The International Collaboration on Cancer Reporting (ICCR) produces common, internationally validated and evidence-based pathology datasets for cancer reporting for use throughout the world, through broad collaboration between Pathology Colleges, Societies and major cancer organisations internationally.

Global standardisation of pathology information on tumour classification, staging, prognostic and predictive information forms the basis for best practice in patient care and is a prerequisite for epidemiological research and benchmarking in cancer management both nationally and internationally.
