Abstract Introduction: A better understanding of the reality for cancer patients during COVID-19 will help us readapt current predication models. To further inform future clinical guidelines, we need a deep dive into rich data sources from apex Cancer Centres. We report on the outcomes of cancer patients receiving radical surgery between March-September 2020 (as well as 2019) in the European Institute of Oncology (EIO) in Milan and the South East London Cancer Alliance (SELCA). Methods: IEO is one of the largest cancer hospitals in Italy. SELCA includes 3 major hospital trust, treating about 8,000 new cancer patients per annum. Both institutions implemented a COVID-19 minimal pathway, whereby patients were required to shield for 14 days prior to admission and were swabbed for COVID-19 within 3 days of surgery. Positive patients had surgery deferred until a negative swab. Surgical outcomes assessed were: ASA grade, surgery time, theatre time, ICU stay&amp;gt;24h, pneumonia, length of stay (LOS), and admissions. For COVID-19, we focused on infection rate and mortality. Results: At IEO the number of radical surgeries (270 for gynaecological, 339 for head and neck, 377 for thoracic, and 491 for urological cancers) declined by 6% as compared to the same period in 2019 (n=1477 vs 1560). The main decline was observed for thoracic surgery (377 vs 460, i.e. -18%). Age, sex, SES, ethnicity, comorbidities, and performance status were all comparable between both periods (e.g. 58% male, 38% aged 70+, 48% high SES, 15% with existing cardiovascular diseases). Readmissions were required for 39%, and &amp;lt;1% (n=9) developed COVID-19, of which only 1 had severe disease and died. 11 died of other causes during follow-up (1%). At SELCA, the number of radical surgeries (321 for breast, 129 for colorectal, 114 for gynaecological, 152 for head and neck, 92 for liver, 56 for plastics/skin, 305 for thoracic, 72 for upper gastrointestinal, and 312 for urology) declined by 29% (n=1553 vs 2182). Even though a different geographical setting, characteristics were fairly comparable with the IEO: 58% males, 30% aged 70+, 34% high SES, 16% with existing cardiovascular diseases. Readmissions were required for 22%, &amp;lt;1% (n=7) developed COVID-19, and none died from it. 19 died of other causes within 30 days (1%). Conclusion: Milan and London were both at the epicentre of the first COVID-19 wave. Whilst a decline in number of surgeries was observed, the implemented COVID-19 minimal pathways have shown to be safe for cancer patients requiring radical treatment, with limited complications and almost no COVID-19 infections.
