A Comparison of Emergency First Presentations of Colorectal Cancer in Under–50 and Over–50 Year-Old Patients

AbstractIntroduction: Colorectal cancer (CRC) is the second commonest malignancy related death in Western Europe with incidence increasing in young adults. 31% of UK patients with CRC present as emergencies. We compare the incidence, characteristics, management and outcomes in two cohorts presenting as CRC emergencies; under-50 and over-50 years old. Materials and Methods: Retrospective analysis was performed on 322 patients with emergency presentations of CRC over a 9-year period (January 2005–December 2013, West Suffolk Hospital, UK). Data were analyzed for demographics, symptoms, investigations, stage, grade, genetics, tumor location, management, and mortality. Results: 300 patients over 50 years old presented with CRC emergencies; 153 women (51%):147 men (49%); median age 77 years (interquartile range: 67–84). 22 patients under 50-years-old; 12 women (55%):10 men (45%); median age 43 years ([Interquartile Range (IQR)]: 35–46 years). Bowel obstruction was less common in under-50s (18.2% vs. 40.7%; p = ...
