Diagnosis, treatment, and outcome of patients with oesophagogastric cancer during the COVID-19 pandemic: national study.

BACKGROUND: The national response to COVID-19 has had a significant impact on cancer services. This study investigated the effect of national lockdown on diagnosis, management, and outcomes of patients with oesophagogastric cancers in Scotland. METHODS: This retrospective cohort study included consecutive new patients presenting to regional oesophagogastric cancer multidisciplinary teams in National Health Service Scotland between October 2019 and September 2020. The study interval was divided into before and after lockdown, based on the first UK national lockdown. Electronic health records were reviewed and results compared. RESULTS: Some 958 patients with biopsy-proven oesophagogastric cancer in 3 cancer networks were included: 506 (52.8 per cent) before and 452 (47.2 per cent) after lockdown. Median age was 72 (range 25-95) years and 630 patients (65.7 per cent) were men. There were 693 oesophageal (72.3 per cent) and 265 gastric (27.7 per cent) cancers. Median time to gastroscopy was 15 (range 0-337) days before versus 19 (0-261) days after lockdown (P < 0.001). Patients were more likely to present as an emergency after lockdown (8.5 per cent before versus 12.4 per cent after lockdown; P = 0.005), had poorer Eastern Cooperative Oncology group performance status, were more symptomatic, and presented with a higher stage of disease (stage IV: 49.8 per cent before versus 58.8 per cent after lockdown; P = 0.04). There was a shift to treatment with non-curative intent (64.6 per cent before versus 77.4 per cent after lockdown; P < 0.001). Median overall survival was 9.9 (95 per cent c.i. 8.7 to 11.4) months before and 6.9 (5.9 to 8.3) months after lockdown (HR 1.26, 95 per cent c.i. 1.09 to 1.46; P = 0.002). CONCLUSION: This national study has highlighted the adverse impact of COVID-19 on oesophagogastric cancer outcomes in Scotland. Patients presented with more advanced disease and a shift towards treatment with non-curative intent was observed, with a subsequent negative impact on overall survival.

One year experience of a newly established super green ERAS pathway for performing oesophago-gastric cancer resections during the Covid-19 pandemic

Background Surgical oncology services in the UK have been impacted by the COVID-19 pandemic.  Various strategies have been employed in an attempt to continue cancer resectional surgery   during the pandemic.  This study examined our institution’s experience and outcomes with a newly established Super Green ERAS pathway for oesophago-gastric (OG) cancer resections during the pandemic. Methods A retrospective cohort study of consecutive patients who had a resection for OG cancer performed over a 12-month period beginning from the date of the first UK National Lockdown of 23 March 2020.  Barring two intervals each lasting 3 weeks, urgent elective cancer surgery continued on our mixed hot and cold site through the establishment of a Super Green ERAS pathway. Patients were confirmed COVID-19 negative within 72 hours pre-admission and retested  72-hourly post-op. 14 days self-isolation pre-admission was mandated.  Patients not complying had their surgery postponed. Transhiatal oesophagectomy was the preferred approach for oesophagectomy during the pandemic.  Results 45 resections (33 oesophagectomies, 10 gastrectomies and 2 trial of dissections) were performed.  37 (82.2%) patients were male with a median age of 64 (IQR 58-71) years.   3 patients were postponed due to non-adherence with self-isolation. No patients tested positive for COVID-19 post-operatively, hence, there was no COVID-19-related morbidity. Nine patients developed pneumonia. Seven patients had an anastomotic leak, all of whom were successfully rescued. One patient required a clamshell thoracotomy due to intra-operative mediastinal bleeding followed by a return to theatre for reconstruction 48hrs later.  Median length of stay was 12 (IQR 9-18) days. There was no in-hospital mortality. Conclusions OG cancer resections can be performed safely despite COVID-19, with favorable clinical outcomes when a Super Green ERAS pathway is strictly adhered to.   Implementation of such pathways will enable surgical oncology services, including OG cancer resections, to continue to ensure best possible outcomes for cancer patients despite any future waves of the COVID-19 pandemic.

Stage Migration in Newly Diagnosed Oesophago-gastric Cancer during the first wave of COVID-19 Pandemic

Background Covid-19 has significantly disrupted elective and emergency health care provision including cancer care within the UK. The aim of the study was to investigate the impact of the pandemic on the staging of oesophago-gastric cancers at presentation, determine the time delay in performing gastroscopy and the multidisciplinary team (MDT) treatment outcomes. Methods A retrospective cohort study of all newly diagnosed oesophago-gastric cancers (adenocarcinoma and squamous cell carcinoma) in a single regional MDT was performed between 1st October 2019 and 30th September 2020. Electronic records were interrogated and patients dichotomised into two groups with those presenting before the introduction of the UK national lockdown of 23rd March 2020 compared to those presenting post-lockdown. Results 349 new oesophago-gastric cancer patients were discussed in the MDT (192 pre-lockdown versus 157 post-lockdown). Demographics were evenly matched between the two groups. More patients presented as an emergency admission post-lockdown (28.0% vs 12.5%, p < 0.001). Median waiting time for gastroscopy was longer post-lockdown (23 vs 14 days, p = 0.035). Metastatic disease at presentation was more frequent post-lockdown (47.8% vs 33.3%, p = 0.008). Overall, more patients had a palliative rather than curative treatment intent post-lockdown (71.3% vs 57.8%, p = 0.005). Conclusions The Covid-19 pandemic has had a significant negative effect on the stage of oesophago-gastric cancers at presentation. This has translated into more patients receiving palliative treatment and ultimately having a poorer prognosis. This study highlights the importance of maintaining cancer services during the Covid-19 pandemic.
