Circulating Tumour DNA (ctDNA) in Patients With Colorectal Cancer and the Relationship to Imaging Features of Extramural Venous Invasion (ctDNA)

October 16, 2024 updated by: Imperial College London
This study does not involve randomization or treatment. Eligible patients have colorectal adenocarcinoma with no metastases eligible for curative surgery. A pre operative staging scan must have been completed within 6 weeks prior to surgery. Two x 20ml blood samples will be taken from each patient, one prior to and one during or within 24hrs after surgery. Patients are annually followed up to 3 years.

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
mrEMVI positive rectal tumours
Patients will be registered whose rectal tumours are mrEMVI positive (i.e. EMVI is present in baseline and post-chemoradiotherapy MRI scans).
Other: Blood sample (mrEMVI positive patient)
Two blood samples are taken from each patient with mrEMVI positive tumours post chemoradiotherapy. One pre-surgery and one during surgery from a peripheral vein.
mrEMVI negative rectal tumours
Patients registered who were mrEMVI positive at baseline MRI but have become mrEMVI negative post-chemoradiotherapy.
Other: Blood sample (mrEMVI negative patient)
Other Names:
  • Two blood samples are taken from each patient with mrEMVI negative tumours post chemoradiotherapy. One pre-surgery and one during surgery from a peripheral vein.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
To determine if there is a link between EMVI status and ctDNA
Time Frame: Up to 2 years
Proportion of patients who are EMVI positive demonstrating higher % mutation frequency of circulating cell-free and tumour specific DNA compared with patients who are EMVI negative.
Up to 2 years

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
To investigate whether ctDNA levels change during surgery according to EMVI status
Time Frame: Up to 2 years
Measure the intraoperative % mutation frequency of ctDNA in EMVI positive compared with EMVI negative patients
Up to 2 years
To investigate the effect of ctDNA status on patient survival outcomes
Time Frame: At 1, 2 and 3 years
Record survival outcomes of patients who are: EMVI negative with low ctDNA levels, EMVI negative with high ctDNA levels, EMVI positive with low ctDNA levels, EMVI positive with high ctDNA levels
At 1, 2 and 3 years
