Accreditation

RULES AND PROCEDURES FOR THE ACCREDITATION OF POPULATION REGISTRIES

A registry whose data is not yet included in the AIRTUM database must apply to the association’s secretary. AIRTUM will appoint a board of assessment within a month.
The board will issue a written judgement within three months of receiving the documents and material listed below. The board reserves the right to request further information which, if necessary, will be inspected at the offices of the applicant registry.
Reasons for possible delays to the judgement will be communicated to the secretary.
A condition of accreditation is that the registry must submit incidence data covering at least three consecutive years.

The following documentation and materials must be produced by the applicant registry:

  1. A copy of the incidence data under evaluation formatted according to the ‘BD’ standard (see table 1 below ).
  2. Files of mortality (individual and aggregrate data) and population with maximum possible data (preferably, with annual age classes from 0 to 90+ for individual years of registration.
  3. A completed ENCR questionnaire “Standards and Guidelines for Cancer Registration in Europe,” IARC Technical report No. 40.
  4. A table or file with the results of the “Check IARC” programme.
  5. A table or file of the numbers of incident cases, deceased in the period and age-specific rates (“Cancer in Italy” format).
  6. A table or file with total cases, raw rates, standardized rates (Italy ’81, standard world population, age-truncated) and cumulative risks up to 74 years (“Cancer in Italy” format).
  7. A table or file with the percentage of cases with histological, citological, clinical and DCO diagnosis (“Cancer in Italy” format).
  8. A table or file with ratios of mortality to incidence (“Cancer in Italy” format).
  9. A table or file with the distribution of the anatomical sub-site (“Cancer in Italy” format).
  10. A table or file with the distribution of the morphologies of the anatomical sites (“Cancer in Italy” format).
  11. A table or file with the totals of cases by residence, sex and year of registration.
  12. A table or file with the totals of DCO cases by residence, sex and year of registration.
  13. A table or file with the totals of cases with microscopic verification (histological and cytological) by residence, sex and year of registration.
  14. A table or file with the number of cases with histological diagnosis and unknown morphology (ICDO2-M “8000”) by residence and sex.
  15. All the material and the judgement are strictly confidential and can be circulated only among the members of the secretariat and the assessment board.

Note. The main integration concerns are:

  1. From which source among its information sources does the registry regularly take information (laboratories, radiological centres, file exemptions)?
  2. What criteria are used in the following situations?
    1. In which and in how many cases are there histological bases (IARC code 7) rather than cytological (IARC code 5) by a cytological sample method (fine needle aspiration, myelo-aspiration, thoracentesis, paracentesis, etc.)?
    2. What are the criteria applied by the registry in attributing behaviour codes (/1, /2 and /3) in cases of histological reports of epithelial cancers in which there is not an explicit report of the invasive state or the pT?
    3. In which cases does the registry attribute a specific morphological code on the basis of a diagnostic method other than microscopic (e.g., cancer of the SNC diagnosed through imaging)?
  3. What are the procedures for handling DCI?
  4. What are the procedures applied for following up cases (sources, criteria, definition dated from referral, active follow-up of subjects who have moved out of the area)?
  5. What is the institutional basis of the registry (regional resolution, business or other), and the staffing arrangement?
