The National Program of Cancer Registries uses which CS-derived stage?

The main idea here is that population-based cancer registries use a simplified, standardized stage derived from the Collaborative Stage data collection. This CS-derived stage is the Summary Stage, not the detailed AJCC TNM staging. NPCR adopts Summary Stage so data from all registries can be compared consistently across the country, using broad categories like localized, regional, and distant. AJCC staging provides detailed clinical TNM information, but it’s more complex and not the CS-derived stage used for routine surveillance. So the NPCR uses Summary Stage as its CS-derived stage.
