Over the coming weeks, thousands of participants in south east London who enrolled on the NHS-Galleri trial in 2021 will be returning to nearby mobile clinics, starting in Sydenham, for their last of three appointments for the trial.

Participants will be asked to give a blood sample to help the NHS see if using the Galleri® blood test alongside existing cancer screening can help detect cancer early. Finding cancer early often means it is easier to treat.

Since the NHS-Galleri trial first arrived in south east London in September 2021 the trial has successfully enrolled over 140,000 volunteers from different ethnic backgrounds across England, including 9,000 from south east London.

Volunteers were all aged 50 to 77 years old at the point of enrolling onto the trial and had not been diagnosed or treated for cancer in the last three years. Participants can book their appointment online or calling the freephone 0800 030 9245

Throughout this Autumn and Winter, participants can book their appointment at one of the following locations: 

  • Sainsbury’s on Southend Lane, Sydenham, SE26 4PU ​​​​​​ - 18th September – 2nd October  (excludes weekends)
  • Bromley North Station on Northside Road, BR1 3NN - 5th October – 25th October (excludes weekends)
  • Asda on Old Kent Road, Southwark, SEL 5AG - 27th November - 14th December (excludes weekends)

Smitha Nathan, Associate Director at the South East London Cancer Alliance, said: “We are delighted to be welcoming back volunteers to south east London for their last trial appointments. Even if you missed your appointment last year, your involvement this year will still help with this research.”

Visiting the trial clinic in Sydenham on Wednesday 20th September, Ellie Reeves MP for Lewisham West and Penge said: “This area should be proud of having thousands of people volunteering for this important clinical trial which could help the NHS to find more cancers at an early stage when they are often easier to treat. I am proud that Sydenham is an ethnically and socially diverse part of London and it’s important that trials like this represent all  who may benefit from advances in cancer screening in future.”

An NHS spokesperson said: “We are truly grateful for the ongoing support of volunteers in south east London. This trial continues to put the NHS at the forefront of cutting-edge research and technology. If this trial is a success, the Galleri blood test could play a major part in achieving the NHS Long Term Plan ambition to diagnose three quarters of cancers at an early stage when it is easier to treat.”

If early trial results are promising, the NHS may decide to pilot the delivery of the test to a further 1 million people. Early research has shown that the Galleri test could help to detect cancers that are typically difficult to identify early – such as head and neck, bowel, lung, pancreatic, and throat cancers.

The test works by analysing chemical patterns in fragments of DNA that are shed from tumours into the bloodstream.

The NHS-Galleri trial is being run by The Cancer Research UK and King’s College London Cancer Prevention Trials Unit in partnership with the NHS and healthcare company, GRAIL, which has developed the Galleri test.

The trial is operating with the support of eight NHS Cancer Alliances across England that span Cheshire and Merseyside, Greater Manchester, the North East and North Cumbria, West Midlands, East Midlands, East of England, Kent and Medway, and South East London.
