Abstract
The Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) associated disease (COVID-19) outbreak seriously challenges globally all health care systems and professionals. Expert projections estimate that despite social distancing and lockdown being practiced, we have yet to feel the full impact of COVID-19. In this manuscript we provide guidance to prepare for the impact of COVID-19 pandemic on breast cancer patients and advise on how to triage, prioritize and organize diagnostic procedures, surgical, radiation and medical treatments.

These agents are now considered the standard of care for this subtype of breast cancer but can be used in either 1st or 2nd line. During this pandemic, the decision to add a CDK 4/6 inhibitor to endocrine therapy should take into account the burden of metastatic disease, the pace of disease progression and the possibility of using these agents later in the course of the disease (situation variable in different countries).</p></list-item><list-item id="u0065"><label>•</label><p id="p0390">The addition of an mTOR inhibitor or a Pi3KCA inhibitor to endocrine therapy must also take into account their immunosuppressive effect and the risk of pneumonitis/interstitial lung disease and other serious side effects, as well as the lack of survival benefit seen so far from the use of these agents.

The significant psychological impact on oncological patients is compounded by multiple factors during the pandemic – knowledge that the individual is at higher risk of serious complication if infected by Covid-19, loneliness and isolation as a result of social distancing, and the underlying constant fear of the cancer. Loneliness is associated with higher risk of mortality in cancer patients<xref rid="bib34" ref-type="bibr"><sup>34</sup></xref><sup>,</sup><xref rid="bib35" ref-type="bibr"><sup>35</sup></xref>. Social distancing is known to have negative health consequences and increase risk for premature mortality during normal times<xref rid="bib36" ref-type="bibr"><sup>36</sup></xref>, but it also enhances patients’ feelings of uncertainty associated with their prognosis. It is now well documented that perceived uncertainty increases individual emotional distress and this in turn has negative effects on clinical outcomes in cancer patients<xref rid="bib37" ref-type="bibr"><sup>37</sup></xref><sup>,</sup><xref rid="bib38" ref-type="bibr"><sup>38</sup></xref>. Three main aspects explain such uncertainty: patients’ perception of the impact of social isolation and of the healthcare crisis to access the cancer center to continue treatments; the risk of being infected when accessing the cancer center; and the need to change daily habits, especially those recommended by health professionals as affecting well-being and clinical outcomes, such as physical activity. The need to be isolated to contain the epidemics is a stark contrast to what is normally recommended for cancer patients including the importance of outdoor physical exercise and of maximizing social supports.</p><p id="p0425">To deal with the increased risk of distress and psychological disorders and the obligation to adhere to social isolation, telemedicine has been used also by psychologists and psychiatrists to guarantee psychological individual and group support for patients while limiting visits to the cancer center. In order to propose the adequate support to patients, psychological status and associated contributing factors should be monitored at different time points of the care pathway. Hospital Anxiety and Depression Scale (HADS) is an easy to use questionnaire and has a good accuracy in assessing anxiety and depression in cancer patients<xref rid="bib39" ref-type="bibr"><sup>39</sup></xref>. Furthermore, even in presence of low levels of depression and anxiety it will be crucial to identify critical levels of intolerance of uncertainty and feelings of loneliness in order to implement interventions to decrease the risk of further distress and psychopathological complications.</p></sec></sec><sec id="sec2"><title>Conclusions</title><p id="p0430">In the context of the COVID-19 pandemic, we recommended that routine breast screening be suspended, and that patients with early and advanced breast cancer be treated as outpatients as much as possible at the nearest medical center. Exams and appointments of patients on follow-up or under adjuvant endocrine therapy should either be postponed or managed through telemedicine. Treatment should follow international guidelines, as much as possible, but efforts should be made to minimize the number of hospital visits. All treatment decisions should be taken in the context of a multidisciplinary tumour board, which may take place virtually. All treatment decision-making should balance risk and benefits of treatment in the context of the specific pandemic level, on a case by case discussion, always including patients’ preferences.</p></sec><sec id="sec3"><title>Disclosures of interest statement</title><p id="p0435">GC reports grants from Roche, advisory role for Daichii Sankyo, Astra Zeneca Macrogenics, BMS and Ellipsis, personal fees from MSD, Astra Zeneca, travel grants from Pfizer, personal fees from Daichii Sankyo, outside the submitted work;</p><p id="p0440">MJC, OG have no financial disclosures</p><p id="p0445">PP is a medical advisor for Sordina IORT Technologies spa</p><p id="p0450">GP reports no conflicts of interest</p><p id="p0455">KM reports no conflicts of interest</p><p id="p0460">NH receives funding via a National Breast Cancer Foundation (NBCF Australia) Breast Cancer Research Leadership Fellowship.</p><p id="p0465">OP reports no conflicts of interest</p><p id="p0470">ES reports honoraria: Amgen, AstraZeneca, Clinigen, Egis, Eli Lilly, Genomic Health, Novartis, Pfizer, Pierre Fabre, Roche, Sandoz, TLC Biopharmaceuticals.
