Different impacts of cancer types on cancer screening during COVID-19 pandemic in Taiwan

Impact of COVID-19 on cancer screening: a global perspective

“…In studies conducted in Canada, the United States, Brazil, France, Qatar, Taiwan, and Belgium, COVID-19 had a dramatic impact on mammography and/or MRI of the breast (À10 to À100%) [11, 14,15,16 ,34-37,40,43,44,46]. A significant drop in cancer screening computed tomography imaging in the United States (À49 to À81.7%) [32,37] ], and oral cancer in Taiwan (À50%) [43]. Cancer screening rates were impacted according to the prevalence of COVID-19 in the respective countries, poorly controlled COVID-19 infection rates, or the preparedness of the healthcare systems in dealing with crises such as the pandemic.…”

“…A significant drop in cancer screening computed tomography imaging in the United States (−49 to −81.7%) [ 32 , 37 ] and diagnostic radiology rates (−16%) was observed in Switzerland [ 17 ]. Reductions in cancer screening were reported for cervical cancer (−7.5 to −90%) in Canada, the United States, Brazil, France, Taiwan, Belgium, and 17 selected low- and middle-income countries (LMICs) [ 19 ▪ , 21 ▪ – 23 ▪ , 30 ▪▪ , 33 , 35 ▪ , 36 , 38 – 40 , 43 , 46 ]. A significant drop in digestive endoscopies (−19 to −29%) was reported in Lithuania and France [ 17 , 39 ].…”

“…A significant drop in digestive endoscopies (−19 to −29%) was reported in Lithuania and France [ 17 , 39 ]. Reductions in colon cancer screening (−8.1 to −95%) were registered in Canada, the United States, France, Belgium, Qatar, and 17 selected LMICs [ 14 , 15 , 16 ▪ , 23 ▪ , 25 , 30 ▪▪ , 33 , 35 ▪ , 36 – 39 , 43 , 44 ].

“…LCS rates fell in Canada, the United States, Ireland, and 17 selected LMICs (−21 to −44.6%) [ 11 , 24 , 30 ▪▪ ]. A significant reduction in prostate cancer screening rates (−63.4%) was reported in the United States [ 16 ▪ ], and oral cancer in Taiwan (−50%) [ 43 ]. Cancer screening rates were impacted according to the prevalence of COVID-19 in the respective countries, poorly controlled COVID-19 infection rates, or the preparedness of the healthcare systems in dealing with crises such as the pandemic.…”
