Trends in the stage distribution of colorectal cancer during the COVID-19 pandemic in Japan: a nationwide hospital-claims data analysis.

ABSTRACT:

Background

The COVID-19 pandemic has affected cancer care. The aim of this study was to clarify the trend of colorectal cancer (CRC) stage distribution in Japan during the COVID-19 pandemic.

Methods

In this retrospective study, we used an inpatient medical claims database established at approximately 400 acute care hospitals. From the database, we searched patients who were identified as having the main disease (using ICD-10codes [C18.0-C20]) between January 2018 and December 2020.

Results

We analyzed 99,992 CRC patients. Logistic regression analysis, including the interaction t
