The prognosis for oesophageal cancer is poor with a median survival of 3-5 months and recurrences are frequent. The best chance of cure is successful surgery and pre-operative chemoradiotherapy is used to try and improve outcomes. However, patients may either not respond or may progress during therapy and it is important to differentiate the responders from non-responders. Clinical parameters such as weight gain and improvement in swallowing can be assessed but imaging is used in an attempt to improve outcomes.
