Background The COVID-19 pandemic has resulted in a significant decrease in the number of elective cancer operations performed. Cancer patients are felt to be a high-risk group for COVID-19, and therefore, concerns have been raised regarding the safety of operating during this time; however, the potential risk of cancer progression if untreated must also be considered. The aim of this study was therefore to identify the incidence of COVID-19 postoperatively in patients undergoing elective cancer surgery of all types. Methods Data were collected on all patients who had an elective therapeutic cancer operation in a single large district general hospital, where standard COVID-19 precautions were in place, between 01/02/2020 and 27/4/2020, Follow-up was for a minimum of 2 weeks post-discharge. The primary outcome was the incidence of COVID-19 during the follow-up period. Results A total of 621 elective cancer surgeries, from a range of specialities, were performed during the study period, with 55% (n = 341) being done as day cases. None of the patients were positive for COVID-19 post-operatively using reverse transcriptase polymerase chain reaction testing. Conclusions The risk of COVID-19 following elective cancer surgery in this group of high-risk patients appears to be minimal in this study. With further precautions being introduced to reduce the risk of transmission of COVID-19, an increase in the rate of elective cancer surgery should be a current priority for all hospitals where possible.
