AIM: The object of this work was to study how National Health Service hospitals in England and Wales aimed to maintain effective and safe colorectal cancer (CRC) services during the first peak of the COVID-19 pandemic (April 2020). METHOD: A national survey was performed among all 148 hospitals providing CRC services. Information was collected about changes in referrals, diagnostic, staging and therapeutic procedures, as well as whether there was access to a 'cold site' (a hospital facility free of COVID-19). Clinicians in each hospital were also asked to give the 'single most important lesson learned' about keeping services safe and effective. RESULTS: Full responses were received from 123 (83%) hospitals, and information about 'cold sites' was available for 146 (99%). Eighty hospitals (54%) had access to a 'cold site' and this was increased in regions with higher COVID-19 infection rates (p <0.001). Of the 123 responding hospitals, 105 (85%) indicated that referrals of patients with suspected CRC had dropped by at least 30%, and 69 (56%) indicated that treatment plans were altered in at least 50% of CRC patients. However, 'cold site' availability protected the capacity for diagnostic colonoscopy (p = 0.013) and CRC resection (p = 0.010). Many 'lessons learned' highlighted the importance of adequate structural service organization, often mentioning 'cold sites' and regional coordination as examples, good communication and triage of patients based on clinical urgency. CONCLUSION: Access to 'cold sites', as well as regional coordination, clear communication and strong leadership, were found to be pivotal in maintaining capacity for diagnosis and treatment of CRC during the COVID-19 surge.

The impact of the first peak of the COVID-19 pandemic on colorectal cancer services in England and Wales: A national survey.

To compare the management and outcomes of colorectal cancer (CRC) patients during the first 2 months of the COVID-19 pandemic with the preceding 6 months. Background: The pandemic has affected the diagnosis and treatment of CRC patients worldwide. Little is known about the safety of major resection and whether creating "cold" sites (COVID-free hospitals) is effective. Methods: A national study in England used administrative hospital data for 14,930 CRC patients undergoing surgery between October 1, 2019, and May 31, 2020. Mortality of CRC resection was compared before and after March 23, 2020 ("lockdown" start). Results: The number of elective CRC procedures dropped sharply during the pandemic (from average 386 to 214 per week), whereas emergency procedures were hardly affected (from 88 to 84 per week). There was little change in characteristics of surgical patients during the pandemic. Laparoscopic surgery decreased from 62.5% to 35.9% for elective and from 17.7% to 9.7% for emergency resections. Surgical mortality increased slightly (from 0.9% to 1.2%, P = 0.06) after elective and markedly (from 5.6% to 8.9%, P = 0.003) after emergency resections. The observed increase in mortality during the first phase of the pandemic was similar in "cold" and "hot" sites (P > 0.5 elective and emergency procedures). Conclusions: The pandemic resulted in a 50% reduction in elective CRC procedures during the initial surge and a substantial increase in mortality after emergency resection. There was no evidence that surgery in COVID-free "cold" sites led to better outcomes in the first 2 months.

Surgical Treatment and Outcomes of Colorectal Cancer Patients During the COVID-19 Pandemic: A National Population-based Study in England

The COVID-19 pandemic has necessitated the adoption of protocols to minimize risk of periprocedural complications associated with SARS-CoV-2 infection. This typically involves a preoperative symptom screen and nasal swab RT-PCR test for viral RNA. Asymptomatic patients with a negative COVID-19 test are cleared for surgery. However, little is known about the rate of postoperative COVID-19 positivity among elective surgical patients, risk factors for this group and rate of complications.This prospective multicenter study included all patients undergoing elective surgery at 170 Veterans Health Administration (VA) hospitals across the United States. Patients were divided into groups based on first positive COVID-19 test within 30 days after surgery (COVID[-/+]), before surgery (COVID[+/-]) or negative throughout (COVID[-/-]). The cumulative incidence, risk factors for and complications of COVID[-/+], were estimated using univariate analysis, exact matching, and multivariable regression.Between March 1 and December 1, 2020 90,093 patients underwent elective surgery. Of these, 60,853 met inclusion criteria, of which 310 (0.5%) were in the COVID[-/+] group. Adjusted multivariable logistic regression identified female sex, end stage renal disease, chronic obstructive pulmonary disease, congestive heart failure, cancer, cirrhosis, and undergoing neurosurgical procedures as risk factors for being in the COVID[-/+] group. After matching on current procedural terminology code and month of procedure, multivariable Poisson regression estimated the complication rate ratio for the COVID[-/+] group vs. COVID[-/-] to be 8.4 (C.I. 4.9-14.4) for pulmonary complications, 3.0 (2.2, 4.1) for major complications, and 2.6 (1.9, 3.4) for any complication.Despite preoperative COVID-19 screening, there remains a risk of COVID infection within 30 days after elective surgery. This risk is increased for patients with a high comorbidity burden and those undergoing neurosurgical procedures. Higher intensity preoperative screening and closer postoperative monitoring is warranted in such patients because they have a significantly elevated risk of postoperative complications.

Increased complications in patients who test COVID-19 positive after elective surgery and implications for pre and postoperative screening

Background The coronavirus disease 2019 (COVID-19) pandemic has interfered with the treatment algorithm for patients with gastrointestinal (GIS) cancer, resulting in deferral of surgery We presented the outcomes of our patients to evaluate whether surgery could be safely performed and followed-up without delaying any stage of GIS cancer during the pandemic Methods This was an observational study of 177 consecutive patients who underwent elective GIS cancer surgery between March 11 and November 1, 2020 They were assessed regarding their perioperative and 60 days follow-up results for either surgical or COVID-19 status Morbidity was determined according to the Clavien-Dindo classification (CDC) Continuous and categorical data were presented as median ± SD and number with percentage (%), respectively Results The study included 44 gastric, 33 pancreatic, 40 colon, and 59 rectal cancer patients All patients underwent surgery and received neo/adjuvant treatments without delay The overall morbidity (CDC grade II-IV) and mortality rates were 101% and 39%, respectively None of the patients or medical staff were infected with COVID-19 during the study period Conclusion GIS cancer surgery can be safely performed even within a pandemic hospital if proper isolation measures can be achieved for both patients and health workers Regardless of the tumor stage, surgery should not be deferred, depending on unstandardized algorithms

Evaluating the feasibility of performing elective gastrointestinal cancer surgery during the COVID-19 pandemic: An observational study with 60 days follow-up results of a tertiary referral pandemic hospital.

The emergence of the novel coronavirus Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) and the coronavirus disease COVID-19 has impacted enormously on non-COVID-19-related hospital care. Curtailment of intensive care unit (ICU) access threatens complex surgery, particularly impacting on outcomes for time-sensitive cancer surgery. Oesophageal cancer surgery is a good example. This study explored the impact of the pandemic on process and short-term surgical outcomes, comparing the first wave of the pandemic from April to June in 2020 with the same period in 2019. Data from all four Irish oesophageal cancer centres were reviewed. All patients undergoing resection for oesophageal malignancy from 1 April to 30 June inclusive in 2020 and 2019 were included. Patient, disease, and peri-operative outcomes (including COVID-19 infection) were compared. In 2020, 45 patients underwent oesophagectomy, and 53 in the equivalent period in 2019. There were no differences in patient demographics, co-morbidities, or use of neoadjuvant therapy. The median time to surgery from neoadjuvant therapy was 8 weeks in both 2020 and 2019. There were no significant differences in operative interventions between the two time periods. There was no difference in operative morbidity in 2020 and 2019 (28% vs 40%, p = 0.28). There was no in-hospital mortality in either period. No patient contracted COVID-19 in the perioperative period. Continuing surgical resection for oesophageal cancer was feasible and safe during the COVID-19 pandemic in Ireland. The national response to this threat was therefore successful by these criteria in the curative management of oesophageal cancer.
