Abstract
Introduction Up to 14% of upper gastrointestinal cancer (UGIC) subjects had an OGD that did not diagnose cancer up to 3 years prior to diagnosis. The rate of and associated risk factors for post-OGD upper gastrointestinal cancer (POUGIC) in the West Midlands were examined. Methods Computerised OGD records from 8 NHS trusts in the West Midlands between 1998 and 2010 were retrieved and submitted to the West Midlands Cancer Intelligence Unit (WMCIU) for UGIC registrations linkage. Subjects undergoing OGD 3 to 36 months before diagnosis were identified as POUGIC and subjects with no OGD 3 to 36 months prior to diagnosis served as controls. The influence of age, gender, indication, endoscopist specialty, trainee involvement, sedation, number of biopsies taken from focal abnormalities, site and histology of UGIC on POUGIC were examined by logistic regression analysis. Results 115,113 OGD records were submitted to WMCIU and 3870 UGIC were linked. After exclusions, 2909 UGIC subjects were analysed. There were 275 (9.5%) POUGIC subjects (154 oesophageal cancer (OC) and 121 gastric cancer (GC)). The POUGIC rate ranged from 7.6 to 11.8% between the trusts. Of the POUGIC subjects, 143 (52.0%) had OGD 3 to 12 months and 132 (48.0%) 12 to 36 months prior to UGIC diagnosis. POUGIC subjects were younger (69.6±11.7 yrs) compared with controls (72.0±11.6 yrs) (p = 0.001). There were no association between POUGIC and OC or GC (GC OR 1.15, 95%CI 0.89–1.48, p = 0.289) or subject gender (female 1.14, 0.88–1.48, p = 0.312). Subjects with alarm symptoms (0.33, 0.26–0.43, p Conclusion The POUGIC rate in the West Midlands was 9.5% between 1998 and 2010 and varied between 7.6 and 11.8% between trusts. POUGIC was associated with younger age, a lack of alarm symptoms and less biopsies from abnormalities. There was no significant survival difference between POUGIC subjects and controls at 1 yr.
