The Galleri multi-cancer blood test: What you need to know

by Harry Jenkins | Analysis

A blood test that has the potential to detect over 50 kinds of cancer is now being trialled in the NHS in England.

The Galleri blood test, developed by the company GRAIL, aims to detect cancers earlier by looking for abnormal DNA shed from cancer cells into the blood.

So far, a lot of the research has been in people who have already been diagnosed with cancer. This study will assess if the test can spot cancer in people without symptoms.

There has been a lot of excitement about the Galleri test, and it’s obvious to see why, but that can sometimes make it difficult to understand the full picture.

Here’s what you need to know.

What’s the Galleri blood test and how does it work?

The Galleri test is a blood test that has the potential of detecting multiple types of cancer. It does this by looking for DNA found in the blood, called cell-free DNA (cfDNA), that’s shed by both tumour cells and healthy cells into the bloodstream.

In order to only pick up on cfDNA that indicates the presence of cancer, Galleri uses modern genetic sequencing technology and artificial intelligence to scan for patterns of chemical changes in the cfDNA that come from cancer cells but aren’t found in healthy cells.

Galleri is only available in the UK in research settings at the moment, because there are important questions that need answering before it’s known if it should be used more widely.

What do we know so far?

Results from studies into Galleri have so far been promising.

GRAIL reports that the test can detect 50 different types of cancer with a false positive rate of 0.5%. This means that in approximately 200 people tested, 1 person would be expected to receive a positive result when they do not have cancer.

In a study involving people who had already been diagnosed with cancer, the test accurately detected cancer in 51.5% of people. This gives an indication of the test’s sensitivity. The Galleri test was able to correctly predict the location of the tumour 89% of the time, which is important for knowing which follow-up diagnostic tests the patient needs to confirm their diagnosis.

A key challenge that this type of test faces is the difficulty in detecting very small quantities of abnormal DNA circulating in the blood.

Because the amount of tumour-derived cfDNA tends to increase as a cancer becomes more advanced, these types of blood tests tend to be better at picking up later stage disease. Based on the results reported so far, the test is not currently that good at picking up stage 1 cancer, where the cancer is small and hasn’t spread to other parts of the body.

What’s more, the number of cancers that have been analysed, particularly for some rarer cancer types, has been very small.

The NHS trial is an opportunity to trial the test in a much larger sample, with longer follow up of patients not testing positive and a chance to answer some of the big questions and iron out some of these limitations.

What’s the NHS study looking at?

The NHS trial will focus on whether the Galleri test can accurately and reliably detect cancer in people who aren’t suspected as having cancer and if it can find cancer at earlier stages than would otherwise have been the case.

It’s being organised by GRAIL in partnership with NHS England and will be run by The Cancer Research UK and King’s College London Cancer Prevention Trials Unit, led by director Professor Peter Sasieni.

Initially, the trial will recruit 140,000 people aged 50 to 77 who will be identified through NHS records and invited to take part.

A crucial consideration is that the research gives information about how acceptable and effective the test is across our diverse population and the team are keen to ensure they recruit participants from different background and ethnicities.

Everyone who takes part in the trial will have annual blood tests for 2 years. Half will have their samples tested using Galleri, and half will have theirs stored for future analysis. Those in the intervention group who receive a positive Galleri blood test result will be referred for further investigations in the NHS.

The trial will see if the test can significantly reduce the number of cancer cases diagnosed late at stages 3 or 4, compared to those whose samples aren’t tested.  It will also help identify the negative impacts of the test. This includes monitoring the number of people who test positive but don’t go on to be diagnosed with cancer and if any cancers are missed by false negatives.

Initial results from this study are expected to be released by 2023. If positive, the study will be expanded to involve around 1 million participants in 2024 and 2025. There will also be longer term follow up of the participants, to see if there were any differences in the number of people dying of cancer in the different groups.

Thinking of joining the trial?

Research is vital to making progress. But there’s a lot to consider when taking part in research, so we’d encourage anyone who receives an invitation to the GRAIL Galleri trial to read the information and decide what’s right for them.

If you do decide to take part, it’s really important that you still report any unusual changes in your health to a GP and consider invitations to NHS cancer screening as you would do normally.

This is because not everyone in the trial will have their blood samples analysed, and the test won’t identify everyone who has cancer.

You can find out more on the NHS Digital website

In a different study, 25,000 people with possible cancer symptoms will also be offered the test once they have been referred to hospital. People taking part in the study (SYMPLIFY) will have their diagnostic test(s) in the normal way, but will also give a blood sample and permission for the study team to check their health records later to see if they were diagnosed with cancer and what appointments and other tests they had.

At the end of the study, having tested the blood with the Galleri test, the team will understand more about how well it works in this group of people.

This will help them to design a trial where they can further explore if the test can be used to decide who needs rapid referral to look for a possible cancer and what diagnostic tests might be appropriate to use.

This might be particularly helpful when patients experience symptoms that could be linked to several different types of cancer.

One to watch

The Galleri blood test has encouraging initial data, and it’s great to see NHS England supporting research on this scale because there are many questions that need to be answered before it could be made available in the NHS, including how useful and effective it is and who it might be best to use it with and when.

It will take time to know if Galleri can make a difference and how it should best be used. And regardless of the results, one test alone is unlikely to get us to the point where all cancers are detected at an early stage. Galleri isn’t the only test of its kind in development – research into different ways of detecting cancer early range from blood tests to urine and even poo tests.

In the past year alone we have seen news of blood and urine tests to detect brain, bladder, ovarian and lung cancers, all at varying stages of development.

And tests like these are just one part of a wider picture of investment and action needed to increase the number of cancers detected earlier.

Other recent innovative approaches, such as Cytosponge, the ‘sponge-on-a-string’ to detect a condition that could lead to oesophageal cancer, and Colon Capsule Endoscopy, a disposable camera that’s small enough to swallow and powerful enough to help rule out bowel cancer, exemplify the huge potential of this research field.

These innovations must be supported by having enough NHS staff, infrastructure and kit to ensure that innovative tests can be made available to everyone who could benefit.

It’s early days for the GRAIL blood test. But it’s so exciting to see this research happening and we look forward to seeing more tests of promise being taken through to trials, pilots and implementation, to drive much-needed benefit for patients.

    I would definitely take part. I think you are very lucky if you or your family have not been affected by Cancer it is more prevalent and affects people of all ages so any test that can help with early diagnosis is really important.

  • Barry Hatcher

    I would be happy to get involved in this trial I am now past 70 and always aware of how cancer can develop without us knowing. Members of my family have been lost to this disease and so anything that will detect cancer early must be a good thing and save lives. For this reason I would always be willing to take part in a trial.

    In October 2013 I passed some blood and went to my GP. I had a blood test that suggested I had nothing to worry about. For the next few months I occasionally passed small amounts of blood until April when I passed a lot. Subsequent hospital investigations showed I had bowel cancer. Luckily it had not spread and surgery and chemotherapy dealt with it. If this test had been available then maybe my cancer would have been found sooner and I would not have risked it spreading. I consider myself extremely lucky that it did not spread as one of my neighbours wasn’t so lucky.

  • Marie

    This is such positive news. I lost both my parents to late diagnosis of cancer when they were in their seventies, then 3 years ago my daughter, aged 24 was diagnosed with cancer, a battle she is still bravely fighting. I would love to be considered for any trails to help this test to become available to all at the earliest opportunity. I turn 60 this summer.

  • Libby

    Both me and my husband are taking part in this, I had breast cancer 4 years ago, and now possibly have thyroid cancer. Always more than happy to take part if it helps others.

  • Elizabeth E Wells
    27 February 2022

    I would be very interested to take part in this exciting new trial. All my close relatives have died of cancer but all different types: colon, lung, bone and brain (my parents and their siblings) so I’m guessing I’ll go from one of them. Im 75 and currently have no symptoms.

  • Mark Davis

    Great to find out if you have 50 different types of cancer. Will you ever get treatment? Preventative healthcare is not how the nhs works. The tories have seen to that

  • Joanne spencer
    27 February 2022

    I think this a great idea and I’m 48 and was 47 in 2021 when I was diagnosed with left top apex lung in in March 2021 and April 2021 the full top left lung was was removed fully. So I’m in remission at moment have my year scan in October 2022 to check cancer that it’s not in my lungs or anywhere else in my body. The blood test to find out is great as my cancer was found with me going for X ray and some other pain I was having. Scary but thankful it was early stage. I really hope I get the blood test one day. Keep up the good work.

    I am a mother of 4 & a grandparent of 10, & a wife of a prostate cancer survivor,. I would be only too ready to take part in this trial for the sake of future generations if at 75 yrs, I am not considered too old!!

  • Jo
    26 February 2022

    As someone with no family history (being adopted) this would be amazing for early intervention. In my 50s now but unlikely to be picked, due to lack of history! Hoping the results are as expected

  • Pat

    I am very happy to read about these tests as have had 5 family members and also close friends affected by Cancer.
    As I fall within the age range for the blood test trial I hope that I can take part.

  • Kath Southworth
    26 February 2022

    This is excellent news. We lost two of our close friends to cancer last year. I am fit and well and will be 74 next month. I would be very willing to take part in the trials. Everything that contributes to detecting cancer and preventing it is extremely helpful.

  • Lorraine frost

    I for one would jump at the chance to take part, it’s going to cut the long lists the nhs are enduring at the moment in scanning departments etc with a simple blood test brilliant

  • Mrs Ida Mary Burrows
    26 February 2022

    I would be willing to take part in the trials as my mother died with ovarian cancer aged 58, and my maternal grandmother also died with ovarian cancer aged 47, her sister, my great Aunt died with breast cancer in her 40s. My maternal Grandfather died with bowel cancer.I have had my ovaries removed to help prevent cancer, but I understand I could be prone to breast cancer, as both cancers are connected. I am now 75 years old.

    I have suffered Prostate cancer in the past and am aware of a recurrence in the same or possibly another cancer type. Any research is vital in helping to diagnose and help eliminate the disease. Successful blood tests are a positive way forward as they are non invasive. I would be interested in taking part in any future trials.

    I will be 50 year old soon, I am a single mum as I Lost my husband few years ago with prostate cancer after a long battle against it. My daughter was only 6 years old.
    I always was so scared about cancer and after my
    Husband passed away I
    Just would do everything I can to help increase research in the area and also if possible discover if I have any kind of cancer and treat it in the early stages as my daughter can’t loose her mother as well.
    I really would like to be part of this trial.
    Thank you.

  • Christine Graham
    25 February 2022

    This is an amazing development in the research you are doing. I consider it a major breakthrough for early detection as the rate of people with cancer is frighteningly high with no signs of slowing down. I would like to see more younger people included in the trial they are the ones with their lives ahead of them have young families and all to frequent their cancers are far more aggressive

    I took part in this blood test trial in November last year and I am so pleased I did. I was unfortunately diagnosed with possible lung cancer and referred for further investigations which proved positive and at an early stage and now receiving treatment. I had no symptoms at the time of the test and must admit the outcome was initially a bit of a shock, but grateful that this trial has enabled treatment to be given at the early stages and hopefully will increase my chance of survival

  • Bill Randall
    5 November 2021

    I was interested in participation until I read the following in your article: “In a study involving people who had already been diagnosed with cancer, the test accurately detected cancer in 51.5% of people.”
    This is almost the same as chance, isn’t it? So tossing a coin and saying, “heads you’ve got cancer, tails you haven’t.” would give fairly similar results.
    Given that the subjects were already diagnosed with cancer, presumably one would expect fairly high concentrations of the relevant DNA fragments in their blood. So surely a far better detection rate than 1.5% above chance would be expected if the test really is sensitive and discriminates well.
    Or am I missing something?

    Katie Roberts

    Hi Bill,

    Thanks for your question. This figure is from this published study in the US. The 51.5% figure reported is the overall sensitivity of the test – the proportion of people who had a positive test result among all cancer participants tested (across all cancer types and clinical stages). The sensitivity of cfDNA analysis is limited by the amount of tumour DNA in the blood. Different cancers shed DNA into the bloodstream at different rates and the proportion of tumour-derived cfDNA in the blood tends to increase as cancer progresses. This means that the ability of this test to detect cancer varies by both cancer type and clinical stage, so it is better at picking up some cancers than others. Your comment highlights why further research is so important, and we eagerly await the findings of the NHS-Galleri screening trial, and the study exploring the use of the Galleri test in symptomatic populations.

    Best wishes,

    Freya, Cancer Research UK

    Please can you correct an error in this blog. Galleri HAS been tested on people who have not yet been diagnosed with cancer, contrary to your third and a subsequent paragraph. For example, the Pathfinder study of 6600 people in the US was entirely asymptomatic people; data was recently presented at ASCO on the interim results from this study.

    I would definitely take part. I think you are very lucky if you or your family have not been affected by Cancer it is more prevalent and affects people of all ages so any test that can help with early diagnosis is really important.

    I would be happy to get involved in this trial I am now past 70 and always aware of how cancer can develop without us knowing. Members of my family have been lost to this disease and so anything that will detect cancer early must be a good thing and save lives. For this reason I would always be willing to take part in a trial.

    In October 2013 I passed some blood and went to my GP. I had a blood test that suggested I had nothing to worry about. For the next few months I occasionally passed small amounts of blood until April when I passed a lot. Subsequent hospital investigations showed I had bowel cancer. Luckily it had not spread and surgery and chemotherapy dealt with it. If this test had been available then maybe my cancer would have been found sooner and I would not have risked it spreading. I consider myself extremely lucky that it did not spread as one of my neighbours wasn’t so lucky.

  • Marie

    This is such positive news. I lost both my parents to late diagnosis of cancer when they were in their seventies, then 3 years ago my daughter, aged 24 was diagnosed with cancer, a battle she is still bravely fighting. I would love to be considered for any trails to help this test to become available to all at the earliest opportunity. I turn 60 this summer.

  • Mark Davis

    I think this a great idea and I’m 48 and was 47 in 2021 when I was diagnosed with left top apex lung in in March 2021 and April 2021 the full top left lung was was removed fully. So I’m in remission at moment have my year scan in October 2022 to check cancer that it’s not in my lungs or anywhere else in my body. The blood test to find out is great as my cancer was found with me going for X ray and some other pain I was having. Scary but thankful it was early stage. I really hope I get the blood test one day. Keep up the good work.

    I always was so scared about cancer and after my
    Husband passed away I
    Just would do everything I can to help increase research in the area and also if possible discover if I have any kind of cancer and treat it in the early stages as my daughter can’t loose her mother as well.
    I really would like to be part of this trial.

  • Christine Graham

    This is an amazing development in the research you are doing. I consider it a major breakthrough for early detection as the rate of people with cancer is frighteningly high with no signs of slowing down. I would like to see more younger people included in the trial they are the ones with their lives ahead of them have young families and all to frequent their cancers are far more aggressive

    I took part in this blood test trial in November last year and I am so pleased I did. I was unfortunately diagnosed with possible lung cancer and referred for further investigations which proved positive and at an early stage and now receiving treatment. I had no symptoms at the time of the test and must admit the outcome was initially a bit of a shock, but grateful that this trial has enabled treatment to be given at the early stages and hopefully will increase my chance of survival

  • Bill Randall
    5 November 2021

    I was interested in participation until I read the following in your article: “In a study involving people who had already been diagnosed with cancer, the test accurately detected cancer in 51.5% of people.”
    This is almost the same as chance, isn’t it? So tossing a coin and saying, “heads you’ve got cancer, tails you haven’t.” would give fairly similar results.
    Given that the subjects were already diagnosed with cancer, presumably one would expect fairly high concentrations of the relevant DNA fragments in their blood. So surely a far better detection rate than 1.5% above chance would be expected if the test really is sensitive and discriminates well.
    Or am I missing something?

  • reply
    Katie Roberts
    10 November 2021

    Hi Bill,

    Thanks for your question. This figure is from this published study in the US. The 51.5% figure reported is the overall sensitivity of the test – the proportion of people who had a positive test result among all cancer participants tested (across all cancer types and clinical stages). The sensitivity of cfDNA analysis is limited by the amount of tumour DNA in the blood. Different cancers shed DNA into the bloodstream at different rates and the proportion of tumour-derived cfDNA in the blood tends to increase as cancer progresses. This means that the ability of this test to detect cancer varies by both cancer type and clinical stage, so it is better at picking up some cancers than others. Your comment highlights why further research is so important, and we eagerly await the findings of the NHS-Galleri screening trial, and the study exploring the use of the Galleri test in symptomatic populations.

    Best wishes,

    Freya, Cancer Research UK

  • Harpal Kumar

    Please can you correct an error in this blog. Galleri HAS been tested on people who have not yet been diagnosed with cancer, contrary to your third and a subsequent paragraph. For example, the Pathfinder study of 6600 people in the US was entirely asymptomatic people; data was recently presented at ASCO on the interim results from this study.

    I hope there will be in-depth interviews with the people in whom cancer is diagnosed and with each and every member of their family about how their life has changed having had that diagnosis.
    A short study like this does not seem adequate to understand the unintended harms.
