  "abstract": "Introduction and objectives The 2023 National lung cancer audit highlighted that 31% of patients were diagnosed during an emergency admission and 43% of all lung cancer diagnoses were of stage IV disease, with associated poorer outcomes. Our aim was to better understand these presentations.Methods We retrospectively reviewed emergency lung cancer presentations between April 2022 and December 2024 across the three acute hospitals in Dorset. We utilised the Dorset Intelligence Insight System to review population demographics within this cohort and for all stage IV lung cancer diagnoses between 2022 and 2024.Results Of 410 patients diagnosed via an emergency presentation, 181/410(44%) were female, the median[IQR] age was 76[69–83] years and WHO performance status ≤2 in 237/410(58%). Histological diagnosis was achieved in 223/410(54%), with non-small cell lung cancer (NSCLC) accounting for 172/223(77%). Of those with NSCLC, 147/172(85%) had stage III-IV disease. 130/187(70%) of those with only a radiological diagnosis had stage III-IV disease. 40/410(10%) were offered treatment with curative intent, 222/410(54%) best supportive care. 320/410(78%) patients had died at the point of data collection.At presentation, respiratory symptoms were reported by 248/410(60%) and 277/410(68%) had attended the emergency department at least once within 6 months of diagnosis. Only 102/410(25%) were eligible for lung cancer screening.Only 9% of the Dorset population fall into the 20% most deprived nationally, based on index of multiple deprivation. Of the emergency presentations, all were from a primary care network with ≤2% of patients in the most deprived 20% of the population nationally. Across Dorset, 552 patients presented with stage IV disease between 2022 and 2024. There was no significant difference between percentage of stage IV diagnoses between the most and least deprived quintiles within Dorset at 51/85(60%) and 92/153(60%) respectively (graph one).Abstract P173 Figure 1Conclusions Our data confirms that emergency lung cancer presentations often present with advanced disease and only 10% of patients were offered treatment with curative intent. Lung cancer screening aims to identify early stage, treatable disease, but only 25% of this cohort were eligible. Across Dorset, degree of deprivation did not affect the proportion of patients presenting with late-stage disease.",
