Introduction/Background The NHS England ovarian cancer audit feasibility pilot in 2018 suggested a geographical variation of treatment of ovarian cancer in England. There are areas of significant social deprivation in Northern Ireland (NI) and the aims of this project was to determine if there was any association between deprivation and treatment of ovarian cancer in NI.

Methodology All patients diagnosed with epithelial ovarian cancer between 2014 and 2017 were included, those with borderline tumours in the same timeframe were excluded. Data was collected electronically for all patients and their treatment types, if any. Postcodes were obtained for all patients and a Northern Ireland Statistics and Research Agency (NISRA) deprivation index was calculated and patients were ranked into deprivation quintiles (1 = least deprived, 5 = most deprived) . This was correlated to the treatment that each patient received (specifically active cancer treatment vs no treatment and surgical vs non-surgical treatment) to assess if any correlation was identified.

Results 603 patients were identified. 101 patients in deprivation quintile-1 (83% active treatment, 75% surgery), 132 patients in deprivation quintile-2 (83% active treatment, 56% surgery), 129 patients in deprivation quintile-3 (89% active treatment, 54% surgery), 108 patients in deprivation quintile-4 (88% active treatment, 69% surgery), 133 patients in deprivation quintile-5 (91% active treatment, 64% surgery). No statistically significant correlation was found between social deprivation status and treatment modality.

Conclusion There is no correlation between social deprivation status and treatment of ovarian cancer in NI.
