Study information
Scientific title
Pathology-guided treatment of rectal cancer: a randomised controlled trial
Acronym
Study hypothesis
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)?
