NAACCR Cancer Registry
NAACCRfree10 data-quality rules for cancer-incidence reporting in the NAACCR (North American Association of Central Cancer Registries) fixed-format / XML standard, submitted by facilities to central/state registries. Covers required NAACCR items, ICD-O-3 primary-site and histology value sets, sex and date validity, age plausibility, geography, reportability, and duplicate tumor suppression. Use it to validate abstracts before registry submission.
Checks included (10)
Primary Site Is Valid ICD-O-3
The primary site must be a valid ICD-O-3 topography code.
Histology Is Valid ICD-O-3 Morphology
The histology/morphology code must be a valid ICD-O-3 morphology code.
County FIPS Is Valid
The county at diagnosis must be a valid FIPS code for geographic attribution.
Required NAACCR Items Present
Each tumor record must carry the patient id, primary site, histology, and date of diagnosis.
Patient Identifier Present(patient_id)
Each abstract must carry a patient identifier for linkage and de-duplication.
Sex Code Is Valid(sex)
The NAACCR sex item must be a valid code (1 male, 2 female, 3–9 other/ unknown per the data dictionary).
Reportable Class of Case(class_of_case)
Class of case must be a reportable value (00–43 ranges per the NAACCR data dictionary); only reportable classes are submitted.
Diagnosis Date After Birth Date
Date of diagnosis cannot precede the patient's date of birth.
Age at Diagnosis Is Plausible(age_at_diagnosis)
Age at diagnosis should fall within 0–130 years (999 = unknown is handled separately).
No Duplicate Tumor Records(tumor_record_key)
A patient + tumor (sequence) should be reported once; duplicates over-count incidence.
