## TL;DR

An emergency presentation means a cancer was diagnosed after the person arrived as an emergency, through A&E or an urgent admission, rather than through a GP referral or screening. It is the route with the worst survival because the cancer is usually advanced by then. Almost half of pancreatic cancers in England are diagnosed this way, more than for almost any other common cancer.

## Summary

England's Routes to Diagnosis work links hospital episode statistics, cancer waiting times, screening and registration data to assign every registered cancer to one of eight routes (screening, urgent suspected cancer referral, other GP referral, outpatient, inpatient elective, emergency presentation, death certificate only, unknown); the proportion by route differs sharply between cancers, and patients diagnosed through the emergency route have substantially lower one-year relative survival (Elliss-Brookes 2012). For pancreatic cancer in England in 2019, 22 percent of cases were diagnosed through an urgent suspected cancer (two week wait) referral and 45 percent through an emergency presentation (Cancer Research UK), against 4 percent emergency for breast cancer on the same source; the emergency share is highest for cancers whose early symptoms are vague or absent. A 2026 study built a digital measure of emergency presentation in the US Veterans Affairs system (positive predictive value 86.4 percent): 60.9 percent of 4,415 pancreatic cancer patients presented as emergencies, with 1.38 times the adjusted odds of advanced stage and 1.64 times the mortality, and nearly one in five emergency cases had a missed opportunity for earlier diagnosis on record review (Br J Cancer 2026). The SYMPTOM pancreatic study explains part of the problem: among 391 people referred with suspected pancreatic cancer, no first symptom distinguished the 30 percent who had cancer from those who did not, and only later symptoms such as jaundice did (Walter 2016). Reducing emergency presentation is an aim of the NHS Long Term Plan target for early-stage diagnosis; the levers are the NG12 referral rules, direct-access CT for GPs, awareness of new-onset diabetes and weight loss as signals, and rapid diagnostic centres for non-specific symptoms. The figure is worth knowing when reading survival statistics: a cancer with a 45 percent emergency share has its averages pulled down by the route as much as by the biology.
