A trial looking at chemotherapy after surgery for pancreatic cancer (ESPAC 3 v2)
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.
Many pancreatic cancers start in the cells lining the ducts inside the pancreas and are known as ductal cancers. But a small number start in a part of the pancreas called the ampulla of Vater. As this is quite rare, there is not a
Doctors can sometimes treat pancreatic cancer with surgery. But even if the cancer is removed, there is a chance that it could come back. Having chemotherapy after surgery may stop this happening. Gemcitabine is the chemotherapy drug that is most often used to treat ductal pancreatic cancer. In this trial, researchers compared it with another drug called fluorouracil.
The aim of this trial was to see which drug helped people with ductal pancreatic cancer to live longer after surgery.
The trial also looked at whether either type of chemotherapy helped people with pancreatic cancer that started in the ampulla of Vater.
Summary of results
The researchers found that people with ductal cancer lived for about the same length of time whether they had fluorouracil or gemcitabine.
The trial recruited 1,088 people with ductal cancer in a number of different countries. Everybody taking part had surgery to remove pancreatic cancer, followed by up to 6 months of chemotherapy.
- 551 people had fluorouracil and a vitamin called
- 537 people had gemcitabine
The average length of time people lived after surgery was just under 2 years in both groups.
The side effects were different between the groups.
- People having fluorouracil had more serious mouth problems and diarrhoea
- With gemcitabine, more people had a severe drop in the number of blood cells, causing an increased the risk of infection, bleeding problems, tiredness and breathlessness
The researchers asked more than 500 of the people taking part to complete questionnaires about their side effects and how they had been feeling. This is called a quality of life study. People in both groups rated their quality of life about the same.
The trial also recruited 304 people who had pancreatic cancer that started in the ampulla of vater. After having surgery to remove their cancer, they were put into 1 of 3 groups.
- 101 had fluorouracil
- 98 had gemcitabine
- 105 had no chemotherapy
The trial team presented these results at a conference in 2011. They found that although a higher percentage of people who had chemotherapy were alive 5 years after treatment, the difference was quite small and may have happened by chance. But they suggest that as there was some benefit for people having one chemotherapy drug, more trials could look at having a combination of chemotherapy drugs for this type of pancreatic cancer.
Another trial called ESPAC-4 is looking at gemcitabine alongside a tablet form of fluorouracil called capecitabine. The aim is to see if this combination of the 2 drugs helps people more than gemcitabine alone after surgery for pancreatic cancer.
