Background: At the start of the COVID-19 pandemic, a plan for cancer management during a pandemic did not exist. It soon became clear that without proper planning, cancer outcomes would worsen. Cancer patients are at increased risk of COVID-19 infection, morbidity, and mortality. Health sectors internationally reduced or paused non-urgent cancer care to protect cancer patients from COVID-19. However, disproportionate delays in screening, diagnosis, and treatment can unduly impact cancer outcomes, and backlogs can further burden a strained health system. Tailored approaches to cancer management are required which balance health resource availability along with the risks of exposure and benefits of treatment. Australia's relatively low COVID-19 case numbers afforded Cancer Australia an opportunity to proactively plan for optimal cancer management during this, and future, pandemics. Methods: Cancer Australia's Cancer care in the time of COVID-19: A conceptual framework for the management of cancer during a pandemic (the framework) maps evidence-based cancer care considerations in relation to a health system's capacity across acute and recovery pandemic phases, in relation to steps of the cancer care pathway. The framework promotes infection control and resource prioritisation in the context of innovative care models, triaging approaches and individualised treatment plans, underpinned by effective communication and shared decision-making. Results: The framework supports health system planning and risk-stratified approaches to guide decision-making and improve cancer outcomes. Many aspects of cancer care are recommended to continue (to varying degrees) in most pandemic phases, with modifications or pauses in some aspects of care as the pandemic curve approaches or exceeds health system capacity. Principles of the framework were employed during the second wave of COVID-19 in the Australian state of Victoria, with continuation of cancer screening programs, diagnostic investigations, and treatments wherever it was safe to do so. This resulted in reductions in cancer services and treatment being relatively smaller than in the first wave. Conclusions: Cancer management in a pandemic is not a one-size-fits-all. Countries and jurisdictions need to tailor cancer care according to the risk of the health system becoming overwhelmed. The framework guides optimal cancer care to improve outcomes for people with cancer, while minimising COVID-19 infection. As further evidence becomes available from this pandemic or in future pandemics, this framework can be refined to inform ongoing and future pandemic health system planning.
