Details of data sources and methods can be found in the appendix (p 2). We calculated the percentage change in diagnostic oesophago gastro-duodenoscopies in each hospital trust associated with the COVID-19 pandemic. Data regarding the number of deaths due to COVID-19 per bed for each hospital trust over the 4-month study period were used to consider the effects of the burden of COVID-19 on the provision of oeso phago gastro-duodenoscopy by trust. Published data from the national oesophagogastric cancer audit6 from 2016 to 2018 was used to estimate the number of oesophageal and gastric cancers that might not have been diagnosed during this 4-month study period as a result of changes in the number of diagnostic oesophagogastroduodenoscopies done. Trusts with incomplete data over the study period were excluded and trusts that merged during the study period were treated as merged throughout (appendix p 3).The number of diagnostic endo-scopies done between January, 2020, and April, 2020, in the 122 analysed trusts was around 28% lower than in the same period in 2019 (149 043 vs 208 212). Compared with the same period in 2019, activity was slightly lower in January, 2020 (53 909 vs 54 979; 2·0%), and February, 2020 (49 906 vs 50 572; 1·3%). Activity fell considerably in March, 2020 (37 854 vs 54 520 in March, 2019; 30·6%) and in April, 2020 (5638 vs 49 877 in April, 2019; 88·7%). In April, 2020, activity was more than 90% lower than in April, 2019, in 83 (68%) of 122 trusts and in 12 (63%) of 19 vanguards.We found no correlation between the number of deaths due to COVID-19 per bed and the percentage change in diagnostic oesophago gastro-duo denoscopies during the study period, both at the hospital trust level (Spearman R=–0·04; p=0·66) and at the cancer vanguard level (–0·24; p=0·33; appendix p 5).Based on the reductions seen in diagnostic oesophago gastro duo-denoscopy, the estimated number of undiagnosed oesophageal and gastric cancers across England was 750, with a median of 47·3 (IQR 35·7–57·5) across cancer vanguards (appendix p 5). The estimated number of undiagnosed oesophageal and gastric cancers that would have been treated curatively across England was 213, with a median of 11·0 (IQR 6·3–14·4) across cancer vanguards (appendix p 5).Oesophageal and gastric cancers are particularly aggressive with a poor prognosis, primarily driven by a delayed presentation and advanced stage at diagnosis. The COVID-19 pandemic has led to huge reductions in diagnostic oesophago gastro-duo denoscopies across England; as a result, a proportionally large number of patients with oesophageal and gastric cancer will remain undiagnosed. In England and Wales, approximately 30% of patients with oesophageal and gastric cancers are treated curatively; our data suggest that delays in diagnosis caused by the reduction in oeso phago gastro-duodenoscopy services will mean increasing numbers of patients presenting with advanced disease, who are less likely to be treated curatively.5 Furthermore, time from diagnosis to initiation of treatment is often used as a quality metric for efficiency of the cancer treatment pathway.6 Large increases in waiting lists for oncological and surgical treatment as a result of COVID-19 will substantially affect cancer waiting times, although the true effect of this delay on trust performance is not yet known, in part because oesophago-gastro duodenoscopy screening pathways for oesophageal and gastric cancer in England are being reinstated at varied rates across hospital trusts. The necessary national endoscopy uptake and capacity for optimum diagnostic screening during the COVID-19 recovery compared with baseline is unclear. Regardless, clear oncological and surgical pathway planning is urgently needed so that upper gastrointestinal cancer services are able to adapt to the surge in new upper gastrointestinal cancer diagnoses that will inevitably be See Online for appendixLancet Gastroenterol Hepatol 2020Published Online July 16, 2020 https://doi.org/10.1016/ S2468-1253(20)30236-3Correspondence2 www.thelancet.com/gastrohep   Published online July 16, 2020   https://doi.org/10.1016/S2468-1253(20)30236-3detected. One proposed strategy is the creation of cancer hubs that will provide capacity.7 However, these hubs must be modelled to account for local patient factors, hospital capacity, and likely endoscopic detection rates.JK reports grants from H2020 (ITN grant; GROWTH consortium), grants from the UK National Institute for Health Research (i4i grant; iEndoscope), grants from Cancer Research UK fellowship (PhD studentship), educational grants from Johnson and Johnson (PanSurg.org) and personal fees from Verb Robotics/Ethicon and Medtronic.
