A trial looking at chemotherapy for people with rectal cancer (Copernicus)
We know that this is an especially worrying time for people with cancer and their family and friends. We have separate information about coronavirus and cancer. Please read that information alongside this page. We will update that information as guidance changes.
This trial looked at whether it was useful for people with cancer of the back passage (rectal cancer) to have chemotherapy before surgery.
Cancer Research UK supported this trial.
More about this trial
Radiotherapy, followed by surgery and chemotherapy is the usual treatment for rectal cancer. This is
Research has shown that for some cancers giving chemotherapy before and after surgery can help to delay the cancer coming back.
In this trial doctors gave people the same amount of radiotherapy and chemotherapy as standard treatment. But some of the chemotherapy was given before surgery.
The researchers wanted to find out
- if it was possible to give chemotherapy before surgery
- if having chemotherapy before and after surgery helped to delay rectal cancer coming back
- about the side effects
Summary of results
The trial team found it was possible to give chemotherapy before surgery to remove rectal cancer.
This was a phase 2 trial. Everyone had chemotherapy before surgery to remove their rectal cancer.
60 people joined the trial. 3 people didn’t have surgery.
57 people had chemotherapy, radiotherapy then surgery. The average gap between finishing their radiotherapy and having surgery was 7 days.
The cancer was completely removed in all 57 people.
After surgery 45 people had more chemotherapy and 12 didn’t.
The researchers have followed up the people who had surgery for at least 1 year after surgery to see how they are.
The worst side effect of the chemotherapy and radiotherapy before surgery was a significant drop in white blood cells causing an increased risk of infection.
The trial team concluded that it is possible to give chemotherapy before surgery for rectal cancer. A larger phase 3 trial is being considered to study this further.
