Abstract

The coronavirus disease 2019 pandemic substantially impacted the delivery of cancer services and programs. Here we reviewed and synthesized the global scale and impact of pandemic-related delays and disruptions on cancer services, including diagnosis, diagnostic procedures, screening, treatment and supportive and palliative care. Based on data from 245 articles in 46 countries, we observed declines in the number of cancer screening participation (39.0%), diagnoses (23.0%), diagnostic procedures (24.0%) and treatment (28.0%), ranging from a 15.0% decline for radiotherapy to a 35.0% decline for systemic treatment during the pandemic compared to during the prepandemic period. Medium-human development index (HDI) category countries experienced greater reductions than high- and very-high-HDI countries. Missing data from low-HDI countries emphasize the need for increased investments in cancer surveillance and research in these settings. PROSPERO registration: CRD42022301816
