TNM Supplement A Commentary on Uniform Use

The Union for International Cancer Controls (UICC) TNM classification system is the most widely used cancer classification and staging system in the world. It is used to describe the anatomical extent of disease and it is essential to patient care, research and cancer control.

This fifth edition of the TNM Supplement: A Commentary of Uniform Use offers practitioners a wealth of material intended to complement the systems day-to-day use. The volume features:

• Updated definitions of terms used in cancer staging.
• New sections on carcinomas of the thymus, sarcomas of the spine and pelvis and soft tissue sarcomas of the head and neck, and comprehensive updates to the head and neck carcinomas, carcinomas of the lung and neuroendocrine tumours sections.
• Frequently asked questions from the UICC helpdesk.

The Supplement may be treated as a companion text to the recent eighth edition of the TNM Classification of Malignant Tumours (978-1-119-26357-9), supporting the correct and uniform application of the TNM classification system. The TNM Supplement can also be utilised as a standalone book, providing explanations and examples to answer many questions that arise during the daily use of the TNM cancer classification and staging system, particularly in unusual cases.
