Publication of the WHO Classification of Tumours, 6th Edition, Volume 1: Digestive System Tumours

WHO Classification of Tumours: Digestive System Tumours is now available in print format.

Digestive System Tumours is the first volume in the 6th edition of the WHO Classification of Tumours series (the WHO Blue Books). This edition bridges evidence gaps and provides new images, ICD-O-4 codes, and updated diagnostic criteria that balance scientific advances with global relevance.

The WHO Blue Books remain the gold-standard reference books for tumour diagnosis. Offering a unique synthesis of histological, digital, and molecular pathology, they provide indispensable international standards for anyone involved in the care of patients with cancer or in cancer research, underpinning individual treatment as well as research into all aspects of cancer causation, prevention, therapy, and education.
