Why is interoperability important in cancer registry data?

• A. To allow different registries to exchange and use data consistently.
• B. To reduce the amount of data collected.
• C. To prevent sharing data with other agencies.
• D. To speed up manual data entry.

Answer: (A)

Interoperability is the ability of different information systems to exchange data and have that data be understood and used consistently. In cancer registries, this means data about a patient’s cancer—such as tumor site, histology, stage, treatment, and outcomes—can move between registries, hospitals, laboratories, and public health agencies without ambiguity. Achieving this relies on shared standards for what each data element means and how it is coded (for example, using standardized codes for tumor type and stage) and on common methods for transmitting data (like standardized formats and messaging protocols). When data are interoperable, registries can combine and compare information across regions, monitor incidence and survival more accurately, support quality improvement, and enable robust research and public health planning. The other options miss the core purpose: interoperability is not about reducing data, restricting sharing, or speeding up manual entry, but about seamless, meaningful data exchange.
