Recurrence after attempted curative colorectal cancer surgery remains problematic with up to 50% developing metastases by 5 years.1 More aggressive surgical approaches likely improve prognosis,2 and there is a reasonable assumption that early detection by intensive patient follow-up improves outcomes. Two meta-analysis suggest regular measurement of carcinoembryonic antigen (CEA) and CT scanning of the chest, abdomen and pelvis (CT CAP) may increase the number of patients with potentially curable recurrence.3 ,4 The aim of this trial was to provide evidence for the benefit or otherwise …
