What does an inter-record edit compare?

An inter-record edit is a quality control process utilized in tumor registry systems to ensure data accuracy and consistency across multiple records. In this context, the correct answer focuses on comparing sequence numbers for a patient. This involves verifying that each record associated with a particular individual is numbered properly in accordance with the patient's treatment or tumor progression history, ensuring that any multiple tumors or events are systematically recorded and appropriately identified.

The proper sequence numbering helps maintain the integrity of the data, allowing registrars to track treatments, recurrences, and any relevant changes in the status of the patient. This process is critical for ensuring that researchers and clinicians can rely on tumor registry data for accurate patient follow-up and outcomes assessment.

In contrast, while the other options touch on important data elements (age, gender, medical history), they do not directly relate to the function of inter-record edits, which are specifically concerned with the organization and validation of records associated with a single patient's sequence in cancer registries.
