title: Peri-operative radiotherapy for rectal cancer: the case for a selective pre-operative approach - the third way.
abstract: Peri-operative radiotherapy has been used widely in addition to surgery in an attempt to reduce local recurrence (LR) following surgical resection of rectal cancer. Currently different groups follow different approaches with some routinely administering one weeks pre-operative radiotherapy to all cases of operable mobile cancer with others favouring postoperative chemoradiotherapy for selected high risk groups. In this review we bring together the changes in surgery, pathology and imaging that have occurred in recent years and together with the data from recent randomized pre-operative radiotherapy trials propose a logical and optimal way of managing rectal cancer. This third way is selective and pre-operative and should ensure a low rate of LR with radiotherapy reserved for those cases that need it.
