The World Health Organization (WHO) Digestive System Tumours, 6th Edition, has been released as an online beta version.

In synchrony with updates to the WHO Classification of Digestive System Tumours, the ICCR is updating eight existing datasets and developing six new datasets.

This is the first in the new 6th edition series (also known as the WHO Blue Books) which is regarded as the gold standard for the diagnosis of tumours and comprises a unique synthesis of histopathological diagnosis with digital and molecular pathology.
