Around 1 in 5 people diagnosed with cancer in the UK take part in a clinical trial.
A study looking at biomarkers in people with kidney cancer
This study looked at chemicals and proteins called biomarkers in the blood and urine of people with kidney cancer (renal cell cancer).
This trial was open for people to join between 2011 and 2013. The team reported the results in 2020.
More about this trial
Doctors know that people with kidney cancer have
The aims of this study were to find out more about these biomarkers to:
- help diagnose kidney cancer
- help monitor treatment
- try and improve treatment in the future
Summary of results
The study team found that it would be enough to take the sample once. But they need to analyse the sample twice, to correct for technical differences. They found it gave a starting point measurement for the protein biomarker. This measurement is called a baseline measurement.
About this study
The study team took blood and urine samples from people twice. They took them:
- when they joined the study
- and again between 2 and 21 days later
The team looked at 16 possible biomarkers. The team compared these levels:
- within the person themselves, and
- between the people who took part
They found that there was less variability in the samples from the same person. This is in comparison to when they compared the samples of all the people taking part.
Kidney cancer grows new blood vessels so it can get the oxygen and nutrients needed to grow. The researchers wanted to find biomarkers that show if this is happening. And to show how well treatment to block this blood vessel growth is working. These blood vessels also transport
There is an interest in these biomarkers and how they can show the interaction between the immune system and the cancer. Also
The study team concluded that testing once is enough to establish a baseline measurement for biomarkers. They hope that this will be useful for many doctors when they are considering treatment for kidney cancer. And that it is also useful for other researchers investigating kidney cancer.
