Incidence of rare cancers during the COVID-19 pandemic: a US population-based study.

ABSTRACT:

Introduction

Recent media reporting has suggested an increase in the incidence of rare cancers in 2021 as a result of the COVID-19 pandemic, raising concern for possible carcinogenic effects of severe acute respiratory syndrome coronavirus 2 infection. We aimed to identify cancers that increased in incidence in the United States during 2021 compared with 2018-2019.

Methods

We analyzed data from Surveillance, Epidemiology, and End Results (SEER-22) using a systematic classification schema including rare cancers. We estimated age-standardized incidence rate ratios (aIRRs) comparing the year 2021 to 2018-2019 for 693 individual cancer types and highlight those with an aIRR > 1 based on a Bonferroni-corrected P-value threshold. Cancer types of particular interest included cholan
