to find out
The trial team found that having a shorter course of chemotherapy and Zevalin was a useful treatment for follicular lymphoma that had come back.
50 people had a shorter course of chemotherapy and rituximab. So everyone had
followed by Zevalin.
8 weeks after having Zevalin the researchers looked at how well treatment had worked. They found that for:
For 3 people a complete response may have occurred but this was not confirmed.
The people who took part had regular check ups. At the check ups the trial team found that:
The researchers looked at the average length of time people lived without any signs of their cancer getting worse. This is called progression free survival. This was just under 2 years (23.1 months).
They also looked at how long people lived after treatment. At 5 years, around 8 out of 10 people (77.5%) were still alive.
The main side effects were easily managed. They included:
The trial team concluded that a shorter course of chemotherapy and Zevalin was a useful treatment for this group of people. And the side effects weren’t too bad.
We have based this summary on information from the research team. The information they sent us has been reviewed by independent specialists () 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.
