87 The Relationship Between the Locality-Specific Incidence of Emergency and Late-Stage Presentation of Oesophagogastric Cancer and Socioeconomic Deprivation in the Stockport Region

Abstract Aim Emergency and late-stage presentation contribute to poor outcomes in Oesophagogastric (OG) cancer. Socioeconomic deprivation has also been linked to adverse outcomes. This study investigates the relationship between the locality-level deprivation indices and incidence of emergency and late-stage presentation of OG cancer region in the Stockport region. Method 221 individuals were diagnosed with OG cancer between January 2022 and December 2024. UK census data were interrogated to identify the incidence of emergency and stage 4 OG cancer presentation at the Lower-Layer Super Output Area (LSOA) level (population units of 1000-3000) and correlated with the LSOA Index of Multiple Deprivation (IMD). Results No significant correlation was found between deprivation (IMD Rank/Decile) and LSOA incidence for stage 4 or emergency presentation. For stage 4 incidence rates, Pearson’s r = -0.15 (p = 0.395), Spearman’s ρ = -0.05 (p = 0.795); for emergency rates, r = -0.16 (p = 0.465), ρ = -0.04 (p = 0.861). Incidence ratios (IR) showed similarly weak associations. However, descriptive trends indicated higher than average emergency incidence rates in the most deprived areas and a general decline in stage 4 incidence from moderately to least deprived areas. Several LSOAs had elevated IR >2 SD above the mean (IR = 1.035), reaching 3.18 for stage 4 and 2.86 for emergency presentations. Conclusions IMD is not significantly related to higher local incidences of emergency or late-stage OG cancer. However, utilising this methodology identified localities with significantly higher incidences, which can allow for targeted locality-specific health interventions and campaigns to improve outcomes.
