Changes in anticancer treatment plans in patients with solid cancer hospitalized with COVID-19: analysis of the nationwide BSMO-COVID registry providing lessons for the future.

BACKGROUND: Solid cancer is an independent prognostic factor for poor outcome with COVID-19. As guidelines for patient management in that setting depend on retrospective efforts, we here present the first analyses of a nationwide database of patients with cancer hospitalized with COVID-19 in Belgium, with a focus on changes in anticancer treatment plans at the time of SARS-CoV-2 infection. METHODS: Nineteen Belgian hospitals identified all patients with a history of solid cancer hospitalized with COVID-19 between March 2020 and February 2021. Demographic, cancer-specific and COVID-specific data were pseudonymously entered into a central Belgian Society of Medical Oncology (BSMO)-COVID database. The association between survival and primary cancer type was analyzed through multivariate multinomial logistic regression. Group comparisons for categorical variables were carried out through a Chi-square test. RESULTS: A total of 928 patients were registered in the database; most of them were aged ≥70 years (61.0%) and with poor performance scores [57.2% Eastern Cooperative Oncology Group (ECOG) ≥2]. Thirty-day COVID-related mortality was 19.8%. In multivariate analysis, a trend was seen for higher mortality in patients with lung cancer (27.6% versus 20.8%, P = 0.062) and lower mortality for patients with breast cancer (13.0% versus 23.3%, P = 0.052) compared with other tumour types. Non-curative treatment was associated with higher 30-day COVID-related mortality rates compared with curative or no active treatment (25.8% versus 14.3% versus 21.9%, respectively, P < 0.001). In 33% of patients under active treatment, the therapeutic plan was changed due to COVID-19 diagnosis, most frequently involving delays/interruptions in systemic treatments (18.6%). Thirty-day COVID-related mortality was not significantly different between patients with and without treatment modifications (21.4% versus 20.5%). CONCLUSION: Interruption in anticancer treatments at the time of SARS-CoV-2 infection was not associated with a reduction in COVID-related mortality in our cohort of patients with solid cancer, highlighting that treatment continuation should be strived for, especially in the curative setting.

Short and medium-term outcomes of patients with solid cancer hospitalized with COVID-19 in Belgium according to cancer diagnosis and treatment characteristics

Background: Solid cancer is an independent prognostic factor for COVID-19 related mortality. Adverse prognostic factors in these patients include low performance status, lung cancer, advanced cancer stage and recent diagnosis. In this study, we further evaluated prognostic effects of cancer diagnosis and treatment variables and characterized changes in anticancer treatment plans due to COVID-19 diagnosis in a nation-wide cohort study. Methods: Patients with a history of solid cancer hospitalized with COVID-19 between March 2020 and February 2021 in one of the 20 participating institutions in Belgium were included. Patient demographics, comorbidities, COVID-19 hospitalization course and treatment, cancer and anticancer treatment characteristics, treatment changes due to COVID-19 and clinical outcomes in-hospital and during follow-up were retrospectively registered in a central database. The primary objective was to evaluate potential differences in 30-day and 3-month COVID-19-related mortality according to cancer and anticancer treatment characteristics. Results: A total of 946 patients (median age 73y, interquartile range 64-81y) were included. Pre-existing comorbidities were present in 90.1% of patients, and 21.9% had a history of > 1 malignancy. Half of the patients (n = 463, 49.3%) had received anticancer treatment ≤3 months before COVID-19 diagnosis (“active cancer”), of whom 286 (63.1%) in the non-curative setting. The overall 30-day and 3-month COVID-19- related mortality rates in this cohort were 21.4% (n = 178) and 24.1% (n = 194), respectively. COVID- related 3-month mortality was comparable in patients with active cancer (n = 96, 24.3%) and in patients with non-active cancer (n = 97, 24.0%), but within the first group COVID-related mortality was higher in those receiving systemic treatment in the non-curative (28.3%) versus the curative setting (15.2%). A change in the anticancer treatment plan due to COVID-19 was recorded in 148/463 patients with active cancer (32.0%). In patients with changes in systemic treatment plans (n = 146), treatment was delayed in 94 patients (in half of cases for > 1 month) and cancelled in 42 patients. The main reason for modifications in anti-cancer treatment was COVID-19 related complications (79.6%), followed by fear for/existence of anticancer treatment related toxicity (14.8%). Conclusions: Our nation-wide analysis in patients with solid cancer hospitalized with COVID-19 shows comparable 3-month mortality among patients who did and who did not receive anticancer treatment in the three months before COVID-19 diagnosis. Changes in anticancer treatment were very frequent in patients hospitalized with COVID-19. Further monitoring of the long-term impact of COVID-19-related changes to anticancer treatment plans is warranted.

Expected medium and long term impact of the COVID-19 outbreak in oncology

Background: The ongoing SARS-CoV-2 pandemic and ensuing coronavirus disease (COVID-19) is challenging cancer care and services worldwide. Methods: A 95 items survey was distributed worldwide by 20 oncologists from 10 of the most affected countries in order to evaluate the impact on organization of oncological care. Results: 109 representatives from oncology centers in 18 countries (62.4% academic hospitals) filled out the survey (June 17 – July 14, 2020). A swab or gargle test is systematically performed before day care unit or overnight stay admissions in 27.5% and 58.7% of the centers, respectively. A local registry (64.2%) and systematic tracing (77.1%) of infected patients was organized in many centers. Treatment modalities mostly affected by the pandemic (cancellation/delay) were surgery (44.1%) and chemotherapy (25.7%). Earlier cessation of palliative treatment was observed in 32.1% of centers, and 64.2 % of participants agree that under-treatment is a major concern. At the pandemic peak, teleconsultations were performed for follow-up (94.5%), for oral therapy (92.7%), but also for patients receiving immunotherapy (57.8%) or chemotherapy (55%). Approximately 82% of participants estimate that they will continue to use telemedicine. Most participants reported more frequent use of virtual tumor boards (82%) and oncological team meetings (92%), but 45% disagree that virtual meetings are an acceptable alternative to live international meetings. Although 60.9% report reduced clinical activity during the pandemic peak, only 28.4% had an increased scientific activity. Only 18% of participants estimate that their well-being will not recover to previous levels by the end of the year;63% indicate easily accessible psychological support for caregivers, but only 10% used or planned to use it. All clinical trial activities are or will soon be reactivated in 72.5% of the centers. Major study protocol violations/deviations were observed in 27.5% and significant reductions of clinical trial activities are expected by 37% of centers this year. Conclusions: COVID-19 has a major impact on organization of patient care, well-being of caregivers, continued medical education and clinical trial activities in oncology.
