Supplementary Material for: Impact of the COVID-19 Pandemic on Surgical Oncology in Europe: Results of a European Survey

<b><i>Background:</i></b> The first COVID-19 pandemic wave hit most of the health-care systems worldwide. The present survey aimed to provide a European overview on the COVID-19 impact on surgical oncology. <b><i>Methods:</i></b> This anonymous online survey was accessible from April 24 to May 11, 2020, for surgeons (<i>n</i> = 298) who were contacted by the surgical society European Digestive Surgery. The survey was completed by 88 surgeons (29.2%) from 69 different departments. The responses per department were evaluated. <b><i>Results:</i></b> Of the departments, 88.4% (<i>n</i> = 61/69) reported a lower volume of patients in the outpatient clinic; 69.1% (<i>n</i> = 47/68) and 75.0% (<i>n</i> = 51/68) reported a reduction in hospital bed and the operating room capacity, respectively. As a result, the participants reported an average reduction of 29.3% for all types of oncological resections surveyed in this questionnaire. The strongest reduction was observed for oncological resections of hepato-pancreatico-biliary (HPB) cancers. Of the interviewed surgeons, 68.7% (<i>n</i> = 46/67) agreed that survival outcomes will be negatively impacted by the pandemic. <b><i>Conclusion:</i></b> The first COVID-19 pandemic wave had a significant impact on surgical oncology in Europe. The surveyed surgeons expect an increase in the number of unresectable cancers as well as poorer survival outcomes due to cancellations of follow-ups and postponements of surgeries.

<b><i>研究背景:</i></b> 新型冠状病毒肺炎（COVID-19）疫情的第一波冲击波及全球绝大多数医疗系统。本调查旨在对COVID-19疫情对欧洲外科肿瘤学领域的影响进行全景式梳理。<b><i>研究方法:</i></b> 本研究采用匿名在线问卷形式，于2020年4月24日至5月11日面向欧洲消化外科协会（European Digestive Surgery）联络的298名外科医师开放征集。最终共有来自69个不同科室的88名外科医师完成问卷，有效回收率为29.2%。本研究对各科室的回收结果进行了统计分析。<b><i>研究结果:</i></b> 结果显示，88.4%的科室（61/69）报告门诊接诊量有所下降；69.1%（47/68）和75.0%（51/68）的科室分别报告住院床位及手术室接诊能力出现缩减。受此影响，受访医师报告本次调研覆盖的各类肿瘤切除手术量平均下降29.3%。其中肝胰胆（HPB）恶性肿瘤切除术量的下降幅度最为显著。68.7%的受访外科医师（46/67）认为，本次疫情将对肿瘤患者的生存结局产生负面影响。<b><i>研究结论:</i></b> 综上，COVID-19疫情第一波冲击对欧洲外科肿瘤学领域造成了显著影响。受访外科医师预计，由于随访工作取消及手术延期，欧洲不可切除性肿瘤病例数将有所增加，患者的整体生存结局也将进一步恶化。
