Pandemic disruptions to health care worsened cancer survival, study suggests

More than 1 million U.S. cancer patients diagnosed in 2020-21 had lower one-year survival, possibly due to pandemic-related care disruptions, researchers said.

  • Thursday's JAMA Oncology report, funded by federal grants, found worse one-year survival for cancer patients diagnosed in 2020 and 2021 based on U.S. national cancer-registry data.
  • Due to postponed screenings and strained hospitals, investigators found COVID-19 disruptions to colonoscopies, mammograms, and lung scans likely reduced access and timeliness of treatment.
  • More than 1 million people were diagnosed in 2020 and 2021, about 144,000 died within one year, and researchers estimated about 17,400 excess deaths relative to 2015–2019 expectations.
  • The study's authors cautioned they could not definitively identify causal drivers, noting further research will be needed to see if impacts are lasting, as researchers filtered out COVID-19 deaths to isolate other contributors.
  • Earlier research found overall U.S. cancer death rates continued to decline during the pandemic, while the federally funded study is important for ongoing evaluation of pandemic effects, Recinda Sherman said.
