In a hospital-based cancer registry, the primary source of casefinding is ____________.

• A. Physician notes
• B. Pathology report documentation
• C. Discharge summaries
• D. Radiology reports

Answer: (B)

The primary source of casefinding in a hospital-based cancer registry is pathology report documentation because pathology provides the definitive histologic confirmation of a cancer diagnosis. This documentation gives essential details such as the exact site, histology, behavior, and the date of diagnosis, which are the critical elements registrars use for accurate inclusion and coding (ICD-O and other registry fields). Other sources like physician notes, discharge summaries, or radiology reports can raise suspicion or indicate a possible cancer, but they are less reliable on their own for establishing a confirmed diagnosis and may be ambiguous or incomplete. Pathology reports are the most consistent, authoritative records for identifying new cancer cases, making them the primary engine for casefinding.
