This study involves the collection and analysis of tumour tissue, serial blood samples and clinical data in patients with newly diagnosed stage II and III colorectal cancer (CRC). The study is planned to recruit patients from sites within (but not limited to) the London Cancer Alliance over 3 years.
DNA fragments containing cancer specific markers or mutations that originate from tumour can be detected in blood. This is known as circulating cell free tumour DNA (ctDNA). In patients that have undergone potentially curative surgery, blood samples to detect and quantify ctDNA is a promising strategy for the identification of minimal residual disease(very small amounts of persisting disease) and may identify disease relapse earlier than existing methods.
Part A is a feasibility study where the proportion of patients with detectable ctDNA in blood prior to surgery will be determined. Part B will assess whether detection of ctDNA in a blood sample taken 4-8 weeks after surgery, can be used to predict relapse. Levels of ctDNA at other time points such as: during chemotherapy and post-chemotherapy and the association between the level of ctDNA with disease free survival (the length of time from the removal of cancer until the cancer returns in patients that have a relapse) and overall survival will be determined.
Some patients are offered chemotherapy after surgery (adjuvant chemotherapy) to reduce the risk of the cancer returning. Only a proportion of patients will benefit directly from this and it is not entirely clear which patients these will be, although there are specific risk features that are currently used to guide treatment decisions. The study may identify a subset of patients that are unlikely to benefit from adjuvant chemotherapy on the basis of ctDNA analysis and could therefore safely spare some patients from receiving chemotherapy and its associated side-effects.

Exclusion criteria to be used prior to registration: -Scheduled to have neoadjuvant chemotherapy, (neoadjuvant chemoradiotherapy for patients with rectal cancer is permitted) -Current or previous other malignancy within 5 years of study entry, except cured basal or squamous cell skin cancer, superficial bladder cancer, prostate intraepithelial neoplasm, carcinoma in situ of the cervix or other non-invasive malignancy. Additional exclusion criteria for rectal cancer patients following completion of pre-operative radiotherapy or chemoradiotherapy -Patients scheduled to have further pre-operative treatment with chemotherapy -Patients that are no longer proceeding with surgery i.e. those in whom surgery is considered too high risk -Patients that are no longer proceeding with surgery as they are proceeding with a deferral of surgery approach (NB these patients will remain in the study as an exploratory cohort and will therefore continue to have bloods taken) Exclusion criteria at the first post-operative visit: -Stage I patients based on the post-operative histopathology report should be excluded, apart from rectal patients that had undergone pre-operative chemoradiotherapy for whom their pre-chemoradiotherapy MRI staging should be used. -Scheduled to receive post-operative radiotherapy
