Which term refers to a nine-digit unique number in the hospital cancer registry system that identifies the patient?

• A. Case Number
• B. Medical Record Number
• C. Patient ID
• D. Accession Number

Answer: (D)

The key idea is how cancer registries uniquely identify a patient’s record across all related data. An accession number is the single, unique code assigned when a case is entered into the registry. This nine-digit identifier serves as the main link to pull together pathology reports, treatment information, follow-up data, and tumor details for that patient, keeping all pieces of the record connected even as other details change over time. It acts as a stable reference that isn’t tied to a patient’s name or to a hospital workflow, which helps protect privacy while ensuring data integrity across the registry. Medical Record Number identifies the patient within a specific hospital’s chart and may vary between institutions or over time, so it isn’t the universal registry key. A Case Number is often an internal label for a particular dataset or abstracting project and may not be consistently unique across the registry system. A Patient ID is a generic term that can refer to various identifiers and isn’t the standardized, registry-wide key. Therefore, the nine-digit, unique, registry-wide identifier described here is known as an accession number.
