Pathological Complete Response (PCR)
time frame: The pCR rate will be assessed after surgery, therefore approximately 24 weeks after randomisation.
RECIST Response Rate
time frame: This will be assessed after chemotherapy has ended. Chemotherapy will be given for up to 12 weeks.
CRM Negative Resection Rate
time frame: This will be assessed after surgery, therefore approximately 24 weeks after randomisation.
T and N stage downstaging
time frame: This will be assessed at the completion of treatment. Treatment will be given for up to 12 weeks.
Progression Free Survival
time frame: This will be assessed pre-cycle 4 and post-treatment, therefore at 6 weeks and 12 weeks after randomisation.
Disease Free Survival
time frame: This will be length of time from date of surgery till relapse, second colorectal primary or death from any cause, whichever occurs first. These occurrences will be reported on CRFs every six months for up to three years.
time frame: From study entry until death, until 3 years after randomisation.
time frame: From date of surgery until local failure, until 3 years after randomisation.
1 year Colostomy Rate
time frame: Post surgery (approximately 24 weeks after randomisation) and 1 year after randomisation.
Frequency and severity of Adverse Events
time frame: This will be from date of randomisation until 30 days after completion of treatment. Treatment is given for up to 12 weeks.
Compliance of Chemotherapy
time frame: This will be at the end of treatment (up to 12 weeks)
Tumour Regression Grade (TRG)
time frame: Assessed after surgery, approximately 24 weeks after randomisation.
Tumour Cell Density
time frame: This will be assessed after surgery, approximately 24 weeks after randomisation.
Male or female participants from 18 years up to 75 years old.

|Official title||A Phase II, Multicentre, Open-Label, Randomised Study of Neoadjuvant Chemotherapy and Bevacizumab in Patients With MRI Defined High-Risk Cancer of the Rectum|
|Principal investigator||Rob Glynne-Jones, BA MB FRCP FRCR|
|Description||The purpose of this study is to look at two different combinations of anticancer drugs to see how effective they are at shrinking your cancer and preventing it from coming back after surgery. Patients with locally advanced rectal cancer are sometimes treated with radiotherapy, with or without chemotherapy, before having surgery. Radiotherapy treats only the main tumour in the rectum. This means that if tiny deposits of cancer have spread to other parts of the body (metastases), these could continue to grow. Giving chemotherapy and radiotherapy together (chemoradiotherapy) can treat both the main tumour and any spread. However, due to the side-effects we can't give as much chemotherapy in combination with radiotherapy than if chemotherapy were given on its own and treatment of possible metastases may not be as good as it could be. If the risk of the main tumour coming back is quite small, then giving treatment that targets metastases should be the best option. This study looks at two well known combinations of chemotherapy drugs: FOLFOX (folinic acid, 5-fluorouracil, oxaliplatin) and FOLFOXIRI (folinic acid, 5-fluorouracil, oxaliplatin, irinotecan). Chemotherapy works by killing cancer cells. In addition, the anticancer drug bevacizumab will be given with both the FOLFOX and FOLFOXIRI. Bevacizumab is an "anti-angiogenesis" drug. It works by stopping tumours from making new blood vessels. Without new blood vessels, the cancer cells do not get the food and oxygen they need to survive and grow. Attacking the cancer in these ways may be more effective than chemotherapy alone.|
