During the COVID-19 pandemic, many colorectal cancer-related procedures were suspended, with unclear implications for colorectal cancer mortality. In this study, van den Puttelaar and colleagues used observed data and simulation modeling to estimate the impact on colorectal cancer outcomes, clinical resources, and associated tradeoffs, for longer versus shorter recovery periods to catch up procedures. The authors estimate that the disruptions may cause 4,200 to 14,400 excess colorectal cancer deaths in the US in the next 20 years, depending on the assumed extent of disruption, length of recovery period, and resources used. These estimates may help inform strategies to mitigate the broader impact of the COVID-19 pandemic or future crises.
Christopher and colleagues used a data-driven approach to identify exercise trajectories over the adult life course and examined how these trajectories were associated with colon cancer risk within the NIH-AARP Diet and Health Study. Adults maintaining moderate-to-high amounts of exercise consistently...
