Trial summary

The primary purpose of this study is to show that by using ctDNA results, in addition to assessing the risk of tumour recurrence by standard pathology assessments, the number of patients receiving adjuvant (post surgery) chemotherapy will be reduced.
Who is it for?
You may be eligible to join this study if you are aged 18 or over, and have received chemo-radiation followed by surgery for locally advanced rectal cancer.
Study details:
All patients enrolled in this study are randomly allocated (by chance) to one of two groups; Standard of care (SOC) group or the ctDNA-informed group.  The decision to proceed with chemotherapy for those in the SOC group is based only on the standard risk assessment of the tumour (how likely your tumour is to come back or recur). Their ctDNA result will not be disclosed.  Those who are randomised to the ctDNA-informed group will be treated with chemotherapy if they are ctDNA positive OR if they are ctDNA negative AND are considered to have a tumour at high risk of recurring based on the standard risk assessment.  Only those in the ctDNA-informed group who have chemotherapy will have monthly ctDNA samples collected; up to four samples collected over 4 months then a final sample after chemotherapy has finished.
All participants will be followed up 3 monthly for 2 years, then 6 monthly for 3 years through their hospital for a total of five years for disease recurrence and survival.
It is hoped that the findings from this study will demonstrate that using ctDNA results to help make a decision as to who receives adjuvant chemotherapy will result in a reduction in the number of patients having chemotherapy and doing so, without compromising the rate of disease recurrence when compared to standard of care.
