Summary

Comparing multiple primary cancers (MPs) coding between registries is crucial. Adhering to international rules (IACR) significantly improves agreement and comparability for multiple primary cancers data.

Area of Science:

  • Oncology
  • Epidemiology
  • Biostatistics

Background:

  • Multiple primary cancers (MPs) lack a universal definition, hindering comparative studies.
  • Cancer registries use varying rules for accepting MPs, impacting data consistency.

Purpose of the Study:

  • To compare agreement on coding multiple primary cancers between the Danish Cancer Registry and the Tuscany Tumour Registry.
  • To assess if adopting common international rules (IACR) enhances comparability of MP data.

Main Methods:

  • Randomly extracted data from 200 patients with multiple cancers from two registries.
  • Coders from each registry initially used local rules, then applied IACR rules.
  • Calculated agreement using kappa statistics.

Main Results:

  • Good agreement (kappa = 0.70) using local MP coding rules.
  • Excluding discordant cases improved agreement (kappa = 0.86).
  • Very high agreement (kappa = 0.80) was achieved using IACR rules.

Conclusions:

  • International rules (IACR) significantly increase comparability for multiple primary cancers coding.
  • Cancer registries should adopt international standards or clearly state deviations for better data comparison.
