We included patients with malignant and in situ neoplasms reported by pathology departments with consistent reporting. We calculated the number of incident cases during the COVID-19 pandemic and the pre-pandemic period with 95% confidence intervals (CI) with Bonferroni correction (\u03b1\u2009=\u20090.0018) based on a Poisson approach.

Incident malignant neoplasms dropped from 42,857 cases in the pre-pandemic period to 39,980 cases in the pandemic period (\u2212\u00a06.7%; 95% CI \u2212\u00a08.7%, \u2212\u00a04.7%). Reductions were higher for colon, rectum, skin\/melanoma as well as liver (&gt;\u200910.0% reduction) and less for breast cancer (4.9% reduction). No case reductions were observed for pancreas, esophagus, ovary, and cervix. Percent changes were largest for April 2020 (\u2212\u00a020.9%; 95% CI \u2212\u00a024.7%, \u2212\u00a016.8%) and January 2021 (\u2212\u00a025.2%; 95% CI \u2212\u00a028.8%, \u2212\u00a021.5%) compared to the previous year.
