Trial summary

This study will determine the effect of the use of circulating tumour DNA (ctDNA) to guide adjuvant chemotherapy on recurrence-free survival in stage II colon or rectal cancer patients

Who is it for?
You may be eligible to join this study if you are aged 18 years or above, and have been diagnosed with Stage II colon or rectal cancer and have had your cancer curatively resected. 

Study details
Participants in this study are randomly allocated (by chance) to one of two groups. Participants in one group will have blood samples taken and analysed for circulating tumour DNA (ctDNA) and be treated according to the ctDNA results. Those with positive ctDNA results will receive standard 5FU-based adjuvant chemotherapy (either single agent or combined with oxaliplatin), while those with negative ctDNA will not receive adjuvant chemotherapy. 
Participants in the other group will have a blood sample taken, but the ctDNA result will not be disclosed. Patients in this group will be treated according to standard clinical criteria at the discretion of the treating physician.
Participants who had positive ctDNA results and are being treated with adjuvant chemotherapy will have monthly blood samples taken during treatment to track ctDNA levels. 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.


Key inclusion criteria

1. Subjects with curatively resected stage II (T3-4, N0M0) colon or rectal cancer.
2. Patients with rectal cancer will be eligible unless they have had pre-operative combined chemotherapy or radiotherapy, or are scheduled for post-operative combined chemotherapy and radiotherapy. All rectal cancer patients included in the trial must have had TME type surgery with negative (R0) resection margins.
3. A representative paraffin embedded tumour sample is avaiable for molecular testing.
4. Fit for adjuvant chemotherapy.
5. ECOG performance status 0-2.
6. Patients that are accessible for follow up.
7. CT C/A/P within 8 weeks demonstrating no metastatic disease.

Minimum age18 Years

GenderBoth males and females

Can Healthy volunteers participate? No

Key exclusion criteria

1. History of another primary cancer within the last 3 years, with the exception of non-melanomatous skin cancer and carcinoma in situ of the cervix.
2. Patients with multiple primary colorectal cancers
3. Patients treated with neoadjuvant chemo-radiation.
4. Medical or psychiatric condition or occupational responsibilities that may preclude compliance with the protocol.
