Brief Summary
This is a retrospective study using images acquired routinely for diagnosis of rectal cancer to see if these could be used to predict responses to radiotherapy treatment and if it can, whether the treatment can be optimised to produce better outcome for patients. Using a clinical database, patients who have had neo-adjuvant chemo-radiotherapy will be recruited, their diagnostic images and radiotherapy planning scan will be obtained. By use of imaging registration and clinical information, the question of why some patients respond well to radiotherapy and some don't could be answered.

Interventions
The study will not have a direct intervention. It will recruit patients who have had chemo-radiation as part of their standard of care treatment for rectal cancer.
Eligibility Criteria

- Histologically confirmed rectal adenocarcinoma.
- Received pelvic radiotherapy (+/- chemotherapy) as neo-adjuvant treatment
- Age 18 and above
You may not qualify if:
