EGS P10 The Effect of COVID-19 on the Management of Upper Gastro-intestinal Cancers at a London NHS Trust


 
 
 The advent of the COVID-19 pandemic in 2020 led to staff redeployment and prioritization of urgent care services. Cancer services were impacted by staff and resource diversion. Cancer diagnoses fell by 33% due to reduction in surveillance, diagnosis, and screening. Upper gastro-intestinal cancers (UGI) include cancers of the esophagus, stomach, small intestine, pancreas, liver, and gall bladder. These cancers progress insidiously, present at late stages and are challenging to treat. Delayed diagnosis significantly reduces the scope of treatment options available and therefore impacts the prognosis of the patient. A Public Health England Report in 2021 showed a reduction in tumor resection surgeries in UGI cancers between March to May 2020 and December to February 2021. The backlog of surgical cancer management is ongoing as the pandemic evolves and NHS service provisions adapt. It is important to understand the effects of COVID-19 on diagnosis, staging and treatment of UGI cancers in order to improve service provision in the ensuing years.
 
 
 
 This was a cross-sectional study conducted at Barking, Havering and Redbridge NHS Trust from January to June 2019, 2020 and 2021. Data for 316 study participants was sourced from the Somerset Cancer Database and supplemented with data from electronic patient care records. Six months of data was compared in 2019 (pre-pandemic), 2020 (mid-pandemic including the first lockdown) and 2021. The data was analysed as raw proportions and percentages.
 
 
 
 The number of UGI cancers diagnosed was lowest in 2020 during the height of the pandemic compared to 2019 and 2021. The most common cancer in all three years was pancreatic. Pancreatic cancer was also the most common emergency cancer presentation. The highest proportion of stage IV cancers presented in 2021 (67%). The proportion of cases that resulted in palliative care management increased from 2019 to 2021 (67% and 70% respectively). 53% of all patients came from neighbourhoods that fell within 50% of the most deprived areas nationally.
 
 
 
 The COVID-19 pandemic has had variable impacts on the presentation and management of UGI cancers at the BHRUT NHS Trust. This study exhibits local trends and percentages following suit from Public Health England's National Cancer Registration and Analysis Service data for trend-based discussion. Further research within London NHS Trusts is encouraged to understand the full impact of COVID-19 on surgical cancer services in the NHS.
