Although widespread travel and the internet have made the world a much ‘smaller’ place there have still been differences in the way we report the histopathology of cancers across the world. Most of these differences have been minor but some have been significant and have made comparative studies, e.g. prognosis related to stage, difficult. Recently the International Collaboration on Cancer Reporting (ICCR) has set up a number of working groups to produce standardised datasets for cancer in different organ systems. The latest dataset, on ovary, fallopian tube and primary peritoneal carcinoma, has just been published in Modern Pathology. With contributors from the UK, Australia, Canada, Norway, the Netherlands, Spain, Japan and the USA there is a wide geographical distribution and they have produced a well-designed evidence-based dataset.
