The Impact of COVID-19 on the Diagnosis and Treatment of Lung Cancer over a 2-Year Period at a Canadian Academic Center

Background: We have recently reported a 35% drop in new lung cancer diagnoses and a 64% drop in lung cancer surgeries during the first year of the pandemic. Methods: The target population was divided into three cohorts: pre-COVID-19 (2019), first year of COVID-19 (2020), and second year of COVID-19 (2021). Results: The number of new lung cancer diagnoses during the second year of the pandemic increased by 75%, with more than 50% being in the advanced/metastatic stage. There was a significant increase in cases with multiple extrathoracic sites of metastases during the pandemic. During the first year of the pandemic, significantly more patients were treated with radiosurgery compared to the pre-COVID-19 year. During the second year, the number of radiosurgery and surgical cases returned to pre-COVID-19 levels. No significant changes were observed in systemic chemotherapy and targeted therapy. No statistical difference was identified in the mean wait time for diagnosis and treatment during the three years of observation. However, the wait time for surgery was prolonged compared to the pre-COVID-19 cohort. Conclusions: The significant drop in new diagnoses of lung cancer during the first year of the pandemic was followed by an almost two-fold increase in the second year, with the increased rate of metastatic disease with multiple extra-thoracic site metastases. Limited access to surgery resulted in the more frequent use of radiosurgery.     

The National Lung Cancer Audit: The Impact of COVID-19

Since 2014, the National Lung Cancer Audit (NLCA) has been evaluating the performance of the UK NHS lung cancer services against established standards of care. Prior to the onset of the COVID-19 pandemic, the NLCA's annual reports revealed a steady stream of improvements in early diagnosis, access to surgery, treatment with anti-cancer therapies, input from specialist nursing and survival for patients with lung cancer in the NHS. In January 2022, the NLCA reported on the negative impact COVID-19 has had on all aspects of the lung cancer diagnosis and treatment pathway within the NHS. This article details the fundamental changes made to the NLCA data collection and analysis process during the COVID-19 pandemic and details the negative impact COVID-19 had on NHS lung cancer patient outcomes during 2020.     

The Short-Term Impact Of COVID-19 Pandemic on Cervical Cancer Screening: A Systematic Review and Meta-Analysis

Objective: A systematic review and meta-analysis were carried out to assess the pooled proportion of women screened for cervical cancer before and during the COVID-19 pandemic. Methods: After ruling out registered or ongoing systematic reviews in the PROSPERO database regarding the impact of the COVID-19 pandemic in cervical cancer screening, the protocol of our systematic review and meta-analysis was registered in PROSPERO (CRD42021279305). The electronic databases were searched for articles published in English between January 2020 and October 2021and the study was designed based on PRISMA guidelines updated in 2020. Meta-analysis was accomplished in STATA version 13.0 (College Station, Texas 77,845 USA). The pooled proportion of women who had undergone cervical cancer screening was reported with 95% CI. In order to quantify the heterogeneity, Chi2 statistic (Q statistic) and I2 index were used. Results: The meta-analysis included seven studies from Slovenia, Italy, Ontario (Canada), Scotland, Belgium, and the USA, comprising 403,986 women and 199,165 women who were screened for cervical cancer before the COVID-19 pandemic in 2019 and during the pandemic in 2020, respectively. The pooled proportion of women screened for cervical cancer in 2019 was 9.79% (95% CI 6.00%-13.59%, 95% prediction interval 0.42%-23.81%). During the pandemic, the pooled proportion of screened women declined to 4.24% (95% CI 2.77%-5.71%, 95% prediction interval 0.9%-17.49%). Conclusion: There was a substantial drop in the cervical cancer screening rate due to lockdowns and travel restrictions to curb the COVID-19 pandemic. Scaling up cervical cancer screening strategies is essential to prevent the long-term impact of cervical cancer burden.

Reduced Fractionation in Lung Cancer Patients Treated with Curative-intent Radiotherapy during the COVID-19 Pandemic

Patients treated with curative-intent lung radiotherapy are in the group at highest risk of severe complications and death from COVID-19. There is therefore an urgent need to reduce the risks associated with multiple hospital visits and their anti-cancer treatment. One recommendation is to consider alternative dose-fractionation schedules or radiotherapy techniques. This would also increase radiotherapy service capacity for operable patients with stage I-III lung cancer, who might be unable to have surgery during the pandemic.Here we identify reduced-fractionation for curative-intent radiotherapy regimes in lung cancer, from a literature search carried out between 20/03/2020 and 30/03/2020 as well as published and unpublished audits of hypofractionated regimes from UK centres. Evidence, practical considerations and limitations are discussed for early-stage NSCLC, stage III NSCLC, early-stage and locally advanced SCLC. We recommend discussion of this guidance document with other specialist lung MDT members to disseminate the potential changes to radiotherapy practices that could be made to reduce pressure on other departments such as thoracic surgery. It is also a crucial part of the consent process to ensure that the risks and benefits of undergoing cancer treatment during the COVID-19 pandemic and the uncertainties surrounding toxicity from reduced fractionation have been adequately discussed with patients. Furthermore, centres should document all deviations from standard protocols, and we urge all colleagues, where possible, to join national/international data collection initiatives (such as COVID-RT Lung) aimed at recording the impact of the COVID-19 pandemic on lung cancer treatment and outcomes.     

The Impact of COVID-19 on Academic Cancer Clinical Trials in Canada and the Initial Response from Cancer Centers

The COVID-19 pandemic resulted in temporary holds placed on new trial startups, patient recruitment and follow up visits for trials which contributed to major disruptions in cancer center trial unit operations. To assess the impact, the Canadian Cancer Clinical Trials Network (3CTN) members participated in regional meetings and a survey to understand the impact of the pandemic to academic cancer clinical trials (ACCT) activity, cancer trial unit operations and supports needed for post-pandemic recovery. Trial performance and recruitment data collected from 1 April 2020–31 March 2021 was compared to the same period in previous years. From 1 April–30 June 2020, patient recruitment decreased by 67.5% and trial site activations decreased by 81% compared to the same period in 2019. Recovery to reopening and recruitment of ACCTs began after three months, which was faster than initially projected. However, ongoing COVID-19 impacts on trial unit staffing and operations continue to contribute to delayed trial activations, lower patient recruitment and may further strain centers’ capacity for participation in academic-sponsored trials.     

The Psychosocial Impact of COVID-19 on Older Adults with Cancer: A Rapid Review

Background: Older adults with cancer are amongst the most vulnerable population to be negatively impacted by COVID-19 due to their likelihood of comorbidities and compromised immune status. Considering the longevity of the pandemic, understanding the subjective perceptions and psychosocial concerns of this population may help ameliorate the psychological aftermath. In this review, we systematically analyze the literature surrounding the psychosocial impact and coping strategies among older adults with cancer within the context of COVID-19. Methods: We conducted a rapid review of literature following PRISMA guidelines between January 2020 to August 2021 using (1) MEDLINE, (2) Embase, (3) CINAHL, and (4) PsychINFO and keyword searches for “cancer” and “COVID-19” focused on adults 65 years or older. Results: Of the 6597 articles screened, 10 met the inclusion criteria. Based on the included articles, the psychosocial impact of COVID-19 was reported under four domains, (1) impact of COVID-19 on quality of life (QoL), (2) concerns related to COVID-19, (3) coping with the impact of COVID-19, and (4) recommendations for future care. Results pertaining to perceived quality of life were inconsistent across the included articles. The most common concerns related to: contracting COVID-19, survivorship transitions, and feelings of isolation. Coping strategies reported by older adults included: spiritual care, lived experience, acceptance, and positive reinterpretation. Conclusions: We found many psychosocial impacts of the pandemic on older adults with cancer. The findings from this review can inform interventions related to shared decision-making and tailored patient care in the future.     

Considerations for the Surgical Management of Early Stage Lung Cancer During the COVID-19 Pandemic

The highly transmissible novel coronavirus (COVID-19) has infected over 8.8 million people globally and has upended the delivery of health care in the United States, creating unprecedented challenges to providing care to patients with early stage non–small cell lung cancer (NSCLC). The initial surge of patients with COVID-19 that have flooded hospitals has put a strain on physical space, workforce, and supplies. In addition, social distancing and the risk of COVID-19 transmission has created significant barriers for thoracic surgeons to diagnose and treat patients. Many hospitals across the country have temporarily suspended elective operations to preserve hospital beds, ventilators, and personal protective equipment. Currently, the pandemic has greatly disrupted the current standard of resection after adequate staging with imaging and/or surgical staging for early stage NSCLC well beyond the initial acute phase; therefore, a new paradigm for effective management will need to be devised until the COVID-19 pandemic is eradicated with systematic vaccination and herd immunity. Thoracic surgeons will need to recalibrate their approach to ensure that patients receive timely and effective treatment for early stage NSCLC. The management of early stage NSCLC during the COVID-19 pandemic should be balanced with available hospital resources, risk of progression of disease, risk of transmission of COVID-19 to patient and surgeon, and the availability of alternative therapies. This article will address the current challenges with treating early stage NSCLC during the COVID-19 pandemic and provide a clinical framework for providing effective surgical therapy while mitigating the risk of transmission of the SARS-CoV-2 virus to patients and surgeons.     

A Review of Canadian Cancer-Related Clinical Practice Guidelines and Resources during the COVID-19 Pandemic

(1) Background: Preventive measures taken in response to the coronavirus disease 2019 (COVID-19) pandemic have adversely affected an entire range of cancer-related medical activities. The reallocation of medical resources, staff, and ambulatory services, as well as critical shortages in pharmaceutical and medical supplies have compelled healthcare professionals to prioritize patients with cancer to treatment and screening services based on a set of classification criteria in cancer-related guidelines. Cancer patients themselves have been affected on multiple levels, and addressing their concerns poses another challenge to the oncology community. (2) Methods: We conducted a Canada-wide search of cancer-related clinical practice guidelines on the management and prioritization of individuals into treatment and screening services. We also outlined the resources provided by Canadian cancer charities and patient advocacy groups to provide cancer patients, or potential cancer patients, with useful information and valuable support resources. (3) Results: The identified provincial guidelines emphasized cancer care (i.e., treatment) more than cancer control (i.e., screening). For cancer-related resources, a clear significance was placed on knowledge & awareness and supportive resources, mainly relating to mental health. (4) Conclusion: We provided a guidance document outlining cancer-related guidelines and resources that are available to healthcare providers and patients across Canada during the COVID-19 pandemic.     

Measuring Occupational Fatigue among Higher and Middle Management at a Specialized Cancer Center during the COVID-19 Pandemic

Purpose: This study aims to measure the occupational fatigue level and describe the sources and consequences of occupational fatigue among middle and higher management at an international specialized cancer center during the COVID-19 pandemic. Methods: A mixed-method design was used in this study. A convenience sampling technique was utilized to select the participants from King Hussein Cancer Center, Amman, Jordan. The data was collected through a self-administered questionnaire. This questionnaire included both quantitative and qualitative sections. We utilized Fatigue Risk Assessment and Management in High-Risk Environments (FRAME)-26 items scale for the quantitative section. Two main questions were included in the survey to identify the sources and consequences of occupational fatigue.Results: The results show that the average mean of occupational fatigue was 2.95/5 (SD=0.70). The level of changes in fatigue levels after the COVID-19 pandemic increased by 0.87/3 (SD=1.45). The sources of occupational fatigue could be categorized into five themes: workload, work environment, staffing, psychological, and physical sources. There are four themes categorizing occupational fatigue: social, economic, health, and daily activity and lifestyle. Conclusion: This study affords valuable insight into the level, source, and consequences of occupational fatigue among middle and higher management at an international specialized cancer hospital in developing countries. The results indicate that the occupational fatigue level was moderate, and the fatigue level was negatively impacted by the COVID-19 pandemic.     

Safety of COVID-19 Vaccine in Patients with Cancer in a High-Volume Comprehensive Cancer Center

BackgroundFew data are available on the safety of COVID-19 vaccines in cancer patients undergoing active cancer-directed treatment.Patients and MethodsThis case series analyzes outcomes in terms of adverse events in 5297 patients undergoing anti-cancer treatment who were vaccinated with anti-SARS-CoV-2 Pfizer-BioNTech vaccine at a single cancer center from March 6, 2021 to May 9, 2021. Adverse events were retrieved from the national Italian pharmacovigilance platform (http://www.vigicovid.it).ResultsOf the 5297 patients treated for either solid tumors (87%) or onco-hematologic malignancies (13%) who were vaccinated, 8 adverse drug reactions (ADRs) were reported. One was a severe ADR and 7 were non-severe ADRs. Non-severe ADRs resolved within 48 hours.ConclusionBNT162b2 Pfizer-BioNTech vaccine was safely administered in the largest cohort of cancer patients reported to date.

COVID-19 Outcomes Among Patients With Cancer: Observations From the University of California Cancer Consortium COVID-19 Project Outcomes Registry

BackgroundThe risks associated with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and its associated illness, coronavirus disease 2019 (COVID-19), among patients with a cancer diagnosis have not been fully characterized. This study leverages data from a multi-institutional cohort study, the University of California Cancer COVID Consortium, to evaluate outcomes associated with SARS-CoV-2 infection among patients with cancer.MethodsClinical data were collected from March to November 2020 and included patient demographics, cancer history and treatment, SARS-CoV-2 exposure and testing, and COVID-19 clinical management and outcomes. Multivariate ordinal logistic regression permitting unequal slopes was used to evaluate the impact of demographic, disease, and treatment factors on SARS-CoV-2 related hospitalization, intensive care unit (ICU) admission, and mortality.FindingsAmong all evaluated patients (n = 303), 147 (48%) were male, 118 (29%) were older adults (≥65 years old), and 104 (34%) were non-Hispanic white. A subset (n = 63, 21%) had hematologic malignancies and the remaining had solid tumors. Patients were hospitalized for acute care (n = 79, 26%), ICU-level care (n = 28, 9%), or died (n = 21, 7%) due to COVID-19. Patients with ≥2 comorbidities were more likely to require acute care (odds ratio [OR] 2.09 [95% confidence interval (CI), 1.23-3.55]). Cough was identified as a significant predictor of ICU hospitalization (OR 2.16 [95% CI, 1.03-4.57]). Importantly, mortality was associated with an active cancer diagnosis (OR 3.64 [95% CI, 1.40-9.5]) or advanced age (OR 3.86 [95% CI, 1.2-12.44]).InterpretationThis study observed that patients with active cancer or advanced age are at an increased risk of death from COVID-19. These study observations can inform risk counseling related to COVID-19 for patients with a cancer diagnosis.

Temporal Trends in Inpatient Oncology Census Before and During the COVID-19 Pandemic and Rates of Nosocomial COVID-19 Among Patients with Cancer at a Large Academic Center

BackgroundThe coronavirus disease 2019 (COVID‐19) pandemic has significantly impacted health care systems. However, to date, the trend of hospitalizations in the oncology patient population has not been studied, and the frequency of nosocomial spread to patients with cancer is not well understood. The objectives of this study were to evaluate the impact of COVID‐19 on inpatient oncology census and determine the nosocomial rate of COVID‐19 in patients with cancer admitted at a large academic center.Materials and MethodsMedical records of patients with cancer diagnosed with COVID‐19 and admitted were reviewed to evaluate the temporal trends in inpatient oncology census during pre–COVID‐19 (January 2019 to February 2020), COVID‐19 (March to May 2020), and post–COVID‐19 surge (June to August 2020) in the region. In addition, nosocomial infection rates of SARS‐CoV‐2 were reviewed.ResultsOverall, the daily inpatient census was steady in 2019 (median, 103; range, 92–118) and until February 2020 (median, 112; range, 102–114). However, there was a major decline from March to May 2020 (median, 68; range, 57–104), with 45.4% lower admissions during April 2020. As the COVID‐19 surge eased, the daily inpatient census over time returned to the pre–COVID‐19 baseline (median, 103; range, 99–111). One patient (1/231, 0.004%) tested positive for SARS‐CoV‐2 13 days after hospitalization, and it is unclear if it was nosocomial or community spread.ConclusionIn this study, inpatient oncology admissions decreased substantially during the COVID‐19 surge but over time returned to the pre–COVID‐19 baseline. With aggressive infection control measures, the rates of nosocomial transmission were exceedingly low and should provide reassurance to those seeking medical care, including inpatient admissions when medically necessary.Implications for PracticeThe COVID‐19 pandemic has had a major impact on the health care system, and cancer patients are a vulnerable population. This study observes a significant decline in the daily inpatient oncology census from March to May 2020 compared with the same time frame in the previous year and examines the potential reasons for this decline. In addition, nosocomial rates of COVID‐19 were investigated, and rates were found to be very low. These findings suggest that aggressive infection control measures can mitigate the nosocomial infection risk among cancer patients and the inpatient setting is a safe environment, providing reassurance.     

Changes in the Management of Patients having Radical Radiotherapy for Lung Cancer during the First Wave of the COVID-19 Pandemic in the UK

AimsIn response to the COVID-19 pandemic, guidelines on reduced fractionation for patients treated with curative-intent radiotherapy were published, aimed at reducing the number of hospital attendances and potential exposure of vulnerable patients to minimise the risk of COVID-19 infection. We describe the changes that took place in the management of patients with stage I–III lung cancer from April to October 2020.Materials and methodsLung Radiotherapy during the COVID-19 Pandemic (COVID-RT Lung) is a prospective multicentre UK cohort study. The inclusion criteria were: patients with stage I–III lung cancer referred for and/or treated with radical radiotherapy between 2nd April and 2nd October 2020. Patients who had had a change in their management and those who continued with standard management were included. Data on demographics, COVID-19 diagnosis, diagnostic work-up, radiotherapy and systemic treatment were collected and reported as counts and percentages. Patient characteristics associated with a change in treatment were analysed using multivariable binary logistic regression.ResultsIn total, 1553 patients were included (median age 72 years, 49% female); 93 (12%) had a change to their diagnostic investigation and 528 (34%) had a change to their treatment from their centre's standard of care as a result of the COVID-19 pandemic. Age ≥70 years, male gender and stage III disease were associated with a change in treatment on multivariable analysis. Patients who had their treatment changed had a median of 15 fractions of radiotherapy compared with a median of 20 fractions in those who did not have their treatment changed. Low rates of COVID-19 infection were seen during or after radiotherapy, with only 21 patients (1.4%) developing the disease.ConclusionsThe COVID-19 pandemic resulted in changes to patient treatment in line with national recommendations. The main change was an increase in hypofractionation. Further work is ongoing to analyse the impact of these changes on patient outcomes.     

Impact of the COVID-19 Pandemic on the Diagnosis and Surgery of Breast Cancer: A Multi-Institutional Study

PurposeThe coronavirus disease 2019 (COVID-19) pandemic has significantly impacted the rates of screening, case identification, and referral for cancer diagnosis. We investigated the diagnosis and surgery status of breast cancer before and after the COVID-19 pandemic at a multi-institutional level.MethodsWe collected breast cancer data from the clinical data warehouse which contained the medical records of patients from six academic institutions in South Korea. Patients were divided into two groups: February to April (period A) and May to July (period B). The data from the two groups were then compared against the same periods in 2019 and 2020. The primary objective was to investigate the differences in breast cancer stages before and after the COVID-19 pandemic.ResultsAmong 3,038 patients, there was a 9.9% reduction in the number of diagnoses in 2020. This decrease was more significant during period A than period B. The breast cancer stage was not statistically different in period A (p = 0.115), but it was in period B (p = 0.001). In the subset analysis according to age, there was a statistical difference between 2019 and 2020 in period B for patients under the age of 65 years (p = 0.002), but no difference was observed in the other groups.ConclusionThe number of breast cancer cases declined during the pandemic, and the staging distribution has changed after the pandemic peak.
