The impact of COVID19 on the diagnostic and treatment pathways for patients with endometrial cancer in Northern Ireland

Introduction/BackgroundCOVID-19 has significantly impacted all areas of medicine including access to primary care. The majority of women with endometrial cancer present in early stages and have promising survival outcomes. The concern is that COVID-19 has caused potential delays in diagnosis leading to patients requiring more extensive surgical management and affecting disease outcomes.MethodologyAll patients diagnosed with endometrial cancer in 2019 (pre COVID-19), 2020 (during peak of COVID-19) and 2021 (during COVID-19 recovery) were included. Patients with myometrial sarcoma, other myometrial tumours and endometrial cancer recurrences were excluded. Data was collected electronically including histology, FIGO stage at diagnosis, symptom duration, parity, BMI, surgical location (regional cancer centre vs cancer unit), surgical approach and type, complications, adjuvant treatment and survival status. Statistical analysis was then performed.Results639 were patients identified in total (194 in 2019, 216 in 2020 and 229 in 2021). Provisional data appears to show that during COVID-19 patients present with higher FIGO stage, undergo more open surgical procedures and more extensive surgery to manage their endometrial malignancy.ConclusionCOVID-19 appears to have impacted the diagnostic and treatment pathways of women with endometrial cancer in NI. This could be due to the postponement of laparoscopic surgery following the potential risk of aerosol generation and potential delays in diagnosis due to difficult access to primary care.

A Prospective Study of Risk Factors Associated with Seroprevalence of SARS-CoV-2 Antibodies in Healthcare Workers at a Large UK Teaching Hospital (preprint)

Background: The COVID-19 pandemic continues to grow at an unprecedented rate. Healthcare workers (HCWs) are at higher risk of SARS-CoV-2 infection than the general population but risk factors for HCW infection are not well described.Methods: We conducted a prospective sero-epidemiological study of HCWs at a UK teaching hospital using a SARS-CoV-2 immunoassay. Risk factors for seropositivity were analysed using multivariate logistic regression.Findings: 410/5,698 (7·2%) staff tested positive for SARS-CoV-2 antibodies. Seroprevalence was higher in those working in designated COVID-19 areas compared with other areas (9·47% versus 6·16%) Healthcare assistants (aOR 2·06 [95%CI 1·14-3·71]; p =0·016) and domestic and portering staff (aOR 3·45 [95% CI 1·07-11·42]; p =0·039) had significantly higher seroprevalence than other staff groups after adjusting for age, sex, ethnicity and COVID-19 working location. Staff working in acute medicine and medical sub-specialities were also at higher risk (aOR 2·07 [95% CI 1·31-3·25]; p <0·002). Staff from Black, Asian and minority ethnic (BAME) backgrounds had an aOR of 1·65 (95% CI 1·32 – 2·07; p <0·001) compared to white staff; this increased risk was independent of COVID-19 area working. The only symptoms significantly associated with seropositivity in a multivariable model were loss of sense of taste or smell, fever and myalgia; 31% of staff testing positive reported no prior symptoms.Interpretation: Risk of SARS-CoV-2 infection amongst HCWs is heterogeneous and influenced by COVID-19 working location, role, age and ethnicity. Increased risk amongst BAME staff cannot be accounted for solely by occupational factors.Funding: Wellcome Trust, Addenbrookes Charitable Trust, National Institute for Health Research, Academy of Medical Sciences, the Health Foundation and the NIHR Cambridge Biomedical Research Centre.Declaration of Interests: None to declare.Ethics Approval Statement: Ethical approval for this study was granted by the East of England – Cambridge Central Research Ethics Committee (IRAS ID: 220277).
