Which program is described as the only population-based cancer registry in the United States with longitudinal data on stage at diagnosis and survival?

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

Answer: (A)

The key idea is having a population-based registry that not only collects cancer cases but also tracks patients over time with detailed information on how advanced the cancer was when diagnosed and how long patients survive. Among US programs, the one designed to provide this combination across a defined population is the SEER program. SEER gathers incidence data from multiple regional registries and links it to mortality data, enabling longitudinal follow-up. This makes it possible to analyze stage at diagnosis and survival patterns over many years, by cancer type and other factors. The other options play different roles: NPCR centers on broad incidence data collection with less emphasis on long-term survival follow-up; NAACCR focuses on standards and data quality across registries; and CoC governs accreditation of cancer programs and their data practices, not population-based surveillance with stage and survival time.
