This trial looked at having chemotherapy after surgery to improve treatment for cancer of the kidney and .
It was for people whose cancer had grown into surrounding tissue or nearby . This is called locally advanced cancer.
This trial was open for people to join between 2012 and 2017. The trial team published the results in 2020.
Cancer Research UK supported this trial.
The usual treatment for transitional cell cancer of the kidney and ureter is surgery. The surgery removes both the kidney and ureter. The ureter is the tube that takes urine from the kidney to the bladder.
When this trial was done, you didn’t have chemotherapy after surgery. You had regular check ups to monitor the cancer. You had chemotherapy only if the cancer started to grow again.
But in some similar types of cancer, having chemotherapy after surgery delayed the cancer coming back. This is called adjuvant chemotherapy. So researchers wanted to see if adjuvant chemotherapy would work for cancer of the kidney and ureter.
In this trial, some people had chemotherapy after surgery. And some had regular check ups as usual to monitor the cancer.
The main aims of the trial were to:
The trial team found that having chemotherapy after surgery worked well. It delayed the cancer coming back for longer. And the side effects were manageable.
About this trial
This was a phase 3 trial. It took place in the UK. 261 people took part.
Everyone had surgery to remove their kidney and ureter as planned. They were then put into 1 of 2 treatment groups at random.
Neither they nor their doctor could decide which group they were in.
In the chemotherapy group, they had 1 of the following:
They had up to 4 cycles of treatment.
People in group 2 could go on to have chemotherapy if their cancer came back. But this wasn’t part of the trial.
Results
The committee that monitors the safety and design of the trial (the data monitoring committee) did a planned early analysis of the results. This was to check how treatment was working.
The results showed that having chemotherapy worked better than not having chemotherapy. So the trial was stopped early. This was so the trial team could share the results. And people could start chemotherapy if they were suitable to have it.
The trial team followed everyone up for an average of 30 months. They worked out that having chemotherapy could reduce the risk of dying or of the cancer coming back by just over half (55%).
The trial team looked at the number of people who were alive and had no signs of cancer. They worked out that at 3 years this could be:
They also looked at the number of people who were alive and whose cancer hadn’t spread elsewhere in the body. They found this was:
The trial team plan to look at how long people live. This is called overall survival. We’ll add these results when they are available.
Quality of life
The trial team looked at how having chemotherapy affected quality of life. Everyone filled in a questionnaire at set times during treatment and afterwards. The questionnaire asked about side effects and how people had been feeling.
They compared the results of the 2 groups. They found people who had chemotherapy had a lower quality of life during chemotherapy. And for up to 3 months afterwards. But their quality of life improved. And by 6 months there was no difference between the 2 groups.
Side effects
The side effects of chemotherapy were as expected. Some of the more serious side effects included:
The trial team say the side effects were manageable.
Conclusion
The trial team concluded that having chemotherapy after surgery worked well. And that it should be considered as a new standard of care for transitional cell cancer of the kidney and ureter.
