Impact of COVID-19 pandemic on outpatient visit volume in cancer patients: Results of COMETA multicenter retrospective observational study.

Objective: To evaluate the impact of the COVID-19 pandemic on first and follow-up visits for cancer outpatients. Methods: This is a multicenter retrospective observational study involving three Comprehensive Cancer Care Centers (CCCCs): IFO, including IRE and ISG in Rome, AUSL-IRCCS of Reggio Emilia, and IRCCS Giovanni Paolo II in Bari) and one oncology department in a Community Hospital (Saint'Andrea Hospital, Rome). From 1 January 2020 and 31 December 2021, we evaluated the volume of outpatient consultations (first visits and follow-up), comparing them with the pre-pandemic year (2019). Results were analyzed by quarter according to the Rt (real-time indicator used to assess the evolution of the pandemic). IFO and IRCCS Giovanni Paolo II were "COVID-free" while AUSL-IRCCS RE was a "COVID-mixed" Institute. Depending on the Rt, Sain't Andrea Hospital experienced a "swinging" organizational pathway (COVID-free/ COVID-mixed). Results: Regarding the "first appointments", in 2020 the healthcare facilities operating in the North and Center of Italy showed a downward trend. In 2021, only AUSL-IRCCS RE showed an upward trend. Regarding the "follow-up", only AUSL IRCCS RE showed a slight up-trend in 2020. In 2021, IFO showed an increasing trend, while S. Andrea Hospital showed a negative plateau. Surprisingly, IRCCS Giovanni Paolo II in Bari showed an uptrend for both first appointment and follow-ups during pandemic and late pandemic except for the fourth quarter of 2021. Conclusions: During the first pandemic wave, no significant difference was observed amongst COVID-free and COVID-mixed Institutes and between CCCCs and a Community Hospital. In 2021 ("late pandemic year"), it has been more convenient to organize COVID-mixed pathway in the CCCCs rather than to keep the Institutions COVID-free. A swinging modality in the Community Hospital did not offer positive results in term of visit volumes. Our study about the impact of COVID-19 pandemic on visit volume in cancer outpatients may help health systems to optimize the post-pandemic use of resources and improve healthcare policies.

Coronavirus Disease 2019: A Brief Review of the Clinical Manifestations and Pathogenesis to the Novel Management Approaches and Treatments.

The recent outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) or coronavirus disease 2019 (COVID-19) in China, which spread to the rest of the world, led the World Health Organization to classify it as a global pandemic. COVID-19 belongs to the Bettacoronavirus genus of the Coronaviridae family, and it mainly spreads through the respiratory tract. Studies have now confirmed a human-to-human transmission as the primary pathway of spread. COVID-19 patients with a history of diseases such as respiratory system diseases, immune deficiency, diabetes, cardiovascular disease, and cancer are prone to adverse events (admission to the intensive care unit requiring invasive ventilation or even death). The current focus has been on the development of novel therapeutics, including antivirals, monoclonal antibodies, and vaccines. However, although there is undoubtedly an urgent need to identify effective treatment options against infection with COVID-19, it is equally important to clarify management protocols for the other significant diseases from which these patients may suffer, including cancer. This review summarizes the current evidence regarding the epidemiology, pathogenesis, and management of patients with COVID-19. It also aims to provide the reader with insights into COVID-19 in pregnant patients and those with cancer, outlining necessary precautions relevant to cancer patients. Finally, we provide the available evidence on the latest potent antiviral drugs and vaccines of COVID-19 and the ongoing drug trials.

Lights and Shadows on Managing Immune Checkpoint Inhibitors in Oncology during the COVID-19 Era.

Since the start of the global spread of coronavirus disease (COVID-19) pandemic, cancer patients were identified as a specifically susceptible subgroup of the patient population. Several reports have shown that cancer patients have an increased risk of both contracting the infection and of experiencing a more severe disease course, with a rapidly evolving picture associated with higher mortality. The assumption of cancer patients as "COVID-19 vulnerable" has led, irretrievably, to profound changes in the decision making of oncological treatments. Potential justifications for such concerns encompass the cancer-dependent suppression of the immune response, as well as the influence of administration of systemic anticancer treatments, including chemotherapy and immunotherapy. Nevertheless, to date, it is not clear whether the use of immune checkpoint inhibitors (ICIs) in cancer patients is safe, given their modulating effects on the immune system, or that they may rather conceal detrimental consequences. Theoretically, on the one hand, ICIs may enhance the immunological control of viral infections through their immunostimulating mechanisms; on the other hand, they could contribute to the hyper-inflammatory phase of COVID-19, worsening its clinical outcomes. In this study, we report the foremost clinical observations on the safety of ICI administration in cancer patients affected by COVID-19.
