The 5th edition, guided by the WHO Classification of Tumours Editorial Board, establishes a single coherent cancer classification presented across a collection of individual volumes organized on the basis of anatomical site (digestive system, breast, soft tissue and bone, etc.) and structured in a systematic manner, with each tumour type listed within a taxonomic classification: site, category, family (class), type, and subtype. In each volume, the entities are now listed from benign to malignant and are described under an updated set of headings, including histopathology, diagnostic molecular pathology, staging, and easy-to-read essential and desirable diagnostic criteria. (Fonte: editore) The WHO classification of endocrine and neuroendocrine tumours presented in this book reflects the views of the WHO Classification on tumours editorial board that convened via video conference 21-23 June 2021, as well as subsequent consultation.
