Impact of COVID-19 Pandemic on Oncological Surgery Activities: A Retrospective Study from a Southern Italian Region.

(1) Background: The pandemic had a strong impact on healthcare for other diseases, the so-called collateral damage. This situation heavily impacted the health care system, causing a deferment of surgical admissions. This situation had an immediate and long-term impact on millions of patients with surgical diseases all over the world. The objective of this study was to evaluate the incidence of hospitalizations for colorectal and breast cancers in an Italian region in the year 2020 and compare it with the years 2018−2019. (2) Methods: This retrospective study was performed in the region of Abruzzo, Italy. Monthly number of hospitalizations in the year 2020 was compared with a control period consisting of the average of admissions that occurred in the years 2018−2019 using Poisson regression. (3) Results: A reduction in hospital admissions for all diseases considered was found. In particular, compared with years 2018−2019, admissions for colorectal cancer were 35.71% lower (HRR 0.915; p < 0.001), and admissions for breast cancer were 10.36% lower (HRR 0.895; p < 0.001) (4) Conclusions: The results of this study showed the decrease of admissions for elective oncological surgery during pandemic, suggesting the need of strategic measures to face the burden of future years’ hospitalizations.
