_______ are documents maintained by the cancer registry and form the basis for all of the registry operations.

• A. Records
• B. Cases
• C. Reports
• D. Abstracts

Answer: (D)

In a cancer registry, the essential unit of data is the abstract. An abstract is a standardized, concise summary of a patient’s cancer encounter, drawn from the medical record and other sources, and it includes key elements such as demographics, primary site, histology, behavior, stage, treatment, and follow-up status. This standardized summary becomes the registry’s primary data record for that case and feeds every registry activity. Why this is the best choice: Abstracts provide the uniform data structure that enables consistent coding, quality checks, analysis, and reporting across different facilities and time periods. They transform heterogeneous source documents into a single, analyzable record, allowing accurate incidence calculations, trends, survival analyses, and surveillance. Without abstracts, data would remain as scattered records without a uniform format, making reliable aggregation and comparison impossible. Records are the actual source documents, like the medical chart or pathology report. They are the raw materials, not the standardized data unit the registry uses for operations. Cases refer to each cancer event, but the registry operates on abstracts to conduct its processes. Reports are outputs produced from the registry data, not the basis for data collection itself.
