Study design	Randomised controlled trial
Secondary study design	Randomised controlled trial
Scientific title	Pathology-guided treatment of rectal cancer: a randomised controlled trial
Study objectives	In inoperable rectal cancer: are local recurrence-free survival rates and quality of life optimised by giving all patients short course pre-operative radiotherapy, or is it a preferable option to give post-operative chemoradiotherapy only to those at high risk of recurrence (i.e. with involved margins following surgery)?
Ethics approval(s)	Not provided at time of registration
Health condition(s) or problem(s) studied	Rectal cancer
Intervention	1. One group receives a short course pre-operative radiotherapy followed by surgery 2. The other group receives surgery followed by postoperative chemo-radiotherapy
Intervention type	Other
Primary outcome measure(s)	Local recurrence (as defined using an algorithm designed for the trial).
Key secondary outcome measure(s)	1. Local recurrence-free survival 2. Overall survival 3. Time to appearance of distant metastases 4. Disease-free survival 5. Morbidity 6. Quality of life 7. Economic implications
