Revising the WHO classification: female genital tract tumours

The upcoming revision of the World Health Organisation (WHO) classification of tumours of the female genital tract is scheduled for release in the second quarter of 2020. It will feature significant changes compared to earlier editions. In this review, we outline the process of revising this important reference source for those diagnosing tumours or engaged in cancer research and describe the significant changes. TheWHO classification of tumoursis increasingly evidence-based, with a clear update cycle, improved quality of illustrations and content, led by an editorial board comprised mainly of pathologists, but increasingly incorporating input from other disciplines. The advent of the new website allows the use of whole-slide images and hyperlinks to evidence or external bodies that produce guidance on staging or reporting.
