The real-word impact of breast and colorectal cancer surgery during the {SARS}-{CoV}-2 pandemic

The postponing of screening and the health care system reorganization, due to the Covid-19 pandemic and lockdown, could led to a concerning decline in breast and colorectal cancer diagnoses. This monocentric retrospective analysis has compared the pre-Covid period (March 2019 to March 2020) to the Covid period (April 2020 to April 2021) in terms of screening programs, clinical, surgical and pathological. A total of 799 patients diagnosed with Breast Cancer (BC) and Colorectal Cancer (CRC) underwent surgery during the two periods. In FVG in 2020 a decrease in mammography screening of 17.1% has been registered compared to 2019; this reduction has been higher for CRC screening, which summed up to 24.5%. As far as BC is concerned, screening-detected tumours rose significantly from 18 to 28%, mastectomies decreased from 40 to 31% and advanced tumours treated surgically decreased from 12 to 6%. Concerning CRC, a significant increase in admissions through the Emergency Department has been registered in spite of a stable percentage of urgent surgery performed, proving that severely symptomatic patients have been treated adequately. Open surgery has significantly decreased, whereas the tumoral stage and complications have remained constant in the two periods. This study has proved that maintaining standards of care and validated protocols during emergency is the most adequate and winning strategy: impact on BC and CRC has been less important than expected. These results support the recommendations for immediate and rapid screening program resumption at operating speed, using prioritization strategies to make up for the diagnostic delays.
