Which document is commonly used for cancer staging in registries?

• A. AJCC Cancer Staging Manual
• B. ICD-O
• C. NAACCR Standards
• D. MP/H

Answer: (A)

Staging is guided by a single, standardized reference that defines how to classify tumor extent using the TNM system and how those findings translate into stage groups. The AJCC Cancer Staging Manual provides the exact criteria for Tumor size/extent (T), lymph node involvement (N), and metastasis (M), plus the resulting stage groupings (0 through IV). In registries, this consistency lets stage data be comparable across hospitals and over time, which is essential for survival analyses and reporting stage distributions. Other options serve different roles: ICD-O codes are for describing the tumor’s site and histology, not its stage. NAACCR Standards cover data collection formats and variable definitions, not the staging rules themselves. MP/H focuses on documenting multiple primaries and histology details, not staging criteria.
