Measuring the impact of the COVID‐19 pandemic on colorectal cancer presentation: a retrospective comparative study

Backgrounds The Coronavirus disease 2019 (COVID‐19) pandemic provided challenges to surgical care in Australia. This study aimed to measure the potential impact of COVID‐19 on colorectal cancer presentation through surgical volume and cancer staging at a major tertiary referral hospital in the city of Sydney Australia. Methods A retrospective cohort study was performed using routinely collected data from consecutive colorectal cancer patients undergoing surgery during the COVID‐19 period (1 March 2020 to 1 October 2021) and compared with the pre‐COVID‐19 period (1 March 2018 to 1 October 2019). The main outcomes included patient demographics, surgical volume (including overall, elective and emergency) and cancer staging. Differences in outcomes between the two studied periods were compared using Pearson's chi‐squared test, Fisher test or t‐test. Results A total of 381 patients composed the COVID‐19 group (Mean age = 62.4 years) and 364 patients composed the pre‐COVID‐19 group (Mean age = 65.6 years; P
