The Cancer Registry of Norway
Jan F Nygård
Head of the IT-department
Background
> Population-based cancer registry with national
coverage
> 150 employees
> Compulsory reporting of cancer cases since
1951 from the clinical community
> Personal identification number
> Correct coding of multiple primary tumours
> Follow up of patients for survival analysis
> Correct assessment of the denominators for cancer rates
through the population database
> Linkage with other sources for comparisons between groups
Legislation
> The Cancer Registry may without consent contain data relating to
persons who have or have had cancer, precancerous conditions,
or benign tumours in the central nervous system:

The Main database (since 1953)
> Number Patients:
1 222 602
> Number of diagnoses: 1 496 421
> Number of notifications: 3 612 896
> Number of new cases 2009: 27 520
> Data quality (2001-05)
> 98.8 % complete for all types of cancers combined
> 93,9 % morphologically verified
> 0,9 % obtained from death certificate only (DCO).
> Basis for the yearly publication “Cancer in Norway”
Trends, all cancer types combined
Clinical quality registries
> The main database contains data related to the initial
diagnosis
> Several additional clinical databases connected to the main
database are either already established or will soon be,
with a focus on treatment and longitudinal data

Clinical and descriptive research
> Projects related to the different clinical registries
> diagnostics, treatment and outcome quality
> evaluation of cancer care
> Time trend studies
> Prediction of future cancer burden
> Annual report: Cancer in Norway 2007:
“Long-term survival of cancer patients in Norway
1953-2006”
Example: Treatment of rectum
cancer
Proportion of local recurrence
1988
2004
28 %
9%
Key success factors:
> Introduction of new operation method (TME) with nationwide
training
> Establishment of a clinical registry for rectum cancer within
the Cancer Registry of Norway (CRN)
> Close collaboration between CRN and the clinical
community
> Feedback to the hospitals on their results
> Centralizing treatment

Screening-related research
> Evaluation of the mammography programme:
mortality changes, biological features, health
service logistics, quality of diagnostics and
treatment
> Vaccination against HPV infection of the cervix
> Evaluation of the cervix screening programme:
logistics, compliance, tests
> Colorectal cancer screening: adenoma/cancer,
life-style, quality of life, health economy, health
services, laboratory studies

Traditional cancer registration
Focus of
primary diagnosis
K: Clinical report
P: Patology report
D: Death certificate
Principles of registration
>
>
>
>
1st hand information
Independence of information
Collect information as they occur
Coding and classification adhere to agreed
international guidelines
With regard to comparability, completeness,
validity and timeliness
Traditional cancer registration
(plus)
Focus on time of
primary diagnosis
K: Clinical report
P: Patology report
D: Death certificate
N: Patient register report
So what is the difference between
a traditional cancer register and a
clinical/quality register?
Cancer registration
Clinical / quality - registries
Diagnosis
Time of relapse
Start of primary
treatment End of primary
treatment
Time of metastatic disease
D: Diagnostic report
S: Surgery report
R: Radiotherapy
C: Chemotherapy report
H: Hormonal therapy report
P: Patology report
D: Death certificate
N: Patient register report
Consequences for clinical and
health services research
> Quality indicators
> Are patients diagnosed according to
national guideslines
> Are patients treated according to
national guideslines
> Regional differences?
> Comparisons of treatment regiments
