ABSTRACT
Background Cancer has been assumed to be associated with a high-risk of morbidity and mortality from COVID-19. Protective measures have incorporated modifications in cancer treatments. There are conflicting data about the impact of COVID-19 infection and outcomes in cancer patients. We aim to describe the impact of demographic and clinical characteristics on COVID-19 outcomes in patients with cancer in Northern Ireland reported within the UK Coronavirus Cancer Monitoring Project (UKCCMP). Method Prospective data collection including demographics, cancer stage and type, treatment and outcomes occurred for all Northern Irish patients enrolled in the UKCCMP. The primary endpoint was all-cause mortality. Descriptive statistics and logistic regression analysis were performed using SPSSv25. Results Between March 2020 and March 2021, 110 cases were registered. Median age was 63 years (range 27 to 87). Seventy patients (63.6%) were >60 years and 59 (53.8%) were females. Co-morbidities were reported in 83 patients (72.7%). Most patients had metastatic disease (64, 58.2%). Sixty-seven patients (60.9%) received anticancer treatment in the 4 weeks prior to COVID-19 infection. Of those patients, 35 (52.2%) received chemotherapy. Thirty-nine patients (58.2%) continued treatment as planned;24 (36.9%) stopped treatment due to SARS-CoV-2 infection. The majority of patients were asymptomatic or experienced mild symptoms (67, 60.9%). Fifty-one (46.3%%) were admitted to hospital for COVID-19. Risk of severe/critical COVID-19 disease was significantly associated with age (OR 1.07 [95% CI 1.03-1.11);p=0.004), pre-existing hypertension (OR 3.29 [95% CI 1.42-7.62];p=0.02) and thoracic primary malignancy (OR 4.41 [95% CI 1.52-12.74];p=0.042). Twenty-nine patients (26.3%) died of whom 15 (57.7%) died of COVID-19 and 13 (44.8%) died due to cancer. Risk of death was significantly associated with age (OR 1.05 [95% CI 1.01-1.09];p=0.014), male sex (OR 3.76 [95% CI 1.51-9.34];p=0.008) and thoracic primary malignancy (OR 5.35 [95% CI 1.88-15.25];p=0.014). When corrected for age, gender and co-morbidities, chemotherapy within the past 4 weeks was not significantly associated with mortality (OR 0.65 [95% CI 0.20-2.11];p=0.476). Conclusion Age and thoracic cancer diagnosis correlated with survival. Comparison of performance during the pandemic with national benchmarks can inform how regional services should be adapted in preparation for future healthcare crises.
ABSTRACT
Background The COVID-19 pandemic has placed an inexorable strain on endoscopy services worldwide, affecting the diagnosis of oesophago-gastric (OG) cancer and Barrett’s oesophagus (BO). As coronavirus infection rates rose many professional bodies advised that all endoscopy, except emergency and essential procedures be stopped immediately. We sought to quantify the decline in OG cancer and BO diagnoses following implementation of British Society of Gastroenterology (BSG) guidance related to COVID-19 and the psychosocial effects on BO patients. Methods We examined OG cancer and BO diagnoses in Northern Ireland from March-September 2020 and compared them with the three-year average number of patients during the same time period (corresponding to weeks 10-37) between 2017-2019 by utilising Northern Ireland Cancer Registry (NICR) data. The psychosocial impact of COVID-19 was assessed using an online survey, which included validated WHOQOL-BREF and EQ-5D-5L quality of life measures, and was completed by 24 BO patients from April-May 2020. Results Between March and September 2020 in Northern Ireland, the proportion of OG cancer and BO diagnoses declined by 26.6% and 59.3%, respectively, compared to expected levels. In April, BO diagnoses fell by 95.5% but by September, whilst OG cancer rates had returned to baseline, BO cases remained supressed by approximately 20%. We estimate that these declines in diagnosis represent 53 ‘missed’ OG cancer and 236 ‘missed’ BO diagnoses. In the online survey sample, BO patients reported consistently lower quality of life scores than population norms, and highlighted a number of concerns with regard to their health and care. Conclusions The COVID-19 pandemic has resulted in an abrupt decline in OG cancer and BO diagnoses and has profoundly impacted the wellbeing of BO patients. Our study represents the first report of the impact of COVID-19 on the diagnosis of BO. Strategies to mitigate the ongoing effects of the pandemic are urgently required to preserve the ability to rapidly detect and diagnose cancer and pre-malignant conditions.
ABSTRACT
BACKGROUND: The restructuring of healthcare systems to cope with the demands of the COVID-19 pandemic has led to a reduction in clinical services such as cancer screening and diagnostics. METHODS: Data from the four Northern Ireland pathology laboratories were used to assess trends in pathological cancer diagnoses from 1st March to 12th September 2020 overall and by cancer site, sex and age. These trends were compared to the same timeframe from 2017 to 2019. RESULTS: Between 1st March and 12th September 2020, there was a 23% reduction in cancer diagnoses compared to the same time period in the preceding 3 years. Although some recovery occurred in August and September 2020, this revealed inequalities across certain patient groups. Pathological diagnoses of lung, prostate and gynaecological malignancies remained well below pre-pandemic levels. Males and younger/middle-aged adults, particularly the 50-59-year-old patient group, also lagged behind other population demographic groups in terms of returning to expected numbers of pathological cancer diagnoses. CONCLUSIONS: There is a critical need to protect cancer diagnostic services in the ongoing pandemic to facilitate timely investigation of potential cancer cases. Targeted public health campaigns may be needed to reduce emerging inequalities in cancer diagnoses as the COVID-19 pandemic continues.
