Abstract: Abstract Background Suspension of cancer screening and treatment programs were instituted to preserve medical resources and protect vulnerable populations. This research aims to investigate the implications of COVID-19 on cancer management and clinical outcomes for patients with prostate and colorectal cancer in Canada. Methods We examined hospital cancer screening, diagnosis, treatment, length of stay, and mortality data among prostate and colorectal cancer patients between April 2017 and March 2021. Baseline trends were established with data between April 2017 and March 2020 for comparison with data collected between April 2020 and March 2021. Scenario analyses were performed to assess the incremental capacity requirements needed to restore hospital cancer care capacities to the pre-pandemic levels. Results For prostate cancer, A 12% decrease in diagnoses and 5.3% decrease in treatment activities were observed during COVID-19 between April 2020 and March 2021. Similarly, a 43% reduction in colonoscopies, 11% decrease in diagnoses and 10% decrease in treatment activities were observed for colorectal cancers. An estimated 1,438 prostate and 2,494 colorectal cancer cases were undiagnosed, resulting in a total of 620 and 1,487 unperformed treatment activities for prostate and colorectal cancers, respectively, across nine provinces in Canada. To clear the backlogs of unperformed treatment procedures will require an estimated 3%-6% monthly capacity increase over the next 6 months. Interpretation. A concerted effort from all stakeholders is required to immediately ameliorate the backlogs of cancer detection and treatment activities. Mitigation measures should be implemented to minimize future interruptions to cancer care in Canada.
