About this trial

The goal of this observational study is to evaluate if a blood test for circulating progastrin (hPG80) and transposable elements (TEs) can accurately predict colorectal cancer (CRC) or polyps in adult patients referred to the 2-week wait (2WW) or Straight to Test (STT) pathways for suspected lower gastrointestinal cancer.

The main questions it aims to answer are:

Can plasma hPG80 levels accurately predict a diagnosis of CRC or polyps in patients undergoing standard 2WW investigations? Can transposable elements (TEs) in the plasma serve as predictive biomarkers for CRC diagnosis in these patients? What are the patient preferences for different diagnostic tests for CRC, particularly a blood-based test compared to more invasive methods?

Participants will:

Provide a 20ml blood sample during a routine hospital visit for their 2WW diagnostic test (e.g., colonoscopy, CT Colon).

Undergo standard clinical investigations as determined by their treating clinicians.

Have their final diagnosis (cancer, polyp, or normal) correlated with their plasma hPG80 levels.

For a subset of 100 participants (25 with confirmed CRC, 75 non-cancer), have their plasma analyzed for circulating signatures using RNAseq and DNAseq.

Complete an electronic post-study questionnaire to explore their preferences and experiences with different CRC diagnostic tests used within the 2WW pathway.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Adult, lower GI 2WW and or Straight to Test (STT) referral patients with suspected lower GI cancer.

Male and Female patients aged >18 years.

2WW referral patients with no history of inflammatory bowel disease.

Performance status (ECOG 0-2; and 3 pending clinical assessment of fitness).

Disqualifiers

Any patients referred outside of the 2WW and or STT referral pathways with suspected Lower GI cancer or those referred as an emergency with or suspected CRC.

Age < 18 years.

Patients not fit for standard investigations (e.g. not fit for gastroscopy, colonoscopy or CT colonography) in the 2WW pathway.

Patients with no capacity to consent or who declined consent for participation.

Trial population

All adult patients who are referred by the GPs to the Barts Health NHS trust under the 2WW referral pathway and the STT pathway would be potentially eligible. We are planning to recruit patients initially only from the Royal London Hospital site and there is potential to expand recruitment to other hospital sites of Barts Health NHS Trust, if necessary.
