This trial was trying to find out if drug called imatinib (Glivec) could stop or delay a gastrointestinal stromal tumour (GIST) from coming back after surgery.
A gastrointestinal tumour (GIST) is a rare type of that is found in the
.
Most people who have a GIST will have surgery to remove it and this may cure it completely. But sometimes the cancer will begin to grow again. It may come back in the same place, or it may start to grow somewhere else in the body.
Imatinib is a type of biological therapy called a tyrosine kinase inhibitor or TKI. It stops signals that cancer cells use to divide and grow.
People who have a GIST that cannot be removed with surgery have treatment with imatinib. It often shrinks the tumour, helping to relieve symptoms. And it helps these people to live longer. But doctors didn’t know if it would also help people who'd had a GIST removed with surgery.
Having a treatment after surgery to try to stop cancer coming back is called .
The aims of this trial were to
The researchers found that in the first few years after surgery, GIST came back in fewer people who had imatinib.
The trial recruited 908 people
The trial team found that more than 1 in 6 people (17%) who took imatinib stopped the treatment because of side effects or because they didn’t want to carry on taking it.
The researchers looked at the number of people who were living without any signs of their sarcoma having come back after 3 years. They found this was
After an average follow up period of nearly 5 years, they looked at the number of people whose tumours hadn’t become to imatinib. They found this was
They also looked at the number of people who were still alive after 5 years and found this was
The trial team concluded that 2 years of adjuvant imatinib helped to stop GIST coming back in the short term (3 to 5 years).
