Which program is the only population-based registry in the United States that collects follow-up data enabling longitudinal analysis?

• A. NPCR
• B. CoC
• C. NAACCR
• D. SEER

Answer: (D)

Longitudinal analysis relies on follow-up data that track patients over time, including survival status and cause of death. SEER is designed as a population-based cancer registry that systematically collects and updates this follow-up information for a defined geographic population. It links cancer diagnoses to vital statistics and death records, using active and passive methods to keep status current, which allows researchers to analyze survival and outcomes across many years and across diverse groups. This continuous follow-up is what makes SEER particularly suited for longitudinal analyses. In contrast, other programs may focus more on incidence data or operate as facility-based registries, so they aren’t built around the same long-term follow-up framework.
