INTRODUCTION Coronavirus Disease 2019 disrupted cancer-related care in early 2020. METHODS We used population-based cancer registry data to estimate incidence and mortality rates of gastrointestinal cancers between 2016 and 2020. RESULTS Incidence rates were unchanged from 2016 to 2019 but decreased in 2020, with the largest declines for colorectal cancer (rate ratio [RR] 0.88; 95% confidence interval [CI] 0.87-0.90) and hepatocellular carcinoma (RR 0.85; 95% CI 0.82-0.88). Mortality rates of colorectal cancer (RR 1.06; 95% CI 1.04-1.08) and esophageal adenocarcinoma (RR 1.06; 95% CI 1.00-1.13) increased in 2020. DISCUSSION Incidence and mortality rates of gastrointestinal cancers may increase in the future given pandemic-related delays in 2020.

2020 年与疫情相关的胃肠道癌症发病率和死亡率变化。

简介 2019 年冠状病毒病扰乱了 2020 年初的癌症相关护理。方法我们使用基于人群的癌症登记数据来估计 2016 年至 2020 年间胃肠道癌症的发病率和死亡率。结果 2016 年至 2019 年发病率没有变化，但 2020 年有所下降，降幅最大的是结直肠癌（比率 [RR] 0.88；95% 置信区间 [CI] 0.87-0.90）和肝细胞癌（RR 0.85；95% CI 0.82-0.88）。2020 年，结直肠癌（RR 1.06；95% CI 1.04-1.08）和食管腺癌（RR 1.06；95% CI 1.00-1.13）的死亡率有所增加。讨论 鉴于大流行，未来胃肠道癌症的发病率和死亡率可能会增加。 2020 年相关延误。
