Last year in the UK over 60,000 cancer patients enrolled on clinical trials aimed at improving cancer treatments and making them available to all.
A study looking at how bacteria in the gut affects treatment for pelvic cancer (PELICAN-23)
This study is looking to see if gut bacteria (the

The natural bacteria that live in your mouth and gut is the microbiome. There are lots of bacteria in our gut. We know that they are important for keeping us healthy. We also know from research into other cancers that bacteria normally living in our bowels change the way our body fights the cancer cells.
The researchers in this study are looking to see if this also happens in cancers that start in the pelvis or bowel. To do this they will look at:
- poo samples
- blood samples
They analyse the poo samples for the types of bacteria in them and how they might interact with your body.
The main aims of this study are to find out:
- whether the gut microbiome can predict how well treatment works
- if different types of cancer have different bacteria in the bowel and if these bacteria change how treatment works

- You are at least 16 years old.
Who can’t take part
You cannot join this study if you have another cancer.
This study is taking place at the Aberdeen Royal Infirmary. The team need 450 people to take part.
You give a poo sample before you start treatment or early on in your cancer treatment.
The team give you the kit to collect the poo sample at home. The kit includes instructions on how to collect the sample. You drop it off at the hospital at your next hospital visit.
If you have bowel cancer the team may ask to take some samples at the time of your operation. Your surgeon will collect these.
The team also ask to access a blood sample which you may already have had taken as part of your treatment. They plan to use some of the blood for this research. You don’t need to have any extra blood samples as part of this study.
There are 2 food questionnaires. The team ask you to choose one to complete. The first one is called a food frequency questionnaire. It asks you to give details of the types of foods you have had over the last 3 months. It also asks if you take any diet supplements. The questionnaire takes about 20 to 30 minutes to complete.
The second questionnaire is a food diary. This involves keeping a record of all the food you have over a period of 4 days. You complete it for 4 days before you give the poo sample. The diary asks you to give details of the foods you have and to estimate portion sizes.
You don’t have to complete these questionnaires if you don’t want to. It won’t affect you taking part in the rest of the study.
You return the questionnaires to the hospital when you have your next hospital visit.
The team will ask to collect information from your medical records. This includes:
- any medications you take
- the type of cancer you have
- what cancer treatment you had
- how your treatment worked
The team continue to access your medical records now and again. They do this for up to 5 years after your cancer treatment finishes. This allows the team to compare the results of your poo bacteria analysis with how your treatment worked.
You might have an extra hospital visit if you join this study to sign the
There aren’t any side effects from taking part in this study.
Your doctor and nurses monitor you during treatment and afterwards. Contact your advice line or tell your doctor or nurse if any side effects are bad or not getting better. We have information about:
