- Abstract
Objectives: To identify opportunities for reducing emergency colon cancer diagnoses, we evaluated symptoms and benign diagnoses recorded before emergency presentations (EP). Methods: Cohort of 5,745 colon cancers diagnosed in England 2005–2010, with individually linked cancer registry and primary care data for the 5‐year pre‐diagnostic period. Results: Colon cancer was diagnosed following EP in 34% of women and 30% of men. Among emergency presenters, 20% of women and 15% of men (p = 0.002) had alarm symptoms (anaemia/rectal bleeding/change in bowel habit) 2–12 months pre‐diagnosis. Women with abdominal symptoms (change in bowel habit/constipation/diarrhoea) received a benign diagnosis (irritable bowel syndrome (IBS)/diverticular disease) more frequently than men in the year before EP: 12% vs. 6% among women and men (p = 0.002). EP was more likely in women (OR = 1.20; 95% CI 1.1–1.4), independently of socio‐demographic factors and symptoms. Benign diagnoses in the pre‐diagnostic year (OR = 2.01; 95% CI 1.2–3.3) and anaemia 2–5 years pre‐diagnosis (OR = 1.91; 95% CI 1.2–3.0) increased the risk of EP in women but not men. The risk was particularly high for women aged 40–59 with a recent benign diagnosis vs. none (OR = 4.41; 95% CI 1.3–14.9). Conclusions: Women have an increased risk of EP, in part due to less specific symptoms and their more frequent attribution to benign diagnoses. For women aged 40–59 years with new‐onset IBS/diverticular disease innovative diagnostic strategies are needed, which might include use of quantitative faecal haemoglobin testing (FIT) or other colorectal cancer investigations. One‐fifth of women had alarm symptoms before EP, offering opportunities for earlier diagnosis.
