Delayed care for patients with newly diagnosed cancer due to COVID-19 and estimated impact on cancer mortality in France.

BACKGROUND: The impact of the first coronavirus disease 2019 (COVID-19) wave on cancer patient management was measured within the nationwide network of the Unicancer comprehensive cancer centers in France. PATIENTS AND METHODS: The number of patients diagnosed and treated within 17 of the 18 Unicancer centers was collected in 2020 and compared with that during the same periods between 2016 and 2019. Unicancer centers treat close to 20% of cancer patients in France yearly. The reduction in the number of patients attending the Unicancer centers was analyzed per regions and cancer types. The impact of delayed care on cancer-related deaths was calculated based on different hypotheses. RESULTS: A 6.8% decrease in patients managed within Unicancer in the first 7 months of 2020 versus 2019 was observed. This reduction reached 21% during April and May, and was not compensated in June and July, nor later until November 2020. This reduction was observed only for newly diagnosed patients, while the clinical activity for previously diagnosed patients increased by 4% similar to previous years. The reduction was more pronounced in women, in breast and prostate cancers, and for patients without metastasis. Using an estimated hazard ratio of 1.06 per month of delay in diagnosis and treatment of new patients, we calculated that the delays observed in the 5-month period from March to July 2020 may result in an excess mortality due to cancer of 1000-6000 patients in coming years. CONCLUSIONS: In this study, the delays in cancer patient management were observed only for newly diagnosed patients, more frequently in women, for breast cancer, prostate cancer, and nonmetastatic cancers. These delays may result is an excess risk of cancer-related deaths in the coming years.

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.
