Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Patients will complete chemoradiation and then based on response (complete response or other) they will be allocated to one of the two study cohorts; follow up with MRI scans (complete responders -considered the intervention arm) or surgery (other).
The surgery is considered the standard arm.
For patients whom are complete responders and go onto the MRI arm, they will not receive surgery. Instead they will be followed up with clinical assessments and sigmoidoscopy, 3-monthly for the first two years, then 6-monthly in years 3-5; CT scans at 6, 12, 24, 36, 48 and 60 months; MRI and blood tests every 3 months in the first year then 6-monthly in years 2-5.

Comparator / control treatment
Patients will complete chemoradiation and then based on response (complete response or other) they will be allocated to one of the two study cohorts; follow up with MRI scans (complete responders) or surgery (other). Surgery is the control and the standard pathway for patients.

Outcomes
Primary outcome [1] 318804 0
Determine the efficacy of the ‘Watch and Wait’ strategy, by measuring the following endpoints: a. Co-Primary endpoint-1: The ‘three-year local failure rate’ (in the ‘Watch and Wait’ arm) defined as local recurrence that cannot be resected with clear margins - determined by patients through MRI, CT scan and surgical review.
Timepoint [1] 318804 0
This will be assessed at three years after commencing therapy using the Sigmoidoscopy, CT scan and MRI & blood tests.

b. Co-Primary endpoint-2: The rate of rectal preservation (in the ‘Watch and Wait’ arm) measured by number of patients not requiring surgery
Timepoint [2] 318969 0
Three years after commencing therapy.
Secondary outcome [1] 366102 0
1. Determine the safety of the ‘Watch & Wait’ strategy by measuring the following endpoint (in the watch and wait arm): (composite) a. The ‘three-year local recurrence rate’ b. The ‘three-year distant metastasis rate’ c. The overall survival d. The ‘incurable disease-free survival rate’ (recurrent cancer that cannot be surgically excised with the intention of achieving a cure) .These will be assessed through the use of MRI's, CT scans, sigmoidoscopy and clinical examinations.
Timepoint [1] 366102 0

Secondary outcome [2] 366104 0
To investigate Patient reported Outcome Measures -Quality of Life

Quality of Life is defined as the general well-being of the individual; this outcome is measured using the EORTC QLQ-C30 questionnaire which is a validated questionnaire developed to assess the quality of life of cancer patients. The EORTC QLQ-CR-29 will also be used; this is a validated questionnaire developed to assess the quality of life of patients with a history of colorectal cancer and is used in addition to the EORTC QLQ-C30 questionnaire.
Timepoint [2] 366104 0
Completed by all patients at screening, at 8-10 weeks post chemoradiotherapy (or 18-20 weeks post chemoradiotherapy if receiving Total Neoadjuvant Therapy), then yearly for 5years post chemoradiotherapy.
Secondary outcome [3] 366873 0
To investigate Patient reported Outcome Measures - Health Related Quality of Life.

Health-related quality of life is a multi-dimensional concept that includes domains related to physical, mental, emotional and social functioning. This outcome will be measured using a validated questionnaire: the EQ-5D-5L questionnaire
Timepoint [3] 366873 0
Completed by all patients at screening, at 8-10 weeks post chemoradiotherapy (or 18-20 weeks post chemoradiotherapy if receiving Total Neoadjuvant Therapy), then yearly for 5years post chemoradiotherapy.

To investigate Patient reported Outcome Measures - Fear of Cancer Recurrence

Fear of Cancer Recurrence (FCR) defined as feeling anxious about the cancer coming back and is measured by Fear of Cancer Recurrence Inventory (FCRI SF). To interpret the FCR results and to measure response efficacy we will use a modified Response Efficacy Scale specifically designed for this study.
Timepoint [4] 366874 0
Patients will complete the Fear of Cancer Recurrence Inventory and The Response efficacy questionnaire yearly for 5years post chemoradiotherapy.
Secondary outcome [5] 366875 0

Secondary outcome [6] 366876 0
To investigate Patient reported Outcome Measures - Bowel Related Quality of Life.

This outcome encompasses multiple aspects of bowel function and will be measured using the MSKCC Bowel Function Questionnaire and LARS score.
Timepoint [6] 366876 0
All patients will complete the MSKCC and LARS questionnaires at screening and at 8-10 weeks post chemoradiotherapy (or 18-20 weeks post chemoradiotherapy if receiving Total Neoadjuvant Therapy). Those patients who do not have a stoma, will also complete those questionnaires yearly for 5years post chemoradiotherapy.

Summary
Brief summary
The purpose of this study is to determine the effectiveness of a ‘wait and watch’ strategy in patients with rectal cancer who have completed chemoradiotherapy.

Who is it for?
You may be eligible for this study if you are an adult who has been diagnosed with advanced rectal cancer and will be undergoing chemoradiotherapy.

Study details
After chemoradiotherapy you will be reviewed for any evidence of cancer, through physical exams, imaging and sigmoidoscopy. If there is evidence of cancer you will have surgery to remove this cancer. If there is no evidence of cancer you will not have surgery but instead be followed up at set time points over 5 years, having further imaging, physical exams blood tests and sigmoidoscopies.

it is hoped that this research will provide support for the pathway of not conducting surgery on patients who have no evidence of cancer after their chemoradiotherapy.
