CP3R is used to compare patterns of care and assess trends for which cancers?

• A. Lung and skin cancers
• B. Prostate and bladder cancers
• C. Brain and pancreatic cancers
• D. Breast and colorectal cancers

Answer: (D)

CP3R is a framework for measuring and comparing how cancer care is delivered and for tracking how that care changes over time. It works best when there are clear, widely used screening programs and standardized treatment pathways, so differences in practice can be reliably detected. Breast and colorectal cancers fit this well because they have established population screening (mammography for breast cancer and colonoscopy or other stool-based tests for colorectal cancer) and well-defined multidisciplinary treatment pathways. This combination makes it possible to compare patterns of care across regions or time periods—such as diagnostics timelines, access to surgery, use of adjuvant therapies, and alignment with guidelines—and to observe meaningful trends. Other cancers may lack uniform screening or have more variable treatment routes, which can make pattern comparisons less straightforward with this framework.
