Background: Patients with cancer might be at an increased risk of infection with COVID-19 and a more severe disease course. However, different tumor types have differing susceptibility to the infection and COVID-19 phenotypes. Thus, the risk and prevalence of COVID-19 is not uniform across the different tumor types. Here, we performed a meta-analysis to estimate the risk and prevalence of COVID-19 infection in colorectal cancer (CRC) patients. Methods: A comprehensive literature search was performed up to July 25, 2020, thorough PubMed, Web of Science, Scopus, Google Scholar, CNKI, CBM, China Science, Wan Fang, and SciELO databases. The risk of COVID-19 infection in CRC patients was performed based on the odds ratios (ORs) and 95% confidence interval (95% CI). Results: A total of six studies with 204 different cancer patients with COVID-19 and 92 CRC infected patients with COVID-19 were selected. Our results showed that the prevalence of COVID-19 infection in CRC patients was 45.1% in the global population. The pooled data showed that there is no a significant risk of infection with COVID-19 in CRC patients in the global population (OR = 0.261, 95% CI 0.099–0.533, p = 0.082). However, when subgroup analysis was performed based on country of origin, we found a significant correlation in Chinese CRC patients (OR = 0.221, 95% CI 0.146–0.319, p ≤ 0.001). Conclusions: This study results revealed that Chinese CRC patients harbored a higher risk of COVID-19 infection. However, more multicenter, larger sample sizes and high-quality studies are required to verify this meta-analysis result. [ABSTRACT FROM AUTHOR] |
