Research - clinical trials for brain tumours
Cancer research trials are carried out to try to find new and better treatments for cancer. Trials that are carried out on patients are known as clinical trials.
Clinical trials may be carried out to:
Trials are the only reliable way to find out if a different operation, type of chemotherapy, radiotherapy, or other treatment is better than what is already available.
Taking part in a trial
You may be asked to take part in a clinical trial. There can be many benefits in doing this. Trials help to improve knowledge about brain tumours and develop new treatments. You'll also be carefully monitored during and after the study. Usually, several hospitals around the country take part in these trials. It's important to bear in mind that some treatments that look promising at first are often later found not to be as good as existing treatments, or to have side effects that outweigh the benefits.
If you decide not to take part in a trial your decision will be respected and you don't have to give a reason. There will be no change in the way that you're treated by the hospital staff and you'll be offered the standard treatment for your situation.
Blood and tumour samples
Many blood and bone marrow or tumour samples may be taken to help make the right diagnosis. You may be asked for your permission to use some of your samples for research into cancer. If you are taking part in a trial you may also be asked to give other samples which may be frozen and stored for future use when new research techniques become available. These samples will have your name removed from them so you can't be identified.
The research may be carried out at the hospital where you are treated, or it may be at another hospital. This type of research takes a long time, so you are unlikely to hear the results. The samples will be used to increase knowledge about the causes of cancer and its treatment. This research will hopefully improve the outlook for future patients.
