CTR Data Quality & Completeness 3

Question 1

When a cancer registry performs a casefinding audit using death certificates, the key measure calculated is:

Accepted Answer

Death certificate only (DCO) percentage

Answer

The DCO percentage from death certificate linkage indicates cases that were not captured prospectively, serving as a proxy for registry completeness.

Question 2

Which NAACCR data standard defines the required data items, their permitted codes, and edit specifications for central registry submissions?

Accepted Answer

NAACCR Volume II — Data Standards and Data Dictionary

Answer

NAACCR Volume II specifies data item definitions, coding instructions, and the edit set used to validate submissions to central registries.

Question 3

A registrar discovers that a surgical pathology report and a cytology report for the same patient describe different histologies. To ensure data quality, the registrar should:

Accepted Answer

Code the histology from the most specific specimen type, typically surgical pathology

Answer

SEER coding rules prioritize the most specific tissue diagnosis; surgical pathology generally supersedes cytology when both are available for the same site.

Question 4

Under CoC standards, what is the maximum number of days from date of first contact at a facility to the date a case must be abstracted?

Accepted Answer

6 months

Answer

CoC Standard 4.1 requires that cases be abstracted within 6 months of the date of first contact for analytic cases.

Question 5

A quality review reveals that a registrar consistently codes 'unknown' for Perineural Invasion when the pathology report does not explicitly mention it. The correct approach is to:

Accepted Answer

Code 'not applicable' or the appropriate 'not documented' code per SEER/STORE rules

Answer

Current coding manuals provide specific 'not documented' codes distinct from 'unknown,' and registrars should apply these accurately per item-specific instructions.
