COVID-19 Pandemic Disrupts Cancer Care and Outcomes in Alberta, Canada
Researchers at the University of Calgary have found that the COVID-19 pandemic significantly affected cancer care and outcomes in Alberta, Canada. A new study published in the Canadian Medical Association Journal (CMAJ) evaluated the impact of the state of emergency period during the pandemic on cancer diagnoses, stage at diagnosis, and 1-year survival. The study found significant reductions in diagnoses of breast, prostate, and colorectal cancers, as well as melanoma, and lower 1-year survival rates for patients diagnosed with colorectal, non-Hodgkin lymphoma, and uterine cancers in 2020 compared to 2018.
Key Takeaways:
- The COVID-19 pandemic significantly affected cancer diagnoses and outcomes in Alberta, Canada, with significant reductions in diagnoses of breast, prostate, and colorectal cancers, as well as melanoma.
- The study found that the reductions in cancer diagnoses largely occurred among early-stage rather than late-stage diagnoses.
- Patients who received a diagnosis of colorectal cancer, non-Hodgkin lymphoma, and uterine cancer in 2020 had lower 1-year survival than those diagnosed in 2018.
- The results suggest that health care disruptions during the pandemic in Alberta considerably affected cancer outcomes.
- Additional system capacity may be needed to mitigate future impact, particularly for early-stage cancers and those with organized screening programs.
Statistics:
- Significant reductions in diagnoses of breast cancer (incidence rate ratio [IRR] 0.67, 95% confidence interval [CI] 0.59-0.76).
- Significant reductions in diagnoses of prostate cancer (IRR 0.64, 95% CI 0.56-0.73).
- Significant reductions in diagnoses of colorectal cancer (IRR 0.64, 95% CI 0.56-0.74).
- Significant reductions in diagnoses of melanoma (IRR 0.57, 95% CI 0.47-0.69).
- Lower 1-year survival rates for patients diagnosed with colorectal cancer (18.1%), non-Hodgkin lymphoma (21.1%), and uterine cancer (23.1%) in 2020 compared to 2018.
