<p>The long-term impact of the coronavirus disease 2019 (COVID-19) pandemic on the disruption of gastrointestinal cancer diagnoses remains unclear. This study investigated the actual impact on esophagogastric cancer (EGC) and colorectal cancer (CRC) diagnoses up to the third year of the pandemic in Akita Prefecture, Japan, using population-based registry data. We collected data on the annual number of EGC and CRC diagnoses using a database from the collaborative Akita Prefecture hospital-based registration. The net number of cancers diagnosed in the first three years of the pandemic (2020-2022) were compared with those diagnosed in the three years before the pandemic (2017-2019). Changes in the proportion of cancer stage and initial treatment for diagnosed EGC and CRC after the pandemic were then compared. The total number of EGCs was 9.3% lower in the first three years of the pandemic than in the three years before, probably due to its long-term declining trend. The total number of CRCs in the first three years of the pandemic exceeded that in the three years before, suggesting successful recovery of the diagnostic procedure. The proportion of cancer stages and initial treatment for EGCs and CRCs remained largely unchanged after the onset of the pandemic. Based on the population-based registry data from the first three years of the pandemic, the disruption of gastrointestinal cancer diagnoses caused by the pandemic is settling down without any substantial disease progression, even in Akita Prefecture, the area with the highest incidence of cancer in all of Japan.</p>

<p>We recently reported the decrease in the number of gastrointestinal (GI) cancer diagnoses in 2020 due to disturbance of the healthcare system by the coronavirus disease 2019 (COVID-19) pandemic, using a hospital-based cancer registration system in Akita prefecture, Japan. In this study, we extended the research by showing the latest data (2021) on the number of cancers and examinations. Information on the occurrence and stage of esophageal, gastric, and colorectal cancers was collected from the same database. The number of GI examinations (cancer screening procedures and endoscopic examinations) was also investigated. Following the immediate decrease in the numbers of both GI examinations and GI cancer diagnoses in 2020, a rebound increase in the numbers of GI cancer diagnoses—especially colorectal cancers—was observed in 2021, resulting from an increased number of GI examinations i.e., the total number of colorectal cancers in 2021 increased by 9.0% and 6.8% in comparison to 2020 and pre-pandemic era, respectively. However, the rebound increase in 2021 was largely due to an increase in early-stage cancers, and there was no apparent trend toward the increased predominance of more advanced cancers. It therefore seems that we managed to escape from the worst-case scenario of disturbance of the healthcare system due to pandemic (i.e., an increase in the number of more advanced cancers due to delayed diagnoses). We need to continue to watch the trends in Akita prefecture, which has the highest rate of mortality from the 3 major GI cancers in Japan.</p>
