The influence of these effects on diagnosis and treatment of cancer in Germany is largely unknown.<\/jats:p><jats:p><jats:bold>Methods:<\/jats:bold> To evaluate the effect of the first wave of the COVID-19 pandemic on tumor board presentations in a high-volume tertiary referral center (the German Comprehensive Cancer Center NCT\/UCC Dresden), we compared the number of presentations of gastrointestinal tumors stratified by tumor entity, tumor stage, and treatment intention during the pandemic to the respective data from previous years.<\/jats:p><jats:p><jats:bold>Results:<\/jats:bold> The number of presentations decreased by 3.2% (95% CI \u22128.8, 2.7) during the COVID year 2020 compared with the pre-COVID year 2019. During the first shutdown, March\u2013May 2020, the total number of presentations was 9.4% (\u221218.7, 1) less than during March\u2013May 2019. This decrease was significant for curable cases of esophageal cancer [<jats:italic>N<\/jats:italic> = 37, 25.5% (\u221241.8, \u22124.4)] and colon cancer [<jats:italic>N<\/jats:italic> = 36, 17.5% (\u221232.6, 1.1)] as well as for all cases of biliary tract cancer [<jats:italic>N<\/jats:italic> = 26, 50% (\u221269.9, \u221215)] during the first shutdown from March 2020 to May 2020.<\/jats:p><jats:p><jats:bold>Conclusion:<\/jats:bold> The impact of the COVID-19 pandemic on the presentation of oncological patients in a CCC in Germany was considerable and should be taken into account when making decisions regarding future pandemics.<\/jats:p>","DOI":"10.3389\/fpubh.2021.750479","type":"journal-article","created":{"date-parts":[[2021,11,30]],"date-time":"2021-11-30T14:17:21Z","timestamp":1638281841000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":10,"title":["Influence of the First Wave of the COVID-19 Pandemic on Cancer Care in a German Comprehensive Cancer Center"],"prefix":"10.3389","volume":"9","author":[{"given":"Johanna","family":"Kirchberg","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anke","family":"Rentsch","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anna","family":"Klimova","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vasyl","family":"Vovk","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sebastian","family":"Hempel","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gunnar","family":"Folprecht","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mechthild","family":"Krause","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Verena","family":"Plodeck","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thilo","family":"Welsch","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J\u00fcrgen","family":"Weitz","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Johannes","family":"Fritzmann","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2021,11,23]]},"reference":[{"key":"B1","first-page":"580","article-title":"Gesetz zum Ausgleich COVID-19 bedingter finanzieller Belastungen der Krankenh\u00e4user und weiterer Gesundheitseinrichtungen (COVID-19-Krankenhausentlastungsgesetz)","volume":"14","author":"Deutscher","year":"2020","journal-title":"Bundesgesetzblatt Teil I"},{"key":"B2","first-page":"2397","article-title":"Gesetz zum Schutz der Bev\u00f6lkerung bei einer epidemischen Lage nationaler Tragweite","volume":"14","author":"Deutscher","year":"2020","journal-title":"Bundesgesetzblatt.
