Confronted with myriads ofTs, N's and M's in the VICC TNM booklet, classifying a malignancy may seem to many cancer clini cians a tedious, dull and pedantic task. But then when he looks into the TNM-Atlas all of a sudden lifeless categories become vi vid images, challenging his know-how and his investigational skills. Prof. Dr. Brigit van der Werf-Messing, Chairman of the International TNM-Committee of the VICC. Preface In 1938 the League of Nations Health Organization published an "Atlas illustrating the division of cancer of the uterine cervix into four stages according to the anatomo-clinical extent of the growth". Since this work appeared, the idea of visual representation of the anatomical extent of malignant tumours at the different stages of their development has been repeatedly discussed. At its meeting in Copenhagen in July 1954, the VICC adopted as part of its programme "the realization of a clinical atlas". However, the time to do the planned illustration work was not ripe until the National Committees and international organiza tions had officially recognized the 28 classifications of malignant tumours at various sites as presented in the 3rd edition of the "TNM Booklet" (1978) edited by M. Harmer. This was all the more important since in 1980, in addition to the "Booklet", a "Brochure of Checklists" edited by A.H. Sellers was made available as a further aid in the practical application of the TNMsystem

Marvel at the wonders of the universe, from stars and planets to black holes and nebulae, in this exploration of our solar system and beyond. Universe opens with a look at astronomy and the history of the Universe, using 3D artworks to provide a comprehensive grounding in the fundamental concepts of astronomy, including the basic techniques of practical astronomy. The core of the book is a tour of the cosmos covering the Solar System, the Milky Way, and galaxies beyond our own. Explanatory pages introduce different celestial phenomena, such as galaxies, and are followed by catalogs that profile the most interesting and important examples. A comprehensive star atlas completes the picture, with entries on each of the 88 constellations and a monthly sky guide showing the night sky as it appears throughout the year as viewed from both the northern and southern hemispheres.

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.
