The median age was 43 years (range, 29-68 years), and the majority were male (62%). At the time of the survey, nearly all participants self-reported an outbreak in their country (99.7%). Personal protective equipment was available to all participants, of which surgical mask was the most common (n = 308; 90%). Telemedicine, in the form of phone or video encounters, was common and implemented by 80% (n = 273). Testing patients with cancer for COVID-19 via reverse transcriptase polymerase chain reaction before systemic treatment was not routinely implemented: 58% reported no routine testing, 39% performed testing in selected patients, and 3% performed systematic testing in all patients. The most significant factors influencing an oncologist\u2019s decision making regarding choice of systemic therapy included patient age and comorbidities (81% and 92%, respectively). Although hormonal treatments and tyrosine kinase inhibitors were considered to be relatively safe, cytotoxic chemotherapy and immune therapies were perceived as being less safe or unsafe by participants. The vast majority of participants stated that during the pandemic they would use less chemotherapy, immune checkpoint inhibitors, and steroids. Although treatment in neoadjuvant, adjuvant, and first-line metastatic disease was less affected, most of the participants stated that they would be more hesitant to recommend second- or third-line therapies in metastatic disease.<\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSION<\/jats:title><jats:p>Decision making by oncologists has been significantly influenced by the ongoing COVID-19 pandemic.<\/jats:p><\/jats:sec>","DOI":"10.1200\/go.20.00300","type":"journal-article","created":{"date-parts":[[2020,8,5]],"date-time":"2020-08-05T19:59:34Z","timestamp":1596657574000},"page":"1248-1257","update-policy":"https:\/\/doi.org\/10.1200\/crossmark","source":"Crossref","is-referenced-by-count":37,"title":["Survey of the Impact of COVID-19 on Oncologists\u2019 Decision Making in Cancer"],"prefix":"10.1200","author":[{"given":"Y\u00fcksel","family":"\u00dcr\u00fcn","sequence":"first","affiliation":[{"name":"Department of Medical Oncology, Ankara University School of Medicine, Ankara, Turkey"},{"name":"Ankara University Cancer Research Institute, Ankara, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Syed A.","family":"Hussain","sequence":"additional","affiliation":[{"name":"Academic Unit of Oncology, University of Sheffield, Sheffield, United Kingdom"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ziad","family":"Bakouny","sequence":"additional","affiliation":[{"name":"Department of Medical Oncology, Lank Center for Genitourinary Oncology, Dana-Farber Cancer Institute, Harvard Medical School, Boston, MA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel","family":"Castellano","sequence":"additional","affiliation":[{"name":"Medical Oncology Department, Hospital Universitario 12 de Octubre, Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Saadettin","family":"K\u0131l\u0131\u00e7kap","sequence":"additional","affiliation":[{"name":"Hacettepe University Cancer Institute, Ankara, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gilberto","family":"Morgan","sequence":"additional","affiliation":[{"name":"Department of Medical and Radiation Oncology, Sk\u00e5ne University Hospital, Lund, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rana R.","family":"Mckay","sequence":"additional","affiliation":[{"name":"Moores Cancer Center, University of California San Diego, La Jolla, CA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kevin","family":"Pels","sequence":"additional","affiliation":[{"name":"Department of Medical Oncology, Lank Center for Genitourinary Oncology, Dana-Farber Cancer Institute, Harvard Medical School, Boston, MA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrew","family":"Schmidt","sequence":"additional","affiliation":[{"name":"Department of Medical Oncology, Lank Center for Genitourinary Oncology, Dana-Farber Cancer Institute, Harvard Medical School, Boston, MA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Deborah B.","family":"Doroshow","sequence":"additional","affiliation":[{"name":"Tisch Cancer Institute, Icahn School of Medicine at Mount Sinai, New York, NY"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"F\u00e1bio","family":"Sch\u00fctz","sequence":"additional","affiliation":[{"name":"Clinical Oncology Department, BP - A Benefic\u00eancia Portuguesa de S\u00e3o Paulo, S\u00e3o Paulo, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Laurence","family":"Albiges","sequence":"additional","affiliation":[{"name":"Department of Medical Oncology, Gustave Roussy Cancer Campus, Villejuif, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gilberto","family":"Lopes","sequence":"additional","affiliation":[{"name":"Division of Hematology and Medical Oncology, Department of Medicine, Miller School of Medicine, University of Miami, Sylvester Comprehensive Cancer Center, Miami, FL"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"James W.
